⚠️ Work on this tool will continue at https://github.com/microsoft/typescript-analyze-trace
Tool for analyzing the output of tsc --generateTrace automatically, rather than following the steps here.
Note: The goal is to identify clear-cut hot-spots and provide enough context to extract a small repro. The repro can then be used as the basis of a bug report or a starting point for manual code inspection or profiling.
First, build your project with --generateTrace traceDir. Then, run npx ts-analyze-trace traceDir to see a sorted list of compilation hot-spots.
You can invoke analyze-trace directly to analyze a single trace (optionally, with types), rather than a whole directory.
You can use normalize-positions to convert file offsets to line-character pairs and skip past trivia (whitespace, comments, etc).
