## C# - Nuget
Using [NuGet lock files](https://docs.microsoft.com/nuget/consume-packages/package-references-in-project-files#locking-dependencies):

```yaml
- uses: actions/cache@v1
  with:
    path: ~/.nuget/packages
    key: ${{ runner.os }}-nuget-${{ hashFiles('**/packages.lock.json') }}
    restore-keys: |
      ${{ runner.os }}-nuget-      
```

## Elixir - Mix
```yaml
- uses: actions/cache@v1
  with:
    path: deps
    key: ${{ runner.os }}-mix-${{ hashFiles(format('{0}{1}', github.workspace, '/mix.lock')) }}
    restore-keys: |
      ${{ runner.os }}-mix-      
```

## Go - Modules

```yaml
- uses: actions/cache@v1
  with:
    path: ~/go/pkg/mod
    key: ${{ runner.os }}-go-${{ hashFiles('**/go.sum') }}
    restore-keys: |
      ${{ runner.os }}-go-      
```

## Java - Gradle

```yaml
- uses: actions/cache@v1
  with:
    path: ~/.gradle/caches
    key: ${{ runner.os }}-gradle-${{ hashFiles('**/*.gradle') }}
    restore-keys: |
      ${{ runner.os }}-gradle-      
```

## Java - Maven

```yaml
- uses: actions/cache@v1
  with:
    path: ~/.m2/repository
    key: ${{ runner.os }}-maven-${{ hashFiles('**/pom.xml') }}
    restore-keys: |
      ${{ runner.os }}-maven-      
```

## Node - npm

For npm, cache files are stored in `~/.npm` on Posix, or `%AppData%/npm-cache` on Windows. See https://docs.npmjs.com/cli/cache#cache

>Note: It is not recommended to cache `node_modules`, as it can break across Node versions and won't work with `npm ci`

### macOS and Ubuntu

```yaml
- uses: actions/cache@v1
  with:
    path: ~/.npm
    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
    restore-keys: |
      ${{ runner.os }}-node-      
```

### Windows

```yaml
- uses: actions/cache@v1
  with:
    path: ~\AppData\Roaming\npm-cache
    key: ${{ runner.os }}-node-${{ hashFiles('**\package-lock.json') }}
    restore-keys: |
      ${{ runner.os }}-node-      
```

### Using multiple systems and `npm config`

```yaml  
- name: Get npm cache directory
  id: npm-cache
  run: |
    echo "::set-output name=dir::$(npm config get cache)"
- uses: actions/cache@v1
  with:
    path: ${{ steps.npm-cache.outputs.dir }}
    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
    restore-keys: |
      ${{ runner.os }}-node-
```

## Node - Yarn

```yaml
- uses: actions/cache@v1
  with:
    path: ~/.cache/yarn
    key: ${{ runner.os }}-yarn-${{ hashFiles(format('{0}{1}', github.workspace, '/yarn.lock')) }}
    restore-keys: |
      ${{ runner.os }}-yarn-
```

## PHP - Composer

```yaml  
- name: Get Composer Cache Directory
  id: composer-cache
  run: |
    echo "::set-output name=dir::$(composer config cache-files-dir)"
- uses: actions/cache@v1
  with:
    path: ${{ steps.composer-cache.outputs.dir }}
    key: ${{ runner.os }}-composer-${{ hashFiles('**/composer.lock') }}
    restore-keys: |
      ${{ runner.os }}-composer-
```

## Ruby - Gem

```yaml
- uses: actions/cache@v1
  with:
    path: vendor/bundle
    key: ${{ runner.os }}-gem-${{ hashFiles('**/Gemfile.lock') }}
    restore-keys: |
      ${{ runner.os }}-gem-
```

## Rust - Cargo

```yaml
- name: Cache cargo registry
  uses: actions/cache@v1
  with:
    path: ~/.cargo/registry
    key: ${{ runner.os }}-cargo-registry-${{ hashFiles('**/Cargo.lock') }}
- name: Cache cargo index
  uses: actions/cache@v1
  with:
    path: ~/.cargo/git
    key: ${{ runner.os }}-cargo-index-${{ hashFiles('**/Cargo.lock') }}
- name: Cache cargo build
  uses: actions/cache@v1
  with:
    path: target
    key: ${{ runner.os }}-cargo-build-target-${{ hashFiles('**/Cargo.lock') }}
```

## Swift, Objective-C - Carthage

```yaml
- uses: actions/cache@v1
  with:
    path: Carthage
    key: ${{ runner.os }}-carthage-${{ hashFiles('**/Cartfile.resolved') }}
    restore-keys: |
      ${{ runner.os }}-carthage-      
```

## Swift, Objective-C - CocoaPods

```yaml
- uses: actions/cache@v1
  with:
    path: Pods
    key: ${{ runner.os }}-pods-${{ hashFiles('**/Podfile.lock') }}
    restore-keys: |
      ${{ runner.os }}-pods-      
```
