There’s lots to love (like usual) with the latest release of Deno, the super slick Typescript, JavaScript, and Web Assembly runtime!

If you don’t know me, you wouldn’t know this — I’m obsessed with Deno. So naturally I am going to write about it every chance I get. I’m a few days behind the release, but I was busy with the Hackmamba Jamstack Hackathon this week (content coming on that as well). So without further delay, let’s get to the latest release of Deno!

Deno 1.27 — Better than 1.26.2….

I’ll just start by going down the list:

  • Language Server and Integrated Development Experience improvements

So the first big one here is actually what got me super excited to write about this release — Deno exposes the inlay hints functionality that TypeScript added in version 4.4. I absolutely love the inlay hints as I have been using them for a while now with JetBrains products and they are now available in VS Code as well!

There were also improvements to registry completions in Deno (always fantastic) and several bugs were fixed, as usual.

  • Improvements to npm compatibility

This is also big as it helps extend out Deno so much more considering there are so many npm packages…
