Release Process

Overview

The release cadence is optimized for consistency – new releases happen weekly, on the same day of the week (Wednesday)
Out-of-band releases can & do happen to address critical security bugs or patch a broken release & we sometimes elect to skip weeks where there is competing priorities or vacation/OOO
There is only one officially supported release branch: npm@latest) (ie. the latest/stable version of npm)
- Our team does not support any LTS releases - you can read more about the versions of npm we support here.

Note: We're currently shipping weekly releases of npm@latest every Wednesday (& occasionally even more than once a week).

Roles

Each release has a release manager, who is responsible for landing that release's pull requests and dependency upgrades, ensuring that the tests pass for the release branch, writing the release notes, and running through the actual release process (see below). The current release managers are the npm CLI team:

Darcy Clarke / @darcyclarke
"nlf" / @nlf
"gar" / @wraithgar
Luke Karrys / @lukekarrys
Nathan Fritz / @fritzy

Setting up to do releases

If you're a new release manager, you need a GPG key to sign releases with. We've been using https://keybase.io/ to store/verify our public keys.

In order to sign the release tags, you will need to set this also: npm config set sign-git-tag true

Release Please

Much of the release process is automated using a customized release-please script in @npmcli/template-oss.

The configuration for release-please is located in a root repo config file release-please-config.json.

Major Releases and Prereleases

When creating a new major release, first set the prerelease: true flag in the release-please config, and then continue to use conventional commits to indicate changes and cut a branch for the latest version of the previous major.

Cut a release/v<CURRENT_MAJOR> branch

git checkout latest
git checkout -b release/v<CURRENT_MAJOR>
git push -u origin release/v<CURRENT_MAJOR>
git checkout latest

Update releases.json in npm/documentation with the new branches

Set prerelease: true for all packages in release-please-config.json

// ./release-please-config.json
{
  ...
  "packages": {
    ".": {
      ...
      "prerelease": true
    }
  }
  ...
}

Commit prerelease: true as feat:

git checkout -b prerelease
git commit -am "feat: set prerelease flag"
gh pr create -f

Continue to use conventional commits and feature PRs

Everything is now identical to normal release development. The only difference is that release-please will version and tag all releases with a -pre.<PRE_ID> suffix.

The usual release process should be followed, except for the sections marked NOT FOR PRERELEASE.
```
git checkout latest
git checkout -b me/my-breaking-feature
git commit -m 'feat: break stuff

BREAKING CHANGE: this message gets added to the changelog'
gh pr create -f
```

One month later…, remove prerelease flag and commit

Warning: All breaking changes must be merged AND released before this step

git checkout latest
# Remove `prerelease` flags from manifest
git commit -am "feat: remove prerelease flags"
# `release-please` uses the convention of an empty commit
# to force all packages to be released
git commit -m "feat: trigger release process" --allow-empty
# this cannot be made into a PR because rebasing on GitHub
# will remove the empty commit
git push origin latest

This will trigger a new release without a -pre.<PRE_ID> suffix that can be merged and published normally.

Combine all prerelease changelogs into the final GitHub Release notes

release-please only generates changelogs based on the diff from the previous prerelease. So when coming out of prerelease mode, we combine all the prerelease changelogs and manually update the notes of the GitHub Release after it has been created.

The GitHub Release notes are the source of truth for the Node.js pull request as well.

Setting a New Major Version as Latest

The following steps need to be followed when a new major version is tagged latest for the first time. This will not always occur at the same time as a major version coming out of prerelease mode.

Update releases.json in npm/documentation so the branch and spec of the new and previous major releases point to the correct place.

Set the latest dist-tag of the new major version:

node . dist-tag add npm@<NEW-MAJOR.Y.Z> latest

TODO: There may be more of these?

Warning: There are probably more steps here!

Weekly Tasks

Merging Pull Requests

Search for PRs to merge

Some helpful gh searches:

gh pr list --draft=false --search "status:pending"
gh pr list --draft=false --search "status:success"
gh pr list --draft=false --search "review:required"
gh pr list --draft=false --search "review:approved"

Make sure the PR is targeting latest and not something else
```
gh pr view --json baseRefName -q '.baseRefName'
```
Merge the pull request using squash or rebase

Note: Prefer using rebase if the PR has multiple conventional commits.

Squash
```
gh pr merge -s <pr-num>
```
Rebase
```
gh pr merge -r <pr-num>
```

Updating Dependencies

Note: Workspace do not need to be updated, since the automated release process will sync all workspace versions as part of the release pull request.

Dependency updates should all go through pull requests using the deps: conventional commit prefix. This section shows how to check for any outdated deps and make pull requests for them.

Check all top level deps
```
node . outdated
```
Check all levels of production deps
```
node . outdated -a --omit=dev
```

Install and commit each dep to a PR

git checkout -b deps/updates
node . install <pkg>@<version>
node . run dependencies
# Use prefix `chore:` for dev deps
git commit -am 'deps: <pkg>@<version>'
git push origin deps/updates
gh pr create -f

Merge the PR if things look ok

Updating `@npmcli/template-oss`

Note: @npmcli/template-oss is a dependency of all workspaces and must be installed with --save-exact

Update @npmcli/template-oss in all workspaces and root

node . i @npmcli/template-oss@latest -ws -iwr --save-exact

Commit and open PR

git checkout -b deps/template-oss
git commit -am 'chore(deps): @npmcli/template-oss@<version>'
git push origin deps/template-oss
gh pr create -f

Release Day Tasks

Update any last minute deps

See Updating Dependencies for the process.

Release the CLI and workspaces

Note: A single release pull request is created for the CLI and all dependent workspaces by release-please.

The release pull request is created automatically by release-please whenever a commit is pushed to the default branch. This PR should be left open until Release Day, when it should be checked to make sure all workflows are passing. You should checkout the branch locally and publish from there. Once everything is published the PR can be merged into latest.

Checkout the release branch

Ensure git status is not dirty on this branch after resetting deps. If it is, then something is probably wrong with the automated release process.
```
gh pr checkout <PR-NUMBER> --force
node . run resetdeps
node scripts/git-dirty.js
```
Check CI status
```
gh pr checks --watch
```
Publish the CLI

Warning: This will publish all updated workspaces, and will publish the CLI with the dist-tag set to next-<MAJOR>.

Note: The --test argument can optionally be omitted to run the publish process without running any tests locally.
```
node scripts/publish.js --test
```

Optionally install and test npm@<X.Y.Z> locally

npm i -g npm@<X.Y.Z>
npm --version
npm whoami
npm help install
# etc

Set latest dist-tag to newly published version

Warning: NOT FOR PRERELEASE: Do not run this step for prereleases or if <MAJOR> is not being set to latest.
```
node . dist-tag add npm@<X.Y.Z> latest
```

Merge release PR

gh pr merge --rebase
git checkout <BASE-BRANCH>
git fetch
git reset --hard origin/<BASE-BRANCH>
node . run resetdeps

Check For Release Tags

Release Please will run on the just pushed release commit and create GitHub releases and tags for each package.
```
gh run watch `gh run list -w release -L 1 --json databaseId -q ".[0].databaseId"`
```

Post on Twitter

New @npmjs release: <X.Y.Z>!

<GITHUB-RELEASE-LINK>

Release details...

Trigger docs.npmjs.com update

gh workflow run update-cli.yml --repo npm/documentation

Open nodejs/node PR to update npm to latest

Warning: NOT FOR PRERELEASE: Do not run this step for prereleases or if <MAJOR> is not being set to latest.

Trigger the Create Node PR action:
```
