Building your first mashup with Qlik Sense SaaS
This topic assumes that you are using an external web server to host your mashup. To keep things simple, we have omitted any code related to authentication. If you want to add an authentication flow to your script, see Authentication using browser redirection with Qlik Sense SaaS. Let's get started by building a mashup using the helpdesk app that is provided with Qlik Sense Desktop.
Creating the container
Create a folder named helpdesk to contain your assets.
Creating the main script file
Create the main JavaScript file helpdesk.js. This file is placed in the helpdesk folder.
Configuring your Qlik Sense host
The Qlik Sense host being used must be configured in your mashup. This is needed for the following reasons:
- To define the actual Qlik associative engine connection, which is used when you open an app or get a list of apps. This is covered by the config JavaScript object, used as a parameter in the openApp call.
- To define where the Qlik Sense client side software and files should be loaded from. This is achieved by configuring RequireJS with the require.config call and setting the baseUrl.
- To define the web integration ID, which is necessary to enable cross-domain resource sharing. For details on how to find the web integration ID, refer to Managing web integrations.
var config = {
host: 'QSE_domain', //for example, 'abc.us.example.com'
prefix: '/',
port: 443,
isSecure: true,
webIntegrationId: 'web-integration-id-here'
};
require.config( {
baseUrl: ( config.isSecure ? "https://" : "http://" ) + config.host + (config.port ? ":" + config.port : "") + config.prefix + "resources",
webIntegrationId: config.webIntegrationId
} );
Setting the global require and alert
The JavaScript file is loaded in the browser when your mashup is used. RequireJS is used as a module loader.
require( ["js/qlik"], function ( qlik ) {
qlik.on( "error", function ( error ) {
$( '#popupText' ).append( error.message + "<br>" );
$( '#popup' ).fadeIn( 1000 );
} );
$( "#closePopup" ).click( function () {
$( '#popup' ).hide();
} );
//open apps -- inserted here --
//get objects -- inserted here --
} );
Connecting to the Qlik Sense app
You need to connect to the Qlik Sense app containing the objects you want to display on your web page.
//open apps -- inserted here --
var app = qlik.openApp( 'AppId', config ); //Replace 'AppId' with the actual helpdesk app ID
Retrieving the Qlik Sense objects to use
You then need to fetch the objects you want to display.
//get objects -- inserted here --
app.visualization.get('uETyGUP').then(function(vis){
vis.show("QV01");
} );
app.visualization.get('xfvKMP').then(function(vis){
vis.show("QV02");
} );
app.visualization.get('rJFbvG').then(function(vis){
vis.show("QV03");
} );
app.visualization.get('PAppmU').then(function(vis){
vis.show("QV04");
} );
app.visualization.get('ca4463f1-31fc-4eed-98a7-5e770b8387f3').then(function(vis){
vis.show("QV05");
} );
app.visualization.get('ff551649-420e-428d-bede-38accf80dce8').then(function(vis){
vis.show("QV06");
} );
Pre-selecting fields in the app
Making pre-selections in the app before rendering visualizations is a best practice. It allows the engine to do calculations once, which is quicker and puts less burden on the engine than making selections after the visualizations are rendered.
//function to pre-select fields
function getCaseOwner(callback) {
// call some backend functionality and call the “callback” function when ready
callback("Thomas R. Allman");
}
//call getCaseOwner with callback function
getCaseOwner(function(caseOwner) {
app.field("Case Owner").selectMatch(caseOwner)
.then(function() {
//get objects -- inserted here --
app.visualization.get('uETyGUP').then(function(vis){
vis.show("QV01");
} );
app.visualization.get('xfvKMP').then(function(vis){
vis.show("QV02");
} );
app.visualization.get('rJFbvG').then(function(vis){
vis.show("QV03");
} );
app.visualization.get('PAppmU').then(function(vis){
vis.show("QV04");
} );
app.visualization.get('ca4463f1-31fc-4eed-98a7-5e770b8387f3').then(function(vis){
vis.show("QV05");
} );
app.visualization.get('ff551649-420e-428d-bede-38accf80dce8').then(function(vis){
vis.show("QV06");
} );
})
})
Creating the main HTML file
Create an HTML file, name it index.html, and save it in the helpdesk folder.
Defining the relationships
The relationship between the current document and the linked Qlik Sense defined style sheet is specified in a link rel tag inside the head of the HTML file.
<link rel="stylesheet" href="https://QSE_domain/resources/autogenerated/qlik-styles.css">
<script src="https://QSE_domain/resources/assets/external/requirejs/require.js"></script>
<script src="helpdesk.js"></script>
Adding an internal style sheet
Add some internal styling inside the head of the HTML file to organize the presentation of the charts.
<style>
div.flex-container {
display: flex;
flex-wrap: wrap;
margin: 0 45px 45px 0;
}
div.qvobject {
flex: 1 1 auto;
height: 300px;
min-width: 400px;
margin: 45px 0 0 45px;
}
</style>
Placing the Qlik Sense objects
The Qlik Sense objects that have been defined in the JavaScript file are placed inside div tags inside the body of the HTML file.
<div class="flex-container">
<div id="QV01" class="qvobject"></div>
<div id="QV02" class="qvobject"></div>
<div id="QV03" class="qvobject"></div>
<div id="QV04" class="qvobject"></div>
<div id="QV05" class="qvobject"></div>
<div id="QV06" class="qvobject"></div>
</div>
Testing the mashup
Now is a good time to test your mashup.
- Log into Qlik Sense SaaS.
- Access the mashup:
Example: Path to Helpdesk example
https://your_web_server_URL:port
