What to Know About Deno 2.0

on YouTube ↗26m

" summary

Deno 2.0 lands as a Rust runtime (Tokio + Hyper, embeds V8) with secure-by-default permissions, built-in TypeScript tooling, a key-value store and global hosting on Deno Deploy across ~30 data centers using V8 isolates. HTTP imports stay supported but a new centralized registry (deno.land registry / deno.json metadata) enforces semver, licenses and TypeScript checks; a publish CLI and DNT tool produce Node-compatible packages. The aim is consistent local-to-deploy behavior.
