The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under the hood for caching global packages data but requires less configuration settings. Supported package managers are `npm`, `yarn`, `pnpm` (v6.10+). The `cache` input is optional.
Caching is turned on by default when a `packageManager` field is detected in the `package.json` file and no `cache` input is provided. The `package-manager-cache` input provides control over this automatic caching behavior. By default, `package-manager-cache` is set to `true`, which enables caching when a valid package manager field is detected in the `package.json` file. To disable this automatic caching, set the `package-manager-cache` input to `false`.
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/setup-node@v5
with:
package-manager-cache: false
- run: npm ci
```
> If no valid `packageManager` field is detected in the `package.json` file, caching will remain disabled unless explicitly configured. For workflows with elevated privileges or access to sensitive information, we recommend disabling automatic caching by setting `package-manager-cache: false` when caching is not needed for secure operation.
The action defaults to search for the dependency file (`package-lock.json`, `npm-shrinkwrap.json` or `yarn.lock`) in the repository root, and uses its hash as a part of the cache key. Use `cache-dependency-path` for cases when multiple dependency files are used, or they are located in different subdirectories.
**Note:** The action does not cache `node_modules`

Caching for npm dependencies is automatically enabled when your `package.json` contains a `packageManager` field set to `npm` and no explicit cache input is provided.
This behavior is controlled by the `package-manager-cache` input, which defaults to `true`. To turn off automatic caching, set `package-manager-cache` to `false`.

## Caching packages data
The action follows [actions/cache](https://github.com/actions/cache/blob/main/examples.md#node---npm) guidelines, and caches global cache on the machine instead of `node_modules`, so cache can be reused between different Node.js versions.
**Caching yarn dependencies:**
Yarn caching handles both yarn versions: 1 or 2.
Yarn caching handles both Yarn Classic (v1) and Yarn Berry (v2, v3, v4+).
