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>();

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

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",
  },
}
