Chrome Extension Developer

Built for anyone shipping Chrome extensions with Manifest V3, this walks you through service workers, content scripts, message passing, and the whole context separation story that trips people up. It's opinionated about doing things the modern way: declarativeNetRequest over webRequest, chrome.storage over localStorage, chrome.alarms for background tasks. The examples cover the boilerplate you actually need, like proper message listener patterns and manifest structure. Honestly most useful if you're migrating from V2 or debugging why your service worker keeps dying. Sticks to Chrome's APIs, so if you're targeting Firefox or Safari you'll need something else.
