Groups

Overview

The Groups is a Component, showcasing an accessible list of all available groups. It provides an integral search functionality, allowing you to locate any specific groups swiftly and easily. For each group listed, the group name is displayed by default, in conjunction with the group icon when available. Additionally, it provides a useful feature by displaying the number of members in each group as a subtitle, offering valuable context about group size and activity level.

The Groups 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 Group 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 Groups component into your Application.

app.module.ts

import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { CometChatGroups } from "@cometchat/chat-uikit-angular";
import { AppComponent } from "./app.component";

@NgModule({
  imports: [BrowserModule, CometChatGroups],
  declarations: [AppComponent],
  providers: [],
  bootstrap: [AppComponent],
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
})
export class AppModule {}

app.component.ts

import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',

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 the group object along with the boolean flag selected to indicate if the group was selected or unselected.

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.component.ts

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import { SelectionMode } from '@cometchat/uikit-resources';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  public selectionMode: SelectionMode = SelectionMode.multiple;
  public handleOnSelectGroup = (group: CometChat.Group, selected: boolean): void => {
    console.log("Custom on select action", group, selected);
  };
  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }

  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
  <cometchat-groups
    [selectionMode]="selectionMode"
    [onSelect]="handleOnSelectGroup"
  ></cometchat-groups>
</div>

2. onItemClick

The onItemClick event is activated when you click on the Group List 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.

app.component.ts

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  public handleOnItemClickGroup = (group: CometChat.Group)=> {
    console.log("your custom on item click action", group);
  };
  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }

  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
  <cometchat-groups [onItemClick]="handleOnItemClickGroup"></cometchat-groups>
</div>

3. onError

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

app.component.ts

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  public handleOnError = (error: CometChat.CometChatException) => {
    console.log("your custom on error action", error);
  };
  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }

  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
  <cometchat-groups [onError]="handleOnError"></cometchat-groups>
</div>

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. GroupsRequestBuilder

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

Methods	Type	Description
setLimit	number	sets the number groups that can be fetched in a single request, suitable for pagination
setSearchKeyword	String	used for fetching groups matching the passed string
joinedOnly	boolean	to fetch only joined groups.
setTags	Array<String>	used for fetching groups containing the passed tags
withTags	boolean	used to fetch tags data along with the list of groups

Example

In the example below, we are applying a filter to the Group List based on only joined groups and setting the limit to two.

app.component.ts

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  groupsRequestBuilder = new CometChat.GroupsRequestBuilder().setLimit(2).joinedOnly(true);
  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }

  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
  <cometchat-groups
    [groupsRequestBuilder]="groupsRequestBuilder"
  ></cometchat-groups>
</div>

---

2. SearchRequestBuilder

The SearchRequestBuilder uses GroupsRequestBuilder enables you to filter and customize the search list based on available parameters in GroupsRequestBuilder. This feature allows you to keep uniformity between the displayed Groups List and searched Group List.

Example

app.component.ts

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import "@cometchat/uikit-elements";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  searchRequestBuilder = new CometChat.GroupsRequestBuilder().setLimit(4).setSearchKeyword("your search keyword")
  constructor(private themeService:CometChatThemeService) {
    themeService.theme.palette.setMode("light")
    themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
  }

  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
  <cometchat-groups
    [searchRequestBuilder]="searchRequestBuilder"
  ></cometchat-groups>
</div>

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 Groups you have to add corresponding listeners by using CometChatGroupEvents

The Groups component does not produce any events directly.

---

Customization

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