New Features and Components of Ext JS 8.0
Official Website: https://jp.sencha.com/
Sencha is adopted by 60% of Fortune 100 companies, with a track record of adoption at companies such as Morgan Stanley, Hitachi Energy, Blue Yonder, Citigroup, Motorola Solutions, and the BMW Group. The Sencha Ext JS framework automatically optimizes display for browser environments, reducing development effort required to adapt to differences in operating systems, browsers, and devices like desktops, tablets, and smartphones. It also features over 140 feature-rich components, comprehensively supporting the entire cycle of web application development, including UI visual design, development, theming, and testing, enabling seamless design, development, and testing of feature-rich cross-platform web applications.
This release introduces numerous new components required for modern application development. Features include the "Responsive Digital Signature Pad" that allows capturing signatures directly within the application, and the "QR Code Reader & Generator" that supports diverse business workflows such as payments, logistics, and retail. Furthermore, significant improvements have been made to enhance the quality and productivity of the development environment, such as drastically speeding up grid rendering with horizontal buffering that supports large datasets of over 1,000 columns.
Notably, this version maintains complete backward compatibility, meaning existing applications do not need to be rewritten. Key new features and updates are detailed below:
■ Responsive Digital Signature Pad (Classic & Modern toolkits)
This new add-on component, requiring no third-party libraries, allows for direct electronic signature acquisition within the application. It is built by extending native Ext JS components and integrates seamlessly with Grid, Form, and Panel containers. It offers a rich feature set including Undo/Redo, Clear, pen width/size settings, background color selection, and a color picker, and supports signature export in multiple formats like JPG, PNG, and SVG. It is applicable in a wide range of business applications such as approval workflows, onboarding forms, compliance signatures, and field services.
■ QR Code Reader & Generator (Classic & Modern toolkits)
A new component for generating and reading QR codes has been introduced. It supports diverse data formats such as URLs, text, VCARD/MeCard, calendar events, location information, phone/SMS, email, Wi-Fi settings, and payment data, and supports drawing in SVG, Canvas, and PNG formats. It enables QR code workflows to be completed within the application without external dependencies, for purposes like payment confirmation, asset tracking, contact sharing, and Wi-Fi provisioning. It also supports custom colors, flexible size control, responsive UI for desktop and mobile, and input sanitization for security.
■ Grid Rendering Speed-up with Horizontal Buffering (Modern toolkit)
The grid in the Modern toolkit now features rendering optimization through column virtualization. By drawing only the visible cells and a configurable buffer zone, it enables high-speed display of large datasets exceeding 1,000 columns without performance degradation. This buffering seamlessly integrates with row/column locking, grouping, filtering, editing, accessibility features, RTL support, and all themes.
■ Lockable Grid Plugin (Modern toolkit)
A new Lockable Grid Plugin has been introduced for the Modern toolkit, providing native column lock and unlock functionality. It ensures full compatibility with various grid features, including synchronized horizontal and vertical scrolling between locked and normal areas, selection models, cell editing, and summaries.
