C# - NuGet

Using NuGet lock files:

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

Depending on the environment, huge packages might be pre-installed in the global cache folder. If you do not want to include them, consider to move the cache folder like below.

Note: This workflow does not work for projects that require files to be placed in user profile package folder

env:
  NUGET_PACKAGES: ${{ github.workspace }}/.nuget/packages
steps:
  - uses: actions/cache@v1
    with:
      path: ${{ github.workspace }}/.nuget/packages
      key: ${{ runner.os }}-nuget-${{ hashFiles('**/packages.lock.json') }}
      restore-keys: |
        ${{ runner.os }}-nuget-        

Elixir - Mix

- 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

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

Java - Gradle

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

Java - Maven

- 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

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

Windows

- 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

- 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

The yarn cache directory will depend on your operating system and version of yarn. See https://yarnpkg.com/lang/en/docs/cli/cache/ for more info.

- name: Get yarn cache
  id: yarn-cache
  run: echo "::set-output name=dir::$(yarn cache dir)"

- uses: actions/cache@v1
  with:
    path: ${{ steps.yarn-cache.outputs.dir }}
    key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}
    restore-keys: |
      ${{ runner.os }}-yarn-      

PHP - Composer

- 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-      

Python - pip

For pip, the cache directory will vary by OS. See https://pip.pypa.io/en/stable/reference/pip_install/#caching

Locations:

• Ubuntu: ~/.cache/pip
• Windows: ~\AppData\Local\pip\Cache
• macOS: ~/Library/Caches/pip

Simple example

- uses: actions/cache@v1
  with:
    path: ~/.cache/pip
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
    restore-keys: |
      ${{ runner.os }}-pip-      

Replace ~/.cache/pip with the correct path if not using Ubuntu.

Multiple OS's in a workflow

- uses: actions/cache@v1
  if: startsWith(runner.os, 'Linux')
  with:
    path: ~/.cache/pip
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
    restore-keys: |
      ${{ runner.os }}-pip-      

- uses: actions/cache@v1
  if: startsWith(runner.os, 'macOS')
  with:
    path: ~/Library/Caches/pip
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
    restore-keys: |
      ${{ runner.os }}-pip-      

- uses: actions/cache@v1
  if: startsWith(runner.os, 'Windows')
  with:
    path: ~\AppData\Local\pip\Cache
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
    restore-keys: |
      ${{ runner.os }}-pip-      

Using a script to get cache location

Note: This uses an internal pip API and may not always work

- name: Get pip cache
   id: pip-cache
   run: |
     python -c "from pip._internal.locations import USER_CACHE_DIR; print('::set-output name=dir::' + USER_CACHE_DIR)"     

- uses: actions/cache@v1
  with:
    path: ${{ steps.pip-cache.outputs.dir }}
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
    restore-keys: |
      ${{ runner.os }}-pip-      

Ruby - Gem

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

When dependencies are installed later in the workflow, we must specify the same path for the bundler.

- name: Bundle install
  run: |
    bundle config path vendor/bundle
    bundle install --jobs 4 --retry 3    

Rust - Cargo

- 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

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

Swift, Objective-C - CocoaPods

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