Testing Performance, Speed and Best Practices with Lighthouse
Web Development is an ever changing landscape, and as such we use a variety of tools to evaluate what we do. Like many others with a vested interest in the web, Google has its own projects, and Lighthouse is one of them.
I find the Lighthouse tool particularly interesting for two reasons — firstly because it looks at a few of the more recent specs like Progressive Web Apps and the difficult-to-evaluate concepts like perceived speed, and secondly because it’s developed by Google, which implies that it’s looking at the kind of website optimisations that Google cares about when indexing a website.
A few of the things that Lighthouse currently tests for are:
- Offline/flaky connection support
- Page load performance
- Progressive Enhancement
- Secure connection (HTTPS)
- Page render speed / avoiding “jank”
- Modern accessibility tags
