socket.io-client 4.5.0

on Node.js Yarn

Features

• add details to the disconnect event (b862924)

The "disconnect" event will now include additional details to help debugging if anything has gone wrong.

Example when a payload is over the maxHttpBufferSize value in HTTP long-polling mode:

socket.on("disconnect", (reason, details) => {
  console.log(reason); // "transport error"

  // in that case, details is an error object
  console.log(details.message); "xhr post error"
  console.log(details.description); // 413 (the HTTP status of the response)

  // details.context refers to the XMLHttpRequest object
  console.log(details.context.status); // 413
  console.log(details.context.responseText); // ""
});

• add support for catch-all listeners for outgoing packets (74e3e60)

This is similar to onAny(), but for outgoing packets.

Syntax:

socket.onAnyOutgoing((event, ...args) => {
  console.log(event);
});

• slice write buffer according to the maxPayload value (46fdc2f)

The server will now include a "maxPayload" field in the handshake details, allowing the clients to decide how many packets they have to send to stay under the maxHttpBufferSize value.
