## C# - NuGet
Using [NuGet lock files ](https://docs.microsoft.com/nuget/consume-packages/package-references-in-project-files#locking-dependencies ):
```yaml
- 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 ](https://github.com/actions/toolkit/tree/master/packages/glob#exclude-patterns )
```yaml
- 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
```yaml
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
```yaml
- uses: actions/cache@v2
with:
path: ~/.dub
key: ${{ runner.os }}-dub-${{ hashFiles('**/dub.json') }}
restore-keys: |
${{ runner.os }}-dub-
```
### Windows
```yaml
- uses: actions/cache@v2
with:
path: ~\AppData\Local\dub
key: ${{ runner.os }}-dub-${{ hashFiles('**/dub.json') }}
restore-keys: |
${{ runner.os }}-dub-
```
## Elixir - Mix
```yaml
- uses: actions/cache@v2
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@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.
```yaml
- 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 }}
```
## Haskell - Stack
```yaml
- uses: actions/cache@v2
name: Cache ~/.stack
with:
path: ~/.stack
key: ${{ runner.os }}-stack-global-${{ hashFiles('stack.yaml') }}-${{ hashFiles('package.yaml') }}
restore-keys: |
${{ runner.os }}-stack-global-
- uses: actions/cache@v2
name: Cache .stack-work
with:
path: .stack-work
key: ${{ runner.os }}-stack-work-${{ hashFiles('stack.yaml') }}-${{ hashFiles('package.yaml') }}-${{ hashFiles('**/*.hs') }}
restore-keys: |
${{ runner.os }}-stack-work-
```
## Java - Gradle
```yaml
- uses: actions/cache@v2
with:
path: ~/.gradle/caches
key: ${{ runner.os }}-gradle-${{ hashFiles('**/*.gradle*') }}
restore-keys: |
${{ runner.os }}-gradle-
```
## Java - Maven
```yaml
- 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 ](https://github.com/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
```yaml
- uses: actions/cache@v2
with:
path: ~/.npm
key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
restore-keys: |
${{ runner.os }}-node-
```
### Windows
```yaml
- name: Get npm cache directory
id: npm-cache
run: |
echo "::set-output name=dir::$(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: |
${{ runner.os }}-node-
```
### Using multiple systems and `npm config`
```yaml
- name: Get npm cache directory
id: npm-cache
run: |
echo "::set-output name=dir::$(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
```yaml
- 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.
```yaml
- 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.
```yaml
- name: Restore Cache
id: restore-cache
uses: actions/cache@v2
with:
path: _export
key: ${{ runner.os }}-esy-${{ hashFiles('esy.lock/index.json') }}
restore-keys: |
${{ runner.os }}-esy-
- name: Esy install
run: 'esy install'
- name: Import Cache
run: |
esy import-dependencies _export
rm -rf _export
...(Build job)...
# Re-export dependencies if anything has changed or if it is the first time
- name: Setting dependency cache
run: |
esy export-dependencies
if: steps.restore-cache.outputs.cache-hit != 'true'
```
## PHP - Composer
```yaml
- name: Get Composer Cache Directory
id: composer-cache
run: |
echo "::set-output name=dir::$(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
```yaml
- 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
```yaml
- 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: |
${{ runner.os }}-pip-
```
### Using pip to get cache location
> Note: This requires pip 20.1+
```yaml
- name: Get pip cache dir
id: pip-cache
run: |
echo "::set-output name=dir::$(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
```yaml
- 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
```yaml
- 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
```yaml
- 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
```yaml
- 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.
```yaml
- name: Bundle install
run: |
bundle config path vendor/bundle
bundle install --jobs 4 --retry 3
```
## Rust - Cargo
```yaml
- uses: actions/cache@v2
with:
path: |
~/.cargo/registry
~/.cargo/git
target
key: ${{ runner.os }}-cargo-${{ hashFiles('**/Cargo.lock') }}
```
## Scala - SBT
```yaml
- name: Cache SBT
uses: actions/cache@v2
with:
path: |
~/.ivy2/cache
~/.sbt
key: ${{ runner.os }}-sbt-${{ hashFiles('**/build.sbt') }}
```
## Swift, Objective-C - Carthage
```yaml
- uses: actions/cache@v2
with:
path: Carthage
key: ${{ runner.os }}-carthage-${{ hashFiles('**/Cartfile.resolved') }}
restore-keys: |
${{ runner.os }}-carthage-
```
## Swift, Objective-C - CocoaPods
```yaml
- uses: actions/cache@v2
with:
path: Pods
key: ${{ runner.os }}-pods-${{ hashFiles('**/Podfile.lock') }}
restore-keys: |
${{ runner.os }}-pods-
```
## Swift - Swift Package Manager
```yaml
- uses: actions/cache@v2
with:
path: .build
key: ${{ runner.os }}-spm-${{ hashFiles('**/Package.resolved') }}
restore-keys: |
${{ runner.os }}-spm-
```
