About DdDesignReport

A reporting library with a drag-and-drop designer, so clients change their own invoice, payslip or report-card layouts.

At a software house every client wants a slightly different invoice, payslip or report-card layout, and every small change such as moving a logo becomes a ticket for a developer. Existing reporting tools are usually tied to one language, like JasperReports to Java, or have no designer that can be embedded in a web app and used by people who do not program.

What it does

• An embeddable drag-and-drop designer. A dependency-free web component (`ddreport-designer` on npm) with a Word-style ribbon, an easy mode for first-time users, hideable buttons and replaceable interface text. Also available as a standalone app.
• One render core for every language. A Go core renders JSON templates to PDF, HTML, XLSX, XLS, CSV, ESC/POS and text. The Node.js and Java/Kotlin wrappers run the same binary, and other languages use the HTTP server or Docker image.
• Complete report elements. Text, tables, images, charts, QR and Code 128, sub-reports, crosstabs, grouping up to six levels, and expressions such as `sum()`, `if()` and `terbilang()`.
• JasperReports export and import. Templates export to `.jrxml` and import back, including charts, lists and crosstabs, so teams already on Jasper can move gradually.
• Ready for production. PDF/A-2b, digitally signed PDFs, a row limit, a health check, a render queue, a strict mode for misspelt fields, and one log line per request.
• Friendly to AI assistants. llms.txt, a JSON Schema, and an MCP server with tools to read the guide, check a template and render it.
