Render-it NPM | npm.io

Render It :pencil:

Render any JavaScript content to create static sites ready for SEO.

$ yarn add --dev render-it

$ npm install --save-dev render-it

Render it uses Headless Chrome to render the JavaScript content and JSDOM to replace the content in the original HTML document.

Motivation

If you are here, you probably have a problem like this:

Your server is returning a HTML structure without the content that JavaScript renders.

<!-- DOCUMENT HTML -->
<!DOCTYPE html>
<html>
  <body>
    <div>Content from the server</div>
    
    <div id='root'></div> <!-- placeholder for JavaScript to render content -->
  </body>
</html>

But you want to return the document HTML with the content (usually for SEO and SMO).

<!-- DOCUMENT HTML -->
<!DOCTYPE html>
<html>
  <body>
    <div>Content from the server</div>
    
    <div id='root'>Content from the client</div>
  </body>
</html>

Render It allows you to generate all the static pages WITH the content. It returns the same HTML structure from the server but with the JavaScript content inside the placeholder.

Why is it awesome?

Zero config required in the server side.
Zero config required in the client side.
Works with any server language.
Works with any JavaScript library or framework. (like React, VueJS, Angular)
Just render what you need.
Does not depend on Webpack.
Allows a production site URL to generate the static pages.

Usage

Create a Node task to generate the static pages.

// render-it.js

const renderIt = require('render-it')

const config = {
  url: 'http://localhost:3000',
  paths: ['/', '/about', '/contact'],
  selector: '#root',
  outputFolder: 'dist'
}

renderIt(config)

Then you can run it with: node ./render-it.js

So, you can use this task in any environment with Node.
