Release Notes

socketio/socket.io

v2.4.1

Compare Source

This release reverts the breaking change introduced in 2.4.0 (socketio/socket.io@f78a575).

If you are using Socket.IO v2, you should explicitly allow/disallow cross-origin requests:

  • without CORS (server and client are served from the same domain):
const io = require("socket.io")(httpServer, {
  allowRequest: (req, callback) => {
    callback(null, req.headers.origin === undefined); // cross-origin requests will not be allowed
  }
});
  • with CORS (server and client are served from distinct domains):
io.origins(["http://localhost:3000"]); // for local development
io.origins(["https://example.com"]);

In any case, please consider upgrading to Socket.IO v3, where this security issue is now fixed (CORS is disabled by default).

Features (from Engine.IO)
  • add support for all cookie options (19cc582)
  • disable perMessageDeflate by default (5ad2736)
Bug Fixes
  • security: do not allow all origins by default (f78a575)
  • properly overwrite the query sent in the handshake (d33a619)

⚠️ BREAKING CHANGE ⚠️

Previously, CORS was enabled by default, which meant that a Socket.IO server sent the necessary CORS headers (Access-Control-Allow-xxx) to any domain. This will not be the case anymore, and you now have to explicitly enable it.

Please note that you are not impacted if:

  • you are using Socket.IO v2 and the origins option to restrict the list of allowed domains
  • you are using Socket.IO v3 (disabled by default)

This commit also removes the support for '*' matchers and protocol-less URL:

io.origins('https://example.com:443'); => io.origins(['https://example.com']);
io.origins('localhost:3000');          => io.origins(['http://localhost:3000']);
io.origins('http://localhost:*');      => io.origins(['http://localhost:3000']);
io.origins('*:3000');                  => io.origins(['http://localhost:3000']);

To restore the previous behavior (please use with caution):

io.origins((_, callback) => {
  callback(null, true);
});

v2.1.0

Compare Source

Features
// 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)
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)
  • include the protocol in the origins check (#​3198)
Important note ⚠️ from Engine.IO 3.2.0 release

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

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

v2.4.0

Compare Source

The minor bump is matching the bump of the server, but there is no new feature in this release.

Links:

v2.3.1

Compare Source

The debug dependency has been reverted to ~3.1.0, as the newer versions contains ES6 syntax which breaks in IE
browsers.

Please note that this only applied to users that bundle the Socket.IO client in their application, with webpack for
example, as the "official" bundles (in the dist/ folder) were already transpiled with babel.

For webpack users, you can also take a look at the webpack-remove-debug
plugin.
