After enabling Greenkeeper for your repository you can use this package to make it work with lockfiles, such as
- ✅ npm (including npm5)
- ✅ yarn
- ✅ Travis CI
- ✅ Circle CI Thank you @ethanrubio 👏
- ✅ Jenkins
- ✅ Wercker
- ✅ Bitrise Thank you @zetaron 👏
- ✅ Buildkite Thank you @justindowning 👏
- 🙏 Contribute your own
How does it work
- Detect whether the current CI build is caused by Greenkeeper
- Update the lockfile with the latest version of the updated dependency using the package manager’s built in mechanism
- Push a commit with the updated lockfile back to the Greenkeeper branch
First create a GitHub access token with push access to your repository and make it available to your CI's environment as
If you use Travis CI, you may add the token using the CLI app as follows:
travis encrypt GH_TOKEN=<token> --add
Configure your CI to use the npm/yarn version you want your lockfiles to be generated with before it installs your dependencies. Install
greenkeeper-lockfile as well.
Configure your CI to run
greenkeeper-lockfile-update right before it executes your tests and
greenkeeper-lockfile-upload right after it executed your tests.
This is how it works on Travis CI for the different package managers.
before_install: # package-lock.json was introduced in npm@5 - npm install -g npm@5 # skip this if you are using node 9 - npm install -g greenkeeper-lockfile@1 before_script: greenkeeper-lockfile-update after_script: greenkeeper-lockfile-upload
before_install: yarn global add greenkeeper-lockfile@1 before_script: greenkeeper-lockfile-update after_script: greenkeeper-lockfile-upload
Custom yarn command line arguments
To run the lockfile-update script with custom command line arguments, set the
GK_LOCK_YARN_OPTS environment variable to your needs (set it to
--ignore-engines, for example). They will be appended to the
yarn add command.
Testing multiple node versions
It is common to test multiple node versions and therefor have multiple test jobs for one build. In this case the lockfile will automatically be updated for every job, but only uploaded for the first one.
node_js: - 6 - 4 before_install: - npm install -g npm - npm install -g greenkeeper-lockfile@1 before_script: greenkeeper-lockfile-update # Only the node version 6 job will upload the lockfile after_script: greenkeeper-lockfile-upload
In order to use
greenkeeper-lockfile with CircleCI workflows, it must be in the first job run. Use sequential job execution to ensure the job that runs
greenkeeper-lockfile is always executed first. For example, if
greenkeeper-lockfile is run in the
lockfile job, all other jobs in the workflow must require the
lockfile job to finish before running:
workflows: version: 2 workflow_name: jobs: - lockfile - job1: requires: - lockfile
Contributing a CI Service
In order to support a CI service this package needs to extract some information from the environment.
- repoSlug The GitHub repo slug e.g.
- branchName The name of the current branch e.g.
- firstPush Is this the first push on this branch i.e. the Greenkeeper commit
- correctBuild Is this a regular build (not a pull request for example)
- uploadBuild Should the lockfile be uploaded from this build (relevant for testing multiple node versions)
Have a look at our Travis CI reference implementation.
Detecting your service
Write a test that returns whether this package runs in your CI service’s environment and add it to our ci-services/tests.
Testing your service
In order to test this plugin with your own CI service install your fork directly from git.
+ npm i -g you/greenkeeper-lockfile#my-ci - npm i -g greenkeeper-lockfile@1
We are looking forward to your contributions 💖 Don’t forget to add your CI service to the list at the top of this file.
