Are there any advanced apps that are built using fabric js? - performance

I got lots of simple apps or examples that are built using Fabric.js.
Can I use Fabric.js for making advanced applications? I want to check some apps and see it's performance so that I would confirm that Fabric.js can handle big apps too.

We built Fabric specifically to power design editor on Printio.ru. It's used by 1000+ visitors daily.
From other big sites there's easel.ly — visual themes creation tool. Also mywallsticker.de, scrollkit.com, and others.

Large sites that using FabricJS are listed here https://github.com/kangax/fabric.js/wiki/Who%27s-using-Fabric

http://printio.ru/ is the one of best one, what kind of advance apps you are looking for ?
check out the discussion on google groups

What are good analytic tools for Xamarin Forms?

I am looking for a way to track the navigation process of my users, as well as the number of clicks/user for each view, average screen time per/day/user, and so on.
I know I can do this programmatically but it doesn't seem like the ideal solution.
Is there any software that covers all of this?
Visual Studio App Center provides multiple useful tools. It offers real-time diagnostic data, tracking of usage patterns, user adoption and a lot more engagement metrics with App Center Analytics. You can even use custom events to get the exact user behaviors you are looking for.
I've been using it for a while and so far i'm satisfied.
AppCenter is the easiest to integrate with, it also allows you to export the data to ApplicationInsights on azure to do more with that data. There are some other options like Google Analytics (You have to install nugets on platform projects and implement them separately). You also have segment If you are interested.

How to make apk from base without using third party app?

I am planning to create a smartphone app for my website. I've searched everywhere, but it seems like all suggest to use apps, like andromo, appmaker, and more.
While I want to start from the bottom, it's harder not the important thing I can know what frameworks are needed so I become more free if I want to change or add style according to my will.
Like when creating a website, I prefer to organize HTML templates manually, than using CMS wordpress or others. So I think you guys have understood what I mean.
So, can I do that?
All the answers must be appreciated, and I thank you for that.

What's the easiest way to make a real-time chatting app with Xamarin?

I'm trying to figure out a way to create a real-time chatting app with Xamarin and some kind of backend technology. How can I do it?
I have a better solution. The above-mentioned technologies(buddy SDK & SignalR) will require you to integrate and handle everything by your self. Instead, you can go for CometChat SDK, which has real-time chat along with Audio/Video chat functionalities. Also, you can use its ready-made UI inside your application. It is the easiest & quickest way for you to make a real-time chatting system. For more information on CometChat you can refer to the following link:
https://developer.cometchat.com/docs/xamarin-forms-quick-start
As mentioned by ChristiaanV, SignalR is the way to go.
The Performance is great with Xamarin, we delivered more than 150k messages within 2 hours without any problems regarding the connection.
With Azure Mobile App and ServiceBus, you can easily scale out your backend, as described here http://www.asp.net/signalr/overview/performance/scaleout-with-windows-azure-service-bus
Have a look at SignalR, it's a good and easy to use framework to do realtime 'things'. They also have a Xamarin Component which is free to use.

Please note that I personally don't have experience with using it on mobile devices, so I can't tell you anything about how it's performing battery / performance wise.

What Software Do You Use To Create Sitemaps / Site Structure For Large Sites?

Just wondering what software you use to create a visual sitemap / site structure representation before you start big sites?
I am looking to map out a large site, but cannot find any good software to help me map the site visually (And in pages/categories)..
Maybe SketchFlow http://electricbeach.org/?p=145 ? which is included in the Expression Blend Trial http://www.microsoft.com/downloads/details.aspx?FamilyID=92E1DB7A-5D36-449B-8C6B-D25F078F3609&displaylang=en
I strongly suggest taking a look at this tool: http://www.balsamiq.com/products/mockups
The Balsamiq tool is the best for doing mockups (i assume this is what you are referring too when talking about sitemaps before you start...). With this software you can quickly generate a working wireframe of what ever you are creating. So much functionality that you can actually share it with your client to get some good sign offs prior to typing the first bit of code.
Very powerful!
And the other one...just shown at the last MIX09 is SketchFlow. Couldn't remember it to save my life. This is a WAY COOL tool for site maps and UI mock up. I was trying to find you the actual MIX presentation as it is super cool to watch. But here are some YouTube videos of that presentation from a user perspective I guess.

update...found the SketchFlow video!!! http://videos.visitmix.com/MIX09/C01F
Great keynote from there too: http://videos.visitmix.com/MIX09/KEY01
I know this is an old question, but for others who find this via search, I personally love mocking my websites up with mind mapping tools. I've tried several but my favorite was MindNode for Mac and Xmind for Windows.
XMind free download:

MindNode free download:
https://mindnode.com/
I've also tried MindMeister which works just as well as other mind mapping tools and is hosted for you so you can access your mind maps anywhere. However, MindMeister only allows you three maps (currently) without upgrading to a paid subscription.
Another that I've worked with is mockflow.com which is great for mocking up websites with all their features and buttons and even making clickable navigation. They have a free version, but again it's very limited without upgrading to a paid version.
I'm using Slickplan. This cloud based app allows me to have access to my projects from different machines regardless of their operating systems. All I need is one of the leading web browsers (Chrome, Firefox, Safari).
With Slickplan you can create visual sitemaps from scratch or you can use Site Crawler to import your existing website to visualize and reorganize its structure.
Of course you can always export your projects to the XML format, and use the exported file to create pages and menu systems inside some popular content management system - Slickplan provides plugins for WordPress, Joomla, concrete5 and a few more.

Are there any good drag&drop web app IDEs out there that support AJAX?

Can anyone recommend a GUI builder tool for creating DHTML web apps using AJAX to communicate with a web service backend? I'd like to avoid having to mess around with designing HTML, marshalling/unmarshalling data, checking for browser compatibility, etc. The tool should have a library of widgets that can be put into an application and hooked up to functionality, and be extensible enough to be able to define custom widgets. Of course free and/or open source is preferrable but I would consider proprietary tools too.
Also to what extent does the choice of GUI tool affect what platform or language I would use for the backend? If the GUI is just calling a web service then I should be able to use anything on the server-side to provide that interface but maybe some gui-side tools use a proprietary data exchange format that requires some specific server-side code?
Edit: I don't need a widget that can be dragged, I want an IDE that allows one to build a gui easily (i.e. a RAD tool).
WaveMaker is open source, runs on J2EE.
If you're comfortable with Java, maybe you could try Google Web Toolkit? http://code.google.com/webtoolkit/
I'm using Wavemaker and it does exactly what are u asking...
It is really easy to use and very perfomant....
I believe Dreamweaver does some of this, but in my opinion such editors are not a good idea. They produce horrible, unmaintainable server-side code and are quite inflexible.
Wavemaker beats everything else I have used hands down. Applications can be developed rapidly, has drag and drop, can connect to any web service, and has unmatched database management tools. The only problem with it is that it has kept changing hands/ownership so much and its future direction is not clear.
Delphi for PHP from Codegear has some of this capability, but I would agree with ceejayoz that such tools don't necessarily make for nice code.
On Dan's suggestion I took a look at GWT. I'd heard of it before but never looked at it that closely and it seems pretty interesting. Certainly it takes away the annoyance of pixel pushing and making things work in multiple browsers. I also tried searching for "gwt rad tools" and came up with a couple of results:
Instantiations GWT Designer (commercial, $59/year)
Wirelexsoft Vistafei (still in beta but will have a free and a commercial version)
I'll take a look at these but if anyone's used something else let me know.
