Pre-Integrated and Tested UI Components
Ext JS Pre-Integrated and Tested UI Components

Ext JS includes the industry’s most comprehensive collection of pre-integrated and tested high-performance UI components. These components include HTML5 calendar, grids, pivot grid, D3 adapter, trees, lists, forms, menus, toolbars, panels, windows, and much more. Hundreds of user extensions are also available from the Sencha community.

The Sencha Grid enables organizations to handle millions of records and provides out-of-the-box functionality such as sorting, grouping, column locking, and summary rows.

The Ext JS Calendar component helps you easily view/manage schedules and events within your Ext JS apps. By leveraging this component, you can easily add a fully-functional calendar to your apps without investing a lot of time and effort in building one.

Rich Data Analytics
Ext JS enables organizations to add powerful analytics capabilities to their web applications with Sencha Pivot Grid. It allows users to summarize, aggregate and analyze multidimensional data to make more informed decisions.

The Sencha Grid enables organizations to handle millions of records and provides out- of- the- box functionality such as sorting, grouping, column locking, and summary rows.

The Exporter plugin enables you to export your Ext JS Grid and Pivot Grid data in a variety of different formats. It supports the standard XLSX, XML, CSV, TSV, and HTML formats, and allows you to configure the visible (displayed) or invisible (hidden) portions of your data exports. The Exporter plugin also supports basic styling of the exported documents.

Sophisticated Data Visualization
The D3 Adapter enables you to add sophisticated Data-Driven Documents package (D3) visualizations such as heatmaps, treemaps, sunbursts, and more to your web applications. Now you can create dynamic visualizations that not only tell a specific story, but also help your users to explore their data and understand what stories it has to tell.

The Ext JS Charting package allows you to visually represent data with a broad range of dynamic and static charts — including line, bar, and pie charts. The charts use surfaces and sprites developed with a drawing package implemented using SVG, VML, and Canvas technologies. Browser variations are handled automatically, so the charts always display correctly. Ext JS Charts also support touch gestures on mobile devices, thereby providing enhanced interactive features to the charts such as pan, zoom, and pinch.

Back-end Agnostic Data Package
The robust data package included in Ext JS decouples the UI components from the data layer. The data package allows client-side collections of data using highly functional models that offer features such as sorting and filtering. The data package is protocol agnostic, and can consume data from any back-end source. It comes with session management capabilities that allow several client-side operations, minimizing round-trips to the server.

Layout Manager and Responsive Configs
Ext JS includes a flexible layout manager to help organize the display of data and content across multiple browsers, devices, and screen sizes. It helps you to control the display of components, even for the most complex user interfaces. Ext JS also provides a responsive config system that allows application components to adapt to specific device orientation (landscape or portrait) or available browser window size.

Accessibility Package (ARIA) for Section 508 compliance
The Ext JS ARIA Package makes it possible to add accessibility support to your applications by providing tools that you need to achieve Section 508 Compliance. Using the ARIA package, you can create apps that can be used by people who need assistive technologies such as screen readers to navigate the web.

Customizable Built-In Themes
Ext JS components are available in multiple built-in themes including Material, Triton, Classic, Neptune, and Crisp. The themes are customizable to reflect a specific brand identity. Sencha Cmd exposes hundreds of variables used by Ext JS themes, which can be altered to design custom themes.
