Maputnik
A free and open visual editor for the MapLibre GL styles targeted at developers and map designers.
Usage
- 🔗 Design your maps online at https://www.maplibre.org/maputnik/ (all in local storage)
- 🔗 Use the Maputnik CLI for local style development
- In a Docker, run this command and browse to http://localhost:8888, Ctrl+C to stop the server.
docker run -it --rm -p 8888:80 ghcr.io/maplibre/maputnik:main
Documentation
The documentation can be found in the Wiki. You are welcome to collaborate!
- 🔗 Study the Maputnik Wiki
- 📹 Design a map from Scratch https://youtu.be/XoDh0gEnBQo
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
- 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.
- 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.jsonfile to review and merge. - Once merged, an automatic process will kick in and creates a GitHub release and uploads release assets.
