How to use two.js in TypeScript

Question

I am using Visual Studio to write a ASP.NET MVC web application. I am also quite new to TypeScript, but I know C# and JavaScript so I don't have issues with the syntax.

However I am completely confused with importing/referencing .js files, namely for the two.js library:

One of the files (two.module.js) seems to be annotated with JSDoc and ends with:

export default (this || window).Two;

so I am presuming it should be importable as an ES6 module, but how does this work with TypeScript?

I tried using this:

import { Two } from "../twojs/twojs.module.js"

but I get an error (cannot find module "../twojs/twojs.module.js", presumably because it's not a .ts file.

You should be able to import it like this if you installed it into node_modules. The Typescript compiler will resolve the module by finding it in the node_modules folder.

Because it is a default export, you must omit the brackets here.

import Two from "two.js"

Thanks, omitting brackets fixed the problem! I think I'll have to read the TypeScript docs a bit more carefully to get a better idea of how this works.
