# React - Vite Federation Demo
2+
3+
This example demos a react application with shared global state using zustand.
4+
5+
## Running
6+
7+
Install `pnpm` as per instructions provided [here](https://pnpm.io/installation)
8+
9+
Run `pnpm install`, then `pnpm run build` and `pnpm run serve`. This will build and serve both `host` and `remote` on ports 5000, 5001 respectively.
10+
11+
- HOST: [localhost:5000](http://localhost:5000/)
12+
- REMOTE: [localhost:5001](http://localhost:5001/)
13+
14+
`CTRL + C` can only stop the host server. You can run `pnpm stop` to stop all services.
