  • react-pdf

    📄 Create PDF files using React

  • Project mention: How we improved our client-side PDF generation by 5x | dev.to | 2024-03-17

    Using react-pdf, we crafted a solution that allowed users to manipulate their reports with an impressive degree of flexibility. But, as data grew (imagine trying to cram an entire financial year's worth of invoices, up to 22,000 rows, into one PDF), our solution began to falter, especially on older PCs with limited resources.

  • Project mention: Rnote – An open-source vector-based drawing app | news.ycombinator.com | 2024-03-11

    I highly recommend Rnote to anyone on Linux that misses the "hodgepodge" notetaking of apps like OneNote. It works like a dream on touchscreens and drawing tablets, with a surprising amount of configuration under the hood.

    Also worth noting is Xournal, an older but similar project: https://xournalpp.github.io/

  • Dompdf

    HTML to PDF converter for PHP

  • Project mention: Intro to DOMPDF - lightest and simplest PHP library to generate PDF documents | dev.to | 2024-04-05

    Generating PDF documents out of your app's HTML output is a very common requirement and there are several open source libraries to accomplish this. I came across this need for my project recently and I evaluated many popular ones such as TCPDF, mpdf, FPDF, etc. But the one that truly stood up to my evaluation in terms of efficiency (minimal footprint) and ease of implementation was DOMPDF.

  • Zettlr

    Your One-Stop Publication Workbench

  • Project mention: Obsidian 1.5 Desktop (Public) | news.ycombinator.com | 2023-12-26
  • libvips

    A fast image processing library with low memory needs.

  • Project mention: Ask HN: How to handle user file uploads? | news.ycombinator.com | 2024-05-03

    Read through the comments and was surprised no one mentioned libvips - https://github.com/libvips/libvips. At my current small company we were trying to allow image uploads and started with imagemagick but certain images took too long to process and we were looking for faster alternatives. It's a great tool with minimum overhead. For video thumbnails, we use ffmpeg which is really heavy. We off-load video thumbnail generation to a queue. We've had great luck with these tools.
