GitHub Actions reusable workflow to generate prebuilds for a Node native add-on.

This workflow can be used to generate Node 18 - 26 prebuilds for Linux, macOS and Windows. The prebuilds will be stored in the prebuilds folder which should be added to .gitignore, and can be loaded using node-gyp-build with require('node-gyp-build')(__dirname).

NOTE: Currently, node-gyp-build must be <4 to work with this action.

Example usage with the available options and the defaults:

jobs:
  build:
    uses: Datadog/action-prebuildify/.github/workflows/build.yml@main
    with:
      artifact-name: '' # artifact to download into a same-named directory before building
      cache: false # enable caching of dependencies based on lockfile
      directory-path: '.' # The path to the directory containing your build files, relative to the repo root.
      min-node-version: 18 # The minimum Node.js version to build and test
      nightly-version: '' # Optional Node nightly version to prebuild for GYP/V8-native add-ons.
      napi: false # generate single Node-API binary for all versions of Node
      napi-rs: false # Whether or not this build is for a napi-rs project.
      neon: false # Whether or not this build is for a Neon project.
      package-manager: 'npm' # npm or yarn
      postbuild: '' # command to run after prebuilds have been generated
      prebuild: '' # command to run before prebuilds are generated
      rust: false # Whether or not this build is for a Rust project.
      skip: '' # list of jobs to skip, for example when a platform is not supported
      target-name: 'addon' # target name in binding.gyp (or napi.name in package.json for napi-rs projects)

Set nightly-version to manually add one Node nightly build target for testing. This is intended for downstream GYP/V8-native add-ons that may break when Node updates V8 or changes the Node ABI. It should be used as an opt-in compatibility check, not as part of the regular release prebuild workflow.

Use latest to build against the latest published Node nightly with headers:

with:
  nightly-version: latest

Use an explicit value when you need a specific nightly version or ABI:

with:
  nightly-version: v27.0.0-nightly20260623,150,~3.17

The explicit format is:

nodeVersion,abiVersion,alpineVersion

When nightly-version is set, the action fetches Node headers from https://nodejs.org/download/nightly and produces an additional ABI-specific prebuild, for example node-150.node.

This option does not add extra builds for napi, napi-rs, neon, or rust workflows. Those modes produce a Node-API-oriented artifact and are not expected to need a separate V8 ABI prebuild for each Node nightly.
