What we'll cover

  • A little background on headless & decoupled Drupal
  • A case study on a decoupled drupal implementation powering a kiosk
  • A quick demo showing how easy it can be to get started

Fully Decoupled

Why you might Choose a Decoupled architechture?

  • Flexibility in your presentation layer
  • Increased speed/responsiveness
  • More interactive interfaces
  • Front-end devs don't need to know Drupal

Some Possible Downsides

  • Introduces more complexity
  • Lose a lot of out-of-the-box drupal
  • Can be more difficult for small or single-person teams

A Case Study

REST UI (contrib)

Serialization

HTTP Basic Authentication

RESTful Web Services are available in d8 core

angular.module('calendar.services', [])
.provider('CalendarConfiguration', function CalendarConfigurationProvider (){
  this.addGoogleCalendar = function(calendarLabel, calendarId, apiKey){
    // ...Store config details for a google calendar.
  };
  this.addIcalCalendar = function(calendarLabel, calendarId, apiKey){
    // ...Store config details for an Ical
  };
});

Creating an angular service for calendar config

separate methods for google & ical

angular.module( 'kiosk', [
  'calendar.services'
])
.config( function kioskConfig( CalendarConfigurationProvider ){
  CalendarConfigurationProvider.addIcalCalendar('Sessions', 'http://badcampdemo.local/sessions');
  CalendarConfigurationProvider.addGoogleCalendar('Bay Area Events', 'foo@group.calendar.google.com');
})

Allows one-line configuration for each calendar source

note both ical and google calendars used above

calendar from legacy cms

angular.module('calendar.services', [])
.provider('CalendarConfiguration', function CalendarConfigurationProvider (){
  // ...
})
.service( 'calendarService', ['$http', '$q', 'CalendarConfiguration'],
  function($http, $q, CalendarConfiguration) {
    
    var fetchGcalEvents = function() {
      // Fetch calendar data using $http and parse relevant details
      // Return a promise.
    }

    var fetchIcalEvents = function() {
      // Fetch calendar data using $http and parse relevant details
      // Return a promise.
    };

  });

In our angular calendar services module, we define methods to fetch each type of feed



    // ...

    var fetchEvents = function(){
      CalendarConfiguration.getGoogleCalendars().forEach(function(){
        calendarEvents.push(fetchGcalEvents());
      });
      CalendarConfiguration.getIcalCalendars().forEach(function(){
        calendarEvents.push(fetchIcalEvents());
      });

      $q.all(calendarEvents).then(function(promiseResolves){
        // Combine our resolves.
        var data = [];
        promiseResolves.forEach(function(promiseResolve){
          data.concat(promiseResolve);
        });

        // resolve the original promise.
        promiseObj.resolve(data);
      });
    };

And then we write a wrapper to resolve all the data at the same time

angular.module( 'kiosk', [
  'calendar.services'
])

.config( function kioskConfig( CalendarConfigurationProvider ){
  CalendarConfigurationProvider.addIcalCalendar('Sessions', 'http://badcampdemo.local/sessions');
  CalendarConfigurationProvider.addIcalCalendar('Bay Area Events', 'foo@group.calendar.google.com');
})

.controller( 'KioskCtrl', function KioskCtrl($scope, calendarService) {
  calendarService.fetchEvents().then(function(events){
    $scope.events = events;
  })
});

Allows us to populate $scope with a an array of all our events
