[nofelkad]

With an example from seperate-channel branch

Why does it sends metadata every time?

Below Snippet i tried doesn't work

let payload={
      data: clientRequests,
       metadata: String.fromCharCode('greetings-channel'.length) + 'greetings-channel'
}

 socket
       .requestChannel(Flowable.just({
              data: clientRequests,
              metadata: String.fromCharCode('greetings-channel'.length) + 'greetings-channel',
        }))
         .subscribe({
               onComplete: () => console.log('Request-channel completed'),
               onError: (error => console.error(`Request-channel error:${error.message}`)),
               onNext: (value => console.log(value.data)),
               onSubscribe: (sub => sub.request(10)),
          });

It takes Data all in one
