  static async getData() {
    const user = await fetch(
      'https://jsonplaceholder.typicode.com/users/1'
    ).then(res => res.json())
 
    return {

Server-Side Rendering

With two-step rendering on server

// server.js
 
import React from 'react'
import { renderToString } from 'react-dom/server'
import { getAppInitialData } from 'react-get-app-data'
import { html } from 'common-tags'
import App from './app'
 
export default () => (req, res) => {
  const appElement = (<App />)
 
  getAppInitialData(appElement)
    .then((initialData) => {
      const app = renderToString(appElement)
 
      res.send(html`
        <!DOCTYPE html>
        <html>
          <body>
            <div id="app">${app}</div>
            <script>
              (function () {
                window._ssr = ${JSON.stringify({ initialData })};
              })();
            </script> 
            <script src="/client.js"></script> 
          </body>
        </html>
      `)
    })
    .catch((error) => {
      console.error(error)
      res.status(500)
      res.send(`Error: ${error.message}`)
    })
}

Hydrate app and initialData in client

// client.js
 
import React from 'react'
import ReactDOM from 'react-dom'
import { hydrateData } from 'react-get-app-data'
import App from './app'
 
// Get server state
const { initialData } = (window._ssr || {})
 
// Restore app state
hydrateData(initialData)
 
// Render app
ReactDOM.hydrate((
  <App />
), document.getElementById('app'))
