ERROR in node_modules/@types/koa/index.d.ts(104,14): error TS2694: Namespace '"url"' has no exported member 'URL'.

DefinitelyTyped/types/koa/index.d.ts

Line 28 in d0df8af

import * as url from "url";

Are you sure it's correct import here?

I solved the issue by changing it from

DefinitelyTyped/types/koa/index.d.ts

Line 104 in d0df8af

URL: url.URL;

to just

URL: URL;

Updating @types/node to newest version fixed this for me

I changed the URL: url.URL; to URL: url.Url; .
and solved.

Actually all you need to do is include @type/node to tsconfig compilerOptions

{
  "compilerOptions": {
    "types": [
      "node"
    ]
  }
}
