This 5-minute video shows how to convert a SOAP service into a REST API using API Express. Once you have a REST API, you can easily build a mobile app with that API.

Learn how to use the Appery.io Backend Services from our short videos on our YouTube channel.

One of the new key features of API Express is that you can build apps offline with the synchronisation functionality so when you go online all off your changes have been synchronised. The ClientSDK library has a set of methods, which when you execute can you build more powerful apps offline. The last Appery update bought us the ClientSDK library of API Express’ new methods to work with action histories made offline:

• revertLocalChanges – reverts all local changes made in offline mode without clearing the cached data.
  
• getDeferredActions – returns the iterator, which you can use further to iterate through the history array items.
• saveDeferredActions – saves changes to a history, if there was any changes.

ClientSDK will automatically detect the network state and when a device is connected to the internet the ClientSDK synchronises with the server, and sends all offline changes (actions history) made by the user. You can find more information here.

Internationalisation is one of the must have feature when building global reach mobile apps. An Angular Translate module can be really helpful in translating your app UI. It can be included into an Appery.io app in a few quick steps:

• Go to the Angular Translate page and download the latest release bundle. Inside this bundle you’ll find angular-translate.min.js file – the one that you need to upload.
• Open your AngularJS Appery.io app, click CREATE NEW > JavaScript. Type angular-translate.min for the name and select Upload from file, and browse for this file on your PC. Also, change its Type to Angular module, check the Use shim check box and finally, type pascalprecht.translate for Shim exports: input. Click Create JavaScript once the file will be uploaded.
• Now, another module should be created. It will be responsible for the Angular Translate configuration. Perform CREATE NEW > JavaScript, type AngularTranslate for the name, and choose Angular module for Type. Click Create JavaScript.
• You’ll see an Angular module template and a lot of commented configuring options. First, this module requires pascalprecht.translate as dependency, so add it  to square brackets. Here is how it should look:

  var module = angular.module('AngularTranslate', ['pascalprecht.translate']);

• Configuration logic should be added to the module.config function. Here is how your whole module should look when the configuration logic has been added:

  define(['require', 'angular'], function(require, angular) {
      
      var module = angular.module('AngularTranslate', ['pascalprecht.translate']);
      
      module.config(
          
          ["$translateProvider", function($translateProvider) {
              $translateProvider.translations('en', {
                  TITLE: 'Hello',
                  FOO: 'This is a paragraph.',
                  BUTTON_LANG_EN: 'english',
                  BUTTON_LANG_DE: 'german'
              });
              $translateProvider.translations('de', {
                  TITLE: 'Hallo',
                  FOO: 'Dies ist ein Paragraph.',
                  BUTTON_LANG_EN: 'englisch',
                  BUTTON_LANG_DE: 'deutsch'
              });
              $translateProvider.preferredLanguage('en');
          });
      
  }]);

• The last step is to create a simple UI and check the translation engine. Go to any page in your app, place a Button on the page and provide {{ 'TITLE' | translate }} for its Text property. Launch the app!
• If you see Hello on the button – you’re done.

One option is to customise the translation mechanism to initiate the language based on the browser or device language. For example, you can get the browser or device language like this:

$translateProvider.determinePreferredLanguage();

Try Ionic app backup with Angular Translate included if you facing some issues.

Component context menu

When building a mobile app in the Appery.io visual App Builder it’s very common to place the same component in multiple places. Before, you had to drag each component separately, now there is a simpler and faster to do this with our new copy and paste capabilities.

AngularJS projects in Appery.io use the standard copy and paste functionality that you are familiar with, plus you can clone (duplicate) a component. This means that you can copy your component via a context menu or hotkey (CTRL+C), and paste it even into a different AngularJS project! In order to open the context menu, select any component and click the cog icon.

You can find more information about UI components in Appery.io in our documentation, and make sure you check out all of our mobile development tips.

This is our second major platform update in 2016, we are excited to share our new features and benefits to help you build enterprise apps fast.

New enterprise components in API Express

There are two new features of our API Express, these new service components are for creating advanced service logic using the visual builder. Our new features to API express are:  Script and ServerCode. Both components allow you to write custom service logic using JavaScript.

API Express visual editor enterprise components

• ServerCode component – allows call Server Code scripts from the API Express. This will be beneficial if your app relies on some server-side logic that is written as a Server Code script. Read more about this component here.
• Script component – can be used for changing the body structure before passing the data to another component. Find more on Script component in documentation.

“Going mobile” is more than just having a website—it means a whole load of things. It’s about reaching and engaging with your members in a new way, and offering your members a different way to receive information; making information accessible at any time and in any place.

While a website may provide information for your members, you also want to have a way to get your members talking to each other and joining in events and activities. We are in a society where we are constantly looking for up-to-date information, mobile apps provide us with this and our phones are within reach at all times. There are numerous angles your non-profit can take when it comes to creating a mobile app, some opt for informational such as The Red Cross, which provides weather alerts to help citizens better prepare for potential natural disasters. But, for your non-profit organisation, being mobile can mean any of the following things:

• Mobile Web—optimising your website, content, and donation forms for mobile devices.
• Mobile messaging— increasing your communication with your members, co-workers, and donors via text messages.
• Online donations/text-to-give—providing a way for your members to donate through their mobile devices via a mobile optimised online donation form or website, or by texting a donation directly to your organisation.
• Mobile Apps—creating your own customised application for your members to download to their smartphones or tablets for easy access.

Popular Bootstrap Grid is available in Appery.io’s Bootstrap project as an UI component that can be dragged and dropped to the page. The following steps show how to change grid cell sizes for different screen resolutions:

1. First open the AngularJS / Bootstrap project and place the Grid component to the page.
2. Now, if you will look at top right corner of the grid you’ll see a green plus button, this button will add a new row to your grid. If you don’t need to add a new row, but want to add new cells to existing row click on one of the grid cells and then choose GridRow through the breadcrumbs:
   
3. A green “+” sign now will add a new cell to an existing row.
4. You can configure the size for each cell for the four screen sizes. Click on the grid cell and the expand Columns properties in the PROPERTIES to the right of the screen. Type a number from 1 to 12 to define how it will look on the screen:
   

Don’t forget that you can emulate page size directly inside the editor, and when testing the app in browser by clicking XS, SM, MD and LG buttons.

It doesn’t seem that long ago when the first 4G smartphone hit the market, yet the wireless industry is already preparing for 5G. As each of the four worldwide mobile phone carriers are getting ready to bring us 5G, smart phone chipmakers, and major network equipment companies are joining the race to provide their customers with the “ultra-fast” 5G network.

However there are numerous hurdles which the industry will have to jump over before we will be seeing the 5G symbol on our smartphones any time soon. The reasoning for this? It has yet to be decided what 5G even means, let alone what it will look like when it finally arrives. What we do know is that 5G will soon become a necessity.
