Liveblocks best practices
When to use this skill
Use this skill when implementing features using any Liveblocks packages, for
example @liveblocks/react
or @liveblocks/node. This
could be related to features like realtime multiplayer, commenting,
notifications, cursors, avatar stacks, AI, and more. This also includes
technologies like Liveblocks Storage, Yjs, Tiptap, BlockNote, Lexical, React
Flow, tldraw, and more.
Quick reference
A number of reference files are available in the references/ directory. You
must read the list below, and load relevant files as needed. For example,
add-user-information is available in the references/add-user-information.md
file.
References
add-user-information: Add user information to your application, such as
name, avatar, color, and more. Users will no longer be anonymous. Useful for
displaying user info in comments, comments mention suggestions, notifications,
cursors, avatar stacks.
ai-as-a-collaborator: Use agentic workflows to allow AI to collaborate like
a human inside your Liveblocks application.
ai-chats-with-tools-knowledge-components: Set up and troubleshoot chats with
RAG, knowledge, custom components, tool calling, custom models. Different to
AI as a collaborator, as it is NOT workflow based.
auth-endpoint-callback: Use a callback function to authenticate users,
instead of passing a string to authEndpoint. Useful for passing custom
headers to your back end, and for preventing automatic reconnection when the
token is invalid.
authenticating-with-access-tokens: Alternative method for authenticating
users with their ID and info, best for very simple permissions.
authenticating-with-id-tokens: Recommended method for authenticating users
with their ID and info, best for complex permissions.
avoid-hitting-user-limit-in-rooms: How to avoid rooms filling up with users.
compartmentalize-resources-with-organizations: Use organizations to create
workspaces/tenants and compartmentalize resources, such as rooms,
notifications, comment threads, and more. You can filter by organization when
listing rooms and more.
create-custom-comment-composer: Build your own commenting composer (advanced
use cases only).
create-custom-realtime-multiplayer: Use Liveblocks Storage to build fully
custom conflict-resolved multiplayer apps, like Figma, Pitch, Spline. Helpful
for one-off realtime features too, like simple properties in a document.
create-custom-text-editor-toolbar: Set up a styled toolbar, static or
floating next to your selection, in Tiptap and Lexical.
create-rooms-manually: Always create rooms yourself in production
applications, setting permissions, organization, metadata.
customize-thread-components: Use slots to customize comments inside of
threads, and their different parts.
dark-mode-styles: You can import CSS styling for dark mode themes.
develop-and-test-locally: Set up a local dev server, and use it for
Continuous Integration (CI) and End-to-End (E2E) testing. Connect to your app
not online.
devtools-extension: Inspect Liveblocks Storage, Yjs, presence, events, and
connected users with DevTools extensions for Chrome, Firefox, Edge.

Liveblocks packages
Always check if we provide a package for your technology. For example, if you're
using React Flow, you should use @liveblocks/react-flow.
@liveblocks/client: JavaScript client. Can use with any framework, e.g.
Vue, Svelte, vanilla JS.
@liveblocks/react: React client. Contains hooks and components..
@liveblocks/react-ui: Pre-built React UI components and primitives.
@liveblocks/react for data and hooks.
@liveblocks/react-tiptap: Collaborative Tiptap integration for React.
@liveblocks/react-blocknote: Collaborative BlockNote integration for
React.
@liveblocks/react-lexical: Collaborative Lexical integration for React.
@liveblocks/node-lexical: Server-side Lexical utilities for Node.js.
@liveblocks/node-prosemirror: Server-side ProseMirror utilities For
Node.js. Also works with Tiptap and BlockNote.
@liveblocks/react-flow: Multiplayer React Flow.
@liveblocks/yjs: Yjs provider backed by Liveblocks rooms.
@liveblocks/redux: Sync Liveblocks room state with a Redux store.
@liveblocks/zustand: Sync Liveblocks room state with Zustand.
@liveblocks/node: Node.js server SDK. Use for auth and lots more.
@liveblocks/emails: Build notification emails more easily.
@liveblocks/chat-sdk-adapter: Make multi-platform (Liveblocks, Slack,
Discord, etc.) chat bots.
Python SDK: Python server SDK. Use for auth and lots more.
REST API: HTTP API. Use for auth and lots more.
If a technology is not listed here
If the users want to set up a new technology, first check the following
resources to see if a package exists:
edit-component-text-strings: Override strings in default components, such as
button values, tooltip text, error text, more. Also helpful for setting other
languages.
exhaustive-deps-with-usemutation: Prevent and fix stale-closure bugs with
useMutation by configuring the react-hooks/exhaustive-deps ESLint rule.
handling-connection-errors: Handle problems joining rooms because of
permissions, authentication, changed room IDs.
handling-full-rooms: Handle problems caused by joining full rooms.
handling-hook-and-component-errors: Handle errors caused by hooks and
pre-built components.
handling-unstable-connections: Implement fallbacks and error messages when
users have poor network conditions.
log-out-of-liveblocks: Rarely useful, but helpful in specific SPA situations
where you cannot navigate the page to log out.
multiplayer-react-flow: Use the Liveblocks React Flow package to create
multiplayer diagrams with cursors and more.
multiple-text-editors: Add multiple Tiptap or BlockNote editors to the same
page. Optionally use Storage to hold their field IDs.
offline-support-in-text-editors: Give your text editors the illusion of a
quicker load time.
override-css-variables: Add custom styles to the default components by
overriding Liveblocks CSS variables.
performant-others-and-presence: Prevent unnecessary presence renders by
using useOtherConnectionIds, useOthersMapped, useOther, and shallow to
update components only when necessary.
performant-storage-with-selectors: Prevent unnecessary storage renders by
using useStorage selectors and shallow.
prevent-unsaved-changes-being-lost: Stop losing unsynched or unsaved
changes.
primitive-component-parts: Use primitives to create custom components or to
merge components from your design system into Liveblocks UI.
remove-liveblocks-branding: A Liveblocks logo badge appears in the bottom
right of the screen, this is how to remove it.
rendering-error-components: Use ErrorBoundary to structure your app with
error fallbacks.
rendering-loading-components: Use ClientSideSuspense to performantly
structure your app with loading skeletons and spinners.
send-comment-notification-emails: Send email notifications to users when
they have unread comments. These comments are sent via webhooks, and are
triggered when a user is mentioned, or has participated in a thread.
smoother-realtime-updates: Make presence and storage run at a higher frame
rate, appearing more smooth. Using this option, updates can be received more
frequently.
suspense-vs-regular-hooks: You must read this when using any Liveblocks
hooks. React suspense uses ErrorBoundary and ClientSideSuspense
components. Regular hooks use { error, isLoading } values.
trigger-custom-notifications: Trigger any kind of notification in your
inbox, even those unrelated to commenting.
type-liveblocks-correctly: Always use TypeScript to type Liveblocks where
available. Presence, others, user info, storage, metadata, room info,
notifications activities, can all be automatically typed.
url-params-in-room-id: Use URL params in room IDs to create rooms, and
incorporate document titles in the URL.
utility-components: Import a ready-made emoji picker, or human-readable
timestamps, durations, file sizes.
yjs-best-practices: YKeyValue, subdocuments, V2 encoding, double imports,
getYjsProviderForRoom. NOT relevant if you're using Tiptap, BlockNote, or
Lexical.
z-index-issues: Fix z-index problems by targeting portaled elements.
