Examples

In the next fragments of code you can see different use cases of SSE requests.

• Read a value from the address with a GET petition.
  • response: reponse from the server.

var Wotnectivity = require("wotnectivity-sse");
 
var address = "http://192.168.1.38";
var payload = {};
var configuration = { requestType: "SSE", headers: {content-type:"application/json"}};

let response = await Wotnectivity.sendRequest("http://192.168.1.21/property/status/sse", configuration, payload)
  response.subscribe((data)=>{
    console.log(data)
  })

The configuration parameter of the request needs to have can have the following parameters:

• requestType where the type of request will be declared. The request type can be of three different types:

  • SSE: Sends a SSE request to an address.

• (optional) headers: Defines the headers of the request.

The library works over http and https.
