# CUTOS 4.0 Core API Demo The basic CUTOS 4.0 LWA demo. It depends only on `@cutos/core` and does not require an additional Capability SDK or Provider. The demo covers the same foundation as the CUTOS 3.x `demo-core-api`, updated for the Promise-first 4.0 API: - Runtime version and connection state - Platform, runtime config, box, and device information - Network notifications - Logger levels - Volume read/write - Automatic HTTP proxy configuration and a ping request for verifying cross-origin access ## Install ```bash npm install ``` ## Development ```bash npm run dev ``` Development uses CUTOS Mock by default. To connect to a CUTOS Node, set `VITE_CUTOS_BROKER_URL` to its host. ## Build And Package ```bash npm run build ``` The packaged `.lwa` file is generated in `release/`.
