release-it

What is release-it?

release-it is a versatile command-line tool for automating versioning and package publishing. It simplifies the release process by handling version bumps, changelogs, Git tags, and publishing to npm and other platforms.

What are release-it's main functionalities?

Version Bumping

Automatically bumps the version of your project. In this example, it bumps the minor version.

release-it minor

Changelog Generation

Generates a changelog based on the commits since the last release.

release-it --changelog

Git Tagging

Creates a new Git tag for the release.

release-it --git.tag

NPM Publishing

Publishes the package to the npm registry.

release-it --npm.publish

Custom Hooks

Allows you to define custom hooks to run at various points in the release process.

{ "hooks": { "before:init": "echo 'This is a custom hook'" } }

Other packages similar to release-it

standard-version

standard-version is a tool for versioning and changelog generation based on conventional commits. It focuses on standardizing the release process and is less customizable compared to release-it.

semantic-release

semantic-release automates the versioning and package publishing process based on the commit history. It is highly configurable and integrates with CI/CD pipelines, making it more suitable for complex workflows compared to release-it.

lerna

lerna is a tool for managing JavaScript projects with multiple packages. It can handle versioning and publishing for monorepos, offering more advanced features for multi-package repositories compared to release-it.

Release It! 🚀

CLI release tool for Git repos and npm packages.

Release It! automates the tedious tasks of software releases:

• Execute build commands
• Bump version (in e.g. package.json)
• Generate changelog
• Git commit, tag, push
• Create release at GitHub
• Upload assets to GitHub release
• Publish to npm
• Manage pre-releases
• Push build artefacts to a separate repository or branch

Updating from v2 to v3 should be painless. See v3.0.0 release notes!

💾 Installation

Global

As a globally available CLI tool:

npm install --global release-it

Local

As a devDependency in your project:

npm install --save-dev release-it

Add this as a script to package.json:

{
  "name": "my-package",
  "version": "1.0.0".
  "scripts": {
    "release": "release-it"
  },
  "devDependencies": {
    "release-it": "^4.2.0"
  }
}

Now you can run npm run release from the command line.

▶️ Usage

Release a new patch (increments from e.g. 1.0.4 to 1.0.5):

release-it

Release a patch, minor, major, or specific version:

release-it minor
release-it 0.8.3

See manage pre-releases for versions like 1.0.0-beta.2 and npm install my-package@next.

You can also do a "dry run", which won't write/touch anything, but does output the commands it would execute, and show the interactivity:

release-it --dry-run

⚙️ Configuration

Out of the box, release-it has sane defaults, and plenty of options to configure it. Put the options to override in .release-it.json in the project root. Example:

{
  "src": {
    "tagName": "v%s"
  },
  "github": {
    "release": true
  }
}

• Only the settings to override need to be in .release-it.json. Everything else will fall back to the default configuration.
• You can use --config if you want to use another path for the local .release-it.json.

Any option can also be set on the command-line, and will have highest priority. Example:

release-it minor --src.tagName='v%s' --github.release

Boolean arguments can be negated by using the no- prefix:

release-it --no-npm.publish

🤖 Interactive vs. non-interactive mode

By default, release-it is interactive and allows you to confirm each task before execution:

On a Continuous Integration (CI) environment, or by using the -n option, this is fully automated. No prompts are shown and the configured tasks will be executed. This is demonstrated in the first animation above. An overview of the default tasks:

Task	Option	Default	Prompt	Default
Ready (confirm version)	N/A	N/A	-	Y
Show staged files	N/A	N/A	prompt.src.status	N
Git commit	src.commit	true	prompt.src.commit	Y
Git push	src.push	true	prompt.src.push	Y
Git tag	src.tag	true	prompt.src.tag	Y
GitHub release	github.release	false	prompt.src.release	Y
npm publish	npm.publish	true	prompt.src.publish	Y

The left columns are default options in non-interactive (or CI) mode.

The prompt.* options on the right in the table are used for the default answers in interactive mode. You can still change the answer to either Y or N as the questions show up (or cancel the process with Ctrl-c).

🔗 Command Hooks

The command hooks are executed from the root directory of the src or dist repository, respectively:

• src.beforeStartCommand
• buildCommand - before files are staged for commit
• src.afterReleaseCommand
• dist.beforeStageCommand - before files are staged in dist repo
• dist.afterReleaseCommand

All commands can use configuration variables (like template strings):

"buildCommand": "tar -czvf foo-${src.tagName}.tar.gz ",
"afterReleaseCommand": "echo Successfully released ${version} to ${dist.repo}."

📡 SSH keys & git remotes

The tool assumes you've configured your SSH key and Git remotes correctly. In short: you're fine if you can git push. Otherwise, the following GitHub help pages might be useful: SSH and Managing Remotes.

✏️ GitHub Release

See this project's releases page for an example.

To create GitHub releases:

• The github.release option must be true.
• Obtain a GitHub access token.
• Make this available as the environment variable defined with github.tokenRef. Example:

export GITHUB_TOKEN="f941e0..."

📦 Release Assets

To upload binary release assets with a GitHub release (such as compiled executables, minified scripts, documentation), provide one or more glob patterns for the github.assets option. After the release, the assets are available to download from the GitHub release page. Example:

"github": {
  "release": true,
  "assets": "dist/*.zip"
}

🐣 Manage Pre-releases

With release-it, it's easy to create pre-releases: a version of your software that you want to make available, while it's not in the stable semver range yet. Often "alpha", "beta", and "rc" (release candidate) are used as identifier for pre-releases.

For example, if you're working on a new major update for awesome-pkg (while the latest release was v1.4.1), and you want others to try a beta version of it:

release-it major --preRelease=beta

This will tag and release version 2.0.0-beta.0. This is actually a shortcut for:

release-it premajor --preReleaseId=beta --npm.tag=beta --github.preRelease

Consecutive beta releases (v2.0.0-beta.1 and so on) are now easy:

release-it --preRelease=beta

Installing the package with npm:

npm install awesome-pkg         # Installs v1.4.1
npm install awesome-pkg@beta    # Installs v2.0.0-beta.1

You can still override e.g. the npm tag being used:

release-it --preRelease=rc --npm.tag=next

See semver.org for more details.

🚚 Distribution Repository

Some projects use a distribution repository. Reasons to do this include:

• Distribute to target specific package managers.
• Distribute to a Github Pages branch (also see Using GitHub Pages, the easy way).

Overall, it comes down to a need to release generated files (such as compiled bundles, documentation) into a separate repository. Some examples include:

• Projects like Ember, Modernizr and Bootstrap are in separate shim repositories.
• AngularJS maintains a separate packaged angular repository for distribution on npm and Bower.

To use this feature, set the dist.repo option to a git endpoint. This can be a branch (also of the same source repository), like "[e-mail]:webpro/release-it.git#gh-pages". Example:

"dist": {
  "repo": "[e-mail]:components/ember.git"
}

The repository will be cloned to dist.stageDir, and the dist.files (relative to dist.baseDir) will be copied from the source repository. The files will then be staged, commited and pushed back to the remote distribution repository.

Make sure to set dist.github.release and dist.npm.publish to true as needed. The dist.github.* options will use the github.* values as defaults. Idem dito for dist.npm.* options, using npm.* for default values.

During the release of a source and distribution repository, some "dist" tasks are executed before something is committed to the source repo. This is to make sure you find out about errors (e.g. while cloning or copying files) as soon as possible, and not after a release for the source repository first.

📝 Notes

• The "private": true setting in package.json will be respected and the package won't be published to npm.
• You can use src.pushRepo option to set an alternative url or name of a remote as in git push <src.pushRepo>. By default this is null and git push is used when pushing to the remote.

Examples

• π.simloovoo.com - Uses GitHub releases with attachments and various command hooks to run npm scripts.
• swagger-ui-cornify - Attaches minified release copies to GitHub releases
• React Truncate Markup
