Frank has a great reputation for putting together stunning visual demos with the tiniest amounts of JavaScript. This is no exception. He goes into a lot of detail about how it works; you’ll learn a few things and/or come away awe-struck.

1Password is a popular password management tool that relies upon a browser extension to fill out passwords on the Web. At over a minute for a single build, things were starting to drag for the devs. Could esbuild help? A fun story with plenty of technical details.
