This is a simple wrapper around OpenLayers using a monkey-patched jsdom that allows Server-Side Rendering in Node.js
It is meant to be used as a plugin for rlayers
A stand-alone test example is included in render.test.js and can be used as an inspiration for your own implementation.
If you want to run it, there is a transpiled version in the NPM package: index.cjs
# Once you have rlayers installed
npm install --save ol-ssr jsdom canvas
It will enable the RSSRender() call in rlayers
