eslint-plugin-barrels

Plugin with prohibition of import / export from barrel files with specific relative path.

Motivation

Twice in my life Webpack failed build of Angular application with unexpected error because of import from barrel file like this:

import { smth } from '..';

If I changed import to particular path like this:

import { smth } from './smth.ts';

It would work.

[!NOTE]
There were not circular dependencies in my files. Crash depended only on path.

Unfortunately, I didn't found some issues or questions on Stack Overflow with same problem, so you should take my word for it.
