Frontend Architecture and Data Flow

step 1：part Bootstrap，File: src/entrypoints/core.js，When the frontend loads，This is a  script which is the first thing that is loaded on the page. It is responsible for checking for authentication credentials and setting up the websocket connection with the Home Assistant instance.

part App shell，File: src/entrypoints/app.js

This is everything that is required to render the sidebar and handle the routing.

Step 2：The frontend leverages the Websocket API and the Rest API to interact with Home Assistant.

Step 1：you need HA to be accessible from the internet.

Home Assistant is on an IP like 192.168.1.4 and listening on port 8123

Step 2：do a port-forwarding on your router

This requires opening a port on your router and getting a name for your Home Assistant on the internet.

While it is possible to have your HA use Port 8123 internally and have your router do a port-forwarding from say the default https port of 443 to 8123
