Introducing a New Go PDF Library: Fast, Lightweight, and CJK-Friendly Solution for PDF Generation

Introduction: The Need for a Modern Go PDF Library The landscape of PDF generation libraries in Go is fraught with compromises. Developers face a stark choice: archived projects like gofpdf , which lack active maintenance and updates, or overly complex solutions that rely on external dependencies such as Chromium. The latter, while functional, introduces significant bloat —binaries can swell to 300MB—and performance penalties due to slow cold starts. This is a direct consequence of their architecture, which prioritizes feature completeness over efficiency and simplicity. Maroto , another contender, falls short with its limited layout capabilities , making it unsuitable for complex document structures. These limitations are not merely inconveniences; they are barriers to productivity , forcing developers to choose between functionality and performance. The root of these issues lies in the system mechanisms of existing libraries. Many rely on intermediate representations or external tool
