This tool aims to trace the file load tree.
If you run
tsc --explainFiles
you get something like
src/file.ts
Imported via './file' from file 'src/other-file.ts'
src/other-file.ts
Imported via './other-file' from file 'src/main.ts'
It is hard to trace all root files that caused src/file to be loaded.
The goal is to have an output like
src/file.ts < src/other-file.ts < src/main.ts
So you can easily trace the root file
Run tsc --explainFiles and pipe the output through it
tsc --explainFiles | npx better-tsc-explain-files
Optionally you can provide a file path to output only this file
tsc --explainFiles | npx better-tsc-explain-files "src/file.ts"
It requires TypeScript compiler output in English!
