This will create a package.json file with default settings based on your npm configuration.
Creating a Minimal Server with ExpressOnce your package.json is set up, let’s add Express to your project:

shell

npm install express dotenv

Now, create a basic Express server in an index.js file:

javascript

const express = require('express'); const app = express(); const PORT = process.env.PORT || 8000;app.get(‘/’, (req, res) => {
res.send(‘Hello, World!’);
});app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});

To start the server, run:

shell

node index.js
Installing TypeScriptBegin by installing TypeScript as a development dependency, along with type declaration packages for Express and Node.js:

shell

npm i -D typescript @types/express @types/node

These packages ensure TypeScript understands the type definitions for Express and Node.js.
Generating tsconfig.jsonTypeScript projects rely on a tsconfig.json file for configuration. Generate it using:

shell

npx tsc --init

This file provides various configuration options, including the target JavaScript version, module system, strict type-checking, and more. Be sure to specify an outDir for your compiled code.

Here’s a snippet of the tsconfig.json file:

json

{ "compilerOptions": { "target": "es2016", "module": "commonjs", "strict": true, "esModuleInterop": true, "skipLibCheck": true, "forceConsistentCasingInFileNames": true, "outDir": "dist" } }
Creating an Express Server with a .ts ExtensionRename your index.js file to index.ts to indicate it’s a TypeScript file. Modify the code to:

typescript

import express from 'express'; import dotenv from 'dotenv';dotenv.config();const app = express();
const PORT = process.env.PORT || 8000;

app.get(‘/’, (req, res) => {
res.send(‘Hello, TypeScript World!’);
});

app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
Watching for File Changes and BuildingEnhance your development workflow with nodemon and concurrently. Install them as dev dependencies:

shell

npm i -D nodemon concurrently

Add the following scripts to your package.json:

json

"scripts": { "start": "node dist/index.js", "dev": "concurrently \"npm run watch-ts\" \"npm run start\"", "watch-ts": "tsc -w", "build": "tsc" }

Run your development server using:

shell

npm run dev

nodemon will automatically restart your server upon file changes.

TypeScript, a powerful superset of JavaScript, has been revolutionizing the world of web development since its inception in 2011. Its introduction brought static typing capabilities to JavaScript, significantly enhancing code quality and developer productivity. Today, TypeScript has become the go-to choice for numerous developers and organizations, whether they are crafting code for browsers or server runtime environments like Node.js or Deno.

In this comprehensive guide, we will explore the process of seamlessly integrating TypeScript into your Node.js projects. While TypeScript has native support in Deno, achieving the same level of integration in Node.js requires a bit of extra effort. We will dive deep into the steps required to bring TypeScript’s type checking and safety features into your Node.js applications.

Prerequisites

Before embarking on this TypeScript and Node.js journey, it’s essential to ensure that you have the necessary tools in place. Please follow these prerequisites to set up your development environment:

Node.js and npm Installation: Make sure you have a recent version of Node.js and npm installed on your system. For reference, we tested this setup with Node.js v16.14.2 and npm v8.5.0.
TypeScript Familiarity: This tutorial assumes a basic understanding of TypeScript syntax and its advantages. If you are new to TypeScript, it’s advisable to acquaint yourself with its benefits before proceeding.

Step 1: Downloading the Demo Project

To illustrate the integration process effectively, we’ll utilize a demo Node.js application. This application reports the real-time price of Bitcoin in various currencies, including cryptocurrencies and fiat currencies. Of course, you can adapt the concepts discussed in this article to any Node.js project of your choice.

Let’s get started by cloning the demo project to your local machine. Open your terminal and execute the following command:

bash

git clone <repository_url>

In the next step, we will install and configure the TypeScript compiler within our Node.js application.

Step 2: Installing and Configuring TypeScript

Now that we have the demo application cloned and ready, let’s proceed with the installation and configuration of TypeScript. Follow these steps to ensure TypeScript is seamlessly integrated into your project:

2.1 Install TypeScript Locally

It’s recommended to install TypeScript locally within your project. This approach ensures that the TypeScript version used is consistent across different environments and developers. Given TypeScript’s frequent updates, this precaution avoids potential compatibility issues.

Run the following command within your project directory:

bash

npm install typescript --save-dev

This command installs TypeScript as a development dependency and registers it in your project’s package.json file.

2.2 Create a tsconfig.json File

Before we can start compiling our TypeScript source files, we need to set up a TypeScript configuration file named tsconfig.json. Attempting to compile TypeScript without this configuration file will result in errors. While you can specify command-line flags, using a config file offers greater convenience.

To create the tsconfig.json file, follow these steps:

Open your text editor and create a new file named tsconfig.json in the root directory of your project.
Paste the following configuration into tsconfig.json:

json

{

"compilerOptions": {

"target": "ESNext",

"module": "CommonJS",

"strict": true,

"esModuleInterop": true,

"skipLibCheck": true,

"forceConsistentCasingInFileNames": true,

"outDir": "./dist"

},

"include": ["src/**/*.ts"],

"exclude": ["node_modules"]

}

This configuration sets up TypeScript to target the latest ECMAScript version (ESNext) and compiles modules using CommonJS. It enforces strict type checking, enables ES module interop, and specifies the output directory for compiled files.

With TypeScript installed and configured, your Node.js project is now ready to benefit from the safety and productivity enhancements it provides.

Conclusion

In this tutorial, we laid the foundation for integrating TypeScript into your Node.js projects seamlessly. With TypeScript installed and a tsconfig.json file in place, your code is poised to benefit from static typing and improved code quality.

In the upcoming sections, we will delve deeper into TypeScript integration, covering topics such as writing TypeScript code, setting up build processes, and incorporating TypeScript into various Node.js project structures. Stay tuned to harness the full power of TypeScript in your Node.js development endeavors.
