# Create a GitHub Action Using TypeScript
# Setup Kit CLI

This action provides downloading and caching distribution of the requested Kit
CLI, and adding it to the PATH

Use this template to bootstrap the creation of a TypeScript action. :rocket:
## Usage

This template includes compilation support, tests, a validation workflow,
publishing, and versioning guidance.
See [action.yml](action.yml)

```YAML
- uses: setup-kit@v1
with:
# The version of Kit CLI to install. Defaults to `latest`
version: v0.1.1
# Used to pull kit CLI releases. Since there's a default, this is typically not needed to be suplied.
# When running this action on github.com, the default value is sufficient.
# When running on GHES, you can pass a personal access token
# for github.com to avoid rate limiting.
token: ''
```
If you are new, there's also a simpler introduction in the
[Hello world JavaScript action repository](https://github.com/actions/hello-world-javascript-action).
**Basic**
## Create Your Own Action
```YAML
steps:
- uses: setup-kit@v1
id: install_kit

- name: Run kit command
shell: bash
run: |
set -x
kit version
```
To create your own action, you can use this repository as a template! Just
follow the below instructions:
**Pin a kit version**
1. Click the **Use this template** button at the top of the repository
1. Select **Create a new repository**
1. Select an owner and name for your new repository
1. Click **Create repository**
1. Clone your new repository
```YAML
steps:
- uses: setup-kit@v1
id: install_kit
with:
version: v0.1.1

- name: Run kit command
shell: bash
run: |
set -x
kit version
```
## Initial Setup
### Supported version syntax
After you've cloned the repository to your local machine or codespace, you'll
need to perform some initial setup steps before you can develop your action.
The `version` input supports the Semantic Versioning Specification, for more
detailed examples please refer to
[the semver package documentation](https://github.com/npm/node-semver).

## Update the Action Metadata

The [`action.yml`](action.yml) file defines metadata about your action, such as
input(s) and output(s). For details about this file, see
[Metadata syntax for GitHub Actions](https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions).

When you copy this repository, update `action.yml` with the name, description,
inputs, and outputs for your action.

## Update the Action Code

The [`src/`](./src/) directory is the heart of your action! This contains the
source code that will be run when your action is invoked. You can replace the
contents of this directory with your own code.

There are a few things to keep in mind when writing your action code:

- Most GitHub Actions toolkit and CI/CD operations are processed asynchronously.
In `main.ts`, you will see that the action is run in an `async` function.

```javascript
import * as core from '@actions/core'
//...
async function run() {
try {
//...
} catch (error) {
core.setFailed(error.message)
}
}
```

For more information about the GitHub Actions toolkit, see the
[documentation](https://github.com/actions/toolkit/blob/master/README.md).

So, what are you waiting for? Go ahead and start customizing your action!

1. Create a new branch

```bash
git checkout -b releases/v1
```

1. Replace the contents of `src/` with your action code
1. Add tests to `__tests__/` for your source code
1. Format, test, and build the action

```bash
npm run all
```

> This step is important! It will run [`ncc`](https://github.com/vercel/ncc)
> to build the final JavaScript action code with all dependencies included.
> If you do not run this step, your action will not work correctly when it is
> used in a workflow. This step also includes the `--license` option for
> `ncc`, which will create a license file for all of the production node
> modules used in your project.

1. Commit your changes

```bash
git add .
git commit -m "My first action is ready!"
```

1. Push them to your repository

```bash
git push -u origin releases/v1
```

1. Create a pull request and get feedback on your action
1. Merge the pull request into the `main` branch

Your action is now published! :rocket:

For information about versioning your action, see
[Versioning](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md)
in the GitHub Actions toolkit.

## Validate the Action

You can now validate the action by referencing it in a workflow file. For
example, [`ci.yml`](./.github/workflows/ci.yml) demonstrates how to reference an
action in the same repository.

```yaml
steps:
- name: Checkout
id: checkout
uses: actions/checkout@v4
- name: Test Local Action
id: test-action
uses: ./
with:
milliseconds: 1000
- name: Print Output
id: output
run: echo "${{ steps.test-action.outputs.time }}"
```

For example workflow runs, check out the
[Actions tab](https://github.com/actions/typescript-action/actions)! :rocket:

## Usage

After testing, you can create version tag(s) that developers can use to
reference different stable versions of your action. For more information, see
[Versioning](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md)
in the GitHub Actions toolkit.

To include the action in a workflow in another repository, you can use the
`uses` syntax with the `@` symbol to reference a specific branch, tag, or commit
hash.

```yaml
steps:
- name: Checkout
id: checkout
uses: actions/checkout@v4
- name: Test Local Action
id: test-action
uses: actions/typescript-action@v1 # Commit with the `v1` tag
with:
milliseconds: 1000
- name: Print Output
id: output
run: echo "${{ steps.test-action.outputs.time }}"
```
