Server Side Render add-on for React Loadable. Load splitted chunks was never that easy.
Server Side Render add-on for React Loadable. Load splitted chunks was never that easy.
React Loadable SSR Add-on is a server side render add-on for React Loadable
that helps you to load dynamically all files dependencies, e.g. splitted chunks, css, etc.
Oh yeah, and we also provide support for SRI (Subresource Integrity).
Download our NPM Package
npm install react-loadable-ssr-addon
# or
yarn add react-loadable-ssr-addon
Note: react-loadable-ssr-addon should not be listed in the devDependencies.
First we need to import the package into our component;
const ReactLoadableSSRAddon = require('react-loadable-ssr-addon');
module.exports = {
entry: {
// ...
},
output: {
// ...
},
module: {
// ...
},
plugins: [
new ReactLoadableSSRAddon({
filename: 'assets-manifest.json',
}),
],
};
// import `getBundles` to map required modules and its dependencies
import { getBundles } from 'react-loadable-ssr-addon';
// then import the assets manifest file generated by the Webpack Plugin
import manifest from './your-output-folder/assets-manifest.json';
...
// react-loadable ssr implementation
const modules = new Set();
const html = ReactDOMServer.renderToString(
<Loadable.Capture report={moduleName => modules.add(moduleName)}>
<App />
</Loadable.Capture>
);
...
// now we concatenate the loaded `modules` from react-loadable `Loadable.Capture` method
// with our application entry point
const modulesToBeLoaded = [...manifest.entrypoints, ...Array.from(modules)];
// also if you find your project still fetching the files after the placement
// maybe a good idea to switch the order from the implementation above to
// const modulesToBeLoaded = [...Array.from(modules), ...manifest.entrypoints];
// see the issue #6 regarding this thread
// https://github.com/themgoncalves/react-loadable-ssr-addon/issues/6
// after that, we pass the required modules to `getBundles` map it.
// `getBundles` will return all the required assets, group by `file type`.
const bundles = getBundles(manifest, modulesToBeLoaded);
// so it's easy to implement it
const styles = bundles.css || [];
const scripts = bundles.js || [];
res.send(`
<!doctype html>
<html lang="en">
<head>...</head>
${styles.map(style => {
return `<link href="/dist/${style.file}" rel="stylesheet" />`;
}).join('\n')}
<body>
<div id="app">${html}</div>
${scripts.map(script => {
return `<script src="/dist/${script.file}"></script>`
}).join('\n')}
</html>
`);
See how easy to implement it is?

const styles = bundles.css || [];
