A thin wrapper for OpenLayers3 in React.

The goal is to be able to write applications using OpenLayers maps in a declarative way. For example, the following is JSX, which can be returned by the render() method on a React component, to generate a map with a red square near the equator.

<Map view=<View resolution={10000} center={[0, 0]}/>>
  <layer.Tile>
    <source.OSM />
  </layer.Tile>
  <layer.Vector>
    <source.Vector>
      <Feature style={{stroke: {color: [255, 0, 0, 1]}}}>
        <geom.LineString>
          {[[0, 0], [100000, 0], [100000, 100000], [0, 100000]]}
        </geom.LineString>
      </Feature>
    </source.Vector>
  </layer.Vector>
</Map>

To understand what each element does, read the OpenLayers API documentation.

Styles

Are declared using a JSON object, passing through the properties you'd like on the final object.

When creating an Icon, Circle or RegularShape, a type parameter must be present, with the value of icon, circle, or regular-shape.

Example:

image: {
    type: 'circle',
    radius: 10,
    fill: { color: '#666666' },
    stroke: { color: '#bada55', width: 1 }
}

It's early days! If you're familiar with react and/or openlayers and are interested in helping, please get in touch. Available on github and npm.

I am especially interested in assistance with having each component be optionally controlled. This would allow binding of the components with, say, Redux and for sophisticated state management outside of OpenLayers.
