This is a tiny server that renders a given url and returns it as PNG image. At smallstack.io we use it to render previews of javascript enabled pages.
Note: The server will wait for window.prerenderReady=true to be set unless you set waitforprerender=false!
npm install && npm run serve
docker run -p 80:80 -d smallstack/smallstack-webpage-renderer
The tiny server has only one endpoint so far, which is /render. Possible Parameters are :
