Show HN: React-Rewrite – A visual editor for React that writes code, no LLM

react-rewrite

lets you edit a React app visually while it is running locally, then automatically writes those changes back to the source files in your project.

It is built for local development and works by opening a proxy in front of your dev server and injecting an overlay into the page.

full demo: https://x.com/imdonghakim/status/2038230475894899119

You do not need to download or clone this repo.

From the root of your React app:

npm install -D react-rewrite-cli

Start your dev server, then in a second terminal run:

npx react-rewrite

If you want to try it without installing first:

npx react-rewrite-cli@latest

• Select an element and inspect its component name, file path, and line number

• Edit supported Tailwind-based layout, spacing, size, typography, and color properties

• Double-click text to edit it inline

• Copy, paste, and duplicate elements

• Delete elements

• Reorder sibling elements

• Stage multiple changes and apply them with Confirm - Undo in-progress canvas changes and review applied changes in the changelog

• Node.js 20+

• A React project (18+)

• A running development server

• Supported app setups: Next.js, Vite, and Create React App

Tailwind CSS is recommended if you want to use the property editor. Text editing and some structural actions do not depend on Tailwind.

Run this in the root of the React app you want to edit:

npm install -D react-rewrite-cli

If you don't want to install it first, you can also run it directly with npx react-rewrite-cli@latest

.

• Start your React dev server as usual.
• In a second terminal, from the same project root, run:

npx react-rewrite

If auto-detection does not pick the right port, pass it explicitly:

npx react-rewrite 3000

The tool opens a local proxy in your browser, shows the editing overlay, and writes confirmed changes back into files inside your project.

• Click an element to inspect and select it.
• Edit properties in the sidebar, drag to reorder where supported, or double-click text to change copy.
• Review pending changes in the UI.
• Click Confirm to apply them to your source files.

react-rewrite [options] [port]

Arguments:
  port           Dev server port override

Options:
  --no-open      Don't open browser automatically
  --host <host>  Dev server host (default: "localhost")
  --verbose      Enable debug logging

• Run react-rewrite

from your app's root directory so it can detect the framework and safely resolve file paths. - It only works against development builds, not production builds.

• Only files inside the current project are eligible for writes.

To work on this repository itself:

pnpm install
pnpm build
pnpm test -- --run

For iterative CLI development:

pnpm dev

You will still need a separate supported React app running locally to test the tool end to end.
