Typescript - ReferenceError: exports is not defined

Question

In my console I keep getting ReferenceError: exports is not defined as an error.

Code:

app.ts:

import {IDetails} from "./interfaces/IDetails";

class MyClass implements IDetails{
    constructor(){}

    public render (elem: string, text: string) {
        let el: HTMLElement = document.querySelector(elem);
        el.textContent = text;
        el.innerText = text;
    }
}

window.onload = () => {
    let myClass = new MyClass();
    myClass.render('body', 'Hello World!');
};

IDetails.ts:

export interface IDetails {
    elem: string,
    text: string
}

tsconfig.json:

{
  "compilerOptions": {
    "outDir": "./build/",
    "sourceMap": true,
    "noImplicitAny": false,
    "module": "commonjs",
    "target": "es5",
    "removeComments": true,
    "allowJs": true
  }
}

webpack.config.js:

module.exports = {
    entry: './index.ts',
    output: {
        filename: 'bundle.js',
        path: __dirname
    },
    watch: true,
    module: {
        rules: [
            {
                test: /\.tsx?$/,
                loader: "ts-loader",
                options: {
                    transpileOnly: true
                }
            }
        ]
    },
    resolve: {
        extensions: [".tsx", ".ts", ".js"]
    },
};

What am I doing wrong here?

EDIT : I have edited my question with webpack.config.js and tsconfig.json . It might also be worthy to notice that I'm viewing the files directly from Webstorm in my Chrome browser. Could that be an issue?

Thank you.

Answer 1

It may be related to your Typescript config options if you're exporting CommonJS modules. You can fix this by running your bundle through a command line utility called Browserify. See http://thejsguy.com/javascript/browserify/2015/01/05/browserify-getting-started.html

Try to set "allowJs": false

Or to exclude the webpack config file from the typescript compiler using exclude https://www.typescriptlang.org/docs/handbook/tsconfig-json.html
