Leveraging TypeScript in Node.js Projects: A Comprehensive Guide

Node.js is a powerful runtime that has revolutionized backend development, enabling developers to build scalable and efficient applications with JavaScript. However, as projects grow, managing a large codebase with JavaScript’s dynamic typing can become challenging. This is where TypeScript steps in, offering static typing and a suite of developer-friendly features to streamline Node.js development.

In this article, we’ll explore the benefits of using TypeScript in Node.js projects and provide practical examples to help you get started.

What is TypeScript?

TypeScript is a statically typed superset of JavaScript that compiles to plain JavaScript. Developed by Microsoft, it introduces type definitions to JavaScript, making your code more robust, maintainable, and error-free. It integrates seamlessly with Node.js, enhancing your development experience.

Why Use TypeScript with Node.js?

1. Static Typing for Error Prevention
   With TypeScript, you define variable types explicitly, catching potential errors at compile time rather than runtime.

const sum = (a: number, b: number): number => a + b; 
console.log(sum(5, 10)); // 15 // console.log(sum(5, "10")); 
// Error: Argument of type…
