With custom Go version

TinyGo needs Go and, by default, this action will use whatever version is available in the runner. If you want to control the Go version, you can use actions/setup-go before acifani/setup-tinygo

steps:
  - uses: actions/checkout@v5
  - uses: actions/setup-go@v6
    with:
      go-version: '1.25'
  - uses: acifani/setup-tinygo@v3
    with:
      tinygo-version: '0.40.1'

With custom Binaryen version

This action will install Binaryen which is needed for building WASM on Windows and macOS. You can customize the version with the dedicated input value

steps:
  - uses: actions/checkout@v5
  - uses: acifani/setup-tinygo@v3
    with:
      tinygo-version: '0.40.1'
      binaryen-version: '129'

Without Binaryen

If you don't need Binaryen, you can omit the installation

steps:
  - uses: actions/checkout@v5
  - uses: acifani/setup-tinygo@v3
    with:
      tinygo-version: '0.40.1'
      install-binaryen: 'false'
