Lightweight dependency injection container for JavaScript/TypeScript, with asynchronous resolution

import { __awaiter, __generator } from "tslib";
export default function instanceCachingFactory(factoryFunc) {
    var _this = this;
    var instance;
    return function (dependencyContainer) { return __awaiter(_this, void 0, void 0, function () {
        return __generator(this, function (_a) {
            if (instance == undefined) {
                instance = factoryFunc(dependencyContainer);
            }
            return [2, instance];
        });
    }); };
