Develop

Maputnik is written in typescript and is using React and MapLibre GL JS.

We ensure building and developing Maputnik works with the current active LTS Node.js version and above.

Check out our Internationalization guide for UI text related changes.

Getting Involved

Join the #maplibre or #maputnik slack channel at OSMUS: get an invite at https://slack.openstreetmap.us/ Read the the below guide in order to get familiar with how we do things around here.

Install the deps, start the dev server and open the web browser on http://localhost:8888/.

# install dependencies
npm install
# start dev server
npm run start

If you want Maputnik to be accessible externally use the --host option:

# start externally accessible dev server
npm run start -- --host 0.0.0.0

The build process will watch for changes to the filesystem, rebuild and autoreload the editor.

npm run build

Lint the JavaScript code.

# run linter
npm run lint
npm run lint-css
npm run sort-styles

Tests

For E2E testing we use Cypress

Cypress doesn't starts a server so you'll need to start one manually by running npm run start.

Now open a terminal and run the following using chrome:

npm run test

or firefox:

npm run test -- --browser firefox

See the following docs for more info: (Launching Browsers)[https://docs.cypress.io/guides/guides/launching-browsers]

You can also see the tests as they run or select which suites to run by executing:

npm run cy:open

Release process

1. Review CHANGELOG.md
   • Double-check that all changes included in the release are appropriately documented.
   • To-be-released changes should be under the "main" header.
   • Commit any final changes to the changelog.
2. Run Create bump version PR by manual workflow dispatch and set the version number in the input. This will create a PR that changes the changelog and package.json file to review and merge.
3. Once merged, an automatic process will kick in and creates a GitHub release and uploads release assets.
