Usage

Base on project create by create-react-app & react-router-dom

• Install packages

  yarn add koa-react-carvel react react-dom react-router-dom \
  koa koa-router koa-static pm2

• Update index.js

  Use App.js and render elements with hydrate or render accordingly

  import React from 'react';
  import ReactDOM from 'react-dom';
  import Root from './App';
  import * as serviceWorker from './serviceWorker';
  
  const rootElement = document.getElementById('root');
  const renderOrHydrate = rootElement.children.length ? 'hydrate' : 'render';
  ReactDOM[renderOrHydrate]((
      <Root />
  ), rootElement);
  
  // If you want your app to work offline and load faster, you can change
  // unregister() to register() below. Note this comes with some pitfalls.
  // Learn more about service workers: http://bit.ly/CRA-PWA
  serviceWorker.unregister();

• Create server & use koa-react-carvel middleware

  server/index.js

  import path from 'path';
  import Koa from 'koa';
  import serve from 'koa-static';
  import Router from 'koa-router';
  import carvel, { StreamRender } from 'koa-react-carvel';
  
  import Root from '../src/App';
  
  const ssrConfig = {
      buildPath: path.resolve('./build'),
      rootElementId: 'root',
      render: new StreamRender({
          root: Root
      })
  }
  const router = new Router();
  router.get('/', carvel(ssrConfig));
  
  const app = new Koa();
  
  app.use(router.routes());
  app.use(router.allowedMethods());
  app.use(serve(ssrConfig.buildPath));
  
  const port = parseInt(process.env.PORT, 10) || 4000;
  app.listen(port, () => {
      console.log(`Server has started at ${port}`);
  });

• update config & add build script

  add new path to config/paths.js

  appSsrBuild: resolveApp('build-server'),
  appSsrIndexJs: resolveModule(resolveApp, 'server/index'),
  appSsr: resolveApp('server'),

  add new script to package.json

  "watch:server": "node scripts/watch-server.js",
  "start:server": "pm2 start --no-daemon config/pm2.server.dev.config.js",
  "build:server": "node scripts/build-server.js",
  "server": "pm2 start config/pm2.server.prod.config.js",

  add new building files add config/pm2.server.dev.config.js add config/pm2.server.prod.config.js add config/webpack.config.server.js add scripts/build-server.js add scripts/watch-server.js

• Start server & checking

  npm run build
  npm run build:server
  npm run server

  now ssr is working
