WalkthroughAdds a new URLEncoderDecoder React component implementing XOR-based obfuscation with Base64URL encode/decode, integrates it into DevTools, and updates DevArea routing/menu to the new path (/devarea/url-encoder-decoder). Includes UI controls, auto/manual conversion, copy/clear actions, and error handling. Changes

29-31: LGTM!The URL Encoder/Decoder tool configuration is correctly updated with the new route path and availability flag.
src/pages/DevArea/DevTools.jsx (1)
6-6: LGTM!The URLEncoderDecoder component is properly imported and registered in the tools mapping, consistent with the routing changes in index.jsx.
Also applies to: 15-15
src/components/DevAreaTools/URLEncoderDecoder.jsx (6)
29-46: LGTM!The conversion logic is properly memoized with
useCallback, includes correct error handling, and the dependency array[input, mode]is appropriate.
48-59: LGTM!The copy handler properly uses the Clipboard API, includes error handling with both console logging and user notification, and provides visual feedback via the
copiedstate.
61-64: LGTM!The clear handler correctly resets both input and output state.
66-70: LGTM!The effect correctly depends on
[input, mode, auto, handleConvert], ensuring auto-conversion triggers when any relevant state changes.
152-157: LGTM!The output textarea correctly uses
text-green-400onbg-gray-800, providing adequate color contrast and appropriate read-only styling.
186-192: LGTM!The security notice appropriately warns users that XOR obfuscation is not cryptographically secure and explicitly lists use cases to avoid (passwords, API keys, sensitive data).

Critical: XOR function breaks multi-byte Unicode characters.
The charCodeAt(0) approach only reads the first UTF-16 code unit, corrupting emoji, CJK characters, and other multi-byte Unicode. The PR objectives state "Replaces btoa/atob with Unicode-safe Base64 encoding/decoding using TextEncoder/TextDecoder to support emoji and CJK characters," but this implementation doesn't achieve that goal.
Replace with Unicode-safe XOR using TextEncoder/TextDecoder:
-const xorObfuscate = (text, key = 129) => {
- return text
- .split("")
- .map((c) => String.fromCharCode(c.charCodeAt(0) ^ key))
- .join("");
-};
+const xorObfuscate = (text, key = 129) => {
+ const encoder = new TextEncoder();
+ const bytes = encoder.encode(text);
+ const xored = new Uint8Array(bytes.length);
+ for (let i = 0; i < bytes.length; i++) {
+ xored[i] = bytes[i] ^ key;
+ }
+ const decoder = new TextDecoder();
+ return decoder.decode(xored);

In src/components/DevAreaTools/URLEncoderDecoder.jsx around lines 5 to 10, the
current xorObfuscate reads UTF-16 code units via charCodeAt(0) which corrupts
multi-byte Unicode (emoji, CJK). Replace it with a Unicode-safe implementation
that uses TextEncoder to convert the input string to a Uint8Array of bytes, XORs
each byte with the key (0-255), then uses TextDecoder to convert the resulting
byte array back to a string; ensure the function accepts a numeric key, bounds
it to a byte, and returns the decoded string.

Critical: btoa() doesn't support Unicode characters.
btoa() throws a "Character Out Of Range" error for multi-byte characters. The PR objectives explicitly mention replacing btoa with Unicode-safe encoding, but this code still uses it.

const toBase64Url = (str) => {

In src/components/DevAreaTools/URLEncoderDecoder.jsx around lines 12 to 14, the
toBase64Url function currently uses btoa which throws on Unicode/multi-byte
characters; replace it with a Unicode-safe implementation: use TextEncoder to
convert the input string to a Uint8Array, convert that byte array to a binary
string (e.g., by iterating bytes and mapping to String.fromCharCode), call btoa
on that binary string, then perform the Base64URL-safe replacements (replace '+'
with '-', '/' with '_', and strip trailing '='). Ensure this function works in
browsers (fallback to Buffer if running in a Node environment) and export/use
the new function in place of the old one.

Critical: atob() doesn't support Unicode characters.
atob() returns a binary string that must be decoded back to UTF-8. The current implementation doesn't handle this, breaking multi-byte characters.
Replace with Unicode-safe Base64URL decoding:
const fromBase64Url = (str) => {
str = str.replace(/-/g, "+").replace(/_/g, "/");
while (str.length % 4) str += "=";

In src/components/DevAreaTools/URLEncoderDecoder.jsx around lines 16 to 20, the
current fromBase64Url uses atob() directly which breaks multi-byte Unicode;
replace it with a Unicode-safe decode: convert URL-safe base64 to standard
base64 and pad, call atob to get the binary string, then percent-encode each
byte (e.g. build a string of '%'+byte.toString(16).padStart(2,'0') for each
charCode) and pass that to decodeURIComponent to obtain the correct UTF-8
string; also handle empty input/null safely.

Major accessibility issue: black text on dark background.
Line 136 sets text-black on bg-gray-800, creating insufficient color contrast. The PR objectives state "Improves color contrast (white on dark backgrounds) for accessibility," but this contradicts that goal.
Fix the text color for proper contrast:

In src/components/DevAreaTools/URLEncoderDecoder.jsx around lines 135 to 144,
the textarea has class "text-black" on a "bg-gray-800" background causing
insufficient contrast; replace the text color class with a light color (e.g.
text-white or text-gray-100) and, if needed, adjust the placeholder class to a
slightly lighter gray (e.g. placeholder-gray-400) to ensure readable contrast
while preserving existing padding/border/focus styles.
