Overall Review Sentiment for Ext JS

I like ExtJS because everything is built in and I don't have to rely on third party libraries. For example, I can build a fully fleshed out grid in only a few lines of code.
I like that the documentation is thorough and there are a lot of examples of ways to build different UI components using the kitchen sink. Review collected by and hosted on G2.com.
I wish there was some better support for integrating third party libraries like custom charts. I wish there was some more support for the paid version of font awesome. Review collected by and hosted on G2.com.
The level by which complicated systems can be created. Elements can be used in a complicated, functional interface for minutes. The whole suite has a coherent look that appeals to customers, and it is straightforward to customize it using both Sencha Themer or Cmd's SASS compilation characteristics. Both practical features can be readily modularized, the proposed MVC (or recently MMVC) composition and operation templates make the organisation of code a doddle, so that each code file can be maintained to around 100 top forwards with the correct organisation, which makes code quite straightforward and similarly knowledge its structure.

The selling prices is a bit excessive, glitches can be hard to detect and sometimes elements, particularly the HTML editor, are hard to work with. Review collected by and hosted on G2.com.
When I started working , I searched through web to find out the pros and cons of Ext JS. My Initial assumption was that it is not worth it. But after using it personally for my work I found out that It is very useful and has lot of unique features. This is very user friendly. The things which I liked the most are:
1. The UI interface is really good.
2. It provides support to lot of web functions (MVC, REST)
3.The documentation for all the versions( Makes lifer very easy for users)
4. HTML is not required at all Review collected by and hosted on G2.com.
It is good but not the best I say, This has some cons (not very big though).
1. Pricing ( This makes life easy but the cost is relatively high)
2. Customer support issue Review collected by and hosted on G2.com.
The components are all acting the same, using the same vocabulary so it is easy to understand and know what to expect whatever component you are using. But what I like most with extjs is the very detailed documentation combined with other helpful users sharing their fiddles. Review collected by and hosted on G2.com.
When you want to do/solve something unexpected that is obvious to you and don't find others with the same problem. Or when you google somethin and most of the answers you find are related to an older version. Review collected by and hosted on G2.com.
The speed with which complex applications can be built. Ready to use components take minutes to put together into a complex, functional UI. The entire suite offers a consistent look which appeals to clients and customizing it with their own branding is very simple using either Sencha Themer or simply through the SASS compilation features provided by Sencha Cmd.
All functionality can be easily modularized, the framework's suggested MVC (or more recently MMVC) structure and the project template they provide makes organizing code a cinch and with proper organization each code file can be kept to around a 100 lines tops, making browsing code very simple and understanding its structure similarly simple.

The pricing is a little steep for single developers, sometimes bugs can be difficult to track down and certain components can be difficult to work with at times, especially the HTML editor. Review collected by and hosted on G2.com.
ExtJS allowed us to build a highly adaptive front end to an enterprise Workflow Management platform - using a library of industrial strength, robust widgets, without having to be concerned with cross browser weirdness. The touch support is also reasonable, given that we didn't initially target touch at all - we basically got most of it for 'free' as it was provided natively in ExtJS Review collected by and hosted on G2.com.
Upgrades have sometimes been quite significant, including many breaking changes. This makes 'keeping current' somewhat expensive and somewhat daunting. Review collected by and hosted on G2.com.
In my company (Ethea S.r.l.) we uses ExtJS from version 3 to build our web builder tool named "Kitto", made with Delphi.
ExtJS had a complete suite of components so we don't need to search and integrate different libraries: for this reason it was very simple to make Kitto because every component (grid, menu, toolbar, panel, form, etc...) works in the same way and Kitto build Javascrit automatically based on a object oriented structure. Another good reason is that Ext JS is a suits of classes with strong inheritance and a way to build GUI in an elegant and simple way. Review collected by and hosted on G2.com.
The only problems that we encounters was the gap from ExtJS 3 and ExtJS6: for this reason, Kitto2, based on ExtJS6 was partially rewritten because of the change of the undeline javascript library. Review collected by and hosted on G2.com.
For me the best thing in ExtJS is that it's powerful and flexible. The documentation is very good, lacks some advanced insights on the components internals but overall is very good.
The fact that you can inspect it's code is also a plus since many times you can discover more over it's internals.
The set of ready to use components is very good as well. Review collected by and hosted on G2.com.
First of all, it's a very expensive toolkit when compared to other tools available today (most of them open source). If you have a larger team it becomes cheaper to use open source tools and built your own components. In some very specific contexts this may not be true though.
Another huge issue with it is the learning curve. It has been 3 years since I stopped using ExtJS professionally so this may have changed.
Nonetheless it's the tool with the hardest learning curve that I ever worked with. Generally only good to excellent developers end up fully understanding it, the average and down developers have a very hard time on learning it since it has very specific characteristics and it requires deep knowledge on JavaScript.
Personally it is not a big deal for me, but as a business man and a manager, it's hard to find developers to work with it. Plus the average cost of those developers is higher than if you use pure React for example. Review collected by and hosted on G2.com.
