Ext JS Reviews & Product Details

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.

Ext Js is one of the most powerful tool for UI development out on the market. One aspect of Extjs that differentiates itself from the competition is its vast array of components that can be used in development and eliminates the need to install other packages that could potentially cause compatibility issues in the long run. Furthermore, Ext js is completely packaged on npm and can be easily deployed in a linux container on a kubernetes infrastructure. Review collected by and hosted on G2.com.

Ext Js has a steep learning curve for any new developers. However in order to remediate the issue, Ext Js has an extensive documentation with detailed examples which helps to facilitate the learning process. Furthermore, Ext Js community is very small which makes it hard to find solutions to issues quickly. But again, Ext Js remediates this situation with credits in order to have access to the support staff quickly Review collected by and hosted on G2.com.

I like that the UI is quick to put together with all the widgets that come with almost every function and configuration you need.

I almost never have to write html and css. The themes work great. So I can really spend my energy on writing the business logic and functionality.

Great Documentation too. Review collected by and hosted on G2.com.

1. The license is expensive so it gets hard sometimes to convince others to pick ExtJS when deciding stack for a new project.

2. Support can be a bit challenging at times. Review collected by and hosted on G2.com.

Ext JS is the best tool available to accelerate the construction of web and mobile applications, providing the best organization so that a team can work with the highest performance available, a feature that highlights much of this tool is that it offers pre-assembled containers and capture fields for forms, buttons, menus and graphics very complete to develop applications with high levels of professionalism, this system is the most solid structure with which you can work a programmer incorporating some software engineering methodologies, the utilities that provides this system I must say that are excellent for the construction and testing processes of the software implemented. Personally in all the years that I have been working in my profession I have experience working with several services similar to Ext JS and I must say that this system is the one that has provided greater efficiency to my company at the time of implementing and maintaining all the applications we have built in recent years. Review collected by and hosted on G2.com.

The performance provided by Ext JS I can certify that it is very good, we have never had problems with the software and has been a very good experience its implementation in our company. I think that for amateur programmers it can take some time to get used to working with this system, but with all the experience I have using different similar services in the past this tool is very easy to use compared to others.

All of the built-in UI components make developing applications so much simpler. The data grid is full-featured, easy to use and allows you to easily present data in the app really quickly. The ViewModel concept is also great and can save a lot of development time in various ways. Also, specific to my organization, the Ext Direct functionality has been extremely useful.

As I see it, the greatest drawback to the framework is having no control over the html markup. Yes, you can assign classes, but to not be able to see anything on the front-end until runtime definitely took some getting used to. Also, I think it's silly to have to code essentially two separate UIs (modern and classic) if you want to have a responsive application. Review collected by and hosted on G2.com.

The framework is incredibly well structured and the object oriented approach to building and extending components sets this framework apart from the rest. The API documentation are incredibly detailed and the examples are always a great starting point. Review collected by and hosted on G2.com.

Our team stopped using CMD. Almost all of our applications are internal and the complexity of building and troubleshooting minified JS vs. the value or performance gain was simply not worth it. If Sencha would stop promoting CMD as the defacto approach, I think they would be able to greatly reduce the learning curve, which is often a barrier to wider adoption.

Most of all I like data management, you can manage very big and complex databases using Model-View-Controller architecture and simplyfied class like store, proxy, and so on. It is very easy to create fully responsive html5 based interfaces without takes care of what kind of browser the web app will run on. Sencha Themer helps you to build and customize you components aspect to make users experience and web navigation very friendly and cost-effective, without write a single row of any css file. The whole framework is fast and efficient.

Sencha support is very fast and accurate they always help you providing working examples and suggestions. Review collected by and hosted on G2.com.

Documentation laks of examples, there are some unlinked links and many features aren't fully documented. Furthermore I wrote to sencha support for help and found many issues in the framework that in new release aren't solved after 3/4 months.

Moreover I think that in some components misses events and features, for example in grids or export component. Review collected by and hosted on G2.com.

Ext JS helps to build components stack faster and the re usability factor helps to build a complex web application development faster. A structured approach helps to add external libraries easy to use, and a rich in-built components store reduces need to create custom components. Review collected by and hosted on G2.com.

This framework isn't widely used as other frameworks. Which, when comes to putting a question, not many developers having faced the issue, makes it difficult to reach a solution. Review collected by and hosted on G2.com.

The data layer of ExtJS is very powerful.

In a short amount of time you can get your web application up and running with connection to a REST server, elaborate and display data in different kind of views. Review collected by and hosted on G2.com.

If you have to customize the views with custom CSS it's a pain because the dom produced by ExtJS it's over complicated. Review collected by and hosted on G2.com.

It build JS automat based on OO structure. Also was very easy to puck up tuturial and learn how to use in about 2 weeks for js folks Review collected by and hosted on G2.com.

Not having no control over the html markup makes it a bit of a challenge to produce a nice looking webpage, takes a bit of work to get that working. Review collected by and hosted on G2.com.
