## Install

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

To install:

```shell
npm install @-xun/common-dummies
```

## Usage

When using `@-xun/common-dummies/repositories`, you must initialize the dummies
before use. This can be done via either an `npm prepare` script (i.e.
`node --no-warnings -e "import('@-xun/common-dummies/post-install')"`) or a
symbiote post-npm-install script (i.e.
`import '@-xun/common-dummies/post-install'`).

> [!TIP]
>
> If you're seeing errors like:
>
> ```text
> Cannot find module '/my/project/node_modules/@-xun/common-dummies/dist/...'
> from 'node_modules/@-xun/common-dummies/dist/packages/common-dummies/src/...'
> ```
>
> This is because you have not initialized the dummies before use.

Additionally, depending on your environment, it may be necessary to configure
[jest-haste-map][1] (via [`modulePathIgnorePatterns`][2]) to ignore the
directory containing the dummies.

### 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.
