Mapbox GL Code Flow Example

This repository is a simple example of a development environment for Mapbox GL styles that is based on editing raw code with a text editor. This style of editing is similar to TileMill or the Mapbox Studio desktop tools.

This example is based on Gulp as a framework for its basic utilities:

• A Mapbox GL JS-powered page for previewing the style
• Support for JSON, JSON5, YAML, and TOML files as input. You can also specify an executable JavaScript file with a .js extension and hashbang and the file will be run and its output piped into the style definition.
• Live-reloading when the style is changed

Install

First, clone this git repository:

git clone https://github.com/mapbox/mapbox-gl-codeflow-example.git
cd mapbox-gl-codeflow-example

And then install the dependencies:

npm install

And then start up:

gulp --style=style.json

You can also specify style.json5, style.yml, or style.toml as your inputs. Unlike JSON, these alternative formats support commenting, so you can annotate your styles. Note that this is a one-way conversion, like the conversion from CartoCSS to Mapnik XML was.

Example

This project is an example of one such flow: you could do the same with a bare-bones node.js script, or Python or any other environment. You could also skip some of the fancier features, like live reloading, or add others, like a more complex debugging view.
