5.2.2

What's Changed

• fix max call stack exceeded when applying fossil delta by @FZambia in #293
• Bump braces from 3.0.2 to 3.0.3 by @dependabot in #291
• Bump ws from 8.14.1 to 8.17.1 by @dependabot in #290

Full Changelog: 5.2.1...5.2.2

5.2.1

What's Changed

• Synchronize subscribe with unsubscribe to properly work in emulation case by @FZambia in #288. This solves a possible race condition when working with HTTP-streaming and SSE fallback transports and issuing subscribe/unsubscribe requests quickly - the race could lead to already subscribed error.

Full Changelog: 5.2.0...5.2.1

5.2.0

What's Changed

• Support delta compression by @FZambia in #282 . See Centrifugo v5.4.0 release notes for more details

Full Changelog: 5.1.1...5.2.0

5.1.1

What's Changed

• Fix reconnect on close before transport open by @FZambia in #281 . If you observed rare WebSocket is closed before the connection is established warnings in console and no reconnect after that - this should fix it.

What's Changed

• Send commands based on transport state instead of connected state by @ThisIsEsh in #278.

The above pull request, contributed by @ThisIsEsh, changes how centrifuge-js interacts with transport in the bidirectional case. Now, the client sends commands as soon as the transport is ready, instead of waiting for the connect reply. This should reduce the time until the initial subscription in some cases. In fact, this approach makes all subscriptions optimistic.

More importantly, it eliminates the race conditions we had when unsubscribing from channels. Previously, in some cases, unsubscribe frames could be omitted by centrifuge-js (see more details about when exactly in #274). This could result in an already subscribed error when the client tried to subscribe to the channel again.

The change also includes unsubscribe fixes for the emulation transport where centrifuge-js used optimistic subscriptions. When unsubscribe was called before the transport was established, we received a node not found error on the server side. Disabling optimistic subscriptions in the emulation case and adding new logic in #278 now result in correct unsubscribe behavior. Actually, we had already disabled optimistic subscriptions for SSE transport before, so this adjustment only affects emulation based on HTTP streaming.

What's Changed

In v5 release we are moving to Rollup to build the library. For centrifuge-js this means both ESM and CommonJS support and thus solving some issues when users could not use SDK with their existing toolchains (ex. #232, #245). The migration includes changes in how we provide Protobuf version of Centrifuge client. That's why we've made a new major v5 release.

For users which work with JSON-based Centrifuge client (default behaviour) the migration to v5 should be smooth and require no code changes.

Users of Protobuf version of the client need to change how they import Centrifuge when using the library. Also, we removed protocol option of Centrifuge instance config object. Imported Protobuf client now automatically uses Protobuf protocol under the hood.

For example, previously, when using Protobuf version of Centrifuge client, you have to import Protobuf client and then provide an option to constructor:

import Centrifuge from 'centrifuge/build/protobuf';

const centrifuge = new Centrifuge('wss://centrifuge.example.com/connection/websocket', {
    protocol: 'protobuf'
});

Now this simplifies to:

import { Centrifuge } from 'centrifuge/build/protobuf';

const centrifuge = new Centrifuge('wss://centrifuge.example.com/connection/websocket', {});

Note - changed import and no need to pass protocol: 'protobuf'. See readme for more information about using Protobuf client and constructing binary payloads.
