Project / Code Review genie-react: Let coding agents inspect your running React app

Coding agents can read your React source, but they can’t see what the running app is actually doing. Ask “why did this effect run six times?” and they’re often left guessing.

genie-react is an open-source CLI that gives any coding agent access to live React internals:

  • Render counts, timings, and the exact prop breaking memoization
  • Effect-loop tracing, including which dependency changed on each run
  • Caught errors and stuck Suspense boundaries
  • Runtime prop and state overrides to test component states
  • TanStack Query cache, invalidations, and Router state

It works with Claude Code, Cursor, and any other agent that can run a CLI.

The demo below uses Excalidraw’s real codebase.

If this solves a problem you’ve hit, a star would help others discover it.

Hey Community,

We explore Grok Build, the new terminal-based TUI coding agent from x.ai. We also look at Appless, an experiment from the creators of OpenUI that bypasses chat bubbles to stream live native UI components using openui-lang.

Finally, we dive into Maestro MCP, a new tool context protocol server that lets AI agents automatically build and run YAML test flows from plain English instructions.

If the Rewind made you nod, smile, or think "oh… that's actually cool" — a share or reply genuinely helps ❤️

General Discussion Building my first full stack project

0 Upvotes

I started learning web development at the start of this year and one thing led to another and I’m now trying to build near enough an entire business’ online system.

I’m building an AI and automation enhanced business simulation.

There’s two main purposes: teach myself full stack development, and experiment with where AI and automation fits in modern business systems. I’m trying to treat it like a real business so I can see how and where things can be different to a system that doesn’t use AI or workflow automation.

It started off as an attempt to build the frontend a customer would use so I could practice with state. Then I decided it would be cool to have the opposing merchant interface where you can view the orders. So I needed to make the backend.

But, given the times we’re in, I thought it would be interesting to see I can use AI and automation in ways that would save a user time, or just deliver helpful results.

Now, my long term plan is to create an entire product pipeline, with product suggestions from a ‘supplier’, marketing content created, product going to warehouse, then product available for order. But that’s a ways off.

For now I’m focused on developing the customer and merchant ends with these primary features:

·       Shared backend

·       Customer service chatbot on customer side

·       AI assistant on merchant side

·       AI overwatch feature to monitor AI behaviour

Eventually I’d like to experiment with adding analytics and CEO suggestions features from the AI but again that’s a ways off.

I’ve set up self-hosted n8n which I’ll use for workflows where necessary, and I think once the meat of the project is done I’ll get a bit creative with that.

I’m building it in slices; rather than trying to make the whole backend at once, I’m building it by function. Currently, I’m on the first slice, the cart. This is my first time attempting to write backend code.

What I’m enjoying is the logical, layered approach; I have router, application, service and data layers, each with their own jobs. And because the backend is entirely abstract so I cant rely on looking at where my elements are going on screen (like with frontend) I’m learning to properly understand how data is passed with javascript.

I realised early on that if I’m to have an AI logging system I’ll have to think data first, and I think this has helped me massively as now it’s simply (simply) a case of getting from the front to the back and adding/changing data whose properties I’ve already determined.

I’m going to post more detailed stuff so I can learn from people on here and engage in general in the topic more.

If anyone has any questions or suggestions, please comment!

I just launched my Alpaki project using React, and I’m really impressed. It’s the first time I’ve seen these web speed scores, and everything is running... beautifully.
