no-unused-modules does not work with export class

[ehmicky]

index.js:

import { Example } from './foo.js'
export { Example }

foo.js:

export class Example {}

.eslintrc.yml:

parserOptions:
  ecmaVersion: 2019
  sourceType: module
plugins: [import]
rules:
  import/no-unused-modules: [2, {missingExports: true}]

Then:

$ eslint
/home/user/example/foo.js
  1:1  error  No exports found                                 import/no-unused-modules

✖ 1 problem (1 error, 0 warnings)

However the following works:

class Example {}
export { Example }

eslint: 5.16.0
eslint-plugin-import: 2.17.3
node: 12.3.1
OS: Ubuntu 19.04

Thanks for the fix! 🎉

It seems like this same problem exists for export module Example, or am I misinterpreting?

[ljharb]

@nathanielcook export module is not valid syntax.

[nathanielcook]

@ljharb It is in TypeScript; sorry for not mentioning that.

In that case, please feel free to file a PR to add it :-)

By the way, I see now that the problem also exists for export enum and export interface.

Edit: export function as well.
