Got distracted while swapping out monaco for codemirror on the note node

it's only a tiny tweak to codemirror to have it wrap each change with a view transition 😅

I upgrade an entire project from .NET 8 to .NET 9, it just works. No hassle. Just... done.

I try to run a nodeJS build that worked YESTERDAY, with no changes, and it fails because the nodeJS ecosystem is about as stable as a tectonically active goth on rollerskates after a litre of supermarket gin.

Managed to get typescript types resolving in a Codemirror editor based on X-Typescript-Types headers from @esm.sh using @val.town's codemirror-ts extension with a bit of help from Claude to glue things together. Gotta love standing on the shoulders of giants.

It's okay ChatGPT, I feel the same way when I start poking around ProseMirror / CodeMirror decorations...

this summer @val.town had an intern, and he was truly kickass: read about how @404wolf.bsky.social put the @deno.land LSP server in a cloudflare container, made it speak websockets, wired it up to codemirror, and made the whole thing scale: blog.val.town/vtlsp

building a code editor in the browser is hard

huge kudos to @404wolf.bsky.social for making ours so good

this work is open-source, so you too can have amazing autocomplete, type information, go-to-definition, in your codemirror editor

CodeMirror is just as hyperextensible as nvim actually
September 11, 2025 at 9:00 AM
codemirror is good yea
October 6, 2025 at 11:58 PM
given how fast the web changes i'm honestly shocked at the things that stay the same. like, we're still using CodeMirror for code editors??

New video 🎬 How to build a self-typing editor demo with Waku + CodeMirror #devaslife

implemented twoslash support in codemirror-ts - a neat pattern invented by @orta.io (afaik) to show type information by writing a special-looking comment, and then your editor shows info as ghost text github.com/val-town/cod...

I got out in the deep end of rendering MyST previews in real time with codemirror in a browser and it's been a tremendous learning experience.
