⚡ Refactor dossier-compiler to use Array joins for string generation - #102
google-labs-jules[bot] wants to merge 1 commit into
Conversation
- Replaces `md += ...` loops with `md.push(...)` and `[].map().join()` in both JS and CJS variants of `extension/shared/dossier-compiler`. - Preserves the same formatting and logic, but significantly speeds up generation times on large dossiers by avoiding expensive string reallocation. - Covered by existing tests (`test-dossier-compiler.js`, `smoke-test.sh`, and `integration-test.sh`).

💡 What: Refactored the Markdown generation loops in
extension/shared/dossier-compiler.js(and.cjs) to use array pushing (md.push) and array mapping ([].map().join('')) instead of string concatenation (md +=).🎯 Why: String concatenation within loops can result in poor memory usage patterns and slower execution times due to intermediate allocations, particularly for large dossiers. Using arrays and joining at the end is a standard optimization technique for constructing large strings in JavaScript.
📊 Measured Improvement:
A baseline benchmark compiling a large 100,000-item mock dossier via
compileDossierToMarkdownand running 100,000 iterations ofcompileSingleAuditToMarkdownyielded the following times:compileDossierToMarkdown(Unoptimized vs Optimized):compileSingleAuditToMarkdown(Unoptimized vs Optimized):The refactored code has been run through the
