@alcalzone/release-script v3.7.0

release-script

Release script to automatically increment version numbers and push git tags. The features include:

• Bump the version in package.json (and package-lock.json)
• Update the changelog headline with the new version and release date whenever a release is made
• Add the changelog to the release commit and create a tag for it.
• ioBroker only:
  • Bump the version in io-package.json
  • Update the news in io-package.json and auto-translate the changelog to the other languages
  • Remove old news in order to stay under the limit of 20 entries.

Together with the corresponding Github Actions workflow (more on that below) this enables auto-publishing on npm and Github Releases if the build was successful.

Installation

1. Add this module to your devDependencies:

   npm i -D @alcalzone/release-script

2. Add a new npm script in package.json:

   "scripts": {
       ... other scripts ...
       "release": "release-script"
   }

3. Add a placeholder to README.md (for your own convenience)

   ## Changelog
   <!--
   	Placeholder for the next version (at the beginning of the line):
   	### **WORK IN PROGRESS**
   -->

   or CHANGELOG.md if you prefer to have a separate changelog (notice that there is one less #):

   # Changelog
   <!--
   	Placeholder for the next version (at the beginning of the line):
   	## **WORK IN PROGRESS**
   -->

4. If necessary (e.g. for custom versioning steps) use a config file

Usage

In order to use this script, you need to maintain the changelog in either README.md or CHANGELOG.md, because every release must have a changelog. To let the script know which changes are new, use the placeholder:

# Changelog
<!--
    Placeholder for the next version (at the beginning of the line):
    ## **WORK IN PROGRESS**
-->

## **WORK IN PROGRESS**
* Did some changes
* Did some more changes

## v0.0.1 (2020-01-01)
Initial release

Separate changelog for old entries

If you are using README.md, the script can automatically move old changelog entries to CHANGELOG_OLD.md if that exists. The most recent 5 entries are kept in README.md. To use this feature, simply create a CHANGELOG_OLD.md and give it a headline you like, e.g.

# Older changes

Add free text in the changelog entry headline

Starting with v1.8.0, you can add free text after the placeholder:

## **WORK IN PROGRESS** - 2020 Doomsday release

will be turned into

## 1.2.3 (2020-02-02) - 2020 Doomsday release

for example.

Command line

Once you are ready to release the changes, commit everything so the working tree is clean. Also make sure that you are on the master branch. Now you can create a release by executing:

npm run release [<releaseType> [<postfix>]] [-- [--dry] [--all]]

You can choose between the following release types: The available release types are:

For the pre* release types, you can optioinally provide a custom postfix, e.g. beta. For example, npm run release prepatch beta would result in the following bump: 0.9.8 -> 0.9.9-beta.0.

Test run

The release script makes it possible to test the command before actually changing anything. To do so, use the --dry argument. Take care to include the first set of hyphens (-- --dry) in the command or it won't be a dry run. Here's an example of a dry run that tells you what it would do and that it would fail due to uncommitted changes:

Include other changes in the release commit

Although the release commit should only include the changes relevant to the version increase, sometimes it makes sense to include other changes in the release commit. For this purpose, you can use the --all option, e.g.:

npm run release patch -- --all

Using a different remote than origin

If the remote you want to push to is not called origin, you can use the r flag to specify a different one (after the double dashes!)
Make sure to use the complete remote branch name:

npm run release patch -- -r upstream/master

lerna mode

If you are managing a monorepo with lerna, two additional options are available starting with v1.6.0. --lerna puts the release-script into lerna mode, which offloads all version increases to lerna. --lerna-check runs some checks regarding the changelog and then exits before doing any actual work. --lerna-check implies --lerna. For lerna mode to work, you need to configure lerna as follows

// lerna.json
{
	"version": "1.2.3", // must be fixed versioning, independent does not work!
	"command": {
		"version": {
			"amend": true // required, otherwise release-script cannot put the changelog into the commit body
		}
	}
}

and use the following package scripts:

// package.json
{
  // ...
  "scripts": {
    // ...
    "release": "lerna version",
    "preversion": "release-script --lerna-check",
    "version": "release-script --lerna",
    "postversion": "git push && git push --tags"
  }
}

Configuration with a config file

Instead of manually providing all options, you can configure the release process with a configuration file. By default, the script looks for a .releaseconfig.json in the current working directory. To change the filename, you can use the -c flag (after the double dashes!), e.g. release-script -- -c my-super-duper-config.json.

If an option is configured in this file, it will have precedence over CLI arguments. Here's a list of the supported options (they are all optional):

{
  "all": true, // Always include all changes in the release commit
  "lerna": true, // Enable lerna mode
  // Run custom scripts as part of the release process
  "scripts": {
    "beforePush": "npm run build", // runs after bumping the versions etc. but before pushing to git
  }
}

To execute multiple commands in sequence, you can also use an array of strings:

{
  "scripts": {
    "beforePush": [
      "echo 'this script is so cool'",
      "npm run build",
    ]
  }
}

Workflow file for automatic release

When using Github Actions, you can enable automatic release on npm and Github Releases after a tagged build was successful. To do so, include the following job in your workflow definition file (e.g. ./github/workflows/test-and-release.yml) and configure it to depend on the build jobs (here, they are called unit-tests). The workflow must be configured to run when tags are pushed.

Furthermore, you need to create a token in your npm account and add it to your repository secrets with the name NPM_TOKEN.

# Run this workflow on all pushes and pull requests
# as well as tags with a semantic version
on:
  push:
    # Configure your tested branches here, I like to check all of them. You can leave this out if you only want to deploy
    branches:
      - "*"
    # You MUST limit tags to ones that are compatible with the version scheme this script uses. DO NOT include any others or they will be released aswell
    tags:
      # normal versions
      - "v[0-9]+.[0-9]+.[0-9]+"
      # pre-releases
      - "v[0-9]+.[0-9]+.[0-9]+-**"
  # This runs the workflow for all pull requests. You can leave this out if you only want to deploy
  pull_request: {}

#
# ... your other jobs go here ...
#

  # Deploys the final package to NPM and Github Actions
  deploy:
    # Trigger this step only when a commit on master is tagged with a version number
    if: |
      contains(github.event.head_commit.message, '[skip ci]') == false &&
      github.event_name == 'push' &&
      github.event.base_ref == 'refs/heads/master' &&
      startsWith(github.ref, 'refs/tags/v')

    # Define which jobst must succeed before the release
    needs: [unit-tests]

    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [14.x]

    steps:
    - name: Checkout code
      uses: actions/checkout@v2

    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v1
      with:
        node-version: ${{ matrix.node-version }}

    - name: Extract the version and commit body from the tag
      # The body may be multiline, therefore we need to escape some characters
      run: |
        VERSION="${{ github.ref }}"
        VERSION=${VERSION##*/v}
        echo "::set-env name=VERSION::$VERSION"
        BODY=$(git show -s --format=%b)
        BODY="${BODY//'%'/'%25'}"
        BODY="${BODY//$'\n'/'%0A'}"
        BODY="${BODY//$'\r'/'%0D'}"
        echo "::set-env name=BODY::$BODY"

    # If you are using TypeScript, additional build steps might be necessary
    # Run them here, e.g.:
    # - name: Install dependencies
    #   run: npm ci
    # - name: Create a clean build
    #   run: npx gulp build

    - name: Publish package to npm
      run: |
        npm config set //registry.npmjs.org/:_authToken=${{ secrets.NPM_TOKEN }}
        npm whoami
        npm publish

      uses: actions/create-release@v1
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
