Ionic 4 Is Coming!

Posted: May 23rd, 2019Author:

We would like to provide you with information about our May release. We have only one new feature, but what a feature—Ionic 4!


The latest, most powerful version of the popular framework will be available for Appery.io next week. It’s packed with exciting new features that made waiting worthwhile! Appery.io Ionic 4 framework supports the latest Angular version 7 and Cordova 8. It will be released as a beta, because we plan to continue working on it and add new features and components.

Please note that Ionic 3 support will be canceled once the Ionic 4 beta period is finished, but before then you’ll have plenty of opportunity to update your Ionic 3 projects to version 4.

 

New Tutorial on Using IndexedDB to Work with Images Offline

Posted: April 19th, 2019Author:

A piece of good news for the users who were interested in combining Login-Registration App and IndexedDB Storage but lacked information on how that can be done practically!

The Appery.io team would like to bring to your attention that a new tutorial has been published that provides step-by-step instructions on building an app that will get user images from the custom Files collection and make them available when the device is in offline mode.

The tutorial describes in details how one can save a set of images from Appery.io Files collection into IndexedDB cache with further making them available to users when the app goes offline.

Besides, it presents the list of functions provided by the IndexedDB Storage plugin which was introduced in Appery.io builder for your convenience:

A very interesting detail: this sample app can be published either as a regular iOS and/or Android app or as a PWA website.

Enjoy your programming with Appery.io!

What’s in the March 2019 Platform Update (Psssst… PWAs)

Posted: March 6th, 2019Author:

Our March platform update rolls out on March 10. It will be focused on support for progressive web apps (PWAs).

PWAs are a new software development technology. Like other hybrid solutions (Cordova, Electron, etc), PWAs work seamlessly on desktop, mobile, and tablets using a single source codebase.

“Progressive web applications (PWAs) are web applications that load like regular web pages or websites but can offer the user functionality such as working offline, push notifications, and device hardware access traditionally available only to native applications. PWAs combine the flexibility of the web with the experience of a native application.” © Wikipedia

If you are still using a classic hybrid application, you have to  make a build for every platform you want to support and then distribute your application to an app market like Google Play or App Store. That means you need to register a developer account, buy platform-specific hardware and software, build and test your application for every platform, and then publish your application to the market. Once done, your application can be removed from the application market by a vendor if it doesn’t pass their review processes.

A PWA has the advantage that you are the only person who manages your application. All you need to publish your application is to be the host. If you are an Appery.io customer, you can do this in just a few clicks. Below, we describe how to do this.

Here is a checklist from the Google Developers site that walks you through how to convert existing apps to PWAs. With Appery.io, it’s not necessary to do this, but this is a helpful resource just in case.

We have added a PWA option for all project types supported by Appery.io. You don’t need to change any code in your existing app to make it a PWA.

Just open your app in the AppBuilder and configure the PWA settings like application name, icon, background color, etc.

The next step would be publishing your app.

PWA App Publishing.

Now, anyone who opens your app published in a web browser on a mobile device will be able to add it to the launch screen without installing it from the application market.

How to Build a Sample Ionic 3 Search App

Posted: February 28th, 2019Author: , and

This is a continuation of the post How to Build a Sample Ionic 3 List App. In this document, we will provide step-by-step instructions on modifying your Ionic 3 list app so that data can be shared between its pages.

Remember, you can only proceed with the steps in this post only after you have made sure the application from the previous post works as expected.

  1. To begin with, go to the Databases tab and open the database to be used in the app. Make sure the needed collection has a column of string type named description. If needed, create it by clicking the +Col button and filling it with data:
  2. Once done, switch to the Apps tab and open the Sample Ionic 3 app created in the previous blog post. In the Project view tree, click Model. There, define the models so that they look like the following (note that, here, the SingleItem model is renamed to Item):
  3. A Query service from the collection should be imported in this step: Create new > Database Service; in the new window, select the database and check the Query service checkbox of the needed collection. Click Import selected services to confirm: The subfolder with the corresponding name should now have been added to the Services folder in the Project view tree.
  4. It is time to add a new pageCreate new > Page, set the page name to Details, and confirm by clicking Create Page.
  5. Under the PROPERTIES tab, change the Navbar Text component to Details.
  6. Drag and drop a Text component on the page and define its Text property as {{name}} selecting h1 for the Container property.
  7. Now, add another Text component to the page and set its Text property to {{description}}:
  8. Switch to the CODE tab, click Edit internal includes, and, in the pop-up window, scroll down to find { NavParams } from “ionic-angular”. Then check it and confirm the selection by clicking Save:
  9. Then, proceed to the Variables section adding and defining variables as follows (ensure the private navParams variable is checked in the Add DI checkbox):
  10. To finish with the Details page, add a new function to it, name it constructor, and define it with this JavaScript code:
  11. In the next step, some changes to the existing List page should be made. So, in the DESIGN view, under the PROPERTIES tab, select the Navbar Text component and rename it to List.
  12. Now, place the Input component on the page and define its [(ngModel)] property as query.
  13. Modify the existing List item by adding a new attribute (click)navCtrl.push(“Details”, item):
  14. Rename the Button Text property to SEARCH and change its (click) attribute to search() that will initiate navigation to the other page (Details) of the app (if you decide to keep the list functionality in the new app, create a new button for search so that there will be two of them):
  15. Once done, open the CODE tab and click Edit internal includes. Check 2 dependencies: { NavController } from “ionic-angular” and your added query dependency (the last on the dependencies list) in the Dependencies pop-up window. The List service can be unchecked now if not used for the modified app.
  16. Save. The services with the corresponding names should now be added under Internal includes:
  17. After that, add 2 variables: query of type String and queryService of the type of your query service (added to Internal includes). Make sure the Add DI checkboxes for private navCtrl and queryService variables are checked. (Delete the listService variable if it will not be used in the app.)
  18. Finally, add a function to the page named search and define it with this JavaScript code (the loadList function will not be used so it can be deleted):

    Voilà!

    The app is ready for testing. Click the arrow button next to the Test menu item. In the drop-down, select Show without frame and click Launch. The List page will be loaded. Enter the name of the item from your database collection (for example, Coat) and click SEARCH. The item Coat will be returned on the page. Then, click this item to open the Details page with the item description:

    Note: You might also want to leave the List service functionality created earlier. In this case, both List and Query services should work as expected.

Update from Google Play

Posted: February 20th, 2019Author: and

We would like to inform you that Google has updated their Developer Policy to make apps published with Google Play compliant with user Privacy, Security, and Deception policy and now restricts the use of high risk or sensitive permissions, including the SMS or Call Log permission groups.

Please review these permissions in your Appery.io project(s) on the App Settings page (Project->App Settings->Android Permissions).

If such permissions are not used by your application but are enabled, please disable them. Once done, upload an updated app version to Google Play to ensure it will be allowed by Google.

If your application requests the use of such permissions, you will be required to submit the Permissions Declaration Form to receive approval from Google Play. Once your Permission Declaration is reviewed and your app is approved for policy compliance to the Google Play Developer Distribution Agreement, your application will be published.

Note:

Completing the form is required even if the application does not use such permissions, so please select any items there and add a comment like: “I’ve selected one just to submit a form, the app doesn’t require that feature”.

How to Build a Sample Ionic 3 List App

Posted: February 9th, 2019Author: , and

This post will describe step-by-step how to build a sample app with Ionic 3 that will retrieve a list from your database collection.

  1. Create a new Ionic 3 app. From the Apps page, click Create new app > Ionic 3 (beta), give it a name, and click Create.
  2. Import the List service from any existing or newly created Appery.io database collection. Create new > Database Service, select the needed database and check the List service checkbox confirming import.
    The subfolder with the corresponding name should now have been added to the Services folder in the Project view tree.
  3. Add a model called SingleItem of type Object and 2 attributes: name and _id. Then, add the Items model of Array type and define it in the following way:
  4. Open Pages and rename Screen1 to List using the “cog” sign.
  5. Under the DESIGN tab, add a List component to the List page and delete the 2nd and 3rd items on the list.
  6. Select the List item and add the property *ngFor=let item of items. Also, set the Text property to {{item.name}}.
  7. Now, add a Button component to the page, select it, and define its Text property as Load List and (click) property as loadList().
  8. Switch to the CODE tab, click Edit internal includes, check your added list service, and save:The service with the corresponding name should now be added under Internal includes.
  9. Add 2 variables: items of type Items and listService of the type of your list service (added to Internal includes). Check the Add DI checkbox for listService.
  10. Finally, add a function, name it loadList, and define it with this JavaScript code:

Voilà!

You can now test your app. To do so, click the arrow button next to the Test menu item. In the drop-down, select Show without frame and click Launch. The page will be loaded. Now, click the Load list button. The list appears loaded with the items from the database:Note: To learn how this app can be modified to search and share data across its pages, proceed with this post.

Go Digital on a Shoestring Budget with Appery.io PWAs

Posted: September 17th, 2018Author:

A Progressive Web App (PWA) is the most cost-effective way to go on the market fast with a mobile app. It can help dramatically save on development and maintenance if you compare a PWA with a native app. PWAs take advantage of the open standards offered by web browsers to provide the benefits of a rich mobile experience.

Sample PWA

This sample Appery.io PWA developed in 16 hours looks like a native app and can work offline.

Native-like mobile experience

Surf over in iOS Safari or Android Chrome to https://pizza-pwa.app.appery.io/ and add the opened page to your phone’s home screen to create a seamless native-like mobile experience.

Please note that changing the demo database content is disabled.

Working offline

A service worker (a script staying behind the scene) uses a cache mechanism to manage HTTP requests. Opening the app for the first time online saves all the data on to the device automatically. When offline, searching and listing stay fully functional effortlessly. (Please note that iOS 11.4.1 provides limited support of this feature.)

Programming a PWA

Making a PWA is as easy as 1, 2, 3 with Appery.io‘s support for the development of Ionic 3, Ionic 1, and JQuery apps. Just pick the Ionic 3 option to start developing a PWA. To review or reuse the sample Pizza PWA download this zip archive. The demo app consists of:

  • HTML5 pages
  • A service worker
  • An Appery.io Mongo database
  • A JSON-based manifest

After restoring it into Appery.io, make sure that the app refers to a valid database, and the appropriate plug-in is installed. Once all these steps are taken care of, run the building process. Voilà, the demo app is ready for testing.

Testing a PWA

Google published a checklist that breaks down all the things that are important in order to develop a basic PWA. And, the checklist shows you how to go further to make a truly advanced PWA, one that provides a more meaningful offline experience and reaches interactivity even faster, along with other improvements.

For verification of many items on this checklist, Google suggests using the Lighthouse tool.

In addition, the following tools can be utilized to validate some items on the checklist:

  • Selenium and other WebDriver-based frameworks
  • Headless browser tools like Google puppeteer, PhantomJS, and JSDom
  • Appium and Espresso
