create-embedded-react

Scaffold a new embedded-react app — React Native for embedded MCUs.

npm create embedded-react@latest my-app
# or: npx create-embedded-react my-app

cd my-app
npm install
npm run dev          # WASM simulator with hot reload → http://localhost:3333

The generated project is a minimal starter — a styled card with a pulsing logo and a count is N button — wired for the browser simulator (npm run dev) and a shareable static export (npm run export). Edit App.jsx and save; it hot-reloads. The same code runs on real hardware through the embedded-react C engine.

TypeScript

For a TypeScript starter, add --ts (or --typescript):

npm create embedded-react@latest my-app -- --ts
# or: npx create-embedded-react my-app --ts

The TypeScript template adds a tsconfig.json, ambient type declarations for asset imports (png/ttf/…), and a npm run typecheck script.

Start from a demo

Pass --template <name> (or -t) to scaffold from a full demo app instead of the minimal starter — a ready-made starting point, or a way to try a real UI on your hardware:

npm create embedded-react@latest my-thermostat -- --template thermostat
npm create embedded-react@latest my-watch      -- --template watch-face

List everything available:

npm create embedded-react@latest -- --list

| Template | What you get | | -------------- |-----------------------------------------------| | starter | Minimal starter — pulsing logo + counter (the default). | | starter-ts | The starter in TypeScript (same as --ts). | | thermostat | A thermostat with a 14-day weather panel | | watch-face | A digital watch face + bubble level (RP2040 1.69") |

Every template scaffolds the same way — npm install && npm run dev for the browser simulator, npm run dev:device to hot-reload on a board, npm run build for the device artifact. The demos are the same JSX apps in the monorepo's demos/.
