Visual Studio Code Deno extension

Adds Deno support for the Visual Studio Code.

Features:

Full intellisense support

Intelligent module import

IntelliSense for remote URL imports

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

Compiler hint

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

see example

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

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

Download and enable the extension from the Visual Studio Marketplace
Enable Deno for your project:

Create a file .vscode/settings.json in your project folder:
```
// .vscode/settings.json
{
  "deno.enable": true,
}
```
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
deno.import_intellisense_origins - The list of origins that import IntelliSense is enabled or disabled for. Defaults to none. More info in the import IntelliSense readme
deno.import_intellisense_autodiscovery - If the extension should try to auto-discover new origins with import IntelliSense support and list prompt the user. Default is true. More info in the import IntelliSense readme

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,
  "deno.import_intellisense_origins": {
    "https://deno.land": true,
  },
}

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,
}
