It generates a salt for its cache based on the various packages that are +used when compiling the test files. + +`package-hash` can generate an appropriate hash based on the package location +(on disk) and the `package.json` file. This hash is salted with a hash +for the `package-hash` itself. + +`package-hash` can detect when the package-to-be-hashed is a Git repository. In +the AVA example this is useful when you're debugging one of the packages used to +compile the test files. You can clone it locally and use `npm link` so AVA can +find the clone. The hash will include the HEAD (`.git/HEAD`) and its +corresponding ref (e.g. `.git/refs/heads/master`), any packed refs +(`.git/packed-refs`), as well as the diff (`git diff`) for any non-committed +changes. This makes it really easy to test your changes without having to +explicitly clear the cache in the parent project. + +## Installation + +```console +$ npm install --save package-hash +``` + +## Usage + +```js +const packageHash = require('package-hash') + +// Asynchronously: +const hash = await packageHash(require.resolve('babel-core/package.json')) + +// Synchronously: +const hash = packageHash.sync(require.resolve('babel-core/package.json')) +``` + +`packageHash()` / `packageHash.sync()` must be called with a file path for an +existing `package.json` file. To get the path to an npm package it's easiest to +use `require.resolve('the-name/package.json')`. + +You can provide multiple paths: + +```js +const hash = await packageHash([ + require.resolve('babel-core/package.json'), + require.resolve('babel-preset-es2015/package.json') +]) +``` + +An optional salt value can also be provided: + +```js +const hash = await packageHash(require.resolve('babel-core/package.json'), 'salt value') +``` + +## API + +### `packageHash(paths, salt?)` + +`paths: string | string[]` ➜ can be a single file path, or an array of paths. + +`salt: Array | Buffer | Object | string` ➜ optional.
