Action Golang with cache

Composite GitHub Action which combines the perfect pairing of actions/setup-go with actions/cache for the caching of both the Golang module and build caches.

nuts and gum

Reducing all these workflow steps:

steps:
  - name: Setup Golang
    uses: actions/setup-go@v3
    with:
      go-version: ~1.17
  - name: Setup Golang caches
    uses: actions/cache@v3
    with:
      path: |
        ~/.cache/go-build
        ~/go/pkg/mod
      key: ${{ runner.os }}-golang-${{ hashFiles('**/go.sum') }}
      restore-keys: |
        ${{ runner.os }}-golang-

down to this:

steps:
  - name: Setup Golang with cache
    uses: magnetikonline/action-golang-cache@v2
    with:
      go-version: ~1.17

Action correctly sets the build and module cache paths for Linux, macOS and Windows runners as per the Golang cache examples.

In addition an optional cache-key-suffix input can be used to control the generated cache key - handy where a Golang program is compiled multiple times for different binaries across multiple workflow definitions - resulting in different optimized build cache path contents:

steps:
  - name: Testing action
    uses: magnetikonline/action-golang-cache@v2
    with:
      go-version: ~1.17
      cache-key-suffix: -apples

# cache key:   ${{ runner.os }}-golang-apples-${{ hashFiles('**/go.sum') }}
# restore key: ${{ runner.os }}-golang-apples-
