"Comprehensive exterprise framework"

3.5/5

What do you like best about Ext JS?

I like that it offers a multitude of tools and examples, and it has excellent documentation. I also like the WYSIWYG editor. Review collected by and hosted on G2.com.

What do you dislike about Ext JS?

It's a very large framework, and unless you have a very streamlined development process, you may wind up including way more than you need to have a functional site. Also, it is very expensive, which makes it difficult to recommend for smaller projects. Review collected by and hosted on G2.com.

Recommendations to others considering Ext JS:

It's a very comprehensive enterprise-grade framework with excellent support. It scales well, and can be used for a variety of tasks, including collecting data, visualizing data, and building rich user experiences quickly and effectively. Review collected by and hosted on G2.com.

What problems is Ext JS solving and how is that benefiting you?

We are not using ExtJS in my current organization. In my previous organization, we did use it, and I was able to build many useful tools with it. Review collected by and hosted on G2.com.

"Ext JS is a good platform "

4/5

What do you like best about Ext JS?

Designed to be used for enterprise applications, support, and Professional Services are all available from Sencha, the components structure will be very clear and will make developers good documentation and tech support.

Sencha builds several tools designed just for Ext JS. This means things like code completion, debugging, testing tools are all designed just for the framework; leading to a superior design, development, and testing experience Review collected by and hosted on G2.com.

What do you dislike about Ext JS?

Slow learning curve,

expensive enterprise license Review collected by and hosted on G2.com.

Recommendations to others considering Ext JS:

Ext JS 6 is designed to allow creation of desktop and mobile applications. If you decide to convert your desktop application to a web or hybrid mobile app with an iOS or Android native look and feel, you will need to write very extra little code. Review collected by and hosted on G2.com.

What problems is Ext JS solving and how is that benefiting you?

thanks to sencha architect structure the code structure is understandable by the whole development team Review collected by and hosted on G2.com.

"Powerful framework for applications with an extensive user interface"

4.5/5

What do you like best about Ext JS?

Very rich framework of UI components; reliable / very few problems; works well with other JavaScript libraries; good support for building and testing; great set of examples online. Review collected by and hosted on G2.com.

What do you dislike about Ext JS?

Not a negative per se, but we have not used ourselves the "data store" facility in Ext JS that transfers data between server and client -- for other applications this may be a key feature. Review collected by and hosted on G2.com.

"Great framework to work with, small community"

4.5/5

What do you like best about Ext JS?

The framework is complete as a whole, I've been working with it for more than 10 years which gives me a big advantage on others Review collected by and hosted on G2.com.

What do you dislike about Ext JS?

but the community is so small that we are always fighting to promote it to being used against react, angular, vuejs, or other frameworks. Review collected by and hosted on G2.com.

Recommendations to others considering Ext JS:

It's worth the time and investment if you are looking to go deep in front-end apps. If you are looking for superficial features, might not be worth it. If you need strong framework to build upon, it's great! Review collected by and hosted on G2.com.

What problems is Ext JS solving and how is that benefiting you?

Not having multiple third parties tool to build a software. I can use 90% of ExtJs to build my app and get small amount of third parties to finish what is not supported. Accelerate development time, lower maintenance cost. Review collected by and hosted on G2.com.

"Sencha"

3.5/5

What do you like best about Ext JS?

It’s very versatile and dynamic. Binding is done well, and is a MVVC or MVC style. Easy to learn and great documentation. Loved that I could use easily for mobile development, bundled packages well. Review collected by and hosted on G2.com.

What do you dislike about Ext JS?

No one uses it or has heard of it, and it’s expensive. It has options to incorporate other modern languages like reactjs but then why wouldn’t we be able to just use reactjs instead. The releases of new versions were few and far between. Didn’t use modern JavaScript conventions. Review collected by and hosted on G2.com.

"A great framework, which could be event greater!"

4/5

What do you like best about Ext JS?

A full-app framework, which covers fairly well, desktop and mobile needs.

A good/powerful class structure, good documentation. Review collected by and hosted on G2.com.

What do you dislike about Ext JS?

The community is shrinking, the license/price policy is contra-productive, not well fitted for freelancers.

It's too expensive for developers to try to learn it by their own. Due to this, man power is limited.

The provided tools and suport are fairly terrible. Review collected by and hosted on G2.com.

"Great JS framework with a long learning curve to take advantage of it"

4/5

What do you like best about Ext JS?

JSON based descriptions, crud based on model and sessions, capabilities to generate complex crud applications, UI components Review collected by and hosted on G2.com.

What do you dislike about Ext JS?

Look and feel not in the standards, requires advanced programming skills and long learning curve, poor dashboards management Review collected by and hosted on G2.com.

Recommendations to others considering Ext JS:

Good framework but needs a long apprenticeship if you want to really take advantage of it. Review collected by and hosted on G2.com.

What problems is Ext JS solving and how is that benefiting you?

Once figured out the CRUD based on models and sessions allows us to build complex applications based on JSON descriptions. Gain of productivity, maintainability...

Dynamic package loading for mashup applications Review collected by and hosted on G2.com.

"Everything you need for building web based enterprise applications"

4/5

What do you like best about Ext JS?

Components for everything you can think of necessary in a modern framework, decent multi device/browser support and a very good class structure Review collected by and hosted on G2.com.

What do you dislike about Ext JS?

The recent updates have not had that much content and the set up can be quite tricky at first Review collected by and hosted on G2.com.

Recommendations to others considering Ext JS:

Excellent framework, but very expensive Review collected by and hosted on G2.com.

What problems is Ext JS solving and how is that benefiting you?

It's surprisingly good at handling lots of live data and using their data structures to deal with our own database models. We can easily build and extend our own framework on the existing framework. Review collected by and hosted on G2.com.
