My perspective of working with the Ionic Framework

This post is more than 2 years old.

For a while now I've been praising the the Ionic framework as one of the coolest things to happen to Cordova/PhoneGap development. I kept promising to talk about it a bit more deeply on the blog and today I've finally gotten around to it. This will be somewhat long, and rambling, but I hope it will give readers an idea of why Ionic is so cool and why they should consider giving it a try.

Let's begin by talking about what the framework actually is. I'll steal their marketing tagline as a jumping off point:

Free and open source, Ionic offers a library of mobile-optimized HTML, CSS and JS components for building highly interactive apps. Built with Sass and optimized for AngularJS.

Ok, cool, so let's break that down a bit.

First and foremost, Ionic is not just another UI framework. Not that there is anything particularly wrong with that; I love UI frameworks as they are a simple way to make my demos look nicer, but Ionic is much more than this. To be clear, there is a UI part to the framework and in theory you could use just that aspect, but you would be missing out on a significant part of what makes Ionic great. You can see plenty of examples on the site itself, but here are a few samples I stole from the docs. First, a Card view:

And here is a list view:

You can see more examples on their components page. Basically - a nice clean, perhaps Bootstrap-ish, look to it.

The next major aspect of Ionic is that it is "optimized" for Angular. When you work with projects (and I'll talk a bit more about that experience later), your initial code will be an Angular project, so if you are using Ionic, you can pretty much assume Angular as well. Do not let that be a blocker for you. If you read my blog regularly, then you know I've recently started working with Angular again. I'm very much at the newbie level where I can get stuff done, slowly, and the code is ugly, but it works, and that makes me happy. So speaking as an Angular noob, I felt comfortable using Ionic with it. What problems I did have came more from my lack of experience and never actually stopped me from working. Of course, if you know nothing of Angular, you may want to spend a few minutes looking at it before you use Ionic, but you certainly do not need to be an expert.

Ionic provides multiple different directives for your Angular app, making those nice UI things like the cards and lists somewhat easier to use. Oddly, these are found in the JavaScript portion of the docs, which doesn't quite make sense to me, but that's where you'll find them. There are also times when the docs about the directives are not quite as clear as the pure CSS side. As an example, when I looked at the documentation for ion-list, it wasn't clear how I was supposed to build an inset list. The CSS docs made it clear, but I didn't get how to translate that to the directive version. The solution was pretty simple (add class="list list-inset" to the directive), but it seems like that should have been more clear.

On top of the UI support, there is also strong UX support as well. By that I mean common UX metaphors like pull to refresh are easy to add (ion-refresher) via directives. Other examples include scrollable panes and even my favorite (not), infinite scroll. Basically, all the "typical" UX things you may need in your app are baked into the framework and are pretty easy to use, again, even with me being new to Angular.

The final major aspect of Ionic is its use as a platform to build Cordova (PhoneGap) applications. Again, you don't need to use it for that, but the main Ionic tool (the CLI) is wrapped around working with Cordova projects. You can, of course, skip this and use the UI/UX components in a mobile-optimized web page or in some other hybrid application, but the real treat here is for Cordova developers. When you mix this with the sister project ngCordova, the combination becomes even more powerful.

Ionic has a CLI that can be used to create a new project. It also wraps Cordova CLI commands. So for example, I can start a project with the Ionic CLI and work with my platforms and plugins as well. I can also fire off a call to the emulator from it.

Now - my first impression of this was that it was nice to have a good way to seed a new Ionic project, but that I probably wouldn't use it much after that. On a whim though I took a look at the ionic serve command. Cordova has a similar command. The idea is that it fires up a HTTP server so you can test your code in a desktop browser. That's handy. But there are a number of problems with this feature. First off - you can't use the "core" www as is. You must do a build first to copy assets into an appropriate platform folder. You can get around this with Grunt of course (see my example), but it isn't necessarily ideal.

Ionic's serve command handles this much better in my opinion. First off - it allows you to edit code in www and see it reflected immediately. And by immediately, I mean immediately. Upon running ionic serve ios, the CLI will actually open a new tab for you, load your app, and constantly monitor your file system for changes. As soon as you edit something, it automatically reloads the tab. Again, this is all stuff you could do with Grunt, but Ionic has it out of the box.

So, that's a lot of talk about what Ionic is. Now let me switch gears and talk about the project I built. Please note that I'm attaching the entire project as a zip attachment to this blog entry. But more important than that, please remember I am new to Angular and Ionic! What you will see here is most likely not optimal code!

For my project I decided to rebuild my INeedIt application. This is an application I've built a few times now. First in Flex Mobile. Then Backbone, and most recently in Angular back in January of this year. The application is rather simple. It figures out your location and then uses the Google Places API to let you know what businesses are nearby. My most recent version used Ratchet for a UI framework. Since the previous version was built in Angular, I was curious how much would directly port over and how much I'd need to tweak for Ionic.

For the most part, my Controller layer did not change at all. I did switch to using a StateProvider, which isn't an Ionic thing but an Angular thing, and while a bit weird at first, it kind of makes sense now. Smarter folks than me said this is the "right" way to do routing in Angular and I'm fine with that.

The real changes were at the view level. I removed all calls to Ratchet's CSS and began building as much as I could with Ionic. In general, this wasn't a big deal. As I mentioned above, sometimes it was a bit difficult to figure out the right CSS arguments for a directive. Also, Ionic has bugs. Shocking, I know, but for example, my list view needed to include some additional code to work around inset lists being broken. Here is that list. Note the div essentially replicates the ion-list tag.

<ion-view title="INeedIt">
		<div class="list list-inset">
		<ion-list class="list list-inset">

			<ion-item ng-repeat="service in services" href="#/service/{{}}">



Of course, the nice thing about working within Angular is that as soon as this particular bug is fixed, it will be trivial for me to yank it out. Also, I was able to use the Ionic Support Forum to quickly find the issue and the workaround. I had a few problems while working on my application and the response on the forum was - on average - very fast and polite. Heck, even when my issues were Angular-based, not Ionic-based, I got great support. (Not that I'd abuse it, but it is nice to know that the folks there recognize that developers like me may run into issues that subtly cross the line from their responsibility to general Angular issues.)

Let's take a look at the screens. The initial screen is temporary while your location is loaded. After that a simple list of services is provided.

After selecting the service type, the Places API will then fetch results based on your location. Yes, these are real restaurants located near me.

When a business is selected, I show you details of the location. I decided to make use of Ionic's card view here and a cool slider gesture for pictures. Here is an example.

If you scroll down a tiny bit, you'll see that you can swipe those pictures left and right to see more of them.

How difficult was that part? Check out the code below.

<ion-slide-box show-pager="true">

    <ion-slide ng-repeat="photo in">
        <img ng-src="{{photo.url}}">


Yes, that simple. I love that!

So, long story short, after being impressed with Ionic, I was happy to get a chance to build a "real", if simple, project. And while I definitely ran into hiccups, I'm more impressed now. I strongly urge folks to give it a shot and let me know what you think in the comments below.

Did I read that right? iOS development is restricted to OS X for the time being?

Comment 2 by Raymond Camden posted on 7/28/2014 at 10:40 PM

Yes, but that isn't an Ionic issue, it is a Cordova issue. You can't build to iOS from Windows. You *can* use PhoneGap Build to do so of course. So you could use Ionic, do most of your work in the browser, and send stuff to PGB for iOS builds.

Another excuse to get a Mac :)

Comment 4 by Phil Duba posted on 7/28/2014 at 10:53 PM

Nice write-up Ray. I've been doing some prototype apps using Ionic and since we're moving into more AngularJS development for our web apps, this seemed like a natural progression for mobile apps and I'm finding that to be the case.

Comment 5 by Raymond Camden posted on 7/28/2014 at 10:56 PM

@Robert: I know that is said tongue in cheek, but I honestly agree with it. If you want to develop for iOS, you really want to get a Mac. Heck, you can always get one of the cheap Mac minis and just use it as a secondary system. I've got nothing against Windows, I really like it, but OSX has long felt more developer friendly to me. But again - if you want to stick with Windows, go for a cheap mini.

Comment 6 by Adam Presley posted on 7/29/2014 at 12:11 AM

It's good to see the framework love. I just took a look at a few frameworks that are Cordova friendly, and I have to say that Ionic really has got it together. Nice stuff Ray.

Nice write-up. I appreciate the technical pros/cons. There is so much going in this space it’s tough to stay on top of it all and make informed decisions. I’m still at the research stage to find the right dev environment for my app which ideally will be deployed on mobile (iOS, Android). Native like performance is a big criteria for my app (a productivity app) and it's one that I don't see ionic tackling very well at this moment. Neither do they provide a build service. With the limited research I've done, the apps I've seen from ionic seem pretty trivial. I'm looking at ionic however, as well as Appgyver Steroids. Steroids seems to have a more complete platform offering a build service, and actual native performance on some levels (using a multi-page architecture for transitions and easier debugging). In addition, they employ ionic as their default UI framework and their generators user Angular. It will be interesting to see where these two go and if they go head-to-head.

Question: Have you looked at AppGyver Steroids?

Comment 10 by Raymond Camden posted on 7/29/2014 at 3:44 PM

@Bill: To be fair, why would they do a build system when, if you have Cordova, you can already build locally? Or you can use PhoneGap Build?

Of course, they are doing so anyway. ;) I'm looking for "proof" but I think it was in their last newsletter.

I'm not seeing any performance issues, and I know they are thinking about it as they built a very specific list control just for that reason, but obviously I've not tested with a very large app.

As for debugging with Ionic, you have the same options as you do with Cordova, which is *very* rich.

Comment 11 by Ernest Leitch posted on 7/29/2014 at 8:21 PM

It's cool to see examples of different mobile frameworks. When I started a project for work I chose Sencha Touch 2.x because I heard good things from another developer that worked with it. The learning curve was steep but I'm happy with the final output.

Like any mobile framework it's not perfect and it's gated with expensive support if you run into a huge problem. I was able to figure out 99% of my issues with google, source diving and forum searching.

Seems like a good time to be a mobile developer. Lots of options.

Comment 12 by Matheus Rocha posted on 7/30/2014 at 7:49 AM

This is a very good post, I am using Ionic too, I saw you making some questions on the ionic forum, but I am a newbie with it too, so when I found the answer for you, somebody already reply. I like the ionic community too, they always wanna help. I think Ionic it's a real "bad a** framework" like they say in their page.

I am very excited to test the Ionic Creator, did you saw their page about it?

Comment 13 by Raymond Camden posted on 7/30/2014 at 4:08 PM

@Matheus: I did. In general, visual builders don't interest me much, but I do plan on trying it when I can.

Comment 14 by Michael posted on 8/21/2014 at 3:26 PM

This isn’t bad, a little bit clunky and it’s still got nothing on Native. You should check out Xamarin you’ll be able to develop much much better apps than this.

Check out this app, it's leagues ahead: http://www.michaelridland.c...

Comment 15 by Raymond Camden posted on 8/21/2014 at 3:52 PM

Well, I don't think it is clucky. I'm firmly in the camp of thinking that hybrid is a good solution, but we may have to agree to disagree. ;)

Comment 16 by Sameer posted on 10/17/2014 at 8:00 PM

Thanks for the nice writeup here. Can you recommend between ratchet and ionic as better ui framework based on your experience? I am confused between two? Did you hear or tried angular material?

Comment 17 by Raymond Camden posted on 10/17/2014 at 9:08 PM

I only use Ratchet once for a small demo so I can't really say I can fairly compare the two.

Comment 19 by Gabe Sumner posted on 12/24/2014 at 2:35 PM

Telerik's AppBuilder will enable you to build PhoneGap/Cordova apps for iOS without a Mac - - It's also fully compatible with Ionic Framework.

Comment 20 (In reply to #19) by Anton B. posted on 1/14/2015 at 1:36 PM

@Gabe Summer

You can build iOS PhoneGap/Cordova apps using just about any tool and any operating system you want. Up until a point, that is when you want to test it on a device and deploy it. Then you have to buy a Mac. I don't think there is any way around that at the moment.

I believe the most complete development environment at the moment is Visual Studio 2013 with the Hybrid App tools. Visual Studio is entirely free, it has, by far, the best emulator for Android, and it will debug your app on your Mac/device when you get one. You'll have to get one.

Comment 21 (In reply to #15) by Anton B. posted on 1/14/2015 at 1:43 PM

Hybrid is a viable solution for simple apps, but I have worked on some stuff that is not entirely simple, and we had to abandon both basic Angular+HTML and Ionic for performance reasons. I believe this is at least partly an Angular issue, and it is being worked on actively by the Angular team, but probably only for Angular 2, which is a complete re-write of (and totally incompatible with) Angular 1.x. When I say totally incompatible with, I mean "none of your code will work at all, and there is no upgrade path" incompatible.

For complex data-driven apps, I have found only two viable cross-platform solutions for mobile and that is Xamarin and (aaaahhhh, gulp) Flex. And perhaps doing it in pure Javascript no major framework (I'd rather shoot my self in the knee) I'd love to hear about alternatives.

Comment 22 (In reply to #10) by Anton B. posted on 1/14/2015 at 1:50 PM

As I say in a post below, we have had major performance issues with Ionic and also with "barebones" Angular. It seems the Ionic team is working hard on performance, and hopefully they are tight with the Angular team. At the moment, Ionic is not an option for us though, and it probably won't be for a while. That means Ionic is out at least until mid-2016 or so, probably end of 2016.

The reason it is out for so long is that obviously we could do stuff on Ionic at the moment, and assume performance increases in both Angular and Ionic, but since all the code we eventually did in an app now would have to be thrown away when migrating to Angular 2, we have to assume the same would be the case for Ionic. In other words, there is no point in doing Ionic apps until Ionic is on Angular 2 since Angular 2 will require not only a complete re-write of my Angular apps, it will certainly require a complete re-write of Ionic.

Comment 23 (In reply to #9) by Anton B. posted on 1/14/2015 at 2:07 PM

@Bill, We've worked with AppGyver as well for our LOB apps, and it has some of the same problems as Ionic/Angular+HTML/Etc have. Performance suffers noticeably as the complexity of the app increases, and we saw, at times, pretty bad performance as the number of bindings went past the trivial. For us that has meant doing native apps at the time, while investigating stuff like Xamarin. We have found that Xamarin gives the performance we require, so going forward we are using that for our new offerings. Xamarin Forms does not suffer the way the JS frameworks do as the number of bindings go up. BTW, on web-apps used from a PC, this is not an issue at all, so we use Angular there all the time.

Checking with the Angular team, I have a high confidence level with regards to their fixing performance issues on mobile, it is a high priority for them it seems. The problem is (as I say below) that this is for the Angular 2.0 re-write scheduled for release about a year from now. Since the re-write is entirely incompatible with Angular 1, so we see no point in doing anything Angular on mobile until 2016. It's a pity, we'd love to have our mobile and our standard browser-based stuff on similar platforms.

As for build and test of Cordova/Ionic/AppGyver/Angular... apps, astonishingly I now find Visual Studio to be better than anything else. We've had a couple of guys evaluating this stuff, and it is awesome. Build, debug all of that stuff works (with a few hitches, the build system is a technical preview) amazingly well. Debugging on iOS devices, on Android devices and the new Android emulator for Microsoft, which is heads, shoulders, torso and half a thigh better than the Google Android emulator. I wish the Google stuff was half the quality of Microsoft's current beta dev environment.

"You can build iOS PhoneGap/Cordova apps using just about any tool and
any operating system you want. Up until a point, that is when you want
to test it on a device and deploy it. Then you have to buy a Mac."

Actually, I believe the opposite is true. Using things like the PhoneGap Desktop app and PhoneGap Build, you can test on an iOS device and develop on a PC/Linux machine. To "build" though it must be a Mac, if we are talking about generating an IPA file to send to a device.

Comment 25 (In reply to #23) by Harri Sarsa posted on 1/15/2015 at 2:23 PM

AppGyver dev here! I'd love to hear more about your specific problems, as we've been able to build quite complex apps with satisfactory performance. If you have time, please drop us a mail at

As for performance of AngularJS in hybrid apps – it's not hard to write bad performing AngularJS code, so a lot of time the big performance hits come from suboptimal coding (not implying that was necessarily the case with you guys). In any case, we're really looking forward to seeing how Angular 2.0 improves performance, as well as it being elevated to a full UI framework too with Material Design.

In any case, I just want to drop off with the note that Supersonic (which replaces the old Steroids.js) is platform agnostic – while the default projects utilize AngularJS, all the core functionalities are really independent from any frameworks.

Comment 26 (In reply to #25) by Anton B. posted on 1/16/2015 at 10:38 PM

Hi, thanks for answering me. During this phase I was working on Angular only and later Ionic, not AppGyver. I can therefore only repeat what they said in our discussions and after asking them.

The main problem, as I understand it, was performance on Android. Our requirements was that performance on mid-end devices was good, and we could apparently not get satisfactory performance on several devices, for example the Galaxy SIII.

I do understand that performance on Android has been a focus, so that may no longer be a problem, but we've since moved on. Obviously we are regularly revisiting tools options, and it's a guarantee that AppGyver will be in our next round of testing. Probably this summer (lower pressures in the summer, more time to "play around").

Comment 27 (In reply to #26) by Harri Sarsa posted on 1/19/2015 at 1:46 PM

Good to hear! Android performance is definitely something that has improved a lot (not sure when you were testing, but we for example rewrote the whole Android client from scratch last year). I hope you find everything satisfactory when the next round of testing comes around!

Comment 29 by Vinod Shintre posted on 1/21/2016 at 2:33 PM

awesome. it took me just 2 weeks to build a sleek & stable ionic based app & certainly my perspective towards ionic/cordova has changed for good. :)

publishing this app at soon for you to evaluate if my claim holds good.

Comment 30 by Quentin Seven posted on 6/24/2019 at 10:53 AM

My personnal experience taught me that Ionic 4 is a bad the WORST framework ever made, it's unstable as hell.

I'd share that feedback with the team and not on my (near) 5 year old blog post. :)
