Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

Welcome to the DevTools wiki!
Overview
Developer Tools consist of 4 main parts:
-
The protocol (usually referred to as Remote Debugging Protocol) defines the debugging (inspection) capabilities. Backend and frontend talk to each other using this protocol. It's divided into domains which represent semantical aspects of the inspected entity. Each domain defines types, commands (messages sent from frontend to backend) and events (messages sent from backend to frontend). The protocol operates over json rpc 2.0.
-
The backend is an inspectable entity implementing the protocol (or parts of it). Chromium Backend supports JS and Browser protocols. There are other backends like standalone V8 or Node.js.
-
The frontend usually connects to a backend and uses protocol to do useful work. It could be showing UI to the user (as Developers Tools do) or perform automation testing or audit the page or do something completely different.
-
The message channel is a way to send protocol messages between backend and frontend.
