0.3.0 (2025-10-16)

This release contains an important refactor of the adapter (this commit), as most of the logic has been moved in the ClusterAdapter class of the socket.io-adapter package.

Besides, the @socket.io/cluster-adapter package is now part of the socket.io monorepo.

0.2.2 (2023-03-24)

The socket.io-adapter package was added to the list of peerDependencies, in order to fix sync issues with the version imported by the socket.io package (see 15fd56e).

Support for connection state recovery (see here) will be added in the next release.

0.2.1 (2022-10-13)

Bug Fixes

• properly handle ERR_IPC_CHANNEL_CLOSED errors (#6) (be0a0e3)

0.2.0 (2022-04-28)

Features

• broadcast and expect multiple acks (055b784)

This feature was added in socket.io@4.5.0:

io.timeout(1000).emit("some-event", (err, responses) => {
  // ...
});

Thanks to this change, it will now work within a Node.js cluster.
