BrowserFS VS xterm.js

I think JupyterLite is using localStorage by default. But there are File System APIs for WASM and some external projects[0], I don't think they're yet integrated.

I started my file system with BrowserFS which allowed me to setup IndexedDb as the main writeable location. When in Firefox Private mode it switches to an in memory file system which does not persist. Using BrowserFS also meant I could open ZIP and ISO files as if they were folders. I create a JSON file on build that has the initial public folder directory structure which is used as the readable portion of the file system via plain HTTP GET requests. I've also added the ability to extract RAR files, although I don't currently have it linked to File Explorer to see it's contents before extracting. I can also make and extract ZIP/ISO via fflate.

Thanks for the interest! To do git I used https://isomorphic-git.org/, the terminal is backed by https://xtermjs.org/ and the file system that it writes to is coming from https://github.com/jvilk/BrowserFS. This is all part of my side project (https://github.com/DustinBrett/daedalOS) to build a web desktop environment.

Thanks, I'm glad to hear you liked it! I am using BrowserFS to create writeable data on IndexedDb.

I'm on the VS Code team and maintain xterm.js which is what Hyper's frontend is based on. There are actually multiple developments happening in this area.

First, there's a contribution from the author of DomTerm which adds grapheme cluster support to xterm.js, which will correctly merge and size things like emoji that are called out in the post. This is currently based on Unicode 15. See https://github.com/xtermjs/xterm.js/pull/4519

Second, while Windows Terminal does seem to work with emoji sometimes, it doesn't all the time. I'm not 100% sure, but I think it may only work on Windows ptys, not in WSL for example. Last time I spoke with the team they said they're working on a rewrite which could lead to proper emoji support.

Ooh, I lack the time to play with this, but I think someone could compile the lib to WebAssembly and tie it in to https://xtermjs.org/

Then you could have a web page with static DOM elements that do this effect!

xterm is a JavaScript library that provides a web-based terminal emulator with ANSI escape sequences, Unicode characters, and other features. It is easy to use and customize, making it a popular choice for adding a terminal interface to web applications.

The simpler path would be starting the WASM port using Emacs character mode running alongside an in-browser terminal emulator such as XTerm.js.
