# github-pr-release

[![](https://img.shields.io/npm/v/github-pr-release.svg)](https://www.npmjs.com/package/github-pr-release)

Create a release pull request using GitHub API. Inspired by [git-pr-release](https://github.com/motemen/git-pr-release).

- No dependency on git. You can easily deploy it to Heroku / AWS Lambda / Google Cloud Functions etc.
- Fast because it uses only Github API.
- Written in TypeScript / JavaScript.

## Usage

### API: release(config)

Create a release pull request and return Promise.

You must pass a config as an argument.

```javascript
const release = require("github-pr-release");

const config = {
token: "your github token",
owner: "uiur",
repo: "awesome-web-app",
head: "master", // optional
base: "production", // optional
template: "/path/to/template.mustache", // optional
};

release(config).then(function (pullRequest) {
// success
// `pullRequest` is an object that github api returns.
// See: https://developer.github.com/v3/pulls/#get-a-single-pull-request
});
```

Also, the following environment variables can be used for the config:

- `GITHUB_PR_RELEASE_OWNER`
- `GITHUB_PR_RELEASE_REPO`
- `GITHUB_PR_RELEASE_TOKEN`
- `GITHUB_PR_RELEASE_HEAD`
- `GITHUB_PR_RELEASE_BASE`
- `GITHUB_PR_RELEASE_ENDPOINT`

### CLI

You can create a release pull request by the following command:

```sh
❯ npx github-pr-release owner/repo --head master --base production
# `GITHUB_PR_RELEASE_TOKEN` is required
```

`--help`:

```
❯ npx github-pr-release --help
Usage: github-pr-release [repo]

Options:
--help Show help [boolean]
--version Show version number [boolean]
--head [default: "master"]
--base [default: "production"]

Examples:
github-pr-release uiur/github-pr-release --head master --base production
```

## Install

```
npm install github-pr-release
```

## Tips

### Pull request titles

If one of pull requests of which consist a release pull request has a title like "Bump to v1.0", the title of the release pull request becomes "Release v1.0". Otherwise, it uses timestamps like "Release 2000-01-01 00:00:00" in local timezone.

### Specify a message format

You can specify a template to change the message format. Pass a template path to `config.template`.

```javascript
release({
token: 'token'
owner: 'uiur',
repo: 'awesome-web-app',
template: './template.mustache'
})
```

The default template is below. The first line is treated as the title.

```mustache
Release {{version}}
{{#prs}}
- [ ] #{{number}} {{title}} {{#assignee}}@{{login}}{{/assignee}}{{^assignee}}{{#user}}@{{login}}{{/user}}{{/assignee}}
{{/prs}}
```

### GitHub Enterprise

If you use this plugin in GitHub Enterprise, you can specify endpoint domain for GitHub Enterprise.

```javascript
release({
token: 'token'
owner: 'uiur',
repo: 'awesome-web-app',
endpoint: 'https://github.yourdomain.com/api/v3'
})
```

## Example

### GitHub Actions

Creating release pull requests can be automated using GitHub Actions.

Create `.github/workflows/create-pr-release.yml` with the following content:

```yml
name: Create release pull requests

on:
push:
branches: [master]

jobs:
build:
runs-on: ubuntu-latest

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
with:
node-version: 16.x
cache: "yarn"

- run: yarn install
- name: Create release pull requests
run: |
npx github-pr-release $GITHUB_REPOSITORY --head master --base production
env:
GITHUB_PR_RELEASE_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```

```coffee
release = require('github-pr-release')
module.exports = (robot) ->
robot.respond /release/i, (msg) ->
release(config).then((pullRequest) ->
msg.send pullRequest.html_url
)
.catch((err) ->
msg.send("Create release PR failed: " + err.message)
)
```

## Development

The release flow of github-pr-release is managed with github-pr-release itself.

It creates a release pull request when merging a topic branch or pushing to the main branch.
The update can be published by merging a release pull request.
