Add Members - CometChat Docs

Overview

CometChatAddMembers is a Component that allows administrators or group owners to add new members to a specific group. It enables administrators or group owners to extend the membership of a group by adding new users to participate in the group’s discussions and activities. By utilising this feature, administrators can manage group membership, and control access to group content. The administrator can select the desired users to be added to the group. This can be done by searching for specific users, selecting from a list of available users. The selected users will receive notifications to join the group.

Usage

Integration

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

App.tsx

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

function App(): React.JSX.Element {
  const [group, setGroup] = useState<CometChat.Group | undefined>(undefined);

  const getGroup = async () => {
    const group = await CometChat.getGroup("guid");
    setGroup(group);
  };

  useEffect(() => {
    //login
    getGroup();
  });

  return (
    <>{group && <CometChatAddMembers group={group}></CometChatAddMembers>}</>
  );
}

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. onSelection

The onSelection 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.

App.tsx

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

function App(): React.JSX.Element {
  const [group, setGroup] = useState<CometChat.Group | undefined>(undefined);

  const getGroup = async () => {
    const group = await CometChat.getGroup("guid");
    setGroup(group);
  };

  useEffect(() => {
    //login
    getGroup();
  });

  const onSelectionHandler = (list: CometChat.User[]) => {
    //code
  };

  return (
    <>
      {group && (
        <CometChatAddMembers
          group={group}
          onSelection={onSelectionHandler}
        ></CometChatAddMembers>
      )}
    </>
  );
}

2. OnBack

OnBack is triggered when you click on the back button of the Add Members component. You can override this action using the following code snippet.

App.tsx

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

function App(): React.JSX.Element {
  const [group, setGroup] = useState<CometChat.Group | undefined>(undefined);

  const getGroup = async () => {
    const group = await CometChat.getGroup("guid");
    setGroup(group);
  };

  useEffect(() => {
    //login
    getGroup();
  });

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

  return (
    <>
      {group && (
        <CometChatAddMembers
          group={group}
          onBack={onBackHandler}
        ></CometChatAddMembers>
      )}
    </>
  );
}

3. onError

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

App.tsx

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

function App(): React.JSX.Element {
  const [group, setGroup] = useState<CometChat.Group | undefined>(undefined);

  const getGroup = async () => {
    const group = await CometChat.getGroup("guid");
    setGroup(group);
  };

  useEffect(() => {
    //login
    getGroup();
  });

  const onErrorHandler = (error: CometChat.CometChatException) => {
    //code
  };

  return (
    <>
      {group && (
        <CometChatAddMembers
          group={group}
          onError={onErrorHandler}
        ></CometChatAddMembers>
      )}
    </>
  );
}

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. UsersRequestBuilder

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

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	Array<string>	used for fetching users containing the passed tags
setTags	Array<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	Array<string>	used for fetching users containing the passed users

Example In the example below, we are applying a filter to the UserList by setting the limit to four and sorting the lists by their name.

App.tsx

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

function App(): React.JSX.Element {
  const [group, setGroup] = useState<CometChat.Group | undefined>(undefined);

  const getGroup = async () => {
    const group = await CometChat.getGroup("guid");
    setGroup(group);
  };

  useEffect(() => {
    //login
    getGroup();
  });

  const usersRequestBuilder = new CometChat.UsersRequestBuilder()
    .setLimit(4)
    .sortBy("name");

  return (
    <>
      {group && (
        <CometChatAddMembers
          group={group}
          usersRequestBuilder={usersRequestBuilder}
        ></CometChatAddMembers>
      )}
    </>
  );
}

2. SearchRequestBuilder

The SearchRequestBuilder uses UserRequestBuilder enables you to filter and customize the search list based on available parameters in UserRequestBuilder. Example

App.tsx

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

function App(): React.JSX.Element {
  const [group, setGroup] = useState<CometChat.Group | undefined>(undefined);

  const getGroup = async () => {
    const group = await CometChat.getGroup("guid");
    setGroup(group);
  };

  useEffect(() => {
    //login
    getGroup();
  });

  const searchRequestBuilder = new CometChat.UsersRequestBuilder()
    .setLimit(100)
    .setSearchKeyword("Alice");

  return (
    <>
      {group && (
        <CometChatAddMembers
          group={group}
          searchRequestBuilder={searchRequestBuilder}
        ></CometChatAddMembers>
      )}
    </>
  );
}

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. Events emitted by the Add Members component is as follows.

Event	Description
ccGroupMemberAdded	Triggers when a user added to a group successfully

Adding Listeners

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

CometChatUIEventHandler.addGroupListener("GROUP_LISTENER_ID", {
  ccGroupMemberAdded: ({ message }: { message: CometChat.BaseMessage }) => {
    //code
  },
});

Removing Listeners

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

CometChatUIEventHandler.removeGroupListener("GROUP_LISTENER_ID");
