v2.3.0

Compare Source

This release mainly contains a bump of the engine.io and ws packages, but no additional features.

v2.2.0

Compare Source

Features

• add cache-control header when serving the client source (#​2907) (b00ae50)

Bug fixes

• throw an error when trying to access the clients of a dynamic namespace (#​3355) (a7fbd1a)

v2.1.1

Compare Source

Features

• add local flag to the socket object (#​3129) (1decae3)

socket.local.to('room101').emit(/* */);

v2.1.0

Compare Source

Features

• add a 'binary' flag (#​3185) (f48a06c)

// by default, the object is recursively scanned to check whether it contains some binary data
// in the following example, the check is skipped in order to improve performance
socket.binary(false).emit('plain-object', object);

// it also works at the namespace level
io.binary(false).emit('plain-object', object);

• add support for dynamic namespaces (#​3195) (c0c79f0)

io.of(/^\/dynamic-\d+$/).on('connect', (socket) => {
  // socket.nsp.name = '/dynamic-101'
});

// client-side
const client = require('socket.io-client')('/dynamic-101');

Bug fixes

• properly emit 'connect' when using a custom namespace (#​3197) (f4fc517)
• include the protocol in the origins check (#​3198) (1f1d64b)

Important note ⚠️ from Engine.IO 3.2.0 release

There are two non-breaking changes that are somehow quite important:

• ws was reverted as the default wsEngine (https://github.com/socketio/engine.io/pull/550), as there was several blocking issues with uws. You can still use uws by running npm install uws --save in your project and using the wsEngine option:

var engine = require('engine.io');
var server = engine.listen(3000, {
  wsEngine: 'uws'
});

• pingTimeout now defaults to 5 seconds (instead of 60 seconds): https://github.com/socketio/engine.io/pull/551

v2.0.0

Compare Source

This major release brings several performance improvements:

• uws is now the default Websocket engine. It should bring significant improvement in performance (particularly in terms of memory consumption) (https://github.com/socketio/engine.io/releases/tag/2.0.0)

• the Engine.IO and Socket.IO handshake packets were merged, reducing the number of roundtrips necessary to establish a connection. (#​2833)

• it is now possible to provide a custom parser according to the needs of your application (#​2829). Please take a look at the example for more information.

Please note that this release is not backward-compatible, due to:

• a breaking change related to utf-8 encoding in engine.io-parser (https://github.com/socketio/engine.io-parser/pull/81)
• an update to make the socket id on the client match the id on the server-side (https://github.com/socketio/socket.io-client/pull/1058)

Please also note that if you are using a self-signed certificate, rejectUnauthorized now defaults to true (https://github.com/socketio/engine.io-client/pull/558).

Finally, the API documentation is now in the repository (here), and the content of the website here. Do not hesitate if you see something wrong or missing!
