github-pr-release

Create a release pull request using GitHub API. Inspired by 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 JavaScript.

Usage

<<<<<<< HEAD

release(config)

=======

API: release(config)

origin/master

Create a release pull request and return Promise.

You must pass a config as an argument.

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:

❯ 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"]

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.

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.

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.

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:

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 }}

hubot

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.
