Looking up the Vue.js type definitions in TypeScript

I'm currently working on enabling type checking in my Vue.js code (v2.2.1). My initial goal is to ensure that this specific line compiles with TypeScript (meaning I want the Vue class to be properly identified):

var app = new Vue();

I've discovered that it successfully compiles if I import Vue using:

import * as Vue from 'vue';

However, this approach results in a require() call:

var Vue = require("vue");

Just to clarify, I am not using modules. Instead, I directly reference the Vue library from a CDN before my script.

I attempted referencing the definition file like this:

/// <reference path="../node_modules/vue/types/index.d.ts" />

Unfortunately, the Vue class isn't recognized (most likely because it's exported in the definition file and should ideally be imported?).

Is it possible to use import solely for referencing the type definitions without actually 'requiring' the entire library?

To create a custom definition file (such as vue-global.d.ts), define Vue in the global namespace:

import _vue = require('vue');

declare global{
    const Vue: typeof _vue;
}

Remember to add this definition to tsconfig

If you are utilizing libraries found in the official documentation, make sure to download all necessary files. In your TypeScript file, include the following reference:

/// <reference path="../path_to../app/TypeScript/_definitely_typed/Vue/2.6.10/index.d.ts" />

To make it work, modify the file vue.d.ts.

Firstly, comment out this line:

export const Vue: VueConstructor;

Then add the following piece of code below it:

declare global{
    const Vue: VueConstructor;
}
