qdt-components (Qlik Demo Team Components) is a library of components that we have developed in the demo team and that have been used in most of our mashups found in webapps.qlik.com and demos.qlik.com. It's a collection of filters, tables, barcharts, selection toolbars, or even simple getting/creating object methods from the Visualization Api. You do not have to worry about connection strings, loading Requirejs, jQuery etc. Everything is taken care for you! The library can be used in a simple html page by loading the qdt-components.js or in React and Angular2+ via npm.

Today, I will show you how to load a simple object and create a session barchart, in simple html and Angular 5

Simple HTML

In your HTML, add the following:

<head>
  <script type="text/javascript" src="qdt-components.js"></script>
</head>
<body>
  <div id="qdt1"></div>
</body>

In your Javascript code, add:

var qConfig = {
   "config": {
      "host": "your-sense-server.com",
      "secure": true,
      "port": 443,
      "prefix": "/",
      "appId": "133dab5d-8f56-4d40-b3e0-a6b401391bde"
   },
   "connections": {
      "vizApi": true,
      "engineApi": false
   }
}

var QdtComponent = new window.qdtComponents.default(qConfig.config, qConfig.connections);

var element = document.getElementById('qdt1');

QdtComponent.render('QdtViz', {id: 'a5e0f12c-38f5-4da9-8f3f-0e4566b28398', height:'300px'}, element);

And you are done.

Live Demo: Simple html with qdt-components

Angular 5

Install Angular CLI (https://cli.angular.io/) or get the prepared template
Install the package:

npm install --save qdt-components

Create new component by typing in the command line

ng generate component components/qdt-components --style=less

In your qdt-component.component.ts import the library and import or set the qConfig with the connection details

import { Component, OnInit, ElementRef, Input } from '@angular/core';
// import * as qConfig from '../../../qConfig.json';

import QdtComponents from 'qdt-components';

let qConfig = {
   "config": {
      "host": "sense-demo.qlik.com",
      "secure": true,
      "port": 443,
      "prefix": "/",
      "appId": "133dab5d-8f56-4d40-b3e0-a6b401391bde"
   },
   "connections": {
      "vizApi": true,
      "engineApi": false
   }
}

Replace the class with:

export class QdtComponentComponent implements OnInit {
   @Input() Component: Function;
   @Input() props: object;

   static QdtComponent = new QdtComponents(qConfig.config, qConfig.connections);

   constructor(private elementRef: ElementRef) { }

   ngOnInit() {
      QdtComponentComponent.QdtComponent.render(this.Component, this.props, this.elementRef.nativeElement);
   }
}

After this, you can start using it in any other component. In the HTML, add:

<qdt-component [Component]="'QdtViz'" [props]="{id: 'a5e0f12c-38f5-4da9-8f3f-0e4566b28398', height:'300px'}"></qdt-component>

Hi @FG ,

I dont have any experience using react in a extension. I think you would need to package the file in a very specific way, and I dont know how to do that. I only know how to do standard structured extension using vanilla js or AngularJS.

Are you using the library in an extension or in a mashup from dev-hub?

you get a 404 error so maybe if you try and run

npm i -s qdt-lui

Hi Yianni,

Good to see you in the Integration meetup the other day. Thanks for everything you are doing relating to QDT components.

I was wondering if QDT components can be used in conjunction with a connection to the Engine api so that the Engine data and the QDT components share the same session?

Thanks,
Andy

Hello Andy and my apologies for not making it clear enough.

YES!

Most of the components are with the Enigma.js, Picasso.js and the Engine API and they share identity. Only the first two examples from the link below are from the Capability API.

Here is a list of what i have shown, fell free to ping me in slack or email for more details

Hi @Yianni_Ververis ,

Thank you so much for making this re-usable libs, which really save our time.

I am building Qlik Sense Mashup, i have copied the 'qdt-react-website-master' to my local and updated the below configuration, which works fine in localhost:8080 and qlik sense desktop. but it is not working when it is deployed to dev-hub cloud.

I am getting below errors:

My configuration looks below:

import QdtComponents from 'qdt-components';

const useUniqueSessionID = Math.random().toString(32).substr(2, 8);
const deployOptions = 'qlik';

const options = {
  config: {
    host: deployOptions === 'react' ? 'localhost' : window.location.hostname,
    secure: deployOptions === 'react' ? false : window.location.protocol === 'https:',
    port: deployOptions === 'react' ? 4848 : window.location.port,
    prefix: '',
    appId: '54ba6993-1558-42ab-9981-7ae205a30242', // Helpdesk
  },
  connections: {
    vizApi: true,
    engineApi: true,
    useUniqueSessionID,
  },
};
