Vite is a fast and efficient WebD build tool to build and serve web apps
1. instant server start and fast code reloading make development a breeze.
2. PROD builds are optimized for performance, resulting in smaller bundle sizes and faster load times.
3. not work seamlessly with older browsers.
4. Hot Module Replacement (HMR) is a feature that allows developers to update and reload individual modules (e.g., JavaScript files) without requiring a full page reload. 
   This enables a faster and more efficient development experience.

what is the time duration of SSE for keep-alive connection ?

  The time duration of an SSE (Server-Sent Events) keep-alive connection can vary depending on several factors, including:
  Server configuration: The server can specify a keep-alive timeout using the Keep-Alive header or other configuration settings.
  Client configuration: The client can also specify a keep-alive timeout using the Keep-Alive header or other configuration settings.
  Network conditions: Network conditions, such as latency and packet loss, can affect the keep-alive timeout.
  Typically, the keep-alive timeout for SSE connections ranges from a few seconds to several minutes. Here are some common values:
    Default timeout: 30 seconds to 1 minute
    Typical timeout: 1-5 minutes
    Maximum timeout: 30 minutes to 1 hour
