Build Responsive Web and Mobile Apps with Bootstrap, AngularJS and Appery.io

This webinar shows how to build responsive web and hybrid mobile apps using Bootstrap and AngularJS using Appery.io.

Instantly Build REST APIs with Server Code

The Appery.io Server Code allows to build any app logic and instantly expose it via REST APIs. You use Javascript to write the script which runs on the server. You don’t need to worry about deploying or running any servers, all is done in the Appery.io cloud. An example is the best way to show it, so let’s do that.

To keep the example simple, let’s say we wan to build an API (script) that takes a developer’s name returns a greeting and also returns the time when the greeting occurred. It’s basically your HelloWorld example.

To create a new Server Code script you just need to click Create script button:

How to Create a Mobile App with User Registration [Video]

User login and user registration are one of the most common features in a mobile app. With Appery.io Database built-in user management feature, adding a login and registration capability to an app is very fast and simple. We know that developers love examples and so we published an app example that shows how this functionality is created.

To create an app based on this example is even faster. When creating a new app switch to From example tab and select Login Registration Example. Then hit Create.

This example does require a very quick setup, you need to create a database where the users will be store. Head over to documentation for setup steps.

Four Questions to Ask before Hiring an App Development Company

Like any business project, when you’re in the market for a mobile app development company, it pays to ask some important questions beforehand. Do they have the right tools and experience to meet your needs? Will their process work with your company’s process? How cost-effective and timely are they? Asking the right questions will give you a clear picture of whether the company will work best with your budget, your requirements, and your own team. In order to make the best decision for your company, you should ask these four questions.

How to Upload Files From a Mobile App to a Cloud Database

cloud_upload1

Mobile developers often face the need to upload binary files, such as images, to the database. For example, this could happen in an app like Instagram, where a user takes photos with the device’s camera and then publishes it to their followers. Of course, all the data — including images — should be stored in the database, so the user can sign in from any device and see his or or her feed.

Another possible case for uploading images is sending an MMS (multimedia message) from your app, which can be done via the Twilio API. Twilio accepts a direct URL to an image. A user takes a picture with the device and uploads it to the Appery.io database. Then, a direct image URL is passed to the Twilio API.

In Appery.io, there are three ways to upload files to the database :

  • Via Web API (this approach uses only the browser API).
  • Via Cordova file-transfer.
  • Via the Input component and JavaScript helper (It’s also possible to upload multiple files via the Input component, see this tutorial for more).

We’ve created a plug-in for the first two of these, and, with it, you can quickly implement file uploading in your mobile Appery.io app. It consists of two pages – cordovaupload and webupload. The cordovaupload uses the Cordova file-transfer plug-in. To make it work, the app has to run on the device or via the Appery.io Tester app.

The webupload page uses the browser FormData API to upload a file. This approach can be used to test the app in the browser, which is faster than on the device without having to take a picture each time. The Web API can be also used to upload images taken via the camera on the device.

A quick note about configuring the plugin: the Appery.io database requires a sessionToken for uploading files to the database. To make the plugin simpler to use, it uses the Master Key. So, to configure this plugin, you should provide the ID of the database that will be used to store files and the Master Key instead of sessionToken.

However, please keep in mind that for security reasons, we recommend you use sessionToken instead of Master Key. You can learn how to implement user authentication and registration with Appery.io here.

This plug-in is configured out-of-the-box to work with the Appery.io database, but it can be modified to work with any other API provider that allows file upload. You will need to change the upload REST API and update any parameters.

As usual, we’ve prepared a detailed tutorial for this plug-in, which you can find here.

If you have any problems with this plug-in or with file uploading in Appery.io, contact our support and they will help you right away.
