What it does

OPFS Explorer solves a common pain point for modern web developers: the Origin Private File System (OPFS) is invisible by default. Browsers do not provide a native way to inspect files stored via `navigator.storage.getDirectory()`, making it incredibly difficult to debug applications using SQLite Wasm, File System Access API, or offline PWA storage.

Inspect, manage, and edit files in the Origin Private File System directly from Chrome DevTools. - hasanbayatme/opfs-explorer

  • Use-Fs – A React Hook for the File System Access API and OPFSAug 2026 · use-fs.com · ▲5

    I'm happy to say that https://use-fs.com 2.0 has been released with brand new OPFS support. If you're building browser-based apps that heavily interact with the file-system this package is a must to have in your package.json! A React hook that watches a directory and re-renders when a file is added, changed, or deleted. Point it at a folder the user picked and you're reading and writing their real files — no uploads, no endless file dialogs New in 2.0: it watches the origin private file system too. No picker, no permission prompt, no user gesture — and, unlike File System API, it…

  • Inspect and extract files from MSI installers directly in your browser2025 · pymsi.readthedocs.io · ▲135

    Hey everyone! I'm excited to share a small web app I built that allows you to view and extract the contents of Windows MSI installers directly in your browser. It's essentially a web-based "lessmsi" powered by Pyodide. You can try it out at: https://pymsi.readthedocs.io/en/latest/msi_viewer.html My motivation for building this was from part of my day job -- I often get Windows MSI installers and need to extract files while preserving the relative directory structure and filenames, as they would appear after a full installation. The existing tools I found were good…

  • Simple org-mode web adapterFeb 2026 · github.com · ▲63

    I like to use org files a lot, but I wanted some way to browse and edit them on my phone when I'm out. Yesterday I used Codex to make this simple one-file web server that just displays all my org files with backlinks. It doesn't have any authentication because I only run it on my wireguard VPN. I've been having fun with it, hopefully it's useful to someone else!

  • Talanoa▲346

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
