A utility to find and parse tsconfig files without depending on typescript

Because no simple official api exists and tsconfig isn't actual json.

• find closest tsconfig (tsconfig.json or jsconfig.json)
• convert tsconfig to actual json and parse it
• resolve "extends"
• resolve "references" of solution-style tsconfig
• resolve "${configDir}" variable
• optional caching for improved performance
• optional findNative and parseNative to use official typescript api
• zero dependencies (typescript optional)
• extensive testsuite
• completely async and optimized (it's fast)
• tiny 4.7KB gzip
• unbundled esm js, no sourcemaps needed
• types generated with dts-buddy

Used by vite*, vite-tsconfig-paths, astro and many more

(*) vite bundles tsconfck so it is listed as a devDependency

npm install --save-dev tsconfck # or pnpm, yarn

import { parse } from 'tsconfck';
const {
	tsconfigFile, // full path to found tsconfig
	tsconfig, // tsconfig object including merged values from extended configs
	extended, // separate unmerged results of all tsconfig files that contributed to tsconfig
	solution, // solution result if tsconfig is part of a solution
	referenced // referenced tsconfig results if tsconfig is a solution
} = await parse('foo/bar.ts');
