The Network tab for node
…and much more. netsleuth is a project that brings the Chrome DevTools’ Network tab to node.js – natively. Inspect all outgoing HTTP(S) requests from a node.js process with no code changes.
The project aims to be an all-in-one HTTP toolkit. netsleuth can:
- Inspect any outgoing requests from node process(es) running on your machine. No code changes, proxy configuration, or TLS certificate headaches necessary.
- Act as a proxy server, allowing you to inspect requests between anything.
- As a reverse proxy, it forwards all incoming requests to a target server.
- As a forward proxy, it handles all outgoing requests from a properly configured client to any server.
- Use a public gateway service to forward inspectable incoming requests from the public internet to your local development environment.
- Make HTTP requests from the command line using the
reqCLI (and optionally inspect them in the GUI).
netsleuth uses the powerful and well-known Chrome DevTools GUI that developers are already familiar with. It implements a daemon that speaks the DevTools wire protocol to light up the GUI with request data, and serves a lightly modified version of the DevTools that can be viewed in a normal browser tab.
Bringing this project into reality required an exceptionally deep understanding of many core internet technologies: HTTP, TLS, TCP, DNS, and node.js internals to name a few.
Full details, documentation, and more is available on the netsleuth website.
