Release

Automatic release using Jenkins

  • The automatic release is started by creating a Pull Request from develop to master. The pull request status checks correlated to the branch and PR Jenkins jobs need to be processed successfully. 1 review from a github user with rights is mandatory.
  • It runs on every commit on master branch, which is protected from direct commits, only allowing pull request merge commits.
  • The automatic release is done by Jenkins. The status of the release job can be seen both in the Readme.md badges and the green check/red cross/yellow circle near the last commit information. If you click on the icon, you will have the list of checks that were run. The continuous-integration/jenkins/branch link goes to the Jenkins job execution webpage.
  • Automated release scripts are located in the eeacms/gitflow docker image, specifically js-release.sh script. It uses the release-it tool.
  • As long as a PR request is open from develop to master, the PR Jenkins job will automatically re-create the CHANGELOG.md and package.json files to be production-ready.
  • The version format must be MAJOR.MINOR.PATCH. By default, next release is set to next minor version (with patch 0).
  • You can manually change the version in package.json. The new version must not be already present in the tags/releases of the repository, otherwise it will be automatically increased by the script. Any changes to the version will trigger a CHANGELOG.md re-generation.
  • Automated commits and commits with [JENKINS] or [YARN] in the commit log are excluded from CHANGELOG.md file.

Manual release from the develop branch ( beta release )

Installation and configuration of release-it

You need to first install the release-it client.

npm install -g release-it

Release-it uses the configuration written in the .release-it.json file located in the root of the repository.

Release-it is a tool that automates 4 important steps in the release process:

  1. Version increase in package.json ( increased from the current version in package.json)
  2. CHANGELOG.md automatic generation from commit messages ( grouped by releases )
  3. GitHub release on the commit with the changelog and package.json modification on the develop branch
  4. NPM release ( by default it's disabled, but can be enabled in the configuration file )

To configure the authentification, you need to export GITHUB_TOKEN for GitHub

export GITHUB_TOKEN=XXX-XXXXXXXXXXXXXXXXXXXXXX

To configure npm, you can use the npm login command or use a configuration file with a TOKEN :

echo "//registry.npmjs.org/:_authToken=YYYYYYYYYYYYYYYYYYYYYYYYYYYYYY" > .npmrc

Using release-it tool

There are 3 yarn scripts that can be run to do the release

yarn release-beta

Automatically calculates and presents 3 beta versions - patch, minor and major for you to choose ( or Other for manual input).

? Select increment (next version): 
❯ prepatch (0.1.1-beta.0) 
  preminor (0.2.0-beta.0) 
  premajor (1.0.0-beta.0) 
  Other, please specify...
yarn release-major-beta

Same as yarn release-beta, but with premajor version pre-selected.

yarn release

Generic command, does not automatically add the beta to version, but you can still manually write it if you choose Other.

Important notes

Do not use release-it tool on master branch, the commit on CHANGELOG.md file and the version increase in the package.json file can't be done without a PULL REQUEST.

Do not keep Pull Requests from develop to master branches open when you are doing beta releases from the develop branch. As long as a PR to master is open, an automatic script will run on every commit and will update both the version and the changelog to a production-ready state - ( MAJOR.MINOR.PATCH mandatory format for version).
