Rendering to strings


The aim with rendering components in Node.js is to render to strings, instead of trying to figure out the best way to insert them into the DOM. The string content is then returned to the browser, which displays this to the user immediately. Let's get our feet wet with a basic example. First, we have a simple component that we want to render:

import React, { PropTypes } from 'react'; 
 
const App = ({ items }) => ( 
  <ul> 
    {items.map(i => ( 
      <li key={i}>{i}</li> 
    ))} 
  </ul> 
); 
 
App.propTypes = { 
  items: PropTypes 
    .arrayOf(PropTypes.string) 
    .isRequired, 
}; 
 
export default App; 

Next, let's implement the server that will render this component when the browser asks for it:

import React from 'react'; 
 
// The "renderToString()" function is like "render()", 
// except it returns a rendered HTML string instead of...
