Q&A

Q1: What is this used for?

A1: It's used to obtain the file path for the NodeJS that comes with the Github Actions Runner.

Q2: What was the original intention behind creating this action?

A2: I wanted to write actions in Rust, compile them into WebAssembly (WASM), and then invoke them using NodeJS.

Unfortunately, not all systems come with NodeJS pre-installed.

Fortunately, we can use the NodeJS that comes with the Runner.

If it's your own machine, you can simply add the PATH.
However, if you're sharing actions with others, it's best not to make significant changes to the system environment.

The Runner that comes with NodeJS is located in the externals directory, such as /path/to/runners/externals/node20/bin/node.

Quick Start

Example 1

name: test
on: push

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - id: node_path
        uses: 2moe/node-path-action@v20
      - run: printf "${{steps.node_path.outputs.exe}}\n"

Example 2

name: test
on: push

jobs:
  test:
    runs-on: self-hosted
    steps:
      - id: node_path
        uses: 2moe/node-path-action@v20

      - name: Hello World
        shell: sh -e {0}
        run: |
          '${{steps.node_path.outputs.exe}}' <<'EOF'
            console.log("Hello world")
            throw Error("Panic")
          EOF

Tips:

To get the file path for NodeJS 16, change @v20 in 2moe/node-path-action@v20 to @v16

If you’re using Github Runners instead of self-hosted runners, you don’t need to use this action. You can directly use Node as a shell.

      - name: Hello World
        shell: node {0}
        run: console.log("Hello world")
