Example

First import/require react-native-http-server:

    var httpServer = require('react-native-http-server');

Initalise the server in the componentWillMount lifecycle method. When initalising, you'll provide an options object (only the port property is accepted for now) and a callback where requests will be captured and responses returned.

    componentWillMount(){

      var options = {
        port: 1234, // note that 80 is reserved on Android - an exception will be thrown
      };

      // initalise the server (now accessible via localhost:1234)
      httpServer.create(options, function(request, send){

          // interpret the url
          let url = request.url.split('/');
          let ext = url[1];
          let data = JSON.stringify({data: "hello world!", extension: ext});

          //Build our response object (you can specify status, mime_type (type), data, and response headers)
          let res = {};
          res.status = "OK";
          res.type = "application/json";
          res.data = data;
          res.headers = {
            "Access-Control-Allow-Credentials": "true",
            "Access-Control-Allow-Headers": "Authorization, Content-Type, Accept, Origin, User-Agent, Cache-Control, Keep-Alive, If-Modified-Since, If-None-Match",
            "Access-Control-Allow-Methods": "GET, HEAD",
            "Access-Control-Allow-Origin": "*",
            "Access-Control-Expose-Headers": "Content-Type, Cache-Control, ETag, Expires, Last-Modified, Content-Length",
            "Access-Control-Max-Age": "3000",
            "Cache-Control": "max-age=300",
            "Connection": "keep-alive",
            "Content-Encoding": "gzip",
            "Content-Length": data.length.toString(),
            "Date": (new Date()).toUTCString(),
            "Last-Modified": (new Date()).toUTCString(),
            "Server": "Fastly",
            "Vary": "Accept-Encoding"
          };

          send(res);

      });

    }

Finally, ensure that you disable the server when your component is being unmounted.

  componentWillUnmount() {
    httpServer.stop();
  }
