Visual Studio Code Deno extension

Adds Deno support for the Visual Studio Code.

Features:

Full intellisense support

Intelligent module import

Supports importing ECMAScript modules

Diagnostics and quick fixes

Optional use of Deno's built in formatting

Client/Server model with LSP

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

Supports `Import Maps` for Deno

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

2. 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

3. 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]));

Deno version manager integration

Investigating integration into the extension

We recommend you using dvm for the manager Deno version.

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

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": "axetroy.vscode-deno",
  },
  "[typescriptreact]": {
    "editor.defaultFormatter": "axetroy.vscode-deno",
  },
}
