Comprehensive Component Library

Includes a library of 140+ pre-built UI components for application interfaces. The product covers common enterprise requirements with elements such as grids, pivot grids, layouts, charts, calendars, and related interface building blocks for rich client-side applications.

JavaScript Framework for Application Development

The product provides a JavaScript framework for building complex web and mobile applications. It brings framework capabilities and UI components together in a single platform, giving developers a consistent base for large, data-driven application front ends.

Support for Data-Intensive Interfaces

Ext JS is designed for data-intensive applications and includes components suited to presenting and working with large volumes of information. This makes it appropriate for operational screens, dashboards, administrative views, and other interfaces centered on structured business data.

High-Performance Grid Capabilities

The framework includes high-performance grid functionality for displaying and interacting with tabular data. These grid capabilities support applications where users need to browse, inspect, and work with large datasets directly within the interface.

Pivot Grid Summaries

The pivot grid functionality provides rapid summaries of large datasets. This allows developers to build interfaces that organize and present aggregated information in ways that support reporting, analysis, and data exploration inside the application.

Interactive Charts and Visualization

Includes interactive charting and D3 adapters for data visualization. These capabilities let developers add graphical views of application data, from standard charts to more personalized dynamic visualizations, within data-focused web applications.

Responsive Layout Management

Ext JS includes a flexible layout manager for creating responsive web applications. Developers can use these layout capabilities to build interfaces that adapt across modern devices while keeping screens organized and usable as available space changes.

Accessibility Features

The framework includes accessibility support through its ARIA package. The product is presented as aligning with ADA standards and supporting Section 508 compliance, helping teams incorporate accessibility requirements into application interface development.

Decoupled Data Package

Ext JS includes a data package that decouples UI components from the data layer. This supports a more structured application design by separating interface concerns from data handling, which is useful when building complex, data-driven client applications.

Cross-Platform Web and Mobile Development

Designed for cross-platform web and mobile application development on modern devices. It gives development teams a unified framework and component library for building applications that span different device types from a single front-end platform.
