Setting up Express with TypeScript in 2026: A Comprehensive Guide for Northeast India

In the ever-evolving world of web development, staying updated with the latest technologies is crucial. This article provides a step-by-step guide on how to set up Express, a popular web application framework, with TypeScript, a powerful typed superset of JavaScript, in the year 2026. This guide is particularly relevant for developers in Northeast India, as it helps them keep pace with the global tech trends.

Prerequisites: Installing Node.js

Before starting, ensure you have Node.js installed. Version 20+ or later is highly recommended. To check if you have Node.js installed, type the command in your terminal: node --version

Step 1: Initializing the Project

Create the project directory and initialize the project using the following commands:

• mkdir express-typescript-project (This creates the project directory)
• cd express-typescript-project (This enters the project directory)
• npm init -y (This creates the package.json with the default settings)

Step 2: Installing Express Dependencies

Install Express and its corresponding dev dependencies using the following commands:

• npm install express (This installs Express as dependencies)
• npm install -D typescript @types/node @types/express (These install the necessary TypeScript types)

Step 3: Installing TypeScript

Install TypeScript and its run time using the following command:

• npm install --save-dev tsx (This installs TypeScript)

Step 4: Configuring TypeScript

Generate a tsconfig.json file to configure the TypeScript compiler using the following command:

• npx tsc --init (This initializes the TypeScript configuration)

Step 5: Creating the Index File

Create a src directory and add an index.ts file inside it using the following commands:

• mkdir src (This creates the source folder)
• touch src/index.ts (Creates the index.ts file)

Step 6: Updating the Scripts in your package.json file

Update the scripts section in your package.json file as follows:

  "scripts": { "dev": "tsx watch src/index.ts", "build": "tsc", "start": "node dist/server.js", "start:prod": "npm run build && npm start", "lint": "eslint .", "lint:fix": "eslint . --fix", "format": "prettier --write \"**/*.{ts,js,json,md,yml,yaml}\"" }  

Step 7: Running the Application

To run the application, use the following commands:

• npm run dev (For development)
• npm run build && npm start (For production)

Relevance to Northeast India and the Broader Indian Context

With the growing importance of technology in India, it is essential for developers in Northeast India to stay updated with the latest trends. By following this guide, they can enhance their skill set and contribute more effectively to the tech industry in India and beyond.

Conclusion

In conclusion, setting up Express with TypeScript in 2026 provides a robust foundation for developing web applications. By following the steps outlined in this guide, developers in Northeast India can stay ahead of the curve and contribute to the ongoing tech revolution in India.
