pdfmake is a PDF document generation library that works in both server-side and client-side JavaScript environments.
The tool addresses the need to generate PDF documents programmatically without relying on external services or native binaries. It works by providing a declarative API where developers define document structure, styling, and content in JavaScript, which the library then renders into PDF format. The library handles layout concerns including text wrapping, alignment, pagination, and complex nested structures automatically.
Developers should choose pdfmake when they need to generate PDFs directly within a JavaScript application without external dependencies. It suits projects ranging from simple report generation to complex documents with tables, headers, footers, and dynamic content. The tool is particularly useful for applications that need to produce PDFs in the browser or on Node.js servers using the same codebase. The library includes features like table of contents generation, font embedding, multi-level nested structures, snaking columns for newspaper-style layouts, and automatic header repetition across page breaks. A playground and examples are available to explore capabilities before committing to adoption.
The project maintains active development with regular updates and a documented build process supporting both npm and yarn. The codebase is written in pure JavaScript with no native dependencies, making it portable across environments. Documentation is maintained in a separate repository with an explicit invitation for community improvements, indicating an openness to external contributions and feedback on the documentation quality.
