0.3.0

Features

Add multiplexing support

The streamCount option is added to be able to use multiple Redis streams, allowing to split the load between several Redis nodes.

Note: each namespace is routed to a specific stream to ensure the ordering of messages, so this option only improves scalability when using multiple namespaces.

const io = new Server({
  adapter: createAdapter(redisClient, {
    streamCount: 4
  })
});

Added in ee693d0.

Add option to skip hasBinary() checks

The onlyPlaintext option allows skipping the hasBinary() checks during payload serialization (those checks are necessary as binary data must be base-64 encoded before being sent in the Redis stream).

const io = new Server({
  adapter: createAdapter(redisClient, {
    onlyPlaintext: true
  })
});

Added in 1f7e6fc.

Make BLOCK timeout configurable

The blockTimeInMs option allows configuring the BLOCK timeout used when fetching data from the Redis stream:

const io = new Server({
  adapter: createAdapter(redisClient, {
    blockTimeInMs: 2_000
  })
});

Added in e7653c4.

Use PUB/SUB for fetchSockets() and serverSideEmit() requests

Redis PUB/SUB is now used for transient requests, instead of sending them in the Redis stream.

Two new options:

• channelPrefix: the prefix of the Redis PUB/SUB channels (defaults to "socket.io")
• useShardedPubSub: whether to use sharded PUB/SUB (added in Redis 7.0) (defaults to false)

Each server will use two PUB/SUB channels:

• one common for receiving requests
• one private for receiving responses

Added in dacb88d.
