Android/iOS app with Django as backend

Question

I have a website project built in Django and want to build a mobile app for it. I did a lot of research but was confused between native and hybrid app. My project is basically a Quora clone and just a college project. I also saw PhoneGap, Ionic and Sencha but I am really confused about how they all fit. Do I have to use Ionic with PhoneGap or Apache Cordova or just Ionic? What is the structure and where should I start?

Answer 1

TL;DR: Start with Ionic. Ionic uses Cordova "under the hood". No need for PhoneGap or Sencha, so don't be confused by that.

Disclaimer: This will sound like advertisement, so I have to say I'm in no way affiliated with Ionic, I just happen to like it so much that I'm sharing the love for it.

Let's take this one step by step:

What is Ionic?

Ionic is a framework for building hybrid mobile apps, and it's built on an ecosystem that includes Angular as the web application framework and uses Cordova for the building and packaging of the native app. Ionic creates a native mobile app that can be installed via the app stores, and contains what is called a WebView (essentially an isolated browser window) with a JavaScript API inside which the web application will run.

What is hybrid mobile app?

If you're a web developer, you have a decent knowledge of HTML, CSS and JavaScript. Also, you're most likely using one of the ever so slightly popular frameworks these days like AngularJS. Up until fairly recently if you wanted to make an app for (currently) two most popular mobile operating systems iOS and Android your only bet was to make the so-called native applications using the SDKs of the intended platform itself. This, of course, meant that you needed to make two versions of your application - both for iOS and Android. If you are a solo developer chances that you're proficient in both are not so high.

Nowadays, luckily, with the Ionic Framework you can create one application by using the skills you already have as a web developer and then deploy this one codebase as an app to both iOS and Android stores. How cool is that, right? So, hybrid because it's a "simple" web app wrapped inside the native app with a so-called WebView.

Why is Ionic cool?

Ionic is awesome because it's not "just" a framework. Instead, it has a whole ecosystem built around it. For example, Ionic allows you to:

• generate icons and splash screens for all devices and device sizes with a single command: ionic resources. This alone saves you at least a day of image preparing for various sizes.
• instantly update your apps with code changes, even when running directly on your device with ionic run --livereload
• build and test iOS and Android versions side-by-side and see changes instantly with ionic serve --lab
• share your Ionic apps with clients, customers, and testers all around the world without ever going through the App Store with ionic share
• easily accessing the full native functionality of the device using ngCordova (here you get to use any Cordova plugin - so Ionic is indeed much more than Cordova per se)
• Also, they're (Ionic team) building a full-stack backend services and tools for your Ionic app like Deploy (for deploying a new version without going through Apple review process!), Analytics, Push notifications.
• Ionic CLI (command line interface) uses Cordova in the backend and allows you to build (directly using Ionic CLI) apps for iOS and Android (you by doing ionic build ios or ionic build android and woila)
• Ionic uses Angular as a frontend framework so if you're familiar with it it will come as a bonus. They're working closely with the Angular 2.0 team too.

How to start your project?

If you take a look at my answer to this question you'll see that if you already have an API defined in your Django backend, then you can start using it quite quickly by leveraging the existing API and consuming it with Angular $resource.

Hope this helps and that you find using Ionic a pleasure.
