Extension.js
A framework for developing, building, and previewing cross-browser extensions with a unified workflow.
What is Extension.js?
Extension.js is a framework for creating browser extensions that work across Chrome, Edge, Firefox, and other browsers. It provides a unified workflow for developing, building, and previewing extensions without requiring manual configuration for each browser.
Developers building browser extensions who want to support multiple browsers without managing separate build processes or configurations.
It simplifies cross-browser extension development by abstracting browser-specific complexities, offering a single toolchain that works with modern JavaScript frameworks and web standards.
