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
• 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
