KneeJerk is a minimal utility for server side React rendering. KneeJerk is server framework agnostic. You simply pass in a react-router configuration and URL, and KneeJerk renders the HTML using react-router. You can optionally pass in a root component to wrap the router output in order to achieve full page rendering.
const KneeJerk = require('kneejerk');
KneeJerk({
root: require('your-html-wrapper.jsx'),
routes: require('your-routes-file.jsx'),
location: '/dashboard'
}, (err, results) => {
reply(results.markup);
});KneeJerk exports a single function, described below.
