  • DEMO - Voice to PDF - Complete PDF documents with voice commands using the Claude 3 Opus API
    ReadPdf: used for reading the dropped file and displaying it on the screen, it uses PDF.js to load the file, get all fields and display it on the browser. - Source: dev.to / 1 day ago
  • Building W-9 Crafter
    I first started building the app in the browser, using PDF.js and Download.js to take a PDF and edit it, and then download it to your computer. - Source: dev.to / about 1 month ago
  • How to Write a Cold Email
    I'd think opening a PDF in your browser would be at the same risk-level you associate with going to any random URL. On Firefox at least, I'm pretty sure the built-in PDF viewer is simply JS parsing and rendering the PDF anyway -- nothing with elevated permissions: https://mozilla.github.io/pdf.js/. - Source: Hacker News / 6 months ago
  • PDF Chat with Node.js, OpenAI and ModelFusion
    We use Mozilla's PDF.js via the pdfjs-dist NPM module to load pages from a PDF file. The loadPdfPages function reads the PDF file and extracts its content. It returns an array where each object contains the page number and the text of that page. - Source: dev.to / 8 months ago
  • Printing as PDF: Chromium takes ages and 5Mb, while Webkit is super fast and light
    I’ve been using pdf.js before, worked quite well. Source: about 1 year ago
