prerender-plugin

Node.js/webpack module/plugin to prerender static HTML in a single-page application.

What is Prerendering?

Prerendering is a process to preload all elements on the page in preparation for a web crawler to see it. If you’re using a Single Page Application (SPA) for a site that’s not behind a login and SEO is an important concern then this plugin could help you easily generate pre-rendered version of your application.

Installation

npm install prerender-plugin

Usage

This package can be used either directly with Node.js or with webpack build process.

Node.js

var PrerenderPlugin = require('prerender-plugin')
new PrerenderPlugin(options).apply()

Webpack

// webpack.config.js or webpack.prod.conf.js
var PrerenderPlugin = require('prerender-plugin')

module.exports = {
  // ...
  plugins: [
    // ...
    new PrerenderPlugin(options)
  ]
}
