Prototype Development of a PDF to Text Extraction and Image Conversion CLI Tool with Node.js and WASM Libraries

I want to extract text and images from PDFs for use in vectorization for RAG. With this background, I developed a prototype CLI tool that's easy to use with Node.js. The key point is leveraging WebAssembly (Wasm) for use in serverless environments. This article introduces the background of our technology selection and an overview of the implementation.

Resolving WASM Module Loading Errors in Next.js v16 Turbopack + Vercel

Are you encountering the unexpected error Cannot find module '.wasm' after adopting Turbopack for a faster development experience with Next.js? The problem becomes even more complex in Vercel environments due to different file structures compared to local development. This article introduces concrete solutions for making WASM modules work reliably with Turbopack and Vercel, using @embedpdf/pdfium as an example.
