The other day, I realized that web performance is an enormous topic covering so very much — from minimizing assets to using certain file formats, it can be an awful lot to keep in mind while building a website. It’s certainly far too much for me to remember! So I made a web performance checklist. It’s a Notion doc that I can fork and use to mark completed items whenever I start a new project. It also contains a bunch of links for references. This doc is still a work in progress. MORE
