Ext JS includes 115+ pre-integrated and tested high-performance UI components. ## Ext JS Reviews ### 1. A mature framework that provides a complete solution **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** January 15, 2020 **What do you like best about Ext JS?** Ext JS is well documented and most likely if you are looking for a component or functionality, it’s already there. Prototyping new apps is fast, easy and painless. You won’t have to look elsewhere. Some of the biggest media companies, like ESPN are using it. **What do you dislike about Ext JS?** Since 2017, it seems that the framework is in maintenance mode, following the sale to IDERA. Not a lot of new features and we are in 2020. It was close to 3 years between version 6.0 to version 7.00. That’s an eternity in the life of JavaScript frameworks **What problems is Ext JS solving and how is that benefiting you?** Fast and easy prototyping. Solid Grid implementation. Its cost benefits analysis is good. ### 2. Build world-class data intensive web-based applications **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Accounting | Mid-Market (51-1000 emp.) **Reviewed Date:** November 20, 2019 **What do you like best about Ext JS?** Every component you could want. Most of the tedious tasks handled for you. Excellent documentation. **What do you dislike about Ext JS?** This is a tool for data-intensive applications. It is a bit of work to make it look like a typical, information publicly available website. **Recommendations to others considering Ext JS:** Ask yourself if your use is the type of thing Excel could do or would have done historically. If yes, use ExtJS. **What problems is Ext JS solving and how is that benefiting you?** We gather, manipulate, aggregate and present data. This is business. This tooling empowers our business. There are plenty of generic tools out there (BPM, CRM, Calculators, PowerBI,...), but you have unique IP that isn't available, nor do you want it to be. Make it available internally/externally. Turn it into a business tool. Turn it into a profit center. Take all those Excel spreadsheets and turn them into real products that can scale. ### 3. Many years **Rating:** 3.5/5.0 stars **Reviewed by:** Roman K. | Mr, Small-Business (50 or fewer emp.) **Reviewed Date:** July 31, 2019 **What do you like best about Ext JS?** ExtJS is well structured and uses the same syntax and function names regardless of object diffrencess so it makes easier to learn. **What do you dislike about Ext JS?** I don't like many things in ExtJS. From my point of view, model/store model is too complicated and difficult to use. Layouts should be easy to change when needed inside the same container (when I want to change from vbox to tabs for example). Tab panel should be a part of panel definition not a separate type. Instead of making tons of new ExtJS versions like React you should first master the main ExtJS code first. Packages should be unloadable. Definitely you should make web sockets working with ExtJS. **Recommendations to others considering Ext JS:** ExtJS is definitely a good choice if you want to make a web based application, which operates lots of data, also if you want to develop quickly and effortless. You need to keep in mind that it will require constant learning and a lot of patience. Still, it's one of the best frameworks for such purposes available. **What problems is Ext JS solving and how is that benefiting you?** Creating one page applications with tons of data is much easier. Managing huge amounts of data, many requests etc. is much easier. ### 4. Ext JS is awesome, but it's an acquired taste. **Rating:** 4.5/5.0 stars **Reviewed by:** Alexandru B. | Web Developer & Team Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** July 31, 2019 **What do you like best about Ext JS?** Ext JS is very large and resourceful framework and at the same time easily expandable with custom code. The framework documentation is very well structured and vast - when you get the grasp of it the user can easily find anything he needs. I really like the community around Ext JS - there many active users that are usually always happy to help Going into development details, I like the architecture of the framework and how easy it makes for the developer to use it. And by user I mean one with a bit of experience, for first timers it can get a bit overwhelming. Sencha created in the past years different tools to help with the coding that proved to be very useful. I am currently successfully using Sencha Themer, Sencha Inspector and the Visual Studio Code Plugin. **What do you dislike about Ext JS?** 1. There is no (more) support for the community to share custom components. 2. When the community reports a bug, it usually takes a lot of time (if ever) to be fixed. **Recommendations to others considering Ext JS:** Have patience, the learning curve is big but it's worth it. **What problems is Ext JS solving and how is that benefiting you?** Our company's product is huge a SPA (Single Page Application) that involves a lot of data and components. Ext JS solves this gap. ### 5. Have used ExtJS for over a decade; it's the most mature and completele framework out there **Rating:** 5.0/5.0 stars **Reviewed by:** Ivan J. | Software Architect, Computer Software, Mid-Market (51-1000 emp.) **Reviewed Date:** July 30, 2019 **What do you like best about Ext JS?** ExtJS was born out of merit, unlike many of the newer hype-based frameworks owned and proliferated by software giants for purpose of having a technology and developer base that they control. When it comes to building large enterprise grade complex SPA portfolios, nothing scales as well as ExtJS, in terms of scaling vs. complexity, number of products, and number of developers. **What do you dislike about Ext JS?** Since Idera acquisition the delivery on roadmap has been inconsistent and abysmal; the roadmap has changed to a rather reduced subset of the original. **Recommendations to others considering Ext JS:** Consider the modern direction of framework like React, Angular, and View. None offer a set of components, which you either have to obtain from 3rd party or develop yourself (re-invent the wheel). ExtJS has been developing web components for over a decade, and has now made them available for those modern frameworks. **What problems is Ext JS solving and how is that benefiting you?** Our flagship product offering is based on ExtJS and we've been able to leverage our decade of investment in ExtJS codebase for our mobile offerings based on ExtJS modern. ### 6. Helped a lot as a quick prototyping tool for retail enterprise application **Rating:** 4.0/5.0 stars **Reviewed by:** Ananya G. | Assistant Manager, Enterprise (> 1000 emp.) **Reviewed Date:** January 21, 2020 **What do you like best about Ext JS?** Simple widgets, drag and drop panels, easy to understand tutorials for novice. **What do you dislike about Ext JS?** It should have more customization and should be easy to debug. **What problems is Ext JS solving and how is that benefiting you?** Saves a lot of time in making iterations for prototyping. ### 7. Great way of building apps **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.) **Reviewed Date:** January 16, 2020 **What do you like best about Ext JS?** The best features about Extjs is how it draws the User interface automatically and allows me to build various forms , grids easily , also its support for ajax calling allows me to refresh component data without having to refresh whole page **What do you dislike about Ext JS?** The console doesn't show proper errors when components is put in requires part of form or grid , so this may cause me to waste some time till i discover in the end that there is problem with file name **What problems is Ext JS solving and how is that benefiting you?** Extjs helped me create better web applications and improved our user interface to be more modern and user friendly ### 8. Amazing platform to build user-friendly app **Rating:** 4.0/5.0 stars **Reviewed by:** Roman P. | Software Developer, Small-Business (50 or fewer emp.) **Reviewed Date:** January 15, 2020 **What do you like best about Ext JS?** Minimum efforts to create user interface and implement desired behavior. A lot of visual components and flexibility of using them. **What do you dislike about Ext JS?** Sometimes performance causes issues on complex layouts **Recommendations to others considering Ext JS:** Use all benefits **What problems is Ext JS solving and how is that benefiting you?** I avoid to spend a lot of time on working around user interface, presenting data and getting user's feedback. ExtJS helps to stay focused on business logic and product quality. ### 9. Ext JS Senior, 6 years experience started with version 4.2 **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Transportation/Trucking/Railroad | Small-Business (50 or fewer emp.) **Reviewed Date:** January 15, 2020 **What do you like best about Ext JS?** The stable components and power of tables. Build apps in a high performance MVVC concept very fast once you understand the framework. Build apps (PWA) for Android and iOS on one code base. **What do you dislike about Ext JS?** Poor of customizing webcomponents. Long time to understand framework. No community supporting framework out there. **Recommendations to others considering Ext JS:** Depends on your needs. Condsider to have a look on other frameworks because you'll have a hard time to find developers out there knowing Ext JS. **What problems is Ext JS solving and how is that benefiting you?** Processing real time industrial data and visualization. Strong in store and process data fast. Limits in Data visualization often used third party libs inside of ext. ### 10. ExtJS takes reporting to a new level **Rating:** 4.0/5.0 stars **Reviewed by:** John U. | Lead Product Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** August 06, 2019 **What do you like best about Ext JS?** ExtJS makes data tables super easy and gives you a web based excel that users can use to analyze their data. Also the ability to make pivot tables right in the app is an amazing feature. This allows our clients the most flexibility along with being able to save their report templates for later use. **What do you dislike about Ext JS?** Sometimes when there are bugs or pending features, it's hard to get commitment dates from Sencha. There is not m much that we do not like about using Sencha. **Recommendations to others considering Ext JS:** There really is no other solution that is complete as Ext JS...I've looked for other competitors and decided for 2 companies it's the best solution. **What problems is Ext JS solving and how is that benefiting you?** We are solving how to present a large amount of data to clients and allow them to generate ad hoc reporting.

If you are developing a web application, I recommend you buy Sencha, you will not regret it. **What do you dislike about Ext JS?** I don't see an engagement as I do in other development communities, it seems like we are a very restricted tribe. **Recommendations to others considering Ext JS:** You will have a complete application in many aspects, especially graphic quality and performance. **What problems is Ext JS solving and how is that benefiting you?** The main advantages I see are these below: I develop high scale web applications. I deliver solutions in time above the average of other tools of the market. Integrated suite of components, and are very useful and easy to customize components. ### 12.
