Grate grids/views, combo, tag fields that works together with grid editors, same look and feel for all components (buttons inside toolbars, outside...). Nice theming mechanism and you can do your one theme and even use it in kitchensink examples to showcase all components with your theme (few tweaks required). Easy to create new components by fist using internal ones and orchestrating them. Add custom ui's to create different style of the same component. When you understand the concepts and how it works, you don't need support or google help, this is why "posts count" does not always matters. Review collected by and hosted on G2.com. What do you dislike about Ext JS? Build tool is custom, not allowing latest JS standards (all). custom imports... but not a big problem when you understand reasons and how it works. ext-reactor discontinued and ext-react does not yet support typescript types so good. In some cases troubleshooting of missing required files on a build app is hard and you don't know what require (class name) is missing. Review collected by and hosted on G2.com. Recommendations to others considering Ext JS: Look at docs and examples (lot of them), always use them as first "helping" point, then search on sencha forum then on google :) Review collected by and hosted on G2.com.

Small-Business (50 or fewer emp.) 1/15/2020 "Great for building UI quick and easily." 4.5/5 What do you like best about 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.

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. What do you dislike about Ext JS? 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. Recommendations to others considering Ext JS: Consider strongly whether to use the full framework or just the widgets with another framework. Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? The consistent look and feel and quality of the widgets is outstanding. This allowed us to build our primary Staff facing UI for our enterprise product such that it works cross browser, cross platform, and provides a very professional and consistent look and experience for our users. Layout is adaptive based on meta-data, and it looks consistent and clean throughout. Review collected by and hosted on G2.com.

"Ext-JS the best javascript library for business application" 4.5/5 What do you like best about Ext JS? 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. What do you dislike about Ext JS? 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. Recommendations to others considering Ext JS: Don't ask for free javascript components and libraries, ask for a unique and better suite of hundreds components . Review collected by and hosted on G2.com. What problems is Ext JS solving and how is that benefiting you? With ExtJS + Kitto we build Web application in a very fast way: the applications are very robust and we continue to work on Kitto to support new features that ExtJS 7 introduced.

SG Samuel G. COO, Co-Founder Small-Business (50 or fewer emp.) 1/15/2020 "Powerful tool for UI development" 5/5 What do you like best about Ext JS? 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. What do you dislike about Ext JS? 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. Recommendations to others considering Ext JS: We recommend others to use Ext JS for their web development. It is maybe pricey compared to other tools such as react and angular. However it is one of the only licence you need for your UI development and it is definitly worth it. Review collected by and hosted on G2.com.

Everything is centralized in Ext Js which allows us to move quickly in our development. Review collected by and hosted on G2.com.
