sendbird-uikit

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.

Installation

npm i @sendbird/uikit-react

For typescript projects, add node_modules/@sendbird/uikit-react/index.d.ts to your include section in tsconfig file to get type definitions

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

Prerequisites

You need to install:

• nodejs 16 LTS https://nodejs.org/en/download/
• npm 8 or above

Caveats

• We tried development on Mac OS / Linux systems. You might encounter problems in running npm run build in Windows machines
• If you use node.js >= 17 and see ERR_OSSL_EVP_UNSUPPORTED error on any run cmd, try to set export NODE_OPTIONS=--openssl-legacy-provider in the terminal

Development

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

Make a copy of .env.example and save it as .env
Set your appId STORYBOOK_APP_ID
npm install
npm run storybook

npm run generate-component generates a UI component skeleton in src/ui

• 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

Build

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

We have both esm and commonjs output

npm run build

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

Running the tests

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

npm run test

Lint

npm run lint

• .eslintrc.json lints ts files and .eslintrc.js lints js files

Typescript

• We are trying to progressively move our source code to typescript - which means older JS code and newly written TS code will coxist while we migrate older JS code to TS
• .eslintrc.json lints ts files and .eslintrc.js lints js files
• Type definition file can be src/index.d.ts which will be copied to /release directory

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'),
    },
  },
};

To read more: https://webpack.js.org/configuration/resolve/#resolvefallback

Creating/exporting new components

1. Define your component inside './src'
2. Add the following line to './src/index.js' export NewComponent from './src/location/of/NewComponent';
3. Add the following line to './exports.js' NewComponent: 'src/location/of/NewComponent',
