# 10.7: Adding Conversations to MemberDetailComponent

Now, we'll work on adding the message threads to the `MemberDetailComponent`

## Adding getMessageThread() to UserService

We'll start by adding a new method `getMessageThread()` to the `UserService`:

```typescript
getMessageThread(id: number, recipientId: number) {
    return this._http.get<Message[]>(this.baseUrl + 'users/' + id + '/messages/thread/' + recipientId);
}
```

## Add MemberMessagesComponent

We'll add a new component to display the conversations.

```
ng g c members/member-messages --no-spec
```

Verify that it was added correctly to `app.module.ts`.

Update `member-messages.component.ts` to the following:

```typescript
export class MemberMessagesComponent implements OnInit {
  @Input() userId: number;
  messages: Message[];

  constructor(private _userService: UserService,
              private _authService: AuthService,
              private _alertify: AlertifyService) { }

  ngOnInit() {
    this.loadMessages();
  }

  loadMessages() {
    this._userService.getMessageThread(this._authService.decodedToken.nameid, this.userId).subscribe(messages => {
      this.messages = messages;
    }, error => {
      this._alertify.error(error);
    });
  }

}
```

This is again very similar to what we've been doing. We do have an `Input()` property for the `userId` that we'll get from the `MemberDetailComponent`.

In `member-detail.component.html`, add the component and pass along the `userId`:

## Adding MemberMessages Template

And, in `member-messages.component.scss`:

```css
.chat {
    list-style: none;
    margin: 0;
    padding: 0;
}

.chat li {
    margin-bottom: 10px;
    padding-bottom: 10px;
    border-bottom: 1px dotted #b3a9a9;
}

.rounded-circle {
    height: 50px;
    width: 50px;
}

.card-body {
    overflow-y: scroll;
    height: 400px;
}

.read {
    color: #60AB15;
}

.unread {
    color: #D9514E;
}
```

## Navigating Directly to Messages Tab

We'd like to be able to navigate from the `Messages` component to the `MemberDetail` component and have the `Messages` tab be open instead of the `About` tab. We'd also like to open the `Messages` tab when a user clicks on the `Message` button in their profile panel.

We'll do this using [ngx-bootstrap](https://valor-software.com/ngx-bootstrap/#/tabs).

In `member-detail.component.ts`, add a `ViewChild()` property and a `selectTab()` method:

```typescript
@ViewChild('memberTabs') memberTabs: TabsetComponent;

//  ...

selectTab(tabId: number) {
    this.memberTabs.tabs[tabId].active = true;
}
```

In the `member-detail.component.html`, add a click listener to the `Message` button:

```markup
<button type="button" class="btn btn-secondary" (click)="selectTab(3)">Message</button>
```

`ngx-bootstrap` passes the tab we want as a query string and handles it for us. We're passing `3` as the parameter because it's the 4th tab (0-indexed).

Now, we'll try to do the same thing from our `Messages` component. This time we'll have to pass the query parameters ourselves.

In `messages.component.html` - in the second `<tr>` element where we have our `routerLink` set up - we can also add query parameters.

```markup
<tr 
    *ngFor="let message of messages"
    [routerLink]="['/members', messageContainer == 'Outbox' ? message.recipientId : message.senderId]" 
    [queryParams]="{tab: '3'}">             <!--Added-->
```

We can then subscribe to the query parameters in the `ngOnInit()` method in the `member-detail.component.ts` similarly to how we're getting the user query params:

```typescript
ngOnInit() {
    this._route.data.subscribe(data => {
      this.user = data['user'];
    });

    this._route.queryParams.subscribe(params => {
      this.memberTabs.tabs[params['tab']].active = true;
    });

    //  ...
```

We can also add this to the button with the envelope icon in our main list of users in the `MemberCardComponent`. Open up `member-card.component.html` and add the `routerLink` and `queryParams`:
