7월 3, 2024
가장 복잡한 데이터를 처리하는 도중에도 스프레드시트 성능을 유지하는 데 도움이 되는 증분 계산이 SpreadJS 17.1.0에 도입되었습니다.

SpreadJS by MESCIUS is a JavaScript library offering a comprehensive spreadsheet solution for enterprise web applications. It delivers an Excel-like user experience with features like data tables, extensive charting, formatting options, and a powerful formula engine supporting over 500 functions. SpreadJS integrates with popular frameworks like React, Angular, and Vue.js, enabling developers to build high-performance, customizable spreadsheet functionalities within their web applications.

The SpreadJS v17.1 release enables incremental computation, which breaks down the entire calculation into pieces during execution. This enables responsiveness to user actions when the calculation task is large, preventing the UI from being unresponsive when a workbook has many formulas. Developers will only need to set the incrementalCalculation attribute of the Workbook class to true. This computation procedure is also displayed in the status bar.

To see a full list of what's new in 17.1.0, see our release notes.

SpreadJS is licensed per developer and includes 1 Year Maintenance (major and minor version releases and unlimited support phone calls). SpreadJS requires an Annual or Perpetual Deployment License. The optional Add-ons are available at an additional cost, and require a SpreadJS license. See our SpreadJS licensing page for full details.
