From 50c09f4eeeb6feb3d5e5affa1d044a046143bce3 Mon Sep 17 00:00:00 2001 From: Saurabh Misra Date: Sat, 31 Jan 2026 18:45:32 +0000 Subject: [PATCH 1/5] feat: Add find references functionality for JavaScript/TypeScript Implements a "find references" feature for JavaScript/TypeScript using tree-sitter, similar to Jedi's find_references for Python. This helps the optimizer and explanation generator understand which functions are calling the function being optimized. Key features: - Finds all call sites of a function across multiple files - Handles various import patterns: named, default, namespace, re-exports, aliases - Supports both ES modules and CommonJS - Handles memoized functions, callbacks, and method calls - Follows re-export chains to find references through barrel files - Tracks caller function context for each reference Includes 35 comprehensive unit tests covering real-world patterns from Appsmith: - Named exports and imports - Default exports with different import names - Re-exports and barrel files - Callback patterns (map, filter, reduce) - Import aliases - Namespace imports - Memoized functions (micro-memoize) - Same-file references (recursive calls) - Redux Saga patterns (yield call) - Redux Selector patterns (createSelector) - CommonJS require patterns Co-Authored-By: Claude Opus 4.5 --- .../languages/javascript/find_references.py | 852 ++++++++++++ tests/test_languages/test_find_references.py | 1152 +++++++++++++++++ 2 files changed, 2004 insertions(+) create mode 100644 codeflash/languages/javascript/find_references.py create mode 100644 tests/test_languages/test_find_references.py diff --git a/codeflash/languages/javascript/find_references.py b/codeflash/languages/javascript/find_references.py new file mode 100644 index 000000000..d9ed4792a --- /dev/null +++ b/codeflash/languages/javascript/find_references.py @@ -0,0 +1,852 @@ +"""Find references for JavaScript/TypeScript functions. + +This module provides functionality to find all references (call sites) of a function +across a JavaScript/TypeScript codebase.
