BUILDING A BETTER ONLINE EDITOR FOR TYPESCRIPT

Summary from the TLDR Web Dev newsletter

Val Town has rewritten and open-sourced its online TypeScript editor from scratch to improve its performance and accuracy. The previous editor ran TypeScript in a Web Worker, which struggled with Deno-specific features and large NPM modules. The new editor uses the official Deno Language Server, running it remotely in cloud containers managed by Cloudflare, resulting in a faster, more reliable experience.
