Cannot resolve typings included in npm package when using "moduleResolution": "classic"

[mjbvz]

From microsoft/vscode#34346

TypeScript Version: 2.5.2

Code
In a new project

$ npm init -y
$ npm install axios

import axios from 'axios';

{
    "compilerOptions": {
        "strict": true,
        "module": "amd",
        "moduleResolution": "classic"
    }
}

Expected behavior:
axios includes its own typings so these should be used for the import

Actual behavior:
Module axios cannot be resolved.

"moduleResolution": "node" fixes the problem

[mhegazy]

that is by design. do not use classic unless you have to. the reason it is there is purely back compat.

[mjbvz]

Ok, is there a way to work around this without changing the resolution to node?

[mhegazy]

add a path mapping entry for module imports.

Thanks @mhegazy! I'll follow up with the user who opened this bug back on the vscode repo
