Users

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:

ComponentsDescription
CometChatLista reusable container component having title, search box, customisable background and a List View
CometChatListItema 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.

UsersDemo.tsx
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.

UsersDemo.tsx
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.

UsersDemo.tsx
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.

UsersDemo.tsx
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

MethodsTypeDescription
setLimitnumbersets the number users that can be fetched in a single request, suitable for pagination
setSearchKeywordStringused for fetching users matching the passed string
hideBlockedUsersbooleanused for fetching all those users who are not blocked by the logged in user
friendsOnlybooleanused for fetching only those users in which logged in user is a member
setRolesList<String>used for fetching users containing the passed tags
setTagsList<String>used for fetching users containing the passed tags
withTagsbooleanused for fetching users containing tags
setStatusStringused for fetching users by their status online or offline
setUIDsList<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.

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

function UsersDemo() {
  return (
    <CometChatUsers
      usersRequestBuilder={new CometChat.UsersRequestBuilder()
        .friendsOnly(true)
        .setLimit(2)}
    />
  );
}

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

UsersDemo.tsx
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 Style you can customize the look and feel of the component in your app, These parameters typically control elements such as the color, size, shape, and fonts used within the component.

1. Users Style​

You can set the UsersStyle to the Users Component to customize the styling.
