Standard Version

stop using npm version, use standard-version it rocks!

Automatic versioning and CHANGELOG management, using GitHub's new squash button and the recommended workflow for conventional-changelog.

how it works:

1. when you land commits on your master branch, select the Squash and Merge option.
2. add a title and body that follows the conventional-changelog-standard conventions.
3. when you're ready to release to npm:
4. git checkout master; git pull origin master
5. run standard-version
6. git push --follow-tags origin master; npm publish

standard-version does the following:

1. bumps the version in package.json (based on your commit history)
2. uses conventional-changelog to update CHANGELOG.md
3. commits package.json and CHANGELOG.md
4. tags a new release

Installation

As npm run script

Install and add to devDependencies:

npm i --save-dev standard-version

Add an npm run script to your package.json:

{
  "scripts": {
    "release": "standard-version"
  }
}

Now you can use npm run release in place of npm version.

This has the benefit of making your repo/package more portable, so that other developers can cut releases without having to globally install standard-version on their machine.

As global bin

Install globally (add to your PATH):

npm i -g standard-version

Now you can use standard-version in place of npm version.

This has the benefit of allowing you to use standard-version on any repo/package without adding a dev dependency to each one.

CLI Usage

First Release

To generate your changelog for your first release, simply do:

# npm run script
npm run release -- --first-release
# or global bin
standard-version --first-release

This will tag a release without bumping the version in package.json.

When ready, push the git tag and npm publish your first release. \o/

Cut a Release

If you typically use npm version to cut a new release, do this instead:

# npm run script
npm run release
# or global bin
standard-version

As long as your git commit messages are conventional and accurate, you no longer need to specify the semver type - and you get CHANGELOG generation for free! \o/

After you cut a release, you can push the new git tag and npm publish (or npm publish --tag next) when you're ready.

Prevent Git Hooks

If you use git hooks, like pre-commit, to test your code before committing, you can prevent hooks from being verified during the commit step by passing the --no-verify option:

# npm run script
npm run release -- --no-verify
# or global bin
standard-version --no-verify

Signing commits and tags

If you have your GPG key set up, add the --sign or -s flag to your standard-version command.

Committing generated artifacts in the release commit

If you want to commit generated artifacts in the release commit (e.g. #96), you can use the --commit-all or -a flag. You will need to stage the artifacts you want to commit, so your release command could look like this:

"prerelease": "webpack -p --bail",
"release": "git add <file(s) to commit> && standard-version -a"

CLI Help

# npm run script
npm run release -- --help
# or global bin
standard-version --help

Code usage

Use the silent option to stop standard-version from printing anything to the console.

var standardVersion = require('standard-version')

// Options are the same as command line, except camelCase
standardVersion({
  noVerify: true,
  infile: 'docs/CHANGELOG.md',
  silent: true
}, function (err) {
  if (err) {
    console.error(`standard-version failed with message: ${err.message}`)
  }
  // standard-version is done
})

Commit Message Convention, at a Glance

patches:

git commit -a -m "fix(parsing): fixed a bug in our parser"

features:

git commit -a -m "feat(parser): we now have a parser \o/"

breaking changes:

git commit -a -m "feat(new-parser): introduces a new parsing library
BREAKING CHANGE: new library does not support foo-construct"

other changes:

You decide, e.g., docs, chore, etc.

git commit -a -m "docs: fixed up the docs a bit"

but wait, there's more!

Github usernames (@bcoe) and issue references (#133) will be swapped out for the appropriate URLs in your CHANGELOG.

FAQ

How is standard-version different from semantic-release?

semantic-release is a fully automated library/system for versioning, changelog generation, git tagging, and publishing to the npm registry.

standard-version is different because it handles the versioning, changelog generation, and git tagging for you without automatic pushing (to GitHub) or publishing (to an npm registry). Use of standard-version only affects your local git repo - it doesn't affect remote resources at all. After you run standard-version, you still have to ability to review things and correct mistakes if you want to.

They are both based on the same foundation of structured commit messages (using Angular format), but standard-version is a good choice for folks who are not yet comfortable letting publishes go out automatically. In this way, you can view standard-version as an incremental step to adopting semantic-release.

We think they are both fantastic tools, and we encourage folks to use semantic-release instead of standard-version if it makes sense for them.

Should I always squash commits when merging PRs?

The instructions to squash commits when merging pull requests assumes that one PR equals, at most, one feature or fix.

If you have multiple features or fixes landing in a single PR and each commit uses a structured message, then you can do a standard merge when accepting the PR. This will preserve the commit history from your branch after the merge.

Although this will allow each commit to be included as separate entries in your CHANGELOG, the entries will not be able to reference the PR that pulled the changes in because the preserved commit messages do not include the PR number.

For this reason, we recommend keeping the scope of each PR to one general feature or fix. In practice, this allows you to use unstructured commit messages when committing each little change and then squash them into a single commit with a structured message (referencing the PR number) once they have been reviewed and accepted.
