At the moment, only available in Portuguese, but English version is coming soon. Reach out to us on Twitter if you want to push us to get it done sooner :)

First run

Right after creating a project and then npm install, it should be ready to go. Just move into your project's folder and execute the normal tns command to run any app:

cd your-project-name
npm i
tns run

Alternatively you can target any specifc platform:

tns run android

tns run ios

That's pretty much what you should expect to see for the initial screen:

- Screenshot 1: Chats tab (iOS / Android)

And that's the chat screen upon clicking on any chat item in the previous screen:

- Screenshot 2: Chat screen (iOS / Android)

Removing initial data

You might want to remove all the dummy data as well as some boilerplate code. The content shown relies upon the service core/chats.services.ts inside your app folder. Just replace the content returned there with what you need.

Emptying chats.services.ts

import { Injectable } from '@angular/core';

import { Chat } from './models/chat.model';
import { Message } from './models/message.model';

@Injectable()
export class ChatsService {
  get chats(): Chat[] {
    return [];
  }
  getMessages(chat: Chat): Message[] {
    return [];
  }
}

Another advisable tweak is removing the line which slices the list of messages in the selected chat to get only a chunck of initial 50 ones. The reason for that is just to illustrate that not all messages should appear on landing on that screen, but we wouldn't like to sound too opinionated at this point telling you how to fetch and show your own data.

Replace the slice command on messages-area.component.ts

export class MessagesAreaComponent implements OnInit {
  // ...
  ngOnInit() {
-    this.messages = this.messages.slice(0, 50);
+    // your own code
  }
  // ...
}
