Development

Prerequisites

Install the dependencies

$ npm install

Build the typescript and package it for distribution

$ npm run build && npm run pack

Run the tests ✔️

$ npm run build && npm test

Update action.yml

The action.yml contains defines the inputs and output for your action.

Update the action.yml with description, inputs and outputs for your action.

See the documentation

Change the Code

Most toolkit and CI/CD operations involve async operations so the action is run in an async function.

import * as core from '@actions/core';
...

async function run() {
  try {
      ...
  }
  catch (error) {
    core.setFailed(error.message);
  }
}

run()

See the toolkit documentation for the various packages.

Publish to a distribution branch

Actions are run from GitHub repos so we will checkin the packed dist folder.

Then run ncc and push the results:

$ npm run pack
$ git add dist
$ git commit -a -m "prod dependencies"
$ git push origin releases/v1

Your action is now published! 🚀

See the versioning documentation

Validate

You can now validate the action by referencing ./ in a workflow in your repo (see test.yml])

- uses: ./
  name: Delete all deployments
  with:
    token: ${{github.token}}
    type: delete-all

See the actions tab for runs of this action! 🚀

Deploy

After testing you can create a v1 tag to reference the stable and latest V1 action
