Azure Active Directory SDK projects welcome new contributors. This document will guide you through the process.
Please visit https://cla.microsoft.com/ and sign the Contributor License Agreement. You only need to do that once. We can not look at your code until you've submitted this request.
Fork/Clone the project on GitHub and check out your copy. Be aware that unless you have the correct permissions, you will not be able to create new branches on a cloned version of the repository. For all external contributions, please fork this repository.
Example for JS:
$ git clone [email protected]:username/microsoft-authentication-library-for-js.git
$ cd microsoft-authentication-library-for-js
$ git remote add upstream [email protected]:AzureAD/microsoft-authentication-library-for-js.git
Now decide if you want your feature or bug fix to go into the dev branch or the master branch. All bug fixes and new features should go into the dev branch.
The master branch is effectively frozen; patches that change the SDKs protocols or API surface area or affect the run-time behavior of the SDK will be rejected.
Some of our SDKs have bundled dependencies that are not part of the project proper. Any changes to files in those directories or its subdirectories should be sent to their respective projects. Do not send your patch to us, we cannot accept it.
In case of doubt, open an issue.
Especially do so if you plan to work on a major change in functionality. Nothing is more frustrating than seeing your hard work go to waste because your vision does not align with our goals for the SDK.
Okay, so you have decided on the proper branch. Create a feature branch and start hacking:
$ git checkout -b my-feature-branch
This repository is a monorepo for all packages maintained by the MSAL.js team. It contains public npm packages in the lib folder as well as some additional libraries in the extensions folder.
If you would like to build a specific package, you can visit the README.md for that specific folder to review the build process. The instructions here are specific to the monorepo.
// Change to the root of the msal repo
cd microsoft-authentication-library-for-js/
// Install npm dependencies and bootstrap packages
npm install
// Navigate to package you would like to build
cd lib/<package-name>
// Build library
npm run build:all
// To run build only for a single package (not its dependencies)
npm run buildBug fixes and features should come with automated tests. Add your tests in the test directory. This varies by repository but often follows the same convention of /src/test. Look at other tests to see how they should be structured (license boilerplate, common includes, etc.).
Make sure that all previously passing and new tests pass before submitting your change. You can run the tests as described below.
// Change to the root of the msal repo
cd microsoft-authentication-library-for-js/
// Install npm dependencies and bootstrap packages
npm install
// Navigate to package you would like to build
cd lib/<package-name>
// Run test command
npm test// Change to the root of the msal repo
cd microsoft-authentication-library-for-js/
// Install npm dependencies and bootstrap packages
npm install
// Navigate to package you would like to build
cd lib/<package-name>
// Run test command
npm run test:coverageWe will automatically run lint as our pre-commit command. Failing to pass linting will prevent you from pushing up code which will break the build.
$ npm run lint
This will ensure any changes are consistent with the current code style. We uses eslint and you can find a list of linting rules in the .eslintrc.json.
If for some reason you still want to push without fixing the linting errors. You can add the follow option to your commit command to bypass the pre-commit:
--no-verify
Make sure git knows your name and email address:
$ git config --global user.name "J. Random User"
$ git config --global user.email "[email protected]"
Writing good commit logs is important. A commit log should describe what changed and why. A good commit log looks like this:
fix: explaining the commit in one line
The header line should be meaningful; it is what other people see when they run git shortlog or git log --oneline.
Check the output of git log --oneline files_that_you_changed to find out what directories your changes touch.
Use git rebase (not git merge) to sync your work from time to time.
$ git fetch upstream
$ git rebase upstream/dev
$ git push origin my-feature-branch
Once your changes have all been pushed to your branch and you are confident that the code is ready to be reviewed, you can open a new pull request. This will create a form and notify the code owners that you are ready to merge a change. This will also run some pipeline build and test tasks to make sure that there are no errors in the build.
Pull requests are usually reviewed within a few days. If there are comments to address, apply your changes in a separate commit and push that to your feature branch. Post a comment in the pull request afterwards; GitHub does not send out notifications when you add commits.
Once your PR is created, you will need to make sure all of the checks for the PR are passing, including the beachball commands below.
The beachball package is used to compile changelogs and perform releases of the packages. It does this by collecting changefiles for each affected package before a PR is merged. Ensure you have the correct email set in your local git config before continuing. See above.
You will need to add the changefiles to your branch before it can be merged. There are a few scripts added to the package.json to support this:
npm run beachball:change
Generates a changefile based on the master branch. This should be run on your PR before merging to dev, AFTER you have created your PR. When this command is run, the type of change needs to be selected:
Here are the criteria for each type of change:
None: Used for changes to documentation, build files, test files or samples.Patch: Used for bug fixes and minor convenience features.Minor: Used for new features and major bug fixes.Major: Used for new major library changes. Should almost never be used.
beachball will then ask for the changelog message. Please enter a short description of the change as well as the PR number in parentheses at the end of the message. This does not need to be a verbose message.
npm run beachball:check
Checks that changefiles have been generated for relevant changed packages. Used by the CI tool on PRs, can also be used locally.
npm run beachball:bump
Bumps versions for packages with relevant changefiles. Run on master branch to check which packages are slated for release.
IMPORTANT NOTE: This should NOT be done when merging a PR. You should ONLY do this on your local branch to ensure there are no unexpected changes.
Releases are managed using the beachball package. In short, beachball will enforce that every PR to a release branch includes a changefile that will describe the feature as a changelog item. During publish, the package will compile changes for all relevant packages and perform a release to npm.
Releases are generally performed on a regular cadence, and if there is an urgent need can be performed immediately. Please reach out to the codeowners for any questions.
