A server-rendering helper module for styletron
const styletronServer = require('styletron-server');
const renderApp = function mockRenderFn() {
/**
* `renderApp` is some function that renders your app, returning a string of HTML.
* This function should also result in `injectOnce` being called at some point.
*/
};
const {html, css, hydrationSrc} = styletronServer.renderStatic(() => {
const html = renderApp();
return html;
}
/**
* `html` is simply the return value of the function passed into `renderStatic`.
* It is passed through for convenience.
*/
/**
* `css` is a string containing all CSS that was that injected into the buffer
* during the render.
*/
/**
* `hydrationSrc` is a string of JS source code to hydrate styletron on the client.
* This script injects a <style> element containing the server-rendered styles and also
* prevents re-injection of server-rendered styles on subsequent client renders.
* Set this string as the contents of a <script> element in <head> so it is before <body>
* and your client bundle.
