Building a better online editor for TypeScript (blog.val.town)

Why not Monaco? It works great.

I've done something similar for the Mint, and it's try page: https://mint-lang.com/sandbox/try (and all interactive snippets).

The client (CodeMirror) connects to the language server though WebSocket to offer semantic highlighting and some custom LSP actions related to compiling and serving the project.

Shoots themselves nicely in the foot for scaling and profitability to have to centralize all the work for everyone forever

I worked on adding a web-vscode editor in my project (MCP gateway https://mcp-boss.com). Initially i also spun up a container to provide terminal access, package installation etc. It turned out to be very resource intensive, and the cold-start-up UX sucked. This approach also comes with scaling challenges.

Leaning on CloudFlare Containers seems like a good balance though. But im wondering what the limits are, some packages are very large and require more than just Javascript (e.g node gyp).

(Personally I ended up hosting a web-only VS code served as static files. Luckily i dont need to support Deno syntax so the built-in Typescript language server worked fine.)
