# project-utils (@-xun/project)

<!-- symbiote-template-region-end -->

`@-xun/project` is a library to help me wrangle the complex landscape between
monorepos and polyrepos.

It essentially unifies and re-exports the contents of three packages:

- [`@-xun/project-fs`][1] — utilities for parsing, interpreting, and
  transforming a project's files.
- [`@-xun/project-graph`][2] — utilities for deep structural analysis of
  projects and their dependencies.
- [`@-xun/project-types`][3] — powerful reflective project-related types.

Though not re-exported as part of the official package, this monorepo also
contains [`bidirectional-resolve`][4], which allows the [conditional][5] mapping
of [package entry points][6] into file paths (similar to `require.resolve`).
However, unlike prior art, `bidirectional-resolve` also allows the conditional
mapping of arbitrary file paths _back into package entry points_!

## Appendix

<!-- symbiote-template-region-end -->

Further documentation can be found under [`docs/`][x-repo-docs], and at each
sub-package's documentation directory.

### Published Package Details

This is a [CJS2 package][x-pkg-cjs-mojito] with statically-analyzable exports
built by Babel for use in Node.js versions that are not end-of-life. For
TypeScript users, this package supports both `"Node10"` and `"Node16"` module
resolution strategies.

<!-- symbiote-template-region-end -->
<!-- TODO: additional package details here -->
<!-- symbiote-template-region-start 7 -->

<details><summary>Expand details</summary>

That means both CJS2 (via `require(...)`) and ESM (via `import { ... } from ...`
or `await import(...)`) source will load this package from the same entry points
when using Node. This has several benefits, the foremost being: less code
shipped/smaller package size, avoiding [dual package
hazard][x-pkg-dual-package-hazard] entirely, distributables are not
packed/bundled/uglified, a drastically less complex build process, and CJS
consumers aren't shafted.

Each entry point (i.e. `ENTRY`) in [`package.json`'s
`exports[ENTRY]`][x-repo-package-json] object includes one or more [export
conditions][x-pkg-exports-conditions]. These entries may or may not include: an
[`exports[ENTRY].types`][x-pkg-exports-types-key] condition pointing to a type
declaration file for TypeScript and IDEs, a
[`exports[ENTRY].module`][x-pkg-exports-module-key] condition pointing to
(usually ESM) source for Webpack/Rollup, a `exports[ENTRY].node` and/or
`exports[ENTRY].default` condition pointing to (usually CJS2) source for Node.js
`require`/`import` and for browsers and other environments, and [other
conditions][x-pkg-exports-conditions] not enumerated here. Check the
[package.json][x-repo-package-json] file to see which export conditions are
supported.

Note that, regardless of the [`{ "type": "..." }`][x-pkg-type] specified in
[`package.json`][x-repo-package-json], any JavaScript files written in ESM
syntax (including distributables) will always have the `.mjs` extension. Note
also that [`package.json`][x-repo-package-json] may include the
[`sideEffects`][x-pkg-side-effects-key] key, which is almost always `false` for
optimal [tree shaking][x-pkg-tree-shaking] where appropriate.
