Claude Code uses Bun written in Rust now
Yes, in the Monaco editor (https://microsoft.github.io/monaco-editor/). It's not just typechecking, the typescript library is also the reference parser for TypeScript and reference emit. Emitting TypeScript is non-trivial and non-local. It's not just in browsers, you might want to run the typescript library on the edge or in some restricted environment where JS/WASM is OK but native code is not.

I built a GUI-powered Userscript manager for faster userscript creation!
So I switched to Monaco editor, the same editor that powers VSCode. The extension instantly became a few MB heavier, but it was definitely worth it. Monaco editor was extremely powerful, with all the standard editor features such as renaming variables, syntax highlighting, and more just out of the box. I'm so glad I didn't have to implement any of that myself, yet it's available for everyone to use. - Source: dev.to / 4 months ago
Font with Built-In Syntax Highlighting (2024)
I have yet to see a good web based text editor with syntax highlighting. I slightly expect you to pull a "no true Scotsman" here and suggest it's actually no good because it doesn't really support mobile browsers very well, but Microsoft's Monaco editor that's driven from VS Code is quite good. https://microsoft.github.io/monaco-editor/. - Source: Hacker News / 8 months ago

An experiment in UI density created with Svelte
VS Code Editor which is based on Electron, is really fast, even with large codebase & many open tabs. Their monaco engine (https://microsoft.github.io/monaco-editor/) uses custom, virtual code processor that is optimized for surgically updating underlying DOM. It also uses WebGL + canvas rendering to show minimap of the file. Similar approach (custom virtual processor) is leveraged by Google docs/sheets. Canvas... - Source: Hacker News / about 2 years ago

Your LLM can scrape the web — locally, without writing throwaway code
The key line is the nested URL: {{{FromExp=fromJSON(fRes).author_key[0]}}} is an expr-lang expression evaluated against the current item (fRes) — parse it, take the first author key, splice it into the URL. Anything expr-lang can compute can become part of a request: pick a field, concatenate, add an offset, branch on a condition. And notice the output shape: each book keeps its own scalar fields while the... - Source: dev.to / 18 days ago
