It may have already been fixed. --> **TypeScript Version:** 3.3.0-dev.20190118 <!-- Search terms you tried before logging this (so others can find this issue more easily) --> **Search Terms:** jsdoc import module.exports has no exported member **Code** **a.js** ```js class A {} module.exports = {A} ``` **b.js** ```js // @ts-check class B { // In the JSDoc below, VSCode intellisense does not recognize parameter a as type A. // Instead it shows the error: // Namespace '".../a".export=' has no exported member 'A' /** * @param {import('./a').A} a */ constructor (a) { this.a = a } } ``` **Expected behavior** Parameter `a` of the `constructor` should be recognized as type `A`, which is accessible via the `A` property of `module.exports` from `a.js`. **Actual behavior** Intellisense reports the error: Namespace '".../a".export=' has no exported member 'A'. **Notes** `@param {import('./a')} a` does not give an error, but it resolves to type `{A: typeof A}` instead of `A`. If `a.js` is modified with `module.exports = A`, then `import('./a')` resolves to `A`, however this restricts `a.js` to only exporting one type.
