Usage

Integration

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

app.module.ts
app.component.ts
app.component.html

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

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

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 groupObject!: CometChat.Group;
  ngOnInit(): void {
    CometChat.getGroup("guid").then((group: CometChat.Group) => {
      this.groupObject = 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 });
      }
    );
  }
}

<div class="fullwidth">
  <cometchat-join-group [group]="groupObject"></cometchat-join-group>
</div>

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. joinClick

The joinClick action is activated when you click the join Group button. This returns the join groups. You can override this action using the following code snippet.

app.component.ts
app.component.html

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 groupObject!: CometChat.Group;
  public handleJoinClick = (group: CometChat.Group, password: string) => {
    console.log("your custom join click action", group);
  };
  ngOnInit(): void {
    CometChat.getGroup("guid").then((group: CometChat.Group) => {
      this.groupObject = 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 });
      }
    );
  }
}

<div class="fullwidth">
  <cometchat-create-group
    [group]="groupObject"
    [joinClick]="handleJoinClick"
  ></cometchat-create-group>
</div>

2. errorCallback

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
app.component.html

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 groupObject!: CometChat.Group;
  public handleErrorCallback = () => {
    console.log("yoour custom error callback");
  };
  ngOnInit(): void {
    CometChat.getGroup("guid").then((group: CometChat.Group) => {
      this.groupObject = 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 });
      }
    );
  }
}

<div class="fullwidth">
  <cometchat-create-group
    [group]="groupObject"
    [errorCallback]="handleErrorCallback"
  ></cometchat-create-group>
</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. The Join Group component does not have any exposed filters.

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 Join Group component is as follows.

Event	Description
ccGroupMemberJoined	Triggers when the user joined a protected group successfully

TypeScript

import {CometChatGroupEvents} from "@cometchat/chat-uikit-angular";

this.ccGroupMemberJoined = CometChatGroupEvents.ccGroupMemberJoined.subscribe(
  (item: IGroupMemberJoined) => {
        // Your Code
  }
);

Removing CometChatGroupEvents Listener’s

TypeScript

this.ccGroupMemberJoined.unsubscribe();

Customization

To fit your app’s design requirements, you can customize the appearance of the Join 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.

1. JoinGroup Style

You can set the JoinGroupStyle to the Join Group Component to customize the styling.

app.component.ts
app.component.html

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit, JoinGroupStyle } 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 groupObject!: CometChat.Group;
  joinGroupStyle = new JoinGroupStyle({
    background: "#d1b2ed",

    joinButtonTextColor: "#000000",
    passwordInputTextColor: "#000000",
    titleTextColor: "#000000",
    passwordInputPlaceholderTextColor: "#000000",
  });
  ngOnInit(): void {
    CometChat.getGroup("guid").then((group: CometChat.Group) => {
      this.groupObject = 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 });
      }
    );
  }
}
