Sample Nest JS app to test Server-Sent Events (SSE) to push unidirectional notifications to UI from API layer without Websockets.

- UI will subscribe to the Server-Sent Events (SSE) endpoint on the NestJS layer on page load for the specified user id in URL (`?userId=2`).

- A `corn scheduler` is setup on the Nest JS layer for every `2 seconds` which will emit message to a random user id.

- The SSE connection will be destroyed on page unload.

## Local setup

```

        $ git clone https://github.com/tamdilip/sse-nest-js.git

        $ cd sse-nest-js

        $ npm start

        $ Visit in Browser -> http://localhost:3000/?userId=2

```
