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.

---

Usage

Integration

To use Users in your component, use the following code snippet:

App.tsx

import { CometChatUsers } from "@cometchat/chat-uikit-react-native";
//code
return <CometChatUsers />;

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.

onItemPress

Function invoked when a user item is clicked, typically used to open a user profile or chat screen.

App.tsx

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

const onPressHandler = (user: CometChat.User) => {
  //code
};

return <CometChatUsers onItemPress={onPressHandler} />;

---

onItemLongPress

Function executed when a user item is long-pressed, allowing additional actions like delete or block.

App.tsx

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

const onLongPressHandler = (user: CometChat.User) => {
  //code
};

return <CometChatUsers onItemLongPress={onLongPressHandler} />;

---

onBack

onBack is triggered when you press the back button in the app bar. It has a predefined behavior; when clicked, it navigates to the previous activity. However, you can override this action using the following code snippet.

App.tsx

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

const onBackHandler = () => {
  //code
};

return <CometChatUsers hideBackButton={false} onBack={onBackHandler} />;

---

onSelection

Called when a item from the fetched list is selected, useful for multi-selection features.

App.tsx

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

const onSelectionHandler = (selection: Array<CometChat.User>) => {
  //code
};

return (
  <CometChatUsers selectionMode={"single"} onSelection={onSelectionHandler} />
);

---

OnError

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

App.tsx

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

const onErrorHandler = (error: CometChat.CometChatException) => {
  console.log("Error");
};

return <CometChatUsers onError={onErrorHandler} />;

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	bool	used for fetching all those users who are not blocked by the logged in user
friendsOnly	bool	used for fetching only those users in which logged in user is a member
setRoles	Array<string>	used for fetching users containing the passed tags
setTags	Array<string>	used for fetching users containing the passed tags
withTags	bool	used for fetching users containing tags
setUserStatus	string	used for fetching users by their status online or offline
setUIDs	Array<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.

App.tsx

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

function App(): React.JSX.Element {
  const usersRequestBuilder = new CometChat.UsersRequestBuilder()
    .setLimit(5)
    .friendsOnly(true);

  return <CometChatUsers usersRequestBuilder={usersRequestBuilder} />;
}

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

App.tsx`

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

function App(): React.JSX.Element {
  const usersRequestBuilder = new CometChat.UsersRequestBuilder()
    .setLimit(5)
    .setSearchKeyword("Alice");

  return <CometChatUsers searchRequestBuilder={usersRequestBuilder} />;
}

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 CometChatUIEventHandler.addUserListener

Events	Description
ccUserBlocked	This will get triggered when the logged in user blocks another user
ccUserUnblocked	This will get triggered when the logged in user unblocks another user

Adding Listeners

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

CometChatUIEventHandler.addUserListener("USER_LISTENER_ID", {
  ccUserBlocked: ({ item }) => {
    //code
  },
});

CometChatUIEventHandler.addUserListener("USER_LISTENER_ID", {
  ccUserUnblocked: ({ item }) => {
    //code
  },
});

Customization

To fit your app's design requirements, you can customize the appearance of the User 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.

You can set the styling object to the CometChatUsers Component to customize the styling.

App.tsx

import { CometChatUsers } from "@cometchat/chat-uikit-react-native";
//code
return (
  <CometChatUsers
    style={{
      titleStyle: {
        color: "#FBAA75",
      },
      titleSeparatorStyle: {
        borderBottomColor: "#FBAA75",
      },
      itemStyle: {
        avatarStyle: {
          containerStyle: {
            borderRadius: 8,
            backgroundColor: "#FBAA75",
          },
          imageStyle: {
            borderRadius: 8,
          },
        },
      },
    }}
  ></CometChatUsers>
);

---

LoadingView

This method allows developers to set a custom loading view that is displayed when data is being fetched or loaded within the component. Instead of using a default loading spinner, a custom animation, progress bar, or branded loading screen can be displayed.

Use cases:

• Showing a skeleton loader for users while data loads
• Displaying a custom progress indicator with branding
• Providing an animated loading experience for a more engaging UI

App.tsx

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

• Providing a button to start a new user

App.tsx

import { CometChatUsers } from "@cometchat/chat-uikit-react-native";
//code
const getEmptyView = (): JSX.Element => {
  //your custom loading view
  //return jsx;
};
return <CometChatUsers EmptyView={getEmptyView}></CometChatUsers>;

---

ErrorView

Defines a custom error state view that appears when an issue occurs while loading users or messages. This enhances the user experience by displaying friendly error messages instead of generic system errors.

Common use cases:

• Showing "Something went wrong. Please try again." with a retry button
• Displaying a connection issue message if the user is offline
• Providing troubleshooting steps for the error

App.tsx

import { CometChatUsers } from "@cometchat/chat-uikit-react-native";
//code
const getErrorView = (): JSX.Element => {
  //your custom loading view
  //return jsx;
};
return <CometChatUsers ErrorView={getErrorView}></CometChatUsers>;

---

LeadingView
