Import from installed @types?

Question

I\'ve installed md5 (also tried blueimp-md5) package with corresponding typings like this:

nmp install --save md5 @types/md5

Answer 1

You don't need to specify the path inside the node_modules, it should be:

import * as md5 from "md5";

The compiler will look for the actual module in the node_modules, and will look for the definition files in node_modules/@types.

There's a long doc page about it: Module Resolution

Edit

That's because of how the md5 module is exporting, as it does this:

declare function main(message: string | Buffer): string;
export = main;

This case is covered in the docs:

The export = syntax specifies a single object that is exported from the module. This can be a class, interface, namespace, function, or enum.

When importing a module using export =, TypeScript-specific import let = require("module") must be used to import the module.

In your case it should be:

import md5 = require("md5");

If you're targetting es6 then you need to do:

const md5 = require("md5");

(or let or var of course).
