A grunt task that fetches html snapshots of your web app for easier SEO


Makes it easy to provide html snapshots for client side applications so that they can be indexed by web crawlers

This plugin requires Grunt ~0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-html-snapshot --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:


Run this task with the grunt htmlSnapshot command.

        htmlSnapshot: {
            all: {
              options: {
                //that's the path where the snapshots should be placed 
                //it's empty by default which means they will go into the directory 
                //where your Gruntfile.js is placed 
                snapshotPath: 'snapshots/',
                //This should be either the base path to your index.html file 
                //or your base URL. Currently the task does not use it's own

                //functional configure it here. 
                sitePath: 'http://localhost:8888/my-website/',
                //you can choose a prefix for your snapshots 
                //by default it's 'snapshot_' 
                fileNamePrefix: 'sp_',
                //by default the task waits 500ms before fetching the html. 
                //this is to give the page enough time to to assemble itself. 
                //if your page needs more time, tweak here.

                sanitizefunction (requestUri) {
                    //returns 'index.html' if the url is '/', otherwise a prefix 
                    if (/\//.test(requestUri)) {
                      return 'index.html';
                    } else {
                      return requestUri.replace(/\//g, 'prefix-');
                //if you would rather not keep the script tags in the html snapshots
