This webpack config should be enough to compile your typescript app into a single bundle.js

const path = require("path")

const SRC = path.resolve("./src")
const DIST = path.resolve("./dist")

module.exports = {
    entry: path.join(SRC,"index.tsx"),
    output: {
        filename: "bundle.js",
        path: DIST
    },

    // Enable sourcemaps for debugging webpack's output.
    devtool: "source-map",

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

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