PubNub Chat Components for React

PubNub Chat Components for React are the fastest way to add chat features like direct and group messaging, typing indicators, reactions, without going through the complexity of low-level architecture of realtime networks.

• Reduced Implementation Time. Develop proof-of-concept and production ready apps faster using predefined components.
• Fast and Simple Extensibility. Add rich features like typing indicators, read receipts, reactions etc. without writing complex code.
• Flexible and Customizable Components. Customize component design and add custom components to extend functionality.
• High Scalability. Let PubNub take care of scaling and reliability as you grow your app.

Usage

Set up and use PubNub Chat Components for React to build your own chat application.

Set up PubNub account

1. Sign in or create an account to create an app on the Admin Portal and get the keys to use in your application.

2. When you create a new app, the first set of keys is generated automatically, but a single app can have as many keysets as you like. We recommend that you create separate keysets for production and test environments.

3. Some of the functionalities you might want to enable on your keyset depending on the use-case include Presence, Files, Storage & Playback (including correct Retention Period) and Objects (be sure to select a geographical region corresponding to most users of your application and to enable User, Channel and Membership Events). The moderated-chat sample requires these features are set in order to work with the moderation dashboard.

Run Sample Apps

Start by exploring our Sample Apps that are built using chat components. Follow the steps below to run the apps locally in your own environment.

1. Clone the repository.

1git clone https://github.com/pubnub/react-chat-components.git

2. Go to the samples folder.

1cd react-chat-components/samples

3. Install the dependencies.

1npm install

4. Follow steps from the PubNub Account section to create your own keys. Copy .env.example file as .env and paste your keys there.

1cp .env.example .env
2vi .env

5. Pre-populate the User and Channel Object metadata (required only for the moderated-chat sample).

1npm run setup

6. Run the application.

1npm start

Install and use components

1. Install the components and all required dependencies using npm.

1npm install --save pubnub pubnub-react @pubnub/react-chat-components

2. Import PubNub, PubNub React Provider and the components.

1import PubNub from "pubnub";
2import { PubNubProvider } from "pubnub-react";
3import {
4  Chat,
5  MessageList,
6  MessageInput,
7  ChannelList,
8  MemberList,
9} from "@pubnub/react-chat-components";

3. Create your PubNub client and rest of the configuration for the Chat provider.

1const pubnub = new PubNub({
2  publishKey: "myPublishKey",
3  subscribeKey: "mySubscribeKey",
4  uuid: "myUniqueUUID",
5});
6const currentChannel = "myCurrentChannel";
7const theme = "light";

4. Feed the PubNub Provider with your newly created client as with other PubNub React applications.

1const MyComponent = () => {
2  return <PubNubProvider client={pubnub}></PubNubProvider>;
3};

5. Place the components within the Chat state provider in any order that your app requires. Components can be tweaked later on using option properties and CSS variables.

1const MyComponent = () => {
2  return (
3    <PubNubProvider client={pubnub}>
4      <Chat {...{ currentChannel, theme }}>
5        <MessageList />
6        <MessageInput />
7      </Chat>
8    </PubNubProvider>
9  );
10};
