v2.0.0

🚀 Azure Web PubSub store performance improvements

Release date: October 30, 2025

This release improves scalability when using the Azure Web PubSub store, enabling applications to handle very large collaborative rooms more efficiently.

Changed

Improved room loading for Azure Web PubSub Store

The Azure Web PubSub Store has been updated to improve how large rooms are initialized.

Room data loading has been decoupled from the store implementation, allowing applications to control how and where room state is fetched. This enables better scalability when working with large collaborative documents.

Breaking Changes

initialRoomData must now be provided when creating the store

The store no longer fetches room data automatically.

Instead, the initial room state must be passed explicitly via the initialRoomData option when creating the store.

Before (v1.x)

const roomId = "my-room";
const store = new AzureWebPubSubStore(
  {
    getUser: ...
  },
  {
    roomId,
    ...
});

The store internally fetched and reconstructed the room state.

After (v2.0.0)

Applications are now responsible for retrieving the room data and passing it to the store:

const roomId = "my-room";
const roomData = await.fetch(...);
const store = new AzureWebPubSubStore(roomData,
  {
    getUser: ...
  },
  {
    roomId,
    ...
});

Migration steps

1. Fetch the room state from your persistence layer (database, blob storage, etc.).
2. Pass the retrieved state using the initialRoomData constructor option.

This change gives applications full control over room loading strategies and allows Weave.js to scale better with large rooms.
