Creating an Action with the Toolkit
Outlines the differences and why you would want to create a JavaScript or a container based action.
Actions are downloaded and run from the GitHub graph of repos. This contains guidance for versioning actions and safe releases.
Hello World JavaScript Action
Illustrates how to create a simple hello world javascript action.
...
const nameToGreet = core.getInput('who-to-greet');
console.log(`Hello ${nameToGreet}!`);
...
JavaScript Action Walkthrough
Walkthrough and template for creating a JavaScript Action with tests, linting, workflow, publishing, and versioning.
async function run() {
try {
const ms = core.getInput('milliseconds');
console.log(`Waiting ${ms} milliseconds ...`)
...
PASS ./index.test.js
✓ throws invalid number
✓ wait 500 ms
✓ test runs
Test Suites: 1 passed, 1 total
Tests: 3 passed, 3 total
TypeScript Action Walkthrough
Walkthrough creating a TypeScript Action with compilation, tests, linting, workflow, publishing, and versioning.
import * as core from '@actions/core';
async function run() {
try {
const ms = core.getInput('milliseconds');
console.log(`Waiting ${ms} milliseconds ...`)
...
PASS ./index.test.js
✓ throws invalid number
✓ wait 500 ms
✓ test runs
Test Suites: 1 passed, 1 total
Tests: 3 passed, 3 total
Docker Action Walkthrough
Create an action that is delivered as a container and run with docker.
FROM alpine:3.10
COPY LICENSE README.md /
COPY entrypoint.sh /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]
Docker Action Walkthrough with Octokit
Create an action that is delivered as a container which uses the toolkit. This example uses the GitHub context to construct an Octokit client.
FROM node:slim
COPY . .
RUN npm install --production
ENTRYPOINT ["node", "/lib/main.js"]
const myInput = core.getInput('myInput');
core.debug(`Hello ${myInput} from inside a container`);
const context = github.context;
console.log(`We can even get context data, like the repo: ${context.repo.repo}`)
Recommendations on versioning, releases and tagging your action.
