I'm new to web development and I'm building a local, offline notes app inspired by Discord's layout and visual style. It won't need VoIP, accounts, servers, syncing, or any online features; I mainly want to organize notes, photos, videos, and other files on my own computer.
The front end is currently written with HTML, CSS, and JavaScript. Instead of opening an index.html file in a browser, I'd like to package it as an installable desktop application that launches on its own and works without an internet connection.
Is this practical? What should I learn or use to turn a web-based front end into a standalone desktop app, especially if I need to read and write files on my computer?

A Progressive Web App is probably the simplest place to start. It can be installed from a browser and configured to work offline, so it gives the project an app-like experience while letting you keep using HTML, CSS, and JavaScript. Just keep in mind that it still relies on a browser runtime, and access to arbitrary folders and files can be limited.
You could also use browser File System APIs for some local file operations, especially if a PWA is enough for your needs. However, browser permissions and supported features vary, so a desktop wrapper is usually more reliable when the app needs broad access to local folders.
The least painful path for a beginner is to finish a basic browser version first, then package it. Start by learning how your data will be stored locally—such as files, a browser database, or SQLite—because turning the interface into an executable is only one part of the project. After that, add the desktop wrapper and filesystem features.
Once the front end is working, look at Electron or Tauri. Both can package your existing HTML, CSS, and JavaScript into a desktop application. They also provide a way to work with the local filesystem, which is useful for storing notes and managing photos, videos, and other files.
Tauri is worth considering because it uses the operating system’s built-in webview and usually produces much smaller applications. Electron has more tutorials and examples, but it bundles Chromium and is considerably heavier.
If you want it to feel like a completely independent executable, a web app wrapper would be a better fit than a PWA. A PWA is still essentially using the browser behind the scenes.
