How can I send headers for the handshake with the browser APIs WebSocket?

[jonasfroeller]

I would like to do, what socket.io does, but I want to do it without socket.io, because I do not need all the other stuff, and I do not want to increase traffic by using it just for that.
Does anybody know how to do that? I searched for a solution, but I can not find out, how to do it. I know that Postman can do it, meaning it has to be possible and in the official definition it sounds like it is.

Hi!

How can I send headers for the handshake with the browser APIs WebSocket?

This is not possible, as the WebSocket API in the browser does not provide a way to send HTTP headers. Postman can do it because it's a Node.js client under the hood.

Thank you for the quick response!
Might switch to socket.io now,
although I do not need all the features.
But you have made a lot of sdks
which would probably help me a lot,
because I am building the server
for php, typescript and swift.
And you have implemented authentication,
which can only be implemented in cursed ways
using the browser API.
Thank you for the library!

@darrachequesne This is possible using Direct Socket TCPServerSocket.
