How do I configure Webpack for a TypeScript project?

To configure Webpack for a TypeScript project, you'll need to install TypeScript and the necessary loaders. Start by running: npm install --save-dev typescript ts-loader webpack webpack-cli.

What should I include in my webpack.config.js file?

In your webpack.config.js, you should include the entry point, output configuration, and module rules for TypeScript. Here's a basic example:

const path = require('path');

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

Do I need a tsconfig.json file?

Yes, you need a tsconfig.json file to specify the TypeScript compiler options. You can create one with tsc --init and customize it as needed.

Can you give me an example of a simple tsconfig.json?

Sure! Here's a simple tsconfig.json:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules"]
}
