Simple way to diff server/browser rendering results

I found this answer at StackOverflow. I think it is useful, so I share with you here.

Browser side

First of all, you should ensure the site is served. Then you can:

• Open your site in any browser
• Open the browser console, and type:

console.log(document.documentElement.innerHTML)

• Copy the output, and save it as client.html

Server side

Supposing your site is running on localhost:3000.

• Open a shell, and type:

curl localhost:3000 > server.html

Compare the differences

You can simply run:

diff client.html server.html

Note that you may need to format both files before diff.
