The undocumented Lighthouse guide

Lighthouse is the go-to tool for improving the quality of web pages. Lately, I have been using Lighthouse a lot at work to identify opportunities for performance optimizations. This post is part of a 6 part series that I have written about how to get the most out of Lighthouse.

My experience using Lighthouse in the real world

Lighthouse has been part of my daily work for the last few months and I shared some snippets in my last few posts. For this particular post, it is time to share how I am using Lighthouse in a product used by millions of people and what I have discovered during this process.

HAR (HTTP Archive) is a JSON file containing all information about a browser’s interactions with a page. This file is often used for performance analysis. Earlier this year, I shared what kind of information we can get from and today we will automate the HAR creation.
