Sendbird UIKit React - v3.14.3


Platform React Language TypeScript

React based UI kit based on sendbird javascript SDK

We are introducing a new version of the Sendbird Chat UIKit. Version 3 features a new modular architecture with more granular components that give you enhanced flexibility to customize your web and mobile apps. Check out our migration guides.


yarn add @sendbird/uikit-react or if you're using npm npm i @sendbird/uikit-react

Getting Started

With Sendbird UI Kit React, we export these components: (See src/index.jsx)

  • SendBirdProvider - The context provider for SDK component

  • useSendbirdStateContext - Hook to access SendBirdProvider context

  • sendBirdSelectors - A bunch of useful selectors that can be used along with useSendbirdStateContext

  • Channel - A UI Component where conversations happen

  • ChannelList - A ChannelList UI component

  • ChannelSettings - A component to handle the settings of a given channel

  • MessageSearch - To search for a message from a Channel

  • OpenChannel - A UI Component where open channel conversations happen

  • OpenChannelSettings - A component to handle the settings of a given channel And many more...

  • App - is a full fledged app(group channel) component made by combining the above components so that you dont have to combine all the above components by hand. Also it can be used as an example for composing components to build a chat UI

Note 1: Dont forget to import the stylesheet from the repo too Note 2: Name of some components are different from the directories they are in(example -> Channel component is from Conversation component). Please keep that in mind


You need to install:

  • nodejs 18>=
  • npm 9>= or yarn 3>=


We use storybook for development and rollup for building the npm distribution(bundled JS file) Make sure you have nodejs and yarn(or npm) installed and run

Make a copy of .env.example and save it as .env Set your appId STORYBOOK_APP_ID

yarn install
yarn storybook


npm install
npm run storybook
  • By default, storybook opens in http://localhost:6006/
  • Smart Components such as ChannelList, Channel, ChannelSetting, App can be found under OTHERS
  • Dumb components such as inputs, buttons etc can be found under OTHERS/UI Components in storybook sidebar
  • Overridden storybook configs can be found in: ./storybook


We use Husky for githooks

To enable Husky in local, run: yarn husky install or npx husky install


We use RollupJS for building the production bundle script that you want to use inside your applications.

We have both ESM and CJS output

yarn build


npm run build

The bundled JS code can be found in ./dist The CSS is in ./dist/dist/index.css


  • We tried development on Mac OS / Linux systems. You might encounter problems in running yarn build or npm run build in Windows machines

Running the tests

We have implemented tests for dumb ui components only. Technologies used: Jest and testing-library

yarn test


npm run test


yarn lint


npm run lint
  • .eslintrc.json lints ts files and .eslintrc.js lints js files

Webpack 5

Webpack 5 removes stream and buffer componets from default polyfill To enable these, install buffer and stream and then add the following to webpack.cofig.js

module.exports = {
resolve: {
fallback: {
buffer: require.resolve('buffer'),
stream: require.resolve('stream-browserify'),

Creating/Exporting New Components

  1. Define your component inside ./src.
  2. Add the following line to ./src/index.ts:
    export { default as NewComponent } from './src/location/of/NewComponent';
    • Will be imported as: import { NewComponent } from '@sendbird/uikit-react';
    • We don't do this anymore for new components; we prefer fine-grained exports (as in step 3).
  3. Add the following line to ./rollup.module-exports.js:
    'NewComponent/SubComponent': 'location/of/NewComponent/SubComponent',
    • This component can be imported by the consumer as: import SubComponent from '@sendbird/uikit-react/NewComponent/SubComponent';

Scaffolding New Components

  1. Use yarn run generate-component to generate a UI component in src/ui. It uses Plop.js to generate the component.
  2. It can also be used to generate reducers.
  3. Plop templates are found in here.



We use lamejs for converting audio formats It is a fast mp3 encoder written in JavaScript. The original repo is:
