actions

Committed GitHub Actions.

This is a mix of Typescript actions, composite actions and Dockerfile actions.

Usage

Use the latest branch for the version, unless you want to specific tagged version. For example use commitd/action/name@latest (where name is the directory in which the action is in this repository).

Development

This repository is based on actions/typescript-action which is a basic template and github/codeql-action which illustrates a multi-action repository (though is not a starter template).

We use the following branches:

• main the source
• latest the release branch. This contains the node_modules and build artifacts.

We have two different build processes:

• Running npm run package --action=<action_name> or npm run package:all will create a packaged ncc build which will be output to the dist/ directory. This is the artifact which are used by GitHub and in the tests.
• Running npm run build will perform a typescript build, which will be output to the build directory. This are not used, but the build is quicker.

The tests (npm test) can be considered (manual verified in most case) integration tests. Used the package built artifacts. As such you must build before you test:

npm run package:all
npm test

## Deployment

Deployment is automatic by pull request from main to latest. A GitHub Action will build the source (for all actions) and commit the new action code in dist to the latest branch.

It may be wise to tag a version if you are making breaking changes.

Use the v[yy.mm.dd] format for versioning. Hence a semantic release v1, v2, makes little sense as different components will have different breaking changes.

By this means user of the action can refer to the tag commitd/actions/[email protected] rather than commitd/actions/example@latest to pin to the version as of Feb 2020.

Adding a new Typescript action

Creating a new action with Typescript is simple by convention.

We assume the action is called example. Everywhere where example is included below you be replaced with the actual action name.

• Create a new directory in the root called example.
• Create an action.yml which should reference the script

# TODO: Give a good name and description
name: 'Committed Example'
description: 'An example github action'
author: 'Committed'
# TODO You may need inputs and outputs
runs:
  using: 'node12'
  # TODO: Replace this
  main: 'dist/example/index.js'

• Create a directory called example under src.
• Create an main.ts which will look like:

import * as core from "@actions/core"

async function run(): Promise<void> {
  try {
      // TODO Your code here
  } catch (error) {
    core.setFailed(error.message)
  }
}

run()

• Create a main.test.ts (though any name will do) which will run the compiled action

test("Run example", () => {
  runAsAction("example", {
    // TODO: if you have any variables
  })
})

• You can now implement you function. If you are building a complex function then spilt into smaller files which can be independently unit tested.
• (Build and) Test your script as GitHub will npm run test:action --action=example
• Add a .github/workflow/test-example.yml which will run your test within an GitHub Action (but in this repo). This isn't checking general formatting, etc but will it will specifically run your tests and then GitHub will run your action.

name: Test example

# Only run on pull requests and push to main when the
on:
  push:
    branches:
      - main
    paths:
       - .github/workflows/test-example.yml
       - src/example/**.ts
  pull_request:
    paths:
      - .github/workflows/test-example.yml
      - src/example/**.ts

env:
  ACTION: example

jobs:
  test-action:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2

      - name: Set up Node
        uses: actions/setup-node@v1
        with:
          node-version: "16"
          cache: "npm"

      - name: Install
        run: npm ci

      - name: Build
        run: npm run package --action=${env.ACTION}

      - name: Test
        run: npm test src/${env.ACTION}

      # TODO: Before you run your example you might need something to run it on
      # e.g. a node project.
      # Here you will need to setup that test environment.

      - name: Use action
        uses: ./${env.ACTION}
        # Include any inputs your action needs
        # with:
        #  value: "123"

When you create a PR the test-example.yml will be run.

If you push the built dist directory to a branch, for example cf-example-dist, then you will be able to test your action in other repositories using uses: commitd/actions/example@cf-example-dist.

Adding a new composite or Docker action

Composite and Docker action can be created simply:

• Create a new directory with the name of your action.
• Add the action.yml as specification
• Add the another files (e.g. Dockerfile)

This can then be pull-requested, etc as with a Typescript action.

Please note!

You must commit the node_modules directory and all the build artifacts.

This is a multi action repository, the actions are named by directory. Within an action directory there will is a action.yml file. To avoid confusion, limit the number of directories to a minimum!

You can use either branch or tag (or commit) to refer to which action you want. As we have multiple actions, we are versioning everything at once.

Tips

debug is only output if you set the secret ACTIONS_RUNNER_DEBUG to true
