Object result of import all from module has no index signature #16248
Description
TypeScript Version: 2.3.4
Given an actions module where each exported member satisfies the type type MyFn = (...args: any[]) => any, when I collect those exports using import *, the resulting object has no index signature, leading to unwanted type errors.
Code
import * as actions from 'actions';
type MyFn = (...args: any[]) => any;
type MyMap = { [key: string]: MyFn };
const myMap: MyMap = actions;Expected behavior:
No error.
Actual behavior:
Type 'typeof "/Users/OliverJAsh/Development/unsplash-web/app/actions/index"' is not assignable to type 'MyMap'.
Index signature is missing in type 'typeof "/Users/OliverJAsh/Development/unsplash-web/app/actions/index"'.

One workaround is to spread the object:

Just ran into the same problem. Thanks for the workaround.
