However, with the introduction of ShellRoute, observing the navigation flow in your app and having routes that are "aware" of navigation changes has become more difficult. As highlighted in this issue, when you add a ShellRoute, the app loses reactivity to route changes: the NavigationObserver is no longer triggered.

Project mention: Linkwarden: FOSS self-hostable bookmarking with AI-tagging and page archival | news.ycombinator.com | 2025-05-01
for PDFs I thought about using https://github.com/phiresky/ripgrep-all or pdfgrep https://pdfgrep.org/
For images, what do you want to grep for? for exif data -> https://exiftool.org/ if you want to find image based content, you might need something smarter. I think maybe it is a place where tools such as https://github.com/ultralytics/yolov5 can shine for me. simple enough to work with most of my images and tag them according to some preferences, and I would save such tags in a txt file.
Anyway, all metadata I store about images, links etc are all persisted in txt files. summaries, tags, etc, incoming/outgoing links etc, each has its own file. There are folders per link/content. Under each folder, one file per type of metadata. So it is very easy to know if some metadata is missing for a file, no index needed, it is just as simple as checking the presence of a file.

Avalonia
Develop Desktop, Embedded, Mobile and WebAssembly apps with C# and XAML. The most popular .NET UI client technology
Check out https://avaloniaui.net as well. It's basically a cross-platform reimplementation of WPF. It's not quite as simple as C#+WinForms or Lazarus+LCL because you don't get drag-and-drop UI designer, and you need to write markup by hand (albeit with live preview). But unlike HTML, it's actually designed for desktop UI apps from the get go, so it's much easier to write for anything non-trivial. And you can still write "quick and dirty" GUI code by directly connecting event handlers to buttons and updating values etc in it, ignoring data bindings and other more advanced facilities.

I have a bit of an obsession with finding the fastest way to launch apps. My goal is to be able to create fully functional MVP's and proofs of concept in less than a day. That means being able to spin up a backend and then implement a frontend as efficiently as possible. For the backend, PocketBase has been my favorite lately. On the frontend I am still trying to find a winner. I like Quasar (VueJS + Capacitor) which is fantastic for web apps, but falls a bit short for mobile apps. I've been eyeing React Native lately especially since Expo offers a ton of great plugins like Location and also supports remote updates.
