Translate to TypeScript

I'm trying to send messages in WebSocket with TypeScript. By staying this in my console, it works:

socket.on('displayHello', function(data) {
    $.pnotify({
        title: "Hello",
        text:  data.from + " te dis bonjour " + data.to,
        type:  "info"
    });
});

I want to translate it into TypeScript : 

public onMessage(): Observable<any> {
  return new Observable(observer => {
    this.socket.on('displayHello', (data) => {

      observer.next(data);
    });
  });
}

I do not see how to do with the pnotify parameter because it is not recognized by TypeScript.

When I try this : 

public onMessage(): Observable<any> {
return new Observable(observer => {
  this.socket.on('displayHello', (data) => {
    observer.next(data);
    $.pnotify({
      title: 'Hello',
      text:  data.from + ' te dis bonjour ' + data.to,
      type:  'info'
    });
  });
});
}

I have this error : 

TS2339:Property 'pnotify' does not exist on type '(search: string) => ElementFinder'

The problem you face could be solved by installing the type definition for pnotify.

Depending if you're using npm or yarn you need to perform npm install --save-dev @types/jquery.pnotify or yarn add --dev @types/jquery.pnotify.

Also make sure that you're using a recent version of TypeScript that does automatically locate type definitions within the @types/-Folder
