\n\n## Install\n\n```sh\nnpm install --save-dev @esbuild-kit/cjs-loader\n```\n\n## Usage\n\nPass `@esbuild-kit/cjs-loader` into the [`--require`](https://nodejs.org/api/cli.html#-r---require-module) flag\n```sh\nnode -r @esbuild-kit/cjs-loader ./file.js\n```\n\n### TypeScript configuration\nThe following properties are used from `tsconfig.json` in the working directory:\n- [`strict`](https://www.typescriptlang.org/tsconfig#strict): Whether to transform to strict mode\n- [`jsx`](https://esbuild.github.io/api/#jsx): Whether to transform JSX\n\t> **Warning:** When set to `preserve`, the JSX syntax will remain untransformed. To prevent Node.js from throwing a syntax error, chain another Node.js loader that can transform JSX to JS.\n- [`jsxFactory`](https://esbuild.github.io/api/#jsx-factory): How to transform JSX\n- [`jsxFragmentFactory`](https://esbuild.github.io/api/#jsx-fragment): How to transform JSX Fragments\n- [`jsxImportSource`](https://www.typescriptlang.org/tsconfig#jsxImportSource): Where to import JSX functions from\n- [`allowJs`](https://www.typescriptlang.org/tsconfig#allowJs): Whether to apply the tsconfig to JS files\n- [`paths`](https://www.typescriptlang.org/tsconfig#paths): For resolving aliases\n\n#### Custom `tsconfig.json` path\nBy default, `tsconfig.json` will be detected from the current working directory.\n\nTo set a custom path, use the `ESBK_TSCONFIG_PATH` environment variable:\n\n```sh\nESBK_TSCONFIG_PATH=./path/to/tsconfig.custom.json node -r @esbuild-kit/cjs-loader ./file.js\n```\n\n \n\n
\n\n### Cache\nModules transformations are cached in the system cache directory ([`TMPDIR`](https://en.wikipedia.org/wiki/TMPDIR)). Transforms are cached by content hash so duplicate dependencies are not re-transformed.\n\nSet environment variable `ESBK_DISABLE_CACHE` to a truthy value to disable the cache:\n\n```sh\nESBK_DISABLE_CACHE=1 node -r @esbuild-kit/cjs-loader ./file.js\n```\n\n## Related\n\n- [tsx](https://github.com/esbuild-kit/tsx) - Node.js runtime powered by esbuild using [`@esbuild-kit/cjs-loader`](https://github.com/esbuild-kit/cjs-loader) and [`@esbuild-kit/esm-loader`](https://github.com/esbuild-kit/esm-loader).\n\n- [@esbuild-kit/esm-loader](https://github.com/esbuild-kit/esm-loader) - TypeScript to ESM transpiler using the Node.js loader API.\n\n\n## Sponsors\n\n
