JavaScript/WebGL vector maps library

A WebGL JavaScript interactive maps library that can render Mapbox Vector Tiles.

Setup

To install dependencies and build the source files:

$ npm install

To serve the debug page:

$ npm start &
$ open http://localhost:1337/debug/index.html?access_token=$MapboxAccessToken

This assumes you have the MapboxAccessToken environment variable set to a Mapbox API token from https://www.mapbox.com/account/apps/. It will watch the source files and automatically rebuild the browserify bundle whenever a change is detected.

Tests are written in tape. Most tests run within nodejs, but a few require a browser environment.

• npm test: local tests run in nodejs - excludes browser tests
• npm run cov: generate test coverage report - excludes browser tests
• npm run test-browser: run all tests locally in a browser
