Users - CometChat Docs

Overview

The Users is a Component, showcasing an accessible list of all available users. It provides an integral search functionality, allowing you to locate any specific user swiftly and easily. For each user listed, the widget displays the user’s name by default, in conjunction with their avatar when available. Furthermore, it includes a status indicator, visually informing you whether a user is currently online or offline.

The Users component is composed of the following BaseComponents:

Components	Description
CometChatList	A reusable container component having title, search box, customisable background and a list view.
CometChatListItem	A component that renders data obtained from a User object on a Tile having a title, subtitle, leading and trailing view.

Usage

Integration

The following code snippet illustrates how you can directly incorporate the Users component into your Application.

import { CometChatUsers } from "@cometchat/chat-uikit-react";

function UsersDemo() {
  return <CometChatUsers />;
}

export default UsersDemo;

Actions

Actions dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.

1. onSelect

The onSelect action is activated when you select the done icon while in selection mode. This returns a list of all the users that you have selected. This action does not come with any predefined behavior. However, you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.

import { CometChatUsers, SelectionMode } from "@cometchat/chat-uikit-react";

function UsersDemo() {
  function handleOnSelect(users: CometChat.User, selected: boolean): void {
    console.log(users);
    //your custom onSelect actions
  }

  return (
    <CometChatUsers
      selectionMode={SelectionMode.multiple}
      onSelect={handleOnSelect}
    />
  );
}

export default UsersDemo;

2. onItemClick

The OnItemClick event is activated when you click on the UserList item. This action does not come with any predefined behavior. However, you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.

import { CometChatUsers } from "@cometchat/chat-uikit-react";

function UsersDemo() {
  function handleOnItemClick(user: CometChat.User): void {
    console.log(user, "your custom on item click action");
  }
  return <CometChatUsers onItemClick={handleOnItemClick} />;
}

export default UsersDemo;

3. onEmpty

This action allows you to specify a callback function to be executed when a certain condition, typically the absence of data or content, is met within the component or element.

import { CometChatUsers } from "@cometchat/chat-uikit-react";

function UsersDemo() {
  function handleOnEmpty(): void {
    console.log("your custom on Empty action");
  }
  return <CometChatUsers onEmpty={handleOnEmpty} />;
}

export default UsersDemo;

4. onError

This action doesn’t change the behavior of the component but rather listens for any errors that occur in the User component.

import { CometChatUsers } from "@cometchat/chat-uikit-react";

function UsersDemo() {
  const handleOnError = (error: CometChat.CometChatException) => {
    console.log("Your custom on error actions");
  };
  return <CometChatUsers onError={handleOnError} />;
}

export default UsersDemo;

Filters

Filters allow you to customize the data displayed in a list within a Component. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of Chat SDK.

1. UserRequestBuilder

The UserRequestBuilder enables you to filter and customize the user list based on available parameters in UserRequestBuilder. This feature allows you to create more specific and targeted queries when fetching users. The following are the parameters available in UserRequestBuilder

Methods	Type	Description
setLimit	number	sets the number users that can be fetched in a single request, suitable for pagination
setSearchKeyword	String	used for fetching users matching the passed string
hideBlockedUsers	boolean	used for fetching all those users who are not blocked by the logged in user
friendsOnly	boolean	used for fetching only those users in which logged in user is a member
setRoles	List<String>	used for fetching users containing the passed tags
setTags	List<String>	used for fetching users containing the passed tags
withTags	boolean	used for fetching users containing tags
setStatus	String	used for fetching users by their status online or offline
setUIDs	List<String>	used for fetching users containing the passed users

Example In the example below, we are applying a filter to the UserList based on Friends.

import { CometChat } from "@cometchat/chat-sdk-javascript";
import { CometChatUsers } from "@cometchat/chat-uikit-react";

function UsersDemo() {
  return (
    <CometChatUsers
      usersRequestBuilder={new CometChat.UsersRequestBuilder().friendsOnly(
        true
      )}
    />
  );
}

export default UsersDemo;

2. SearchRequestBuilder

The SearchRequestBuilder uses UserRequestBuilder enables you to filter and customize the search list based on available parameters in UserRequestBuilder. This feature allows you to keep uniformity between the displayed UserList and searched UserList. Example

import { CometChat } from "@cometchat/chat-sdk-javascript";
import { CometChatUsers } from "@cometchat/chat-uikit-react";

function UsersDemo() {
  return (
    <CometChatUsers
      searchRequestBuilder={new CometChat.UsersRequestBuilder().setSearchKeyword(
        "**"
      )}
    />
  );
}

export default UsersDemo;

Events

Events are emitted by a Component. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed. To handle events supported by Users you have to add corresponding listeners by using CometChatUserEvents The Users component does not produce any events directly.

Customization

To fit your app’s design requirements, you can customize the appearance of the Users component. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.

Style

Using CSS you can customize the look and feel of the component in your app like the color, size, shape, and fonts. Example

import { CometChatUsers } from "@cometchat/chat-uikit-react";

function UsersDemo() {
  return <CometChatUsers showSectionHeader={false} />;
}

export default UsersDemo;

Functionality

These are a set of small functional customizations that allow you to fine-tune the overall experience of the component. With these, you can change text, set custom icons, and toggle the visibility of UI elements.

import { CometChatUsers, TitleAlignment } from "@cometchat/chat-uikit-react";

function UsersDemo() {
  return (
    <CometChatUsers
      title="Your Custom Title"
      showSectionHeader={true}
      tileAlignment={TitleAlignment.center}
    />
  );
}

export default UsersDemo;

Below is a list of customizations along with corresponding code snippets
