How to Use Typescript with Webpack in 2025?

As web development continues to evolve, integrating TypeScript with Webpack has become essential for creating robust and scalable applications. In 2025, leveraging TypeScript’s powerful type system with Webpack’s bundling capabilities offers a seamless development experience. Here’s a comprehensive guide to setting up TypeScript with Webpack, ensuring your project is both efficient and well-optimized.

Why Use TypeScript with Webpack?

TypeScript provides advanced static typing, enhancing code quality and maintainability. When combined with Webpack, a powerful module bundler, you can streamline your build process, manage assets effectively, and improve your project’s performance.

mkdir my-typescript-app
cd my-typescript-app
npm init -y

2. Install Required Packages

Install TypeScript, Webpack, and related packages:

1

npm install --save-dev typescript ts-loader webpack webpack-cli

3. Configure TypeScript

Create a tsconfig.json for TypeScript configuration:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "outDir": "./dist"
  },
  "include": ["src"]
}

4. Set Up Webpack

Create a webpack.config.js file to configure Webpack:

const path = require('path');

module.exports = {
  entry: './src/index.ts',
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/,
      },
    ],
  },
  resolve: {
    extensions: ['.tsx', '.ts', '.js'],
  },
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
};

5. Create Your Source Files

Create a src folder and add your TypeScript files. For example, src/index.ts.

6. Build and Run

Add the following scripts to your package.json:

1

"scripts": {
  "build": "webpack",
  "start": "webpack serve --open"
}

Run the build process with:
