Can I code Adobe InDesign?

COPYDon't rebuild InDesign's typesetting engine — for a simple single-page flyer or one-pager, build a minimal page layout tool instead: 1. A fixed-size canvas (a few standard page sizes to start) with text boxes and image placeholders you can position, resize, and layer, using an existing 2D canvas library (Fabric.js or Konva.js). 2. A handful of built-in fonts and basic text formatting (size, weight, alignment). 3. Export to PDF using an existing PDF-generation library (pdf-lib or jsPDF), rendering your canvas layout onto a single page. That's a real, achievable single-page design tool. Out of scope: multi-page layouts with master pages, running headers, and automatic text reflow across pages — real, specialist typesetting engineering — and print-accurate color management (CMYK, bleed, trim marks), a discipline most personal builds never need.
