💻 Code
import {BAR} from 'bar';
import * as foo from 'foo';
export interface RootState {
[BAR]: string;
[foo.bar]: string;
}
🙁 Actual behavior
When compiled to ESNext module:
import { BAR } from 'bar';
import * as foo from 'foo';
when compiled to AMD with importHelpers it's interesting that __importStar appears
define(["require", "exports", "tslib", "bar", "foo"], function (require, exports, tslib_1, bar_1, foo) {
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
foo = tslib_1.__importStar(foo);
});
🙂 Expected behavior
output should be an entirely empty module, e.g. AMD should be
define(["require", "exports"], function (require, exports) {
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
});
ESNext should be
export {}
