## Creating an Action with the Toolkit
:question: [Choosing an action type](docs/action-types.md)
Outlines the differences and why you would want to create a JavaScript or a container based action.
:curly_loop: [Versioning](docs/action-versioning.md)
Actions are downloaded and run from the GitHub graph of repos. This contains guidance for versioning actions and safe releases.
:warning: [Problem Matchers](docs/problem-matchers.md)
Problem Matchers are a way to scan the output of actions for a specified regex pattern and surface that information prominently in the UI.
:warning: [Proxy Server Support](docs/proxy-support.md)
Self-hosted runners can be configured to run behind proxy servers.
Illustrates how to create a simple hello world javascript action.
```javascript
...
const nameToGreet = core.getInput('who-to-greet');
console.log(`Hello ${nameToGreet}!`);
...
```
Walkthrough and template for creating a JavaScript Action with tests, linting, workflow, publishing, and versioning.
```javascript
async function run() {
try {
const ms = core.getInput('milliseconds');
console.log(`Waiting ${ms} milliseconds ...`)
...
```
```javascript
PASS ./index.test.js
✓ throws invalid number
✓ wait 500 ms
✓ test runs
Test Suites: 1 passed, 1 total
Tests: 3 passed, 3 total
```
Walkthrough creating a TypeScript Action with compilation, tests, linting, workflow, publishing, and versioning.
```javascript
import * as core from '@actions/core';
async function run() {
try {
const ms = core.getInput('milliseconds');
console.log(`Waiting ${ms} milliseconds ...`)
...
```
```javascript
PASS ./index.test.js
✓ throws invalid number
✓ wait 500 ms
✓ test runs
Test Suites: 1 passed, 1 total
Tests: 3 passed, 3 total
```
Create an action that is delivered as a container and run with docker.
```docker
FROM alpine:3.10
COPY LICENSE README.md /
COPY entrypoint.sh /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]
```
Create an action that is delivered as a container which uses the toolkit. This example uses the GitHub context to construct an Octokit client.
```docker
FROM node:slim
COPY . .
RUN npm install --production
ENTRYPOINT ["node", "/lib/main.js"]
```
```javascript
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}`)
```
