wasm-opt GitHub action

This docker action allows usage of binaryen's wasm-opt to optimize Wasm files inside your GitHub workflows. Binaryen is available under its Apache 2.0 License.

Usage

      # Optimize a single wasm file with options
      - name: Optimize file.wasm
        uses: JohannesDeml/binaryen-wasm-opt@v1
        with:
          file: some/path/to/file.wasm
          output: some/path/to/file.wasm
          options: --enable-bulk-memory --enable-threads
          binaryen_version: 122

      # Optimize all wasm files in the dist folder
      - name: Optimize all .wasm files
        uses: JohannesDeml/binaryen-wasm-opt@v1
        with:
          file: dist/*.wasm
          optimize_all: true

file [Required] input name, supports Unix shell like patterns. By default, only the first match is optimized.
optimize_all [Optional] Optimize all files matching the pattern, defaults to false.
output [Optional] output name, defaults to the original file path. This is very useful if you pass a glob as file.
binaryen_version [Optional] binaryen version used, defaults to 122 (All Versions).
options [Optional] options passed to wasm-opt, defaults to -Os. See also wasm-opt options

The input parameters are passed to wasm-opt like so: <input> -o <output> <options>.

For more examples (e.g. for godot wasm files) see ci.yaml.

Improvements added in the fork

Added support for selecting any Binaryen version
Action now fails if wasm-opt returns a non-zero exit code
Updated library versions (e.g rust) to make docker builds faster
Added CI pipeline for building and pushing docker images
