How to setup Node.js project with Typescript in 2023

Node.js is a popular runtime environment that allows developers to write server-side applications using JavaScript. One of the key features of Node.js is its ability to use Typescript, a superset of JavaScript that adds static typing and other useful features to the language.

Step 1: Install Node.js

Before setting up a Node.js project with Typescript, you need to install Node.js on your machine. You can download the latest version of Node.js from the official website and follow the installation instructions.

Step 2: Set up a new project

Once Node.js is installed, you can create a new project folder for your Typescript project. Open a terminal window and navigate to the project folder. Run the following command to initialize a new Node.js project:

npm init -y

Step 3: Install Typescript

Next, you need to install Typescript in your project. Run the following command in the terminal:

npm install typescript --save-dev

Step 4: Configure Typescript

Create a new file in your project folder called tsconfig.json and add the following configuration:

{"compilerOptions": {"target": "es6","module": "commonjs","outDir": "./dist"}}

Step 5: Write Typescript code

You can now start writing your Typescript code in the project. Create a new Typescript file with the extension .ts and write your code using TypeScript syntax.

Step 6: Compile Typescript to JavaScript

To compile your Typescript code to JavaScript, run the following command in the terminal:

tsc

Step 7: Run the Node.js project

Once the Typescript code is compiled to JavaScript, you can run the Node.js project using the following command:

node dist/yourfilename.js

That’s it! You have successfully set up a Node.js project with Typescript in 2023. Happy coding!
