Portals Extension Module

The Portals Extension Module has been created to allow 3rd party content and applications to be integrated inside Portals. The accompanying Portals API is divided into multiple parts: a message bus, query functions, trigger functions and a MySight interface.

Setup

The Extension module allows integration of your application into portals by providing an iFrame for your content and an API for communciation with Portals. The module accepts an url and allows dynamic GET parameters to be passed to your application through that url. Just select the participant variables and master data you want to pass to your application and provide names for the GET keys.
A portals page can have several Extension modules on a single page and all modules can communicate with each other through the provided message bus in the Portals API.
For enhanced data exchange with EFS, we recommend that your application uses the EFS ServiceLayer in the backend to query and update data in EFS.

Import

In your application, you have to import the PortalsAPI JavaScript file in order to be able to use the message bus or other Portals API functions.

<script src="https://{yourEFSInstallation}/public/modules/portals/dist/portalsApi/portalsApi-1.0.js"></script>

Initialization

After your document has finished loading you need to initialize the api. This registers your document with Portals for messaging.

<script>
    Questback.portalsApi.initialize()
        .then(function() {
            ...
        }
        .catch(function(error) {
            ...
        });
</script>

Checking initialization status

You can check the initialization status by calling isInitialized, though it is generally recommended to do your api operations in the then-handler of the initialize method as shown above.

Questback.portalsApi.isInitialized();

Unregister

You can completely revert the registration of the iFrame and unregister all its handlers by calling unregister.

Questback.portalsApi.unregister();

Message bus

The message bus is intended for communication between extension module iFrames. You can send and listen to your own events and transfer any data you want.

Listening for messages

After the initialisation has been completed you can start to register handlers for events from other iFrames. The example code registers a handler for an event called "myEvent". This is an event name that you expect other iFrames to send messages for.

Questback.portalsApi.initialize().then(function() {
    Questback.portalsApi.bus.subscribe('myEvent', function(data) {
        ...
    });
};

Sending messages

Sending a message to other iFrames is just as simple. You just call the send method with an eventname that you chose and a data object as second parameter.

Questback.portalsApi.bus.send('myEvent', { foo : "bar"});

Just note that you do not get a result back from this call, as it works like a broadcast. Also note that by default the sending iFrame will not receive its own event back, even if it has registered a handler for it. You can supply a third parameter to send with a value of true to force sending the event to the sender iFrame, too.

Stop listening for messages

You can remove handlers for events by an eventname.

Questback.portalsApi.bus.unsubscribe('myEvent');

Note that this removes all handlers for the given eventname for this iFrame at once.

Query data from Portals

The api supplies a set of methods to request specific data from Portals.

query.portalInfo

Get information about the portal.

Questback.portalsApi.query.portalInfo().then(function(result) {
    console.log(result.portal.id);
});

query.user

Get the user object of the currently logged in user. Returns null if there is no logged in user.

Questback.portalsApi.query.user().then(function(result) {
    console.log(result.user);
});

query.language

Get the language object of the currently used language.

Questback.portalsApi.query.language().then(function(result) {
    console.log(result.language);
});

query.deviceInfo

Get information about the client device.

Questback.portalsApi.query.deviceInfo().then(function(result) {
    console.log(result.device.isMobile);
});

query.ajax

Makes an ajax call to the portals server and returns the result.

Questback.portalsApi.query
    .ajax('GET', '/api/portal/client/pages')
    .then(function(result) {
        console.log(result);
    })
    .catch(function(error) {
        console.log(error);
    });

Trigger actions in Portals

The api supplies a set of methods to trigger specific actions in Portals.

trigger.height

Set the iFrames height to a specified value, given as a string including the unit.

Questback.portalsApi.trigger.height('300px');

trigger.autoHeight

Set the iFrames height to the height of its content. This is done once per call, not repeatedly. So you have to react to resize events yourself.

Questback.portalsApi.trigger.autoHeight();

trigger.logout

Log out the current user from Portals and thus redirect to the configured landing page. The iFrame will be removed from the DOM by this opreation.

Questback.portalsApi.trigger.logout();

trigger.route

Redirect to the given page slug. The iFrame will be removed from the DOM by this opreation.

Questback.portalsApi.trigger.route('targetPageSlug');

MySight interface

There are a number of methods to interact with Tableau in a MySight module. For all of these you need the pageModuleIdentifier of a MySight module to target your requests. This identifier is set in the Portals CMS in the settings for the MySight page module and can be reused on other pages for the same or even different Tableau instances.

Listening to MySight Tableau events

The api supports registering for a number of Tableau events. The supported events are:

FIRST_INTERACTIVE
VIZ_RESIZE
TAB_SWITCH
FILTER_CHANGE
PARAMETER_VALUE_CHANGE
MARKS_SELECTION

To register a listener for an event use the apis bus methods together with the apis tableau event constants:

Questback.portalsApi.bus.subscribe(
  Questback.portalsApi.mySight.tableauEventFirstInteractive, function(event) {
    console.log(event);
});

Questback.portalsApi.bus.subscribe(
  Questback.portalsApi.mySight.tableauEventVizResize, function(event) {
    console.log(event);
});

Questback.portalsApi.bus.subscribe(
  Questback.portalsApi.mySight.tableauEventFilterChange, function(event) {
    console.log(event);
});

Questback.portalsApi.bus.subscribe(
  Questback.portalsApi.mySight.tableauEventTabSwitch, function(event) {
    console.log(event);
});

Questback.portalsApi.bus.subscribe(
  Questback.portalsApi.mySight.tableauEventParameterValueChange, function(event) {
    console.log(event);
});

Questback.portalsApi.bus.subscribe(
  Questback.portalsApi.mySight.tableauEventMarksSelection, function(event) {
    console.log(event);
});

Note that you will receive events coming from any MySight Tableau instance on the page, so upon receiving an event you might have to make sure that you are only handling events coming from a specific instance by checking the pageModuleIdentifier in the event object.

Questback.portalsApi.bus.subscribe(
  Questback.portalsApi.mySight.tableauEventVizResize, function(event) {
    if (event.mysight.pageModuleIdentifier === 'page-module-identifier-to-handle') {
        // Do something
    }
});
