Very fast JavaScript and Typescript integration, powered by Deno.

  • Inline Typechecking and Intellisense for Javascript and Typescript!
  • Code linting!
  • Automatic formatting on save!
  • Remote module (e.g. import { x } from "") support!

This is version 0.1. While the most important functions of Deno are integrated here, there are missing features and a few known bugs. This is a best-effort extension, but it might be good enough to start with!

Requirements 🎒

To use this extension, you must have the Deno CLI installed (v.1.10.3 or above). Here's how you can do that.

Commands ⌨️

  • Cache - Cache all external dependencies
  • Format Document - Format with Deno's formatter
  • Rename symbol - Rename variables, functions, etc.

Configuration options ⚙️

  • You can enable/disable automatic formatting on save in the extension preferences.
  • You can de/activate Deno integration on a per-project basis in Project → Project Settings....
  • Support for unstable APIs can also be configured on a per-project basis in Project → Project Settings....

Known bugs 🪳

There are a few bugs which are out of my hands. I'm doing my best to follow up with both Panic and the Deno team to resolve them.

  • Many code actions (e.g. automatic imports) do not work.
  • Autocompletions are only displayed when certain characters are input (., \, ', /, @, <, #).
  • The Jump to definition command does not work for values defined within external dependencies.

Mega Shoutouts 📣

Much of the code in this extension is based on — if not entirely lifted from — Cameron Little's excellent Nova Typescript extension.


This extension is itself a Deno project. Come fix bugs and add features with us!
