C# - NuGet

Using NuGet lock files:

- uses: actions/cache@v2
  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. With actions/cache@v2 you can now exclude unwanted packages with exclude pattern

- uses: actions/cache@v2
  with:
    path: | 
      ~/.nuget/packages
      !~/.nuget/packages/unwanted
    key: ${{ runner.os }}-nuget-${{ hashFiles('**/packages.lock.json') }}
    restore-keys: |
      ${{ runner.os }}-nuget-      

Or you could 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@v2
    with:
      path: ${{ github.workspace }}/.nuget/packages
      key: ${{ runner.os }}-nuget-${{ hashFiles('**/packages.lock.json') }}
      restore-keys: |
        ${{ runner.os }}-nuget-        

D - DUB

POSIX

- uses: actions/cache@v2
  with:
    path: ~/.dub
    key: ${{ runner.os }}-dub-${{ hashFiles('**/dub.json') }}
    restore-keys: |
      ${{ runner.os }}-dub-      

Windows

- uses: actions/cache@v2
  with:
    path: ~\AppData\Local\dub
    key: ${{ runner.os }}-dub-${{ hashFiles('**/dub.json') }}
    restore-keys: |
      ${{ runner.os }}-dub-      

Elixir - Mix

- uses: actions/cache@v2
  with:
    path: deps
    key: ${{ runner.os }}-mix-${{ hashFiles(format('{0}{1}', github.workspace, '/mix.lock')) }}
    restore-keys: |
      ${{ runner.os }}-mix-      

Erlang - Rebar3

- uses: actions/cache@v2
  with:
    path: |
      ~/.cache/rebar3
      _build      
    key: ${{ runner.os }}-erlang-${{ env.OTP_VERSION }}-${{ hashFiles('**/*rebar.lock') }}
    restore-keys: |
      ${{ runner.os }}-erlang-${{ env.OTP_VERSION }}-      

Go - Modules

- uses: actions/cache@v2
  with:
    path: ~/go/pkg/mod
    key: ${{ runner.os }}-go-${{ hashFiles('**/go.sum') }}
    restore-keys: |
      ${{ runner.os }}-go-      

Haskell - Cabal

We cache the elements of the Cabal store separately, as the entirety of ~/.cabal can grow very large for projects with many dependencies.

- name: Cache ~/.cabal/packages, ~/.cabal/store and dist-newstyle
  uses: actions/cache@v2
  with:
    path: |
      ~/.cabal/packages
      ~/.cabal/store
      dist-newstyle      
    key: ${{ runner.os }}-${{ matrix.ghc }}

Java - Gradle

- uses: actions/cache@v2
  with:
    path: ~/.gradle/caches
    key: ${{ runner.os }}-gradle-${{ hashFiles('**/*.gradle*') }}
    restore-keys: |
      ${{ runner.os }}-gradle-      

Java - Maven

- name: Cache local Maven repository
  uses: actions/cache@v2
  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

If using npm config to retrieve the cache directory, ensure you run actions/setup-node first to ensure your npm version is correct.

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@v2
  with:
    path: ~/.npm
    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
    restore-keys: |
      ${{ runner.os }}-node-      

Windows

- name: Get npm cache directory
  id: npm-cache
  run: |
    echo "::set-output name=dir::$(npm config get cache)"    
- uses: actions/cache@v2
  with:
    path: ${{ steps.npm-cache.outputs.dir }}
    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@v2
  with:
    path: ${{ steps.npm-cache.outputs.dir }}
    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
    restore-keys: |
      ${{ runner.os }}-node-      

Node - Lerna

- name: restore lerna
  uses: actions/cache@v2
  with:
    path: |
      node_modules
      */*/node_modules      
    key: ${{ runner.os }}-${{ hashFiles('**/yarn.lock') }}

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

- uses: actions/cache@v2
  id: yarn-cache # use this to check for `cache-hit` (`steps.yarn-cache.outputs.cache-hit != 'true'`)
  with:
    path: ${{ steps.yarn-cache-dir-path.outputs.dir }}
    key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}
    restore-keys: |
      ${{ runner.os }}-yarn-      

OCaml/Reason - esy

Esy allows you to export built dependencies and import pre-built dependencies.

    - name: Restore Cache
      id: restore-cache
      uses: actions/cache@v2
      with:
        path: _export
        key:  ${{ runner.os }}-esy-${{ hashFiles('esy.lock/index.json') }}
        restore-keys: |
          ${{ runner.os }}-esy-          
    - name: Esy install
      run: 'esy install'
    - name: Import Cache
      run: |
        esy import-dependencies _export
        rm -rf _export        

    ...(Build job)...

    # Re-export dependencies if anything has changed or if it is the first time
    - name: Setting dependency cache 
      run: |
        esy export-dependencies        
      if: steps.restore-cache.outputs.cache-hit != 'true'

PHP - Composer

- name: Get Composer Cache Directory
  id: composer-cache
  run: |
    echo "::set-output name=dir::$(composer config cache-files-dir)"    
- uses: actions/cache@v2
  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@v2
  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@v2
  if: startsWith(runner.os, 'Linux')
  with:
    path: ~/.cache/pip
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
    restore-keys: |
      ${{ runner.os }}-pip-      

- uses: actions/cache@v2
  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@v2
  if: startsWith(runner.os, 'Windows')
  with:
    path: ~\AppData\Local\pip\Cache
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
    restore-keys: |
      ${{ runner.os }}-pip-      

Using pip to get cache location

Note: This requires pip 20.1+

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

- name: pip cache
  uses: actions/cache@v2
  with:
    path: ${{ steps.pip-cache.outputs.dir }}
    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 dir
 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@v2
  with:
    path: ${{ steps.pip-cache.outputs.dir }}
    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
    restore-keys: |
      ${{ runner.os }}-pip-      

R - renv

For renv, the cache directory will vary by OS. Look at https://rstudio.github.io/renv/articles/renv.html#cache

Locations:

• Ubuntu: ~/.local/share/renv
• macOS: ~/Library/Application Support/renv
• Windows: %LOCALAPPDATA%/renv

Simple example

- uses: actions/cache@v2
  with:
    path: ~/.local/share/renv
    key: ${{ runner.os }}-renv-${{ hashFiles('**/renv.lock') }}
    restore-keys: |
      ${{ runner.os }}-renv-      

Replace ~/.local/share/renv with the correct path if not using Ubuntu.

Multiple OS's in a workflow

- uses: actions/cache@v2
  if: startsWith(runner.os, 'Linux')
  with:
    path: ~/.local/share/renv
    key: ${{ runner.os }}-renv-${{ hashFiles('**/renv.lock') }}
    restore-keys: |
      ${{ runner.os }}-renv-      

- uses: actions/cache@v2
  if: startsWith(runner.os, 'macOS')
  with:
    path: ~/Library/Application Support/renv
    key: ${{ runner.os }}-renv-${{ hashFiles('**/renv.lock') }}
    restore-keys: |
      ${{ runner.os }}-renv-      

- uses: actions/cache@v2
  if: startsWith(runner.os, 'Windows')
  with:
    path: ~\AppData\Local\renv
    key: ${{ runner.os }}-renv-${{ hashFiles('**/renv.lock') }}
    restore-keys: |
      ${{ runner.os }}-renv-      

Ruby - Bundler

- uses: actions/cache@v2
  with:
    path: vendor/bundle
    key: ${{ runner.os }}-gems-${{ hashFiles('**/Gemfile.lock') }}
    restore-keys: |
      ${{ runner.os }}-gems-      

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
