How to Run a Typescript File in 2025?

Running a TypeScript file remains a straightforward process in 2025, leveraging enhanced tools and new ESNext features for seamless development. By converting TypeScript (TS) into JavaScript (JS), you can execute your code in any runtime that supports JS. Below is a step-by-step guide to executing a TypeScript file efficiently:

Step-by-Step Guide

1. Install Node.js and TypeScript

Ensure you have the latest version of Node.js installed on your system, which comes bundled with npm (Node Package Manager) for easy installation of TypeScript:

1

npm install -g typescript

2. Create Your TypeScript File

You can write your TypeScript code in any text editor. For example, create a file named app.ts:

1
2

const greeting: string = "Hello, TypeScript 2025!";
console.log(greeting);

3. Compile TypeScript to JavaScript

Use the TypeScript compiler (tsc) to transform your TypeScript file into a JavaScript file:

1

tsc app.ts

This command generates an app.js file in the same directory, which contains the JavaScript version of your TypeScript code.

4. Execute the JavaScript File

Run the JavaScript file using Node.js:

1

node app.js

Upon successful execution, you should see the output:

1

Hello, TypeScript 2025!
