Code
Input
export * from './test';
Output
var __createBinding = (this && this.__createBinding) || (Object.create ? (function(o, m, k, k2) {
if (k2 === undefined) k2 = k;
Object.defineProperty(o, k2, { enumerable: true, get: function() { return m[k]; } });
}) : (function(o, m, k, k2) {
if (k2 === undefined) k2 = k;
o[k2] = m[k];
}));
var __exportStar = (this && this.__exportStar) || function(m, exports) {
for (var p in m) if (p !== "default" && !exports.hasOwnProperty(p)) __createBinding(exports, m, p);
} /* There is a missing semi-colon here */
(function (factory) {
if (typeof module === "object" && typeof module.exports === "object") {
var v = factory(require, exports);
if (v !== undefined) module.exports = v;
}
else if (typeof define === "function" && define.amd) {
define(["require", "exports", "./test"], factory);
}
})(function (require, exports) {
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
__exportStar(require("./test"), exports);
});
When module target is configured UMD and helpers are emitted. The __exportStar
unnamed function declaration has a missing ;
, which causes an error during runtime Uncaught TypeError: (intermediate value)(…) is not a function
Expected behavior:
A semi-colon is added after the unnamed __exportStar
function declaration.
Actual behavior:
A semi-colon is missing from the output which cause a runtime error.
