They are created and managed by the Application Insights core. However, for advanced scenarios, you can use the `createOTelApi` function: + +### createOTelApi Function + +```typescript +function createOTelApi(otelApiCtx: IOTelApiCtx): IOTelApi; +``` + +**Parameters:** +- `otelApiCtx: IOTelApiCtx` - The context containing the host instance + +**Returns:** A new [`IOTelApi`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/IOTelApi.html) instance + +**Example:** +```typescript +import { createOTelApi } from '@microsoft/applicationinsights-core-js'; + +// Advanced: Create a custom OTel API instance +const otelApiCtx = { + host: appInsightsCore +}; + +const customOtelApi = createOTelApi(otelApiCtx); +``` + +### IOTelApiCtx Interface + +```typescript +export interface IOTelApiCtx { + /** + * The host instance (AppInsightsCore) that provides tracing capabilities + */ + host: ITraceHost; +} +``` + +## Usage Examples + +### Example 1: Basic API Access + +```typescript +import { ApplicationInsights } from '@microsoft/applicationinsights-web'; + +const appInsights = new ApplicationInsights({ + config: { + connectionString: 'YOUR_CONNECTION_STRING', + traceCfg: { + suppressTracing: false + } + } +}); +appInsights.loadAppInsights(); + +// Get the OTel API +const otelApi = appInsights.otelApi; + +// Access different parts of the API +console.log('Has trace API:', !!otelApi.trace); +console.log('Has host:', !!otelApi.host); +console.log('Configuration available:', !!otelApi.cfg); +``` + +### Example 2: Getting Tracers + +```typescript +const otelApi = appInsights.otelApi; + +// Get a tracer directly from the API +const tracer1 = otelApi.getTracer('service-a'); + +// Or get it via the trace property (recommended) +const tracer2 = otelApi.trace.getTracer('service-b'); + +// Both approaches work and return cached instances +const tracer3 = otelApi.trace.getTracer('service-a'); +console.log(tracer1 === tracer3); // true - same cached instance +``` + +### Example 3: Working with Active Spans + +```typescript +const otelApi = appInsights.otelApi; +const tracer = otelApi.trace.getTracer('my-app'); + +// Create and set an active span +const span = tracer.startSpan('operation'); +otelApi.trace.setActiveSpan(span); + +// Later, get the active span +const activeSpan = otelApi.trace.getActiveSpan(); +if (activeSpan) { + activeSpan.setAttribute('additional.info', 'added later'); +} + +// Clear the active span +otelApi.trace.setActiveSpan(null); +span.end(); +``` + +### Example 4: Span Context Utilities + +```typescript +const otelApi = appInsights.otelApi; + +// Check if a span context is valid +const spanContext = { + traceId: '00000000000000000000000000000001', + spanId: '0000000000000001', + traceFlags: 1 +}; + +if (otelApi.trace.isSpanContextValid(spanContext)) { + // Wrap the context in a non-recording span + const wrappedSpan = otelApi.trace.wrapSpanContext(spanContext); + + // Use the wrapped span (e.g., for context propagation) + otelApi.trace.setActiveSpan(wrappedSpan); + + // ... perform operations that should have this context + + otelApi.trace.setActiveSpan(null); +} +``` + +### Example 5: Multiple Service Components + +```typescript +const otelApi = appInsights.otelApi; + +// Define different tracers for different parts of your application +const tracers = { + userService: otelApi.trace.getTracer('user-service'), + paymentService: otelApi.trace.getTracer('payment-service'), + notificationService: otelApi.trace.getTracer('notification-service') +}; + +// Use the appropriate tracer for each operation +function authenticateUser(userId: string) { + const span = tracers.userService.startSpan('authenticate'); + span.setAttribute('user.id', userId); + // ... authentication logic + span.end(); +} + +function processPayment(amount: number) { + const span = tracers.paymentService.startSpan('process-payment'); + span.setAttribute('payment.amount', amount); + // ... payment logic + span.end(); +} + +function sendNotification(type: string) { + const span = tracers.notificationService.startSpan('send-notification'); + span.setAttribute('notification.type', type); + // ... notification logic + span.end(); +} +``` + +### Example 6: Accessing Configuration + +```typescript +const otelApi = appInsights.otelApi; + +// Check if tracing is enabled +function isTracingEnabled(): boolean { + return otelApi.cfg?.traceCfg?.suppressTracing !== true; +} + +// Conditionally create spans based on configuration +function createSpanIfEnabled(name: string): IReadableSpan | null { + if (!isTracingEnabled()) { + return null; + } + + const tracer = otelApi.trace.getTracer('my-service'); + return tracer.startSpan(name); +} + +// Use the conditional span creation +const span = createSpanIfEnabled('optional-trace'); +if (span) { + span.setAttribute('traced', true); + // ... do work + span.end(); +} +``` + +### Example 7: Integration with Host Methods + +```typescript +const otelApi = appInsights.otelApi; + +// Use host methods directly for lower-level control +const span = otelApi.host.startSpan('low-level-operation', { + kind: OTelSpanKind.INTERNAL, + attributes: { + 'operation.type': 'direct-host-call' + } +}); + +// Set it as active using the host +const scope = otelApi.host.setActiveSpan(span); + +try { + // Perform work with span active + console.log('Current trace context:', otelApi.host.getTraceCtx()); + + // Create child span (automatically uses active span as parent) + const childSpan = otelApi.host.startSpan('child-operation'); + childSpan?.end(); + +} finally { + // Restore previous context + scope?.restore(); + span.end(); +} +``` + +## Best Practices + +### 1. Prefer Direct startSpan for Most Scenarios + +**Recommended approach:** +```typescript +// Direct startSpan from AISKU - simplest for most use cases +appInsights.startSpan('operation-name', (span) => { + span.setAttribute('key', 'value'); + // operation code +}); +``` + +**Use getTracer for service organization:** +```typescript +// Only needed when organizing multiple services/components +const tracer = otelApi.trace.getTracer('my-service'); +tracer.startActiveSpan('operation', (span) => { + // ... +}); +``` + +### 2. Use the Trace API for Tracer Access + +**Recommended:** +```typescript +const tracer = otelApi.trace.getTracer('my-service'); +``` + +**Also Valid:** +```typescript +const tracer = otelApi.getTracer('my-service'); +``` + +Both work, but using `otelApi.trace.getTracer()` is more explicit and follows OpenTelemetry conventions. + +### 3. Cache the OTel API Reference + +```typescript +// Good - cache the reference +const otelApi = appInsights.otelApi; +const tracer = otelApi.trace.getTracer('my-service'); + +// Less efficient - repeated property access +appInsights.otelApi.trace.getTracer('my-service'); +``` + +### 4. Check for Null/Undefined + +While rare, always check for null when working with spans: + +```typescript +const span = tracer.startSpan('operation'); +if (span) { + // Safe to use span + span.setAttribute('key', 'value'); + span.end(); +} +``` + +### 5. Organize Tracers by Service/Component + +```typescript +// Good - clear organization +class UserService { + private tracer = otelApi.trace.getTracer('user-service'); + + authenticate(userId: string) { + const span = this.tracer.startSpan('authenticate'); + // ... + } +} + +class PaymentService { + private tracer = otelApi.trace.getTracer('payment-service'); + + processPayment(amount: number) { + const span = this.tracer.startSpan('process-payment'); + // ... + } +} +``` + +### 5. Use Configuration Safely + +```typescript +// Safe configuration access with fallbacks +function getTraceCfg(otelApi: IOTelApi): ITraceCfg | null { + return otelApi?.cfg?.traceCfg || null; +} + +// Check before using +const traceCfg = getTraceCfg(otelApi); +if (traceCfg && !traceCfg.suppressTracing) { + // Create spans +} +``` + +### 6. Prefer Trace API Methods Over Direct Host Access + +**Recommended:** +```typescript +const activeSpan = otelApi.trace.getActiveSpan(); +otelApi.trace.setActiveSpan(span); +``` + +**Direct (lower level):** +```typescript +const activeSpan = otelApi.host.getActiveSpan(); +otelApi.host.setActiveSpan(span); +``` + +The trace API methods provide better abstraction and follow OpenTelemetry conventions. + +## See Also + +- [Trace API Documentation](./traceApi.md) - Detailed tracer and span management +- [withSpan Helper](./withSpan.md) - Executing code with active span context +- [useSpan Helper](./useSpan.md) - Executing code with span scope parameter +- [Examples Guide](./examples.md) - Comprehensive usage examples +- [Main README](./README.md) - OpenTelemetry compatibility overview + +## Related Interfaces + +- [`IOTelConfig`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/IOTelConfig.html) - OpenTelemetry configuration settings +- [`ITraceHost`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/ITraceHost.html) - Host interface for span management +- [`ITraceApi`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/ITraceApi.html) - Trace API interface +- [`IOTelTracer`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/IOTelTracer.html) - Tracer interface for creating spans +- [`IOTelTracerProvider`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/IOTelTracerProvider.html) - Provider interface for getting tracers +- [`IOTelTracerOptions`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/IOTelTracerOptions.html) - Options for tracer creation diff --git a/docs/OTel/traceApi.md b/docs/OTel/traceApi.md new file mode 100644 index 000000000..3facc46f1 --- /dev/null +++ b/docs/OTel/traceApi.md @@ -0,0 +1,798 @@ +# Trace API Reference + +## Overview + +The [`ITraceApi`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/ITraceApi.html) interface provides the OpenTelemetry Trace API functionality for managing tracers and span contexts.

+ child1?.setAttribute('order', 1); + child1?.end(); + + const child2 = tracer.startSpan('child-2'); + child2?.setAttribute('order', 2); + child2?.end(); + + // Check active span + const active = trace.getActiveSpan(); + console.log('Active span:', active?.name); // 'parent-operation' + +} finally { + scope?.restore(); + parentSpan?.end(); +} +``` + +### Example 4: Context Propagation + +```typescript +const trace = otelApi.trace; + +// Extract context from current span +function getCurrentTraceContext(): IDistributedTraceContext | null { + const activeSpan = trace.getActiveSpan(); + return activeSpan ? activeSpan.spanContext() : null; +} + +// Propagate context to async operation +async function performAsyncWork(context: IDistributedTraceContext | null) { + if (context && trace.isSpanContextValid(context)) { + // Wrap and set as active + const wrappedSpan = trace.wrapSpanContext(context); + const scope = trace.setActiveSpan(wrappedSpan); + + try { + // Create child span with inherited context + const tracer = trace.getTracer('async-worker'); + const span = tracer.startSpan('async-operation'); + + // Work maintains trace context + await doAsyncWork(); + + span?.end(); + } finally { + scope?.restore(); + } + } +} + +// Usage +const context = getCurrentTraceContext(); +setTimeout(() => performAsyncWork(context), 1000); +``` + +### Example 5: Using startActiveSpan + +```typescript +const trace = otelApi.trace; +const tracer = trace.getTracer('my-service'); + +// Automatic span lifecycle management +async function processOrder(orderId: string) { + return tracer.startActiveSpan('process-order', async (span) => { + span.setAttribute('order.id', orderId); + + // All nested operations inherit this span context + const items = await fetchOrderItems(orderId); + span.setAttribute('order.items', items.length); + + const total = await calculateTotal(items); + span.setAttribute('order.total', total); + + return { orderId, items, total }; + // Span automatically ended when function returns + }); +} + +// Nested startActiveSpan calls +function nestedOperations() { + return tracer.startActiveSpan('parent', (parentSpan) => { + parentSpan.setAttribute('level', 1); + + return tracer.startActiveSpan('child', (childSpan) => { + childSpan.setAttribute('level', 2); + + // childSpan automatically has parentSpan as parent + console.log('Parent trace ID:', parentSpan.spanContext().traceId); + console.log('Child trace ID:', childSpan.spanContext().traceId); + // Both have the same trace ID + + return 'result'; + }); + }); +} +``` + +### Example 6: Conditional Tracing + +```typescript +const trace = otelApi.trace; +const tracer = trace.getTracer('my-service'); + +function conditionalTrace(operation: string, enabled: boolean) { + if (!enabled) { + // Perform operation without tracing + return performOperation(operation); + } + + // Trace the operation + return tracer.startActiveSpan(operation, (span) => { + span.setAttribute('traced', true); + return performOperation(operation); + }); +} + +// Check if currently being traced +function isCurrentlyTraced(): boolean { + return trace.getActiveSpan() !== null; +} + +// Conditionally add details +function addTraceDetails(key: string, value: any) { + const activeSpan = trace.getActiveSpan(); + if (activeSpan) { + activeSpan.setAttribute(key, value); + } +} + +// Usage +addTraceDetails('user.action', 'clicked-button'); +``` + +## Best Practices + +### 1. Prefer Direct startSpan from AISKU + +**Recommended approach:** +```typescript +// Direct startSpan from AISKU - simplest for most use cases +appInsights.startSpan('operation-name', (span) => { + span.setAttribute('key', 'value'); + // operation code +}); +``` + +**Use getTracer for service organization:** +```typescript +// Only needed when organizing multiple services/components +const tracer = otelApi.trace.getTracer('user-service'); +tracer.startActiveSpan('authenticate', (span) => { + // ... +}); +``` + +### 2. Cache Tracer Instances + +```typescript +// Good - cache tracers +class UserService { + private tracer = otelApi.trace.getTracer('user-service'); + + async authenticate(userId: string) { + return this.tracer.startActiveSpan('authenticate', async (span) => { + span.setAttribute('user.id', userId); + // ... + }); + } +} + +// Less efficient - create tracer each time +function authenticate(userId: string) { + const tracer = otelApi.trace.getTracer('user-service'); + // ... +} +``` + +### 3. Always Restore Context + +```typescript +// Good - always restore +const scope = trace.setActiveSpan(span); +try { + // ... operations +} finally { + scope?.restore(); + span.end(); +} + +// Bad - forgetting to restore can leak context +const scope = trace.setActiveSpan(span); +// ... operations +span.end(); // Forgot to restore! +``` + +### 4. Prefer startActiveSpan + +```typescript +// Recommended - automatic lifecycle +tracer.startActiveSpan('operation', (span) => { + span.setAttribute('key', 'value'); + return doWork(); +}); + +// Manual - requires careful management +const span = tracer.startSpan('operation'); +const scope = trace.setActiveSpan(span); +try { + span.setAttribute('key', 'value'); + return doWork(); +} finally { + scope?.restore(); + span.end(); +} +``` + +### 5. Validate External Context + +```typescript +// Good - validate before using +function handleExternalContext(context: any) { + if (trace.isSpanContextValid(context)) { + const span = trace.wrapSpanContext(context); + // Use span + } else { + console.warn('Invalid trace context received'); + } +} + +// Bad - assume context is valid +function handleExternalContext(context: any) { + const span = trace.wrapSpanContext(context); // May fail! +} +``` + +### 5. Use Meaningful Tracer Names + +```typescript +// Good - descriptive names +const authTracer = trace.getTracer('auth-service'); +const dbTracer = trace.getTracer('database-layer'); +const apiTracer = trace.getTracer('api-client'); + +// Less useful - generic names +const tracer1 = trace.getTracer('tracer'); +const tracer2 = trace.getTracer('app'); +``` + +### 6. Check for Active Span Before Adding Attributes + +```typescript +// Safe - check before using +function addContextInfo(key: string, value: any) { + const activeSpan = trace.getActiveSpan(); + if (activeSpan) { + activeSpan.setAttribute(key, value); + } +} + +// Works but creates unnecessary span +function addContextInfo(key: string, value: any) { + const span = tracer.startSpan('temp'); + span?.setAttribute(key, value); + span?.end(); // Creates telemetry unnecessarily +} +``` + +## See Also + +- [OTel API Documentation](./otelApi.md) - Main OpenTelemetry API interface +- [withSpan Helper](./withSpan.md) - Executing code with active span context +- [useSpan Helper](./useSpan.md) - Executing code with span scope parameter +- [Examples Guide](./examples.md) - Comprehensive usage examples +- [Main README](./README.md) - OpenTelemetry compatibility overview + +## Related Interfaces + +- [`ITraceApi`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/ITraceApi.html) - Trace API interface +- [`IOTelTracer`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/IOTelTracer.html) - Tracer interface for creating spans +- [`IReadableSpan`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/IReadableSpan.html) - Span interface +- [`IOTelSpanOptions`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/IOTelSpanOptions.html) - Options for span creation +- [`IDistributedTraceContext`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/IDistributedTraceContext.html) - Distributed trace context +- [`ISpanScope`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/ISpanScope.html) - Scope for restoring active span context diff --git a/docs/OTel/useSpan.md b/docs/OTel/useSpan.md new file mode 100644 index 000000000..0d45eef25 --- /dev/null +++ b/docs/OTel/useSpan.md @@ -0,0 +1,804 @@ +# useSpan Helper Function + +## Overview + +The `useSpan` helper function is similar to `withSpan` but provides the [`ISpanScope`](https://microsoft.github.io/ApplicationInsights-JS/webSdk/applicationinsights-core-js/interfaces/ISpanScope.html) object as the first parameter to your callback function.

Manual Context Control + +Unlike `withSpan`, you can manually restore the context within your callback if needed. + +```typescript +useSpan(core, span, (scope) => { + // Do some work with span active + doWork(); + + // Manually restore early if needed + scope.restore(); + + // Continue with previous context + doMoreWork(); +}); +``` + +### 4. Exception Safety + +Ensures the previous active span is restored even if the callback throws an error. + +### 5. Async Support + +Automatically handles both synchronous and asynchronous callbacks, including Promise-based functions. + +## Comparison with withSpan + +The main difference between `useSpan` and `withSpan` is how they pass parameters to the callback function. + +### withSpan + +Does NOT pass the scope to the callback: + +```typescript +withSpan(core, span, (arg1, arg2) => { + // arg1 and arg2 are your custom arguments + // No access to scope + console.log(arg1, arg2); +}, null, 'value1', 'value2'); +``` + +### useSpan + +Passes the scope as the FIRST parameter: + +```typescript +useSpan(core, span, (scope, arg1, arg2) => { + // scope is the ISpanScope object + // arg1 and arg2 are your custom arguments + console.log(scope, arg1, arg2); + + // Can manually restore + scope.restore(); +}, null, 'value1', 'value2'); +``` + +**When to use which:** + +| Use `withSpan` | Use `useSpan` | +|----------------|---------------| +| Don't need scope access | Need to manually restore context | +| Simple callback execution | Need scope for advanced scenarios | +| Most common scenarios | Complex context management | +| Cleaner callback signature | Need explicit control | + +## Usage Examples + +### Example 1: Basic Usage + +```typescript +import { ApplicationInsights } from '@microsoft/applicationinsights-web'; +import { useSpan } from '@microsoft/applicationinsights-core-js'; + +const appInsights = new ApplicationInsights({ + config: { + connectionString: 'YOUR_CONNECTION_STRING' + } +}); +appInsights.loadAppInsights(); + +const tracer = appInsights.trace.getTracer('my-service'); + +// Create a span +const span = tracer.startSpan('operation'); + +// Execute code with span as active context +const result = useSpan(appInsights, span, (scope) => { + span.setAttribute('step', 'processing'); + + // Perform work - span is active during execution + const data = processData(); + + span.setAttribute('result', 'success'); + return data; +}); + +span.end(); +``` + +### Example 2: Manual Context Restoration + +```typescript +const span = tracer.startSpan('complex-operation'); + +useSpan(appInsights, span, (scope) => { + span.setAttribute('phase', 'with-context'); + + // Do work with span active + performWorkWithContext(); + + // Manually restore context early + scope.restore(); + + span.setAttribute('phase', 'without-context'); + + // Continue work with previous context + performWorkWithoutContext(); +}); + +span.end(); +``` + +### Example 3: Conditional Context Restoration + +```typescript +const span = tracer.startSpan('conditional-context'); + +useSpan(core, span, (scope, shouldRestoreEarly) => { + span.setAttribute('processing', true); + + doInitialWork(); + + if (shouldRestoreEarly) { + console.log('Restoring context early'); + scope.restore(); + } + + // If restored early, runs with previous context + // Otherwise, runs with span context + doAdditionalWork(); +}, null, true); // Pass shouldRestoreEarly = true + +span.end(); +``` + +### Example 4: Async Operations + +```typescript +const span = tracer.startSpan('async-operation'); + +const result = await useSpan(core, span, async (scope) => { + span.setAttribute('started', Date.now()); + + // Async work + const response = await fetch('/api/data'); + const data = await response.json(); + + span.setAttribute('completed', Date.now()); + span.setAttribute('items', data.length); + + return data; +}); + +span.end(); +console.log('Result:', result); +``` + +### Example 5: Accessing Scope Properties + +```typescript +const span = tracer.startSpan('scope-access'); + +useSpan(core, span, (scope) => { + // Access scope properties + console.log('Scope type:', typeof scope); + console.log('Has restore method:', typeof scope.restore === 'function'); + + // Perform work + span.setAttribute('scope.available', true); + + // Demonstrate manual restore + const shouldRestoreNow = checkCondition(); + if (shouldRestoreNow) { + scope.restore(); + } +}); + +span.end(); +``` + +### Example 6: Passing Additional Arguments + +```typescript +function processWithContext( + scope: ISpanScope, + userId: string, + action: string +): string { + console.log('Scope:', scope); + return `User ${userId} performed ${action}`; +} + +const span = tracer.startSpan('user-action'); + +// Pass additional arguments to callback +const result = useSpan( + core, + span, + processWithContext, + null, // thisArg + 'user123', // userId + 'checkout' // action +); + +span.end(); +console.log(result); // 'User user123 performed checkout' +``` + +### Example 7: Error Handling with Manual Restoration + +```typescript +const span = tracer.startSpan('error-handling'); + +try { + useSpan(core, span, (scope) => { + span.setAttribute('attempting', true); + + try { + performRiskyOperation(); + span.setStatus({ code: SpanStatusCode.OK }); + } catch (error) { + // Record error and restore context before handling + span.recordException(error); + span.setStatus({ code: SpanStatusCode.ERROR }); + + // Restore context before error propagates + scope.restore(); + + throw error; + } + }); +} catch (error) { + // Context already restored + console.error('Operation failed:', error); +} finally { + span.end(); +} +``` + +### Example 8: Nested Spans with Manual Control + +```typescript +const parentSpan = tracer.startSpan('parent-operation'); + +useSpan(core, parentSpan, (parentScope) => { + parentSpan.setAttribute('level', 1); + + // Create child span + const childSpan = tracer.startSpan('child-operation'); + + useSpan(core, childSpan, (childScope) => { + childSpan.setAttribute('level', 2); + + // Access both scopes + console.log('Parent scope:', parentScope); + console.log('Child scope:', childScope); + + // Perform work + doNestedWork(); + + // Could manually restore child scope if needed + // childScope.restore(); + }); + + childSpan.end(); + + // Parent scope is still active here + console.log('Back to parent context'); +}); + +parentSpan.end(); +``` + +### Example 9: Complex Async Flow + +```typescript +const span = tracer.startSpan('complex-async'); + +await useSpan(core, span, async (scope) => { + span.setAttribute('stage', 'initial'); + + // Phase 1: With span context + await performPhase1(); + + // Conditionally restore based on async result + const shouldContinueWithContext = await checkContinuation(); + + if (!shouldContinueWithContext) { + scope.restore(); + span.setAttribute('context.restored.early', true); + } + + // Phase 2: Might be with or without context + await performPhase2(); + + span.setAttribute('stage', 'completed'); +}); + +span.end(); +``` + +### Example 10: Scope Inspection + +```typescript +const span = tracer.startSpan('scope-inspection'); + +useSpan(core, span, (scope) => { + // Inspect scope + console.log('Scope available:', !!scope); + console.log('Scope has restore:', 'restore' in scope); + + // Log current state + const currentSpan = core.getActiveSpan(); + console.log('Current span matches:', currentSpan === span); + + // Perform work + doWork(); + + // Demonstrate restoration + console.log('Before restore - active span:', core.getActiveSpan()?.name); + scope.restore(); + console.log('After restore - active span:', core.getActiveSpan()?.name); +}); + +span.end(); +``` + +## Best Practices + +### 1. Only Use useSpan When You Need the Scope + +```typescript +// Good - need scope for manual restore +useSpan(core, span, (scope) => { + doWork(); + if (needsEarlyRestore()) { + scope.restore(); + } + doMoreWork(); +}); + +// Better - use withSpan if scope not needed +withSpan(core, span, () => { + doWork(); + doMoreWork(); +}); +``` + +### 2. Be Careful with Manual Restoration + +```typescript +// Good - restore at the right time +useSpan(core, span, (scope) => { + doWorkNeedingContext(); + scope.restore(); + doWorkNotNeedingContext(); +}); + +// Bad - restoring too early +useSpan(core, span, (scope) => { + scope.restore(); // Too early! + doWorkNeedingContext(); // Context already gone +}); +``` + +### 3. Don't Restore Multiple Times + +```typescript +// Good - restore once +useSpan(core, span, (scope) => { + doWork(); + scope.restore(); +}); + +// Bad - multiple restores +useSpan(core, span, (scope) => { + scope.restore(); + // ... more code ... + scope.restore(); // Second restore - unexpected behavior! +}); +``` + +### 4. Always End Spans + +```typescript +// Good - span is ended +const span = tracer.startSpan('operation'); +try { + useSpan(core, span, (scope) => { + // Work + }); +} finally { + span.end(); +} + +// Bad - span is never ended +const span = tracer.startSpan('operation'); +useSpan(core, span, (scope) => { + // Work +}); // Forgot to end span! +``` + +### 5. Use with startSpan, Not startActiveSpan + +```typescript +// Good - use useSpan with startSpan +const span = tracer.startSpan('operation'); +useSpan(core, span, (scope) => { + // Work +}); +span.end(); + +// Redundant - startActiveSpan already manages context +tracer.startActiveSpan('operation', (span) => { + // No need for useSpan here +}); +``` + +### 6. Handle Async Carefully + +```typescript +// Good - proper async handling +const span = tracer.startSpan('async-op'); +try { + await useSpan(core, span, async (scope) => { + await doAsyncWork(); + }); +} finally { + span.end(); +} + +// Bad - not awaiting +const span = tracer.startSpan('async-op'); +useSpan(core, span, async (scope) => { + await doAsyncWork(); +}); // Not awaited! +span.end(); // Ends before async work completes +``` + +## Common Patterns + +### Pattern 1: Conditional Context Management + +```typescript +function executeWithOptionalContext( + span: IReadableSpan, + fn: () => T, + keepContextActive: boolean +): T { + return useSpan(core, span, (scope) => { + const result = fn(); + + if (!keepContextActive) { + scope.restore(); + } + + return result; + }); +} + +// Usage +executeWithOptionalContext(span, doWork, false); // Restores context +executeWithOptionalContext(span, doWork, true); // Keeps context +``` + +### Pattern 2: Scope-Aware Wrapper + +```typescript +function withManagedScope( + operationName: string, + fn: (scope: ISpanScope) => T +): T { + const span = tracer.startSpan(operationName); + try { + return useSpan(core, span, fn); + } finally { + span.end(); + } +} + +// Usage +withManagedScope('my-operation', (scope) => { + console.log('Have scope:', scope); + // Can manually restore if needed + return performWork(); +}); +``` + +### Pattern 3: Early Exit with Restoration + +```typescript +function processWithEarlyExit(data: any): any { + const span = tracer.startSpan('process'); + + return useSpan(core, span, (scope) => { + if (!validateData(data)) { + scope.restore(); + span.end(); + return null; // Early exit + } + + const result = processData(data); + span.end(); + return result; + }); +} +``` + +### Pattern 4: Scope Delegation + +```typescript +function delegateWithScope( + span: IReadableSpan, + operation: (restore: () => void) => T +): T { + return useSpan(core, span, (scope) => { + // Delegate restore capability to the operation + return operation(() => scope.restore()); + }); +} + +// Usage +delegateWithScope(span, (restore) => { + doWork(); + + if (shouldStop()) { + restore(); // Operation controls restoration + return null; + } + + return continueWork(); +}); +``` + +## Error Handling + +### Automatic Context Restoration on Error + +`useSpan` guarantees context restoration even when errors occur: + +```typescript +const previousSpan = core.getActiveSpan(); +const span = tracer.startSpan('operation'); + +try { + useSpan(core, span, (scope) => { + throw new Error('Operation failed'); + }); +} catch (error) { + // Context is restored to previousSpan + console.log(core.getActiveSpan() === previousSpan); // true +} finally { + span.end(); +} +``` + +### Manual Restoration Before Error + +```typescript +const span = tracer.startSpan('operation'); + +try { + useSpan(core, span, (scope) => { + try { + performRiskyOperation();

Context Restoration + +Ensures the previous active span is restored even if the callback throws an error. + +```typescript +const previousSpan = core.getActiveSpan(); + +try { + withSpan(core, span, () => { + throw new Error('Something went wrong'); + }); +} catch (error) { + // Previous span is still restored + console.log(core.getActiveSpan() === previousSpan); // true +} +``` + +### 3. Exception Safety + +Uses try-finally blocks internally to guarantee context restoration. + +### 4. Async Support + +Automatically handles both synchronous and asynchronous callbacks, including Promise-based functions. + +```typescript +// Async callback +await withSpan(core, span, async () => { + await doAsyncWork(); + // Context restored after promise settles +}); +``` + +### 5. Nested Span Support + +Handles complex span hierarchies automatically through proper context stacking. + +```typescript +withSpan(core, parentSpan, () => { + // parentSpan is active + + withSpan(core, childSpan, () => { + // childSpan is active + }); + + // parentSpan is active again +}); +``` + +## Usage Examples + +### Example 1: Basic Usage + +```typescript +import { ApplicationInsights } from '@microsoft/applicationinsights-web'; +import { withSpan } from '@microsoft/applicationinsights-core-js'; + +const appInsights = new ApplicationInsights({ + config: { + connectionString: 'YOUR_CONNECTION_STRING' + } +}); +appInsights.loadAppInsights(); + +const tracer = appInsights.trace.getTracer('my-service'); + +// Create a span +const span = tracer.startSpan('operation'); + +// Execute code with span as active context +const result = withSpan(appInsights, span, () => { + span.setAttribute('step', 'processing'); + + // Perform work - span is active during execution + const data = processData(); + + span.setAttribute('result', 'success'); + return data; +}); + +span.end(); +``` + +### Example 2: Async Operations + +```typescript +const span = tracer.startSpan('async-operation'); + +const result = await withSpan(appInsights, span, async () => { + span.setAttribute('started', Date.now()); + + // Async work + const response = await fetch('/api/data'); + const data = await response.json(); + + span.setAttribute('completed', Date.now()); + span.setAttribute('items', data.length); + + return data; +}); + +span.end(); +console.log('Result:', result); +``` + +### Example 3: Nested Spans + +```typescript +const parentSpan = tracer.startSpan('parent-operation'); + +withSpan(core, parentSpan, () => { + parentSpan.setAttribute('level', 1); + + // Create child span + const childSpan = tracer.startSpan('child-operation'); + + withSpan(core, childSpan, () => { + childSpan.setAttribute('level', 2); + + // childSpan automatically has parentSpan as parent + console.log('Parent ID:', parentSpan.spanContext().spanId); + console.log('Child parent ID:', childSpan.spanContext().spanId); + }); + + childSpan.end(); +}); + +parentSpan.end(); +``` + +### Example 4: Passing Additional Arguments + +```typescript +function processWithContext(userId: string, action: string): string { + return `User ${userId} performed ${action}`; +} + +const span = tracer.startSpan('user-action'); + +// Pass additional arguments to callback +const result = withSpan( + core, + span, + processWithContext, + null, // thisArg + 'user123', // userId + 'checkout' // action +); + +span.end(); +console.log(result); // 'User user123 performed checkout' +``` + +### Example 5: Custom This Context + +```typescript +class UserService { + private userId: string; + + constructor(userId: string) { + this.userId = userId; + } + + process(): string { + return `Processing for user ${this.userId}`; + } +} + +const service = new UserService('user123'); +const span = tracer.startSpan('service-operation'); + +// Preserve 'this' context +const result = withSpan( + core, + span, + service.process, + service // Use service as 'this' +); + +span.end(); +console.log(result); // 'Processing for user user123' +``` + +### Example 6: Error Handling + +```typescript +const span = tracer.startSpan('risky-operation'); + +try { + withSpan(core, span, () => { + span.setAttribute('attempting', true); + + // Operation that might throw + const result = performRiskyOperation(); + + span.setStatus({ code: SpanStatusCode.OK }); + span.setAttribute('success', true); + + return result; + }); +} catch (error) { + span.recordException(error); + span.setStatus({ + code: SpanStatusCode.ERROR, + message: error.message + }); + span.setAttribute('success', false); +} finally { + span.end(); // Always end the span +} +``` + +### Example 7: Multiple Nested Operations + +```typescript +const operationSpan = tracer.startSpan('complete-checkout'); + +withSpan(core, operationSpan, async () => { + operationSpan.setAttribute('step', 'starting'); + + // Validate user + const validateSpan = tracer.startSpan('validate-user'); + await withSpan(core, validateSpan, async () => { + validateSpan.setAttribute('user.id', '12345'); + await validateUser(); + }); + validateSpan.end(); + + // Process payment + const paymentSpan = tracer.startSpan('process-payment'); + await withSpan(core, paymentSpan, async () => { + paymentSpan.setAttribute('amount', 99.99); + await processPayment(); + }); + paymentSpan.end(); + + // Send confirmation + const confirmSpan = tracer.startSpan('send-confirmation'); + await withSpan(core, confirmSpan, async () => { + confirmSpan.setAttribute('notification.type', 'email'); + await sendConfirmation(); + }); + confirmSpan.end(); + + operationSpan.setAttribute('step', 'completed'); +}); + +operationSpan.end(); +``` + +### Example 8: Background Task + +```typescript +const span = tracer.startSpan('background-task'); + +// Execute background work with trace context +withSpan(core, span, async () => { + span.setAttribute('task.type', 'data-sync'); + span.setAttribute('started', new Date().toISOString()); + + // All operations here inherit span context + await syncDataToDatabase(); + + span.setAttribute('completed', new Date().toISOString()); +}); + +span.end(); +``` + +### Example 9: Conditional Execution + +```typescript +function executeWithTracing(operation: () => void, shouldTrace: boolean) { + if (!shouldTrace) { + // Execute without tracing + return operation(); + } + + // Execute with tracing + const span = tracer.startSpan('conditional-operation'); + try { + return withSpan(core, span, operation); + } finally { + span.end(); + } +} + +// Usage +executeWithTracing(() => { + console.log('This is traced'); +}, true); + +executeWithTracing(() => { + console.log('This is not traced'); +}, false); +``` + +### Example 10: Integration with Existing Code + +```typescript +// Existing function without tracing +async function fetchUserData(userId: string) { + const response = await fetch(`/api/users/${userId}`); + return response.json(); +} + +// Add tracing without modifying the function +async function fetchUserDataWithTracing(userId: string) { + const span = tracer.startSpan('fetch-user-data'); + span.setAttribute('user.id', userId); + + try { + const result = await withSpan(core, span, () => { + return fetchUserData(userId); + }); + + span.setStatus({ code: SpanStatusCode.OK }); + return result; + } catch (error) { + span.recordException(error); + span.setStatus({ code: SpanStatusCode.ERROR }); + throw error; + } finally { + span.end(); + } +} +``` + +## Comparison with useSpan + +`withSpan` and `useSpan` are similar but differ in how they pass parameters to the callback function. + +### withSpan + +Passes additional arguments directly to the callback: + +```typescript +withSpan(core, span, (arg1, arg2) => { + // arg1 and arg2 are your custom arguments + console.log(arg1, arg2); +}, null, 'value1', 'value2'); +``` + +### useSpan + +Passes the `ISpanScope` as the first argument: + +```typescript +useSpan(core, span, (scope, arg1, arg2) => { + // scope is the ISpanScope + // arg1 and arg2 are your custom arguments + console.log(scope, arg1, arg2); +}, null, 'value1', 'value2'); +``` + +**When to use which:** +- **`withSpan`**: When you don't need access to the span scope object +- **`useSpan`**: When you need to manually restore context or access scope properties + +See the [useSpan documentation](./useSpan.md) for more details. + +## Best Practices + +### 1. Always End Spans + +```typescript +// Good - span is ended +const span = tracer.startSpan('operation'); +try { + withSpan(core, span, () => { + // Work + }); +} finally { + span.end(); +} + +// Bad - span is never ended +const span = tracer.startSpan('operation'); +withSpan(core, span, () => { + // Work +}); // Forgot to end span! +``` + +### 2. Use with startSpan, Not startActiveSpan + +```typescript +// Good - use withSpan with startSpan +const span = tracer.startSpan('operation'); +withSpan(core, span, () => { + // Work +}); +span.end(); + +// Redundant - startActiveSpan already manages context +tracer.startActiveSpan('operation', (span) => { + // No need for withSpan here +}); +``` + +### 3. Handle Errors Appropriately + +```typescript +const span = tracer.startSpan('operation'); +try { + withSpan(core, span, () => { + // Work that might throw + throw new Error('Failed'); + }); +} catch (error) { + // Record exception + span.recordException(error); + span.setStatus({ code: SpanStatusCode.ERROR }); +} finally { + span.end(); +} +``` + +### 4. Don't Nest withSpan Unnecessarily + +```typescript +// Good - each span with its own withSpan +const span1 = tracer.startSpan('operation-1'); +withSpan(core, span1, () => { + // Work +}); +span1.end(); + +const span2 = tracer.startSpan('operation-2'); +withSpan(core, span2, () => { + // Work +}); +span2.end(); + +// Less ideal - unnecessary nesting +withSpan(core, span1, () => { + withSpan(core, span1, () => { // Redundant + // Work + }); +}); +``` + +### 5. Combine with Async/Await + +```typescript +// Good - natural async/await usage +const span = tracer.startSpan('async-op'); +try { + const result = await withSpan(core, span, async () => { + return await doAsyncWork(); + }); + span.setStatus({ code: SpanStatusCode.OK }); +} finally { + span.end(); +} +``` + +## Common Patterns + +### Pattern 1: Wrapper Functions + +```typescript +function withTracing( + operationName: string, + fn: () => T +): T { + const span = tracer.startSpan(operationName); + try { + return withSpan(core, span, fn); + } finally { + span.end(); + } +} + +// Usage +const result = withTracing('my-operation', () => { + return performWork(); +}); +``` + +### Pattern 2: Decorator Pattern + +```typescript +function traced(operationName: string) { + return function( + target: any, + propertyKey: string, + descriptor: PropertyDescriptor + ) { + const original = descriptor.value; + + descriptor.value = function(...args: any[]) { + const span = tracer.startSpan(operationName); + try { + return withSpan(core, span, () => { + return original.apply(this, args); + }, this); + } finally { + span.end(); + } + }; + + return descriptor; + }; +} + +// Usage +class MyService { + @traced('process-data') + processData(data: any) { + // Automatically traced + return data.processed; + } +} +``` + +### Pattern 3: Context Preservation + +```typescript +function preserveContext(fn: () => T): () => T { + const span = core.getActiveSpan(); + + return () => { + if (span) { + return withSpan(core, span, fn); + } + return fn(); + }; +} + +// Usage +const contextualFn = preserveContext(() => { + console.log('Maintaining trace context'); +}); + +setTimeout(contextualFn, 1000); // Executes with preserved context +``` + +## Error Handling + +### Automatic Context Restoration + +`withSpan` guarantees context restoration even when errors occur: + +```typescript +const previousSpan = core.getActiveSpan(); +const span = tracer.startSpan('operation'); + +try { + withSpan(core, span, () => { + throw new Error('Operation failed'); + }); +} catch (error) { + // Context is restored to previousSpan + console.log(core.getActiveSpan() === previousSpan); // true +} finally { + span.end(); +} +``` + +### Error Recording + +```typescript +const span = tracer.startSpan('operation'); + +try { + withSpan(core, span, () => { + try { + performRiskyOperation(); + span.setStatus({ code: SpanStatusCode.OK }); + } catch (error) { + span.recordException(error); + span.setStatus({ code: SpanStatusCode.ERROR }); + throw error; // Re-throw if needed + } + }); +} catch (error) { + // Handle error at outer level + console.error('Operation failed:', error); +} finally { + span.end(); +} +``` + +### Promise Rejection + +```typescript +const span = tracer.startSpan('async-operation'); + +try { + await withSpan(core, span, async () => { + const result = await fetch('/api/data'); + if (!result.ok) { + throw new Error(`HTTP ${result.status}`); + } + return result.json(); + }); + span.setStatus({ code: SpanStatusCode.OK }); +} catch (error) { + span.recordException(error); + span.setStatus({ code: SpanStatusCode.ERROR }); +} finally { + span.end(); +} +``` + +## See Also + +- [useSpan Helper](./useSpan.md) - Similar helper with scope parameter +- [Trace API Documentation](./traceApi.md) - Tracer and span management +- [OTel API Documentation](./otelApi.md) - Main OpenTelemetry API +- [Examples Guide](./examples.md) - Comprehensive usage examples +- [Main README](./README.md) - OpenTelemetry compatibility overview + +## Related Types + +- `ITraceHost` - Host interface for span management +- `IReadableSpan` - Span interface +- `ISpanScope` - Scope for restoring active span context +- `IOTelTracer` - Tracer interface for creating spans diff --git a/docs/README.md b/docs/README.md index b733ca717..cace719fb 100644 --- a/docs/README.md +++ b/docs/README.md @@ -41,6 +41,7 @@ ES3 support has been removed from the latest version (v3.x), if required [see fo ### Docs +- [OpenTelemetry Tracing API](./OTel/README.md) - OpenTelemetry-compatible tracing API for distributed tracing - [Performance Monitoring](./PerformanceMonitoring.md) - [Dependency Listeners](./Dependency.md) - [SDK Load Failure](./SdkLoadFailure.md) diff --git a/examples/AISKU/src/utils.ts b/examples/AISKU/src/utils.ts index c47cf089d..48476e11e 100644 --- a/examples/AISKU/src/utils.ts +++ b/examples/AISKU/src/utils.ts @@ -1,8 +1,7 @@ // Copyright (c) Microsoft Corporation.

1. ✅ Removed AppInsightsTraceProvider Class +- **File**: `AISKU/src/OpenTelemetry/trace/AppInsightsTraceProvider.ts` +- **Change**: Replaced the `AppInsightsTraceProvider` class with a factory function `createTraceProvider()` +- **Reason**: The main AISKU should internally implement this during initialization rather than exporting a class + +### 2. ✅ Removed AppInsightsSpan Class +- **File**: `AISKU/src/OpenTelemetry/trace/span.ts` +- **Change**: + - Removed the `AppInsightsSpan` class + - Implemented span functionality inline in the `createSpan` factory function using closure-based approach + - Added `SpanEndCallback` type for handling span end events +- **Reason**: Eliminates class overhead and makes the implementation more internal + +### 3. ✅ Made createSpan Internal-Only +- **File**: `AISKU/src/OpenTelemetry/trace/span.ts` +- **Change**: + - Made `createSpan` function internal (not exported from package) + - Added `onSpanEnd` callback parameter to support trace provider integration + - Span `end()` function now calls back into the provided callback function +- **Reason**: Factory function should be internal and support telemetry event creation + +### 4. ✅ Updated Package Exports +- **File**: `AISKU/src/applicationinsights-web.ts` +- **Change**: Removed exports for `AppInsightsSpan`, `createSpan`, and `AppInsightsTraceProvider` +- **Reason**: These should be internal-only implementations + +### 5. ✅ Integrated Trace Provider in AISKU Initialization +- **File**: `AISKU/src/AISku.ts` +- **Change**: + - Added trace provider setup in the `loadAppInsights` initialization function + - Created span end callback that converts span data to telemetry using `trackTrace` + - Set the trace provider on the core using `_core.setTraceProvider()` +- **Reason**: Main AISKU should internally implement and configure the trace provider + +## Technical Implementation Details + +### Inline Span Implementation +The span is now implemented using closures instead of a class: + +```typescript +function createSpan(name, parent, options, onSpanEnd) { + // Private variables in closure + let _spanContext = spanContext; + let _attributes = {}; + let _name = name; + let _ended = false; + + // Return span implementation object + const span = { + spanContext: () => _spanContext, + setAttribute: (key, value) => { /* implementation */ }, + setAttributes: (attributes) => { /* implementation */ }, + updateName: (newName) => { /* implementation */ }, + end: (endTime) => { + if (!_ended) { + _ended = true; + _endTime = endTime || utcNow(); + + // Call the end callback if provided + if (onSpanEnd) { + onSpanEnd(span, _endTime); + } + } + }, + isRecording: () => !_ended + }; + + return span; +} +``` + +### Span End Callback Integration +When a span ends, it calls back to the AISKU which creates telemetry: + +```typescript +const traceProvider = createTraceProvider((span, endTime) => { + const spanData = span as any; // Access helper methods + if (spanData.getName && spanData.getAttributes) { + const name = spanData.getName(); + const attributes = spanData.getAttributes(); + + // Create trace telemetry for the span + _self.trackTrace({ + message: `Span: ${name}`, + severityLevel: 1, + properties: { + ...attributes, + spanId: span.spanContext().spanId, + traceId: span.spanContext().traceId, + startTime: spanData.getStartTime().toString(), + endTime: endTime.toString(), + duration: (endTime - spanData.getStartTime()).toString() + } + }); + } +}); +``` + +## Benefits + +1. **Simplified Architecture**: No longer exposes internal span classes +2. **Better Encapsulation**: Span implementation is truly internal to the SDK +3. **Automatic Telemetry**: Spans automatically generate telemetry events when they end +4. **Memory Efficient**: Closure-based implementation reduces object overhead +5. **Cleaner API**: Only the necessary interfaces are exposed publicly + +## Files Modified + +- ✅ `AISKU/src/OpenTelemetry/trace/AppInsightsTraceProvider.ts` - Converted to factory function +- ✅ `AISKU/src/OpenTelemetry/trace/span.ts` - Inline implementation with callback support +- ✅ `AISKU/src/applicationinsights-web.ts` - Removed exports +- ✅ `AISKU/src/AISku.ts` - Added trace provider integration +- ✅ `shared/AppInsightsCore/src/*` - Previous IOTelSpan interface reversion (completed) + +## Status + +✅ **COMPLETED** - All requested changes have been implemented: +- AppInsightsTraceProvider class removed and replaced with factory function +- AppInsightsSpan class removed and implemented inline in createSpan factory +- createSpan factory function is internal-only and includes callback for telemetry +- AISKU internally sets up trace provider during initialization +-
