Performance

Diagnosing Performance Issues​

  • Latest version for TypeScript, dependencies, editor, plugins and extensions.
  • Disable all editor extensions.
  • No other hogging resources.
  • Use strict compilation.

Fixing TypeScript performance problems:

tsc --listFilesOnly
tsc --explainFiles > explanations.md
tsc --extendedDiagnostics
tsc --generateTrace <output_dir>
node --max-old-space-size=8192 ./node_modules/.bin/tsc -b --extendedDiagnostics --generateTrace ./ts-trace
pnpm dlx analyze-trace ./ts-trace
