Ext JS provides a significant feature set with broad customization options. The framework is paramount for displaying large datasets to end users. Review collected by and hosted on G2.com. What do you dislike about Ext JS? The framework does support pick-and-choose packaging, but it's still a larger payload than competitors that provide less complex components. With that said, it's harder to select the ExtJS framework over other frameworks for smaller scoped sites. Review collected by and hosted on G2.com. Recommendations to others considering Ext JS: Use the demos to review the feature set and components available. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? We provide a comprehensive, one-stop SPA to our stakeholders that is context based on the end user's roles and permissions.

Software Engineer Small-Business (50 or fewer emp.) 9/21/2020 "Feature rich UI framework with some rich widgets" 4/5 What do you like best about Ext JS? The choice of widgets. The framework is really feature rich and has all the components that you might need as a developer like windows, panels, grid, tables, message boxes, forms and dynamic charts. The UI framework is very rich and well integrated and makes it very easy to deal with lot of Ajax functionalities out of the box. Review collected by and hosted on G2.com. What do you dislike about Ext JS? The license for using the dynamic charting components is prohibitively expensive. The free version comes with limited support and sometimes you need to write your own code just to fix Ext JS release bugs. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? UI Development - We provide a feature rich and highly responsive UI to our users and availability of interactive UI components is a must. The Ext JS components like grids and panels make that job easier and provide users with a fabulous UX experience. Review collected by and hosted on G2.com.

Marketing Executive Small-Business (50 or fewer emp.) 7/20/2020 "Varied languages ​​and extensive tools." 4/5 What do you like best about Ext JS? A larger html ecosystem used in the design area for me has been phenomenal and I have used this service and in general the use of html, api or Java codes and different languages ​​makes Ext Js stand out, I like it because the tools are not just one language but it allows me to express different types of language and get to the application that I want to run is for this reason that I like the system because it has provided solutions for what I need, be it designing a page, improving our telephone application or simply improving a system of sales. the code system for us has been fundamental and Ext JS has worked to be able to do it. Review collected by and hosted on G2.com. What do you dislike about Ext JS? There may be criticisms such as not knowing how to use the system, although for me it is simple for those who do not have prior knowledge of languages, it can be complicated, however it can be difficult for them to understand the systems and codes such as: Java, api is for this reason that although it is not a negative point it can fail the system affects users who want to try it, they can get lost in their tools. Review collected by and hosted on G2.com. Recommendations to others considering Ext JS: I definitely recommend it because the result we have is favorable, we do not have any type of problem in this regard because we understand how this type of language works, that is why I recommend the service because it works. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? To design a page or an application, the advertisements or the realization of a program for sales, codes are needed, investigating we found this Ext JS software and we implemented it in order that it only maintained a single language, but it was not the Ext JS tool. It is very broad so it was extremely comfortable for us to work on our own language in this way we can design and do everything we want without any problem and total freedom.

SS Sandy S. Private Wealth Management Assistant Enterprise (\> 1000 emp.) 2/25/2020 "Great quick-development framework." 4/5 What do you like best about Ext JS? 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. Review collected by and hosted on G2.com. What do you dislike about Ext JS? 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. Recommendations to others considering Ext JS: This is not like several others an open source structure, but you have a great deal of value for what you're paying for. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? This assisted us in creatin user interfaces that are robust and reliable. I am using it primarily to create administration analytics and make it user-friendly without worried about other challenging-to-use web structures or prebuilt templates.

KJ Kumar Sheetal J. Research Analyst Small-Business (50 or fewer emp.) 1/25/2020 "My experience with Ext JS" 4/5 What do you like best about Ext JS? 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. What do you dislike about Ext JS? 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. Recommendations to others considering Ext JS: Well there are various reasons why one should opt for Ext JS. Apart from pricing , I feel It is one of the best available in the market. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? I used this for my college project. I have created single-web-page application using Ext JS.

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. What do you dislike about Ext JS? 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. Recommendations to others considering Ext JS: Extjs is not like working with react or angular, But it is a complete toolkit/framework witrh a lot of components and a good roadmap + support Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? We have a working one-page-app with some pretty advanced functionality that works in all browsers. Working with model-view-controller is so great and just anyone can jump into the code and imediately understand whats going on, if they have som extjs knowledge.

AP Andy P. Web developer Small-Business (50 or fewer emp.) 1/22/2020 "Fantastic framework for rapid development" 4/5 What do you like best about Ext JS? 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. Review collected by and hosted on G2.com. What do you dislike about Ext JS? 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. What problems is Ext JS solving and how is that benefiting you? It helped me build complex and consistent user interfaces. I primarily use it to build administrative dashboards, to make it friendly for customers to use without having to worry about other web frameworks difficult to use, prebuilt templates and HTML markup.

Mid-Market (51-1000 emp.) 1/21/2020 "My Journey Experience from ExtJS3 to ExtJS6" 4/5 What do you like best about Ext JS? Powerfull components and integration with other third party lib's Review collected by and hosted on G2.com. What do you dislike about Ext JS? Few of the components are challenging to learn and use Review collected by and hosted on G2.com. Recommendations to others considering Ext JS: Try it you will love it. I would recommend using ExtJS, it has flexibility to integrate with other libraries making it more powerful. Documentation and support are top-notch. Easy to integrate with any server-side framework. Support of multiple browsers Support of Mobile devices. MVC and MVVM framework Can easily debug the js library. Dislikes: Cost Difficult to use themes HTML editor component needs enhancements, it looks like a very basic version. Graphs are not clear, they look dull. Id and ItemId made automation testing difficult, we need to build our own id attribute for automation. Pivot grid performance issues. Focus issues, on a few systems Suggestions: Provide more default themes. Need a theme with smaller fonts, icons, tabs etc..similar to classic theme. HTML editor with more options. Inline filters on the grid. Editable Grid - Direct Component to support all features similar to MSExcel. Internationalization If you are and UI developer, I would recommend to ty ExtJS, if you are still looking for other frameworks you can still go with ExtJS as you can integrate with other libraries too. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? We had built an awful UI for our enterprise application. A lot of inbuilt component which are ready to use and integration with other libraries. A lot of time-saving by using the readily available components and easily pluggable. Support of web and mobile with the same libraries. Review collected by and hosted on G2.com.

Team Lead & Product Manager Mid-Market (51-1000 emp.) 1/16/2020 "If you want to create a business application, you should go with ExtJS" 4/5 What do you like best about Ext JS? The fact that ExtJS has ready components Review collected by and hosted on G2.com. What do you dislike about Ext JS? Learning curve that ExtJS has was quite a big. Review collected by and hosted on G2.com. Recommendations to others considering Ext JS: Remember that learning curve is bigger than with other frameworks, but when you/your team make it, you will have a powerful JS framework on your hands to create great business applications. However if you are going to make nice sexy interface for a game or so (not business application), maybe other frameworks will suite your needs better. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? We use ExtJS to create a business application that looks like a business application. Benefits of the ExtJS are that it includes ready components for business application. For example if you create Payroll, Finance, Material Handling, Warehousing, Sales (=ERP), OM, CRM etc. application, ExtJS is the right JS framework for that. It is not as sexy or hip as ReactJS or the learning curve is not as easy as Angular has - but for business applications it has the right components and you don't need to use time developing them or the functionality to those components. If you have for example 10 developers, you decide what components you will have and how your application should look like - you don't need to create boiler plate or some other kind of UI + component development hazzledazzle like you would need to do with many other JS frameworks.
