The extension separates Client/Server with LSP

This means that complicated problems are handled on the server-side

The extension won’t block your Visual Studio Code

Process

Supports Import Maps for Deno

import_map

External type definitions

The extension supports the following ways to load external declaration files

These are all supported by Deno

  1. Compiler hint
// @deno-types="./foo.d.ts"
import { foo } from "./foo.js";

see example

  1. Triple-slash reference directive
/// <reference types="https://raw.githubusercontent.com/date-fns/date-fns/master/typings.d.ts" />

import { format } from "https://deno.land/x/date_fns/index.js";

format(new Date(), "yyyy/MM/DD");

see example

  1. X-TypeScript-Types custom header
import { array } from "https://cdn.pika.dev/fp-ts";

const M = array.getMonoid<number>();
console.log("concat Array", M.concat([1, 2], [2, 3]));

Usage

  1. Download and enable the extension from the Visual Studio Marketplace

  2. Enable Deno for your project:

    Create a file .vscode/settings.json in your project folder:

    // .vscode/settings.json
{
  "deno.enable": true,
}

  3. Enjoy!

Configuration

  • deno.enable - Enable extension. Default is false

  • deno.import_map - The file paths of Import Map. Default is null

  • deno.unstable - If Deno’s unstable mode is enabled. Default is false

  • deno.lint - If inline deno lint diagnostics are enabled. Because this is experimental, deno.unstable = true is required. Default is false

We recommend that you do not set global configuration. It should be configured in .vscode/settings.json in the project directory:

// .vscode/settings.json
{
  "deno.enable": true,
  "deno.import_map": "./path/to/import_map.json",
  "deno.unstable": false,
}

This extension also provides Deno’s formatting tools, settings are in .vscode/settings.json:

// .vscode/settings.json
{
  "[typescript]": {
    "editor.defaultFormatter": "denoland.vscode-deno",
  },
  "[typescriptreact]": {
    "editor.defaultFormatter": "denoland.vscode-deno",
  },
}

This extension also provides inline deno lint diagnostics. You can enable this in .vscode/settings.json:

NOTE: Since deno lint is still an experimental feature, you need to set deno.unstable = true in your VS Code settings. This function may change in the future.

// .vscode/settings.json
{
  "deno.enable": true,
  "deno.unstable": true,
  "deno.lint": true,
}
