javascript - Webpack typescript import es indefinido

Estoy empaquetando esta clase individual con webpack, sin embargo, cuando la importo en mi proyecto dice que está indefinida. He estado intentando un par de cosas, pero simplemente no lo estoy haciendo bien.

miclase.ts

export class Dyn {

    abc: any;

    constructor(drawCallback, options?) {

    }

    text(a){
        this.abc = a;
        console.log(this.abc);
    }
}

ts.config

{
    "compilerOptions": {
        "outDir": "./src2/js",
        "declaration": true,
        "baseUrl": "src",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "declarationDir": "./src2/@types",
        "sourceMap": false,
        "noImplicitAny": false,
        "module": "commonjs",
        "target": "es5"
    },
    "include": [
        "./src2/**/*"
    ],
    "exclude": [
        "node_modules"
    ]
}

webpack.config.js

module.exports = {
    entry: "./src2/myclass.ts",
    output: {
        filename: "myclass.js",
        path: __dirname + "/dist"
    },
    // Enable sourcemaps for debugging webpack's output.
    //devtool: "source-map",

    resolve: {
        // Add '.ts' and '.tsx' as resolvable extensions.
        extensions: [
            ".ts"
        ]
    },

    module: {
        loaders: [
            // All files with a '.ts' or '.tsx' extension will be handled by 'awesome-typescript-loader'.
            {
                test: /\.ts?$/, loader: "awesome-typescript-loader",
                exclude: /node_modules/
            },
            // All output '.js' files will have any sourcemaps re-processed by 'source-map-loader'.
            /*{
                enforce: "pre", test: /\.js$/, loader: "source-map-loader"
            },*/

        ],
    },
    // When importing a module whose path matches one of the following, just
    // assume a corresponding global variable exists and use that instead.
    // This is important because it allows us to avoid bundling all of our
    // dependencies, which allows browsers to cache those libraries between builds.
    externals: {    
    },
};

libraryTarget: "umd"

agregar a la parte de output en webpack.config.js soluciona este problema
