I replaced JasperReports with JavaScript – and it's 4 faster

说明与用途

ReportWright 用 JavaScript 替代 JasperReports，报告生成速度提升 4–5 倍，并支持 PDF、Excel、Word、PowerPoint 以及交互式 HTML。

问题

JasperReports, SSRS, and Crystal Reports require JVM/.NET and paid servers, and do not fit a JavaScript stack.

结果

ReportWright is 4–5× faster than JasperReports for grouped reports, 2× faster than QuestPDF for single invoices, and streams a million rows in 53 s with flat memory.

工作流

• Install ReportWright packages via npm
• Define report schema in JSON
• Provide data sources and datasets
• Render report with render()
• Export PDF with exportPdf()
• Write output to file

证据

I benchmarked it on GitHub Actions (4 vCPU) against other engines, checking every output file.
