What are good alternatives to websocket?
The Best alternative to web socket is Socket.io

I have written applications in WebSockets protocol before. Now that i came to know about a new technology called WebTransport protocol.How is it different from WebSocket protocol and will it replace Websockets in the future?
The code of the PeerServer for PeerJS mostly consists of WebSockets. I don't see any references to WebRTC.
Why are they using WebRTC for connections to the PeerServer? Is this not possible using WebRTC?
In that case, are there really any differences between using Socket.IO or PeerJS for sending messages between clients?
WebRTC only contemplates the connection part between to peers that know each other, as the discovering part is left to be solved by another tool, peerjs is a good tool to that matter...
I would like to use socket.io or engine.io on client, but does it implies having a corresponding implementation on the server ? so socket.io on Client and a Java server with socket.io for instance ? Thx
Yes, a socket.io client must be talking to a socket.io server on the other end. socket.io is its own protocol on top of webSockets so you must have a reciprocal server on the other end that speaks the same protocol.
There are implementations of socket.io server for many server-side languages, including Java, Javascript, C++, C#, etc...
I have seen two implementation of websocket in dart:io and dart:html. Which one should I use? Currently I prefer more the websocket in dart:io since it seems to fit more naturally how dart handle streams and asynchronous programming.
The dart:html library is used on the client-side and can be compiled to JavaScript.
Use dart:io for server-side code.
In a typical setup, you have a web server listening to WebSocket connections from the client, in which case you would use the one from dart:html. But of course you can also initiate WebSocket connections at the server if you ever need :)
dart:io is only available on the server
dart:html is only available in the browser
I'm experimenting with mqttjs and websockets and I wish to be able to send messages from a webpage using websockets without a bridge to an MQTT broker that is run by mqttjs. I can't find any information if this is available or even possible.
I've looked at mosquitto and they have "experimental" websocket support and I would love to find a Node.JS MQTT broker which could offer the same.
Thus far I got the communication working with pywebsocket and Socket.IO. I would really appreciate pointers in any direction if it is possible to use websockets to mqtt without bridging.
Thanks.
Is old question but is good to share my findings.
You can use the mosca broker that is written in node.js and is using mqtt.js
The mosca is supporting classic mqtt connection and mqtt over WS :
MQTT-over-Websockets
Mosca can operate in two modes: Standalone and as a node.js module.
In general mosca can support many types of brokers:

HiveMQ supports native websockets, which means you can use any Javascript MQTT library (like Eclipse Paho.js with websockets. It's perfectly possible to connect some clients vie websockets and other clients via standard TCP connection. The websocket support is stable and used in production.
The only drawback for you could be that HiveMQ is not written in Node.JS.
