Upgrading From V3

Upgrading from v3.x to v4 is fairly simple. Below are the major changes that are released as a part of CometChat v4: Please follow the setup instructions to upgrade to latest version of V4 before proceeding further

Dependency Change

Chat SDK

JavaScript

# Remove v3 packages
npm uninstall @cometchat-pro/chat @cometchat-pro/calls

# Install v4 packages

npm i @cometchat/chat-sdk-javascript
npm i @cometchat/calls-sdk-javascript

Update Import Statements

Find and replace all import statements across your project:

SDK	v3 Import	v4 Import
Chat SDK	`import { CometChat } from '@cometchat-pro/chat'`	`import { CometChat } from '@cometchat/chat-sdk-javascript'`
Calls SDK	`import { CometChatCalls } from '@cometchat-pro/calls'`	`import { CometChatCalls } from '@cometchat/calls-sdk-javascript'`

// v4 Chat SDK
import { CometChat } from '@cometchat/chat-sdk-javascript';

// v4 Calls SDK
import { CometChatCalls } from '@cometchat/calls-sdk-javascript';

The API methods, class names, and listener interfaces are unchanged between v3 and v4. Once you update the packages and imports, your existing code should work without further modifications.
