Can I narrow the type of module imported using require in TypeScript?

Question

Using the TypeScript 2.7.1 language service in VS Code, I can get hinting for a module imported into a JavaScript file as:

const aModule = require('./aModule')

However, the type inference from the module includes the generic [x: string]: any;

Which means that I can get autocomplete for valid exports from the module, but cannot get a warning if I use:

aModule.something_that_doesnt_exist()

Is there a way to specify that the object is not extendable?

试试这个语法：

import * as aModule from './aModule';
