Exposing streaming API to provide real time updates to the user

Comment

Opens a new event stream according to your request filters. Unlike our other APIs, a request to /api/events/ returns a stream of data, where each line is a JSON object. The response body contains all the events in that stream. Since streams by definition go on forever, Real-time Data Streaming will never end the response without some external reason.

@RestController
@RequestMapping("product")
public class ProductStreamController {

    @Autowired
    private Flux<ProductDto> flux;

    @GetMapping(value = "stream/{maxPrice}", produces = MediaType.TEXT_EVENT_STREAM_VALUE)
    public Flux<ProductDto> getProductUpdates(@PathVariable int maxPrice){
        return this.flux
                    .filter(dto -> dto.getPrice() <= maxPrice);
    }

}
