Problem Overview

Integrating TypeScript with Node.js can significantly enhance your development experience by providing static typing, which helps catch errors during compile time. Here's how to set it up:

Install TypeScript: First, you need to install TypeScript globally or as a project dependency. Run the following command:
```
npm install -g typescript
```

Initialize TypeScript: Create a tsconfig.json file in your project root to configure TypeScript options:

{ "compilerOptions": { "target": "es6", "module": "commonjs", "strict": true, "esModuleInterop": true } }

Rename Files: Change your JavaScript files’ extensions from .js to .ts. If you use JSX, rename them to .tsx.
Compile TypeScript: Use the command below to compile your TypeScript files into JavaScript:
```
tsc
```
Run Your Application: You can run your compiled JavaScript files using Node.js:
```
node dist/index.js
```

Using TypeScript with Node.js allows you to benefit from better tooling, improved refactoring, and enhanced collaboration among team members.
