# cache
|
|
|
|
This GitHub Action allows caching dependencies and build outputs to improve workflow execution time.
|
|
|
|
## Usage
|
|
|
|
### Pre-requisites
|
|
Create a workflow `.yml` file in your repositories `.github/workflows` directory. An [example workflow](#example-workflow) is available below. For more information, reference the GitHub Help Documentation for [Creating a workflow file](https://help.github.com/en/articles/configuring-a-workflow#creating-a-workflow-file).
|
|
|
|
### Inputs
|
|
|
|
* `path` - A directory to store and save the cache
|
|
* `key` - An explicit key for restoring and saving the cache
|
|
* `restore-keys` - An ordered list of keys to use for restoring the cache if no cache hit occurred for key
|
|
|
|
### Outputs
|
|
|
|
* `cache-hit` - A boolean value to indicate an exact match was found for the key
|
|
|
|
> See [Skipping steps based on cache-hit](#Skipping-steps-based-on-cache-hit) for info on using this output
|
|
|
|
### Example workflow
|
|
|
|
```yaml
|
|
name: Example Caching with npm
|
|
|
|
on: push
|
|
|
|
jobs:
|
|
build:
|
|
runs-on: ubuntu-latest
|
|
|
|
steps:
|
|
- uses: actions/checkout@v1
|
|
|
|
- name: Cache node_modules
|
|
uses: actions/cache@preview
|
|
with:
|
|
path: node_modules
|
|
key: ${{ runner.os }}-node
|
|
|
|
- name: Install Dependencies
|
|
run: npm install
|
|
|
|
- name: Build
|
|
run: npm run build
|
|
|
|
- name: Test
|
|
run: npm run test
|
|
```
|
|
## Ecosystem Examples
|
|
|
|
### Node - npm
|
|
|
|
```yaml
|
|
- uses: actions/cache@preview
|
|
with:
|
|
path: node_modules
|
|
key: ${{ runner.os }}-node
|
|
```
|
|
|
|
### Node - Yarn
|
|
|
|
```yaml
|
|
- uses: actions/cache@preview
|
|
with:
|
|
path: ~/.cache/yarn
|
|
key: ${{ runner.os }}-yarn-${{ hashFiles(format('{0}{1}', github.workspace, '/yarn.lock')) }}
|
|
restore-keys: |
|
|
${{ runner.os }}-yarn-
|
|
```
|
|
|
|
### C# - Nuget
|
|
|
|
```yaml
|
|
- uses: actions/cache@preview
|
|
with:
|
|
path: ~/.nuget/packages
|
|
key: ${{ runner.os }}-nuget-${{ hashFiles('**/packages.lock.json') }}
|
|
restore-keys: |
|
|
${{ runner.os }}-nuget-
|
|
```
|
|
|
|
### Java - Gradle
|
|
|
|
```yaml
|
|
- uses: actions/cache@preview
|
|
with:
|
|
path: ~/.gradle/caches
|
|
key: gradle-${{ runner.os }}-${{ hashFiles('**/*.gradle') }}
|
|
restore-keys: |
|
|
gradle-${{ runner.os }}-
|
|
```
|
|
|
|
### Java - Maven
|
|
```yaml
|
|
- uses: actions/cache@preview
|
|
with:
|
|
path: ~/.m2/repository
|
|
key: ${{ runner.os }}-maven
|
|
```
|
|
|
|
## Cache Limits
|
|
|
|
Individual caches are limited to 200MB and a repository can have up to 2GB of caches. Once the 2GB limit is reached, older caches will be evicted based on when the cache was last accessed.
|
|
|
|
## Skipping steps based on cache-hit
|
|
|
|
Using the `cache-hit` output, subsequent steps (such as install or build) can be skipped when a cache hit occurs on the key.
|
|
|
|
Example:
|
|
```yaml
|
|
steps:
|
|
- uses: actions/checkout@v1
|
|
|
|
- uses: actions/cache@preview
|
|
id: cache
|
|
with:
|
|
path: path/to/dependencies
|
|
key: ${{ runner.os }}-${{ hashFiles('**/lockfiles')}}
|
|
|
|
- name: Install Dependencies
|
|
if: steps.cache.outputs.cache-hit != 'true'
|
|
run: /install.sh
|
|
```
|
|
|
|
> Note: The `id` defined in `actions/cache` must match the `id` in the `if` statement (i.e. `steps.[ID].outupts.cache-hit`)
