Use when scaffolding a new pdf-lib project or adding pdf-lib to an existing project. Prevents incomplete setup: ensures TypeScript config, fontkit registration, and correct imports are all in place from the start. Covers Node.js and browser variants,…
Use when reviewing or validating pdf-lib code before deployment. Prevents shipping broken PDF generation: runs a 7-point checklist covering async/await, coordinate system, font handling, imports, form handling, and known anti-patterns. Catches issues Claude's…
Use when starting a new pdf-lib project, setting up imports, or understanding the library architecture. Prevents the #1 AI mistake: forgetting async/await on pdf-lib operations and using top-left coordinates instead of bottom-left. Covers PDFDocument…
Use when debugging unexpected pdf-lib behavior — blank pages, wrong positions, missing content, or runtime errors. Prevents the top 10 pdf-lib mistakes: forgotten await, wrong coordinate origin, unsupported image formats, cross-document page errors,…
Use when encountering font errors in pdf-lib — WinAnsi encoding failures, fontkit registration errors, or unicode characters not rendering. Prevents repeated debugging: standard fonts ONLY support Latin-1 (WinAnsi). Any non-Latin text requires custom fonts…
Use when PDFDocument.load() fails with encryption errors, malformed PDF errors, or unexpected parsing failures. Prevents silent data loss: pdf-lib cannot decrypt PDFs — ignoreEncryption only skips the check, it does not decrypt content. Covers encrypted PDF…
Use when filling existing PDF forms or creating form-filling workflows with pdf-lib. Prevents the #1 form mistake: not calling form.updateFieldAppearances() with a custom font before flattening, causing unicode text to disappear. Covers form loading, field…
Use when merging, splitting, or reordering PDF pages across documents with pdf-lib. Prevents the critical cross-document error: directly adding pages from another document instead of using copyPages() first, which corrupts the PDF. Covers copyPages workflow,…
Use when positioning content on PDF pages — margins, centering, columns, or content flow across pages. Prevents the #1 layout mistake: using top-left coordinates instead of pdf-lib's bottom-left origin. Provides a top-down positioning helper pattern (height -…
Use when building complete PDF documents from scratch with pdf-lib — invoices, reports, certificates, or multi-page layouts. Prevents content overflow by providing page-break detection and content flow patterns. Covers multi-page generation, headers/footers,…
Use when creating, loading, or saving PDFs with pdf-lib, or setting PDF metadata. Prevents common mistakes: missing load options for encrypted PDFs, forgetting saveAsBase64 for browser contexts, and metadata not persisting due to wrong setter order. Covers…
Use when drawing shapes, lines, or SVG paths on PDF pages with pdf-lib. Prevents the common color value mistake: pdf-lib uses 0-1 range for rgb/cmyk, not 0-255. Covers drawRectangle, drawCircle, drawLine, drawSvgPath, color constructors (rgb, cmyk,…
Use when embedding fonts in pdf-lib or handling non-ASCII text in PDFs. Prevents the #1 font error: using standard fonts for unicode text, which throws WinAnsi encoding errors. Standard fonts only support Latin-1 characters. Covers StandardFonts, custom…
Use when working with PDF form fields in pdf-lib — reading, creating, or manipulating fields. Prevents the common mistake of not calling form.flatten() after filling, leaving forms editable when they should be locked. Covers getForm, all field types (text,…
Use when embedding or drawing images in pdf-lib PDFs. Prevents the common mistake of using unsupported image formats (only PNG and JPG are supported — no SVG, GIF, or WebP). Covers embedPng, embedJpg, drawImage, image scaling, aspect ratio preservation.…
Use when adding, removing, or manipulating pages in a pdf-lib document. Prevents incorrect page sizing by providing the complete PageSizes enum (55 sizes) and correct dimension methods. Covers addPage, insertPage, removePage, getPage, page dimensions,…
Use when drawing text on PDF pages with pdf-lib, including positioning, multiline text, and text measurement. Prevents the common mistake of using top-left coordinates for text positioning (pdf-lib uses bottom-left origin). Covers drawText options, text…
