WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
This is related to some issue with Safari's new WebGL 2 implementation they shipped recently[1]. Currently we disable the webgl renderer on Safari inside github.dev/codespaces to work around this.

term.js was originally created by Fabrice Bellard -- see the headers of @chjj's term.js file [1]. Bellard wrote term.js since he needed a way to interact with his amazing port [2] of Linux to a web browser. Term.js had a non-open-source license and @chjj spent time a decade ago successfully convincing Bellard to relicense term.js open source (I watched and greatly appreciated this as it happened!). Xterm.js is a very significant rewrite and improvement of term.js, mostly done by Daniel Imms who is on the VS Code team at Microsoft; xterm.js is a great contribution of Microsoft to open source, and is used at VS Code's terminal. I watched all this happen over the years, visited Daniel at Microsoft, etc.; I think this is all very useful tech (e.g., we use it in JupyterLab and CoCalc).

Fun fact - xterm.js was originally created by chjj who also wrote the code for Handshake DNS among other things.
My favorite is blessed [1].
He’s definitely a super programmer. Thank you for all your contributions to this world @chjj!

You can check out the source for the demo at https://github.com/xtermjs/xtermjs.org/blob/master/js/demo.j..., I've actually started hacking up a more general mechanism for doing this since I've done it a few times but it's not OSS yet.
If you don't need to rely on ccrypt and just want to emulate teh experience of using it, you could have an on rails experience by forking the demo file and adapting the commands part.
I just want to say thanks, I have been experimenting with using xterm.js to connect to terminal API in jupyter notebooks and it was worked really well, plug and play (even editors like vim were working without any extra effort).
Before that I was experimenting with using it as a custom shell for running commands inside a web application. In that use case it was a bit more challenging because I had never written to an actual tty before (ansi escape codes for coloring log files has been about the limit of my experience). For that use case I just really needed to send and receive text. I ended up using this library [ https://github.com/wavesoft/local-echo ] to smooth that process out until I could learn about how to do things properly.
Are any suggestions on 1. where to learn about how ttys work to things the right way, or 2. suggested libraries like local-echo that can wrap over some of the trickier bits of just getting text on the screen?
Thanks again for maintaining such a great & useful library!
