v2.18.0

Introducing user notification settings. You can now create beautiful user notification settings pages in your app.

Our packages @liveblocks/client, @liveblocks/react and @liveblocks/node are now exposing functions to manage user notification settings on different notification channels and kinds.

You can support thread, textMention and custom notification kinds (starting by a $) on email, Slack, Microsoft Teams and Web Push channels.

You can choose from our new notifications dashboard page to enable or disable notification kinds on every channels you want to use in your app. It means our internal notification system on our infrastructure will decide to send or not an event on your webhook.

We're adding two new methods in our client to get and update user notification settings:

import { createClient } from '@liveblocks/client'const client = createClient({ ... })
const settings = await client.getNotificationSettings();// { email: { thread: true, ... }, slack: { thread: false, ... }, ... }console.log(settings);
const updatedSettings = await client.updateNotificationSettings({  email: {    thread: false,  }});

We're adding a new set of hooks to manage user notification settings.

You can either choose useNotificationSettings if you need to get the current user notification settings and update them at the same time:

// A suspense version of this hook is availableimport { useNotificationSettings } from "@liveblocks/react";
const [{ isLoading, error, settings }, updateSettings] =  useNotificationSettings();// { email: { thread: true, ... }, slack: { thread: false, ... }, ... }console.log(settings);
const onSave = () => {  updateSettings({    slack: {      textMention: true,    },  });};

Or you can choose useUpdateNotificationSettings if you just need to update the current user notification settings (e.g an unsubscribe button):

// A suspense version of this hook is availableimport { useUpdateNotificationSettings } from "@liveblocks/react";
const updateSettings = useUpdateNotificationSettings();
const onUnsubscribe = () => {  updateSettings({    slack: {      thread: false,    },  });};

Our Node.js client now exposes three new methods to manage user notification settings:

import { Liveblocks } from "@liveblocks/node";const liveblocks = new Liveblocks({ secret: "sk_xxx" });
const settings = await liveblocks.getNotificationSettings({ userId });// { email: { thread: true, ... }, slack: { thread: false, ... }, ... }console.log(settings);
const updatedSettings = await liveblocks.updateNotificationSettings({  userId,  data: {    teams: {      $fileUploaded: true,    },  },});await liveblocks.deleteNotificationSettings({ userId });

• Update the behavior of prepareThreadNotificationEmailAsHtml and prepareThreadNotificationEmailAsReact: the contents of previous emails data are now taken into account to avoid repeating mentions and replies that are still unread but have already been extracted in another email data.

Examples

• Added user notification settings to the Next.js Starter Kit.
• Updated all Yjs examples to use getYjsProviderForRoom.

Documentation

• New guide: What to check before enabling a new notification kind.
• Added info for new methods and hooks:
  • React: useNotificationSettings, useUpdateNotificationSettings.
  • JavaScript: getNotificationSettings, updateNotificationSettings.
  • Node.js: getNotificationSettings, updateNotificationSettings, deleteNotificationSettings.

v2.17.0

• Report a console error when a client attempts to send a WebSocket message that is >1 MB (which is not supported). Previously the client would silently fail in this scenario.

• Added a new client config option largeMessageStrategy to allow specifying the preferred strategy for dealing with messages that are too large to send over WebSockets. There now is a choice between:

  • default Don’t send anything, but log the error to the console.
  • split Split the large message up into smaller chunks (at the cost of sacrificing atomicity). Thank you @adam-subframe!
  • experimental-fallback-to-http Send the message over HTTP instead of WebSocket.

• Deprecated the unstable_fallbackToHTTP experimental flag (please set largeMessageStrategy="experimental-fallback-to-http" instead).

• Added <LiveblocksProvider largeMessageStrategy="..." /> prop to LiveblocksProvider. See above for possible options.

• Fix crash when a Composer is unmounted during its onComposerSubmit callback.

• Add new icons to <Icon.* />.

This release adds components and utilities to add an AI toolbar to your text editor, available in private beta.

• Add ai option to useLiveblocksExtension to enable (and configure) it.
• Add <AiToolbar /> component. (with <AiToolbar.Suggestion />, <AiToolbar.SuggestionsSeparator />, etc)
• Add default AI buttons in Toolbar and FloatingToolbar when the ai option is enabled.
• Add askAi Tiptap command to manually open the toolbar, it can also be invoked with a prompt to directly start the request when opening the toolbar. (e.g. editor.commands.askAi("Explain this text"))

v2.16.0

We've created new toolbar elements that allow you to import a default floating toolbar in Tiptap and Lexical. It's also possible to use these APIs to build custom or static toolbars. We've updated a number of our examples to show how to do this.

Our error listener APIs will now receive more errors in general, including errors from using Comments & Notifications. Previously, these would only receive room connection errors from Presence, Storage, or Yjs. For example, now when creation of a thread fails, deletion of a comment fails, marking a notification as read fails, etc.

// ❌ Before: required a RoomProvider and would only notify about errors for that room// ✅ Now: requires a LiveblocksProvider and will notify about errors for any roomuseErrorListener((err: LiveblocksError) => {  /* show toast, or notify Sentry, Datadog, etc */});

See the Upgrade Guide for 2.16 to learn how to adapt your code.

We now support filtering threads by absence of metadata as well in useThreads({ query }) (or useUserThreads_experimental({ query })). For example, you can now filter threads that do not have a color attribute set in their metadata:

useThreads({  query: {    // Filter any "pinned" threads that don't have a color set    metadata: {      pinned: true,      color: null, // ✨    },  },});

See the Upgrade Guide for 2.16 to learn how to adapt your code.

• Automatically refresh Comments and Notifications when the browser window regains focus.

The error listener APIs will now receive more errors in general, including errors from using Comments & Notifications. Previously, these would only receive room connection errors from Presence, Storage, or Yjs.

// 👌 Same as before, but might now also receive errors related to Comments & Notificationsroom.subscribe("error", (err) => { ... });

• Most of the icons used in the default components are now usable as <Icon.* /> via import { Icon } from "@liveblocks/react-ui".

• Add <Toolbar /> and <FloatingToolbar /> components to simplify building editor toolbars. They come with default controls out-of-the-box based on what the editor they’re attached to supports, but they’re also heavily extendable and customizable. Use inner components like <Toolbar.Toggle /> and <Toolbar.Separator /> to extend the defaults with your own actions, or start from scratch while customizing some of the defaults via <Toolbar.SectionInline /> or <Toolbar.BlockSelector /> for example.

• Add isTextFormatActive and isBlockNodeActive utilities.

Examples

• Updated Next.js Starter Kit to use the new FloatingToolbar.
• Updated many text editor examples to use the new FloatingToolbar:
  • Advanced collaborative text editor (Tiptap)`.
  • Collaborative text editor (Tiptap).
  • Collaborative text editor (Lexical).
  • Text editor comments (Tiptap).
  • Next.js Tiptap editor.
  • Next.js Tiptap editor.

Dashboard

• Allow rate limit configuration for webhook endpoints.
• Fix download comments attachments action in text editor view from room detail page.

v2.15.0

• Breaking: Drop support for React 17 (and 16). If you’re unable to upgrade React to 18 or higher, you can still continue to use Liveblocks 2.14.0, which is the last version to support React versions lower than 18.

• The published target for all Liveblocks packages is now ES2022 (up from ES2020). This should have a positive impact on your bundle size[*].

• Various internal refactorings and code cleanup.

[*] If you bundle for the browser, this should not be a problem, as all major browsers support ES2022. If however you're specifically targeting very old browsers (mostly IE), then you may need to configure your bundler (Webpack, rollup, esbuild, etc) to also down-compile code from dependencies inside node_modules for you, if you aren't already.
