If you're a developer, you know that starting a new project can be a daunting task. Setting up your development environment, installing the necessary packages, configuring the build tools, and more can take a lot of time and effort. Fortunately, TypeScript makes it easy to create a new Node project without all the hassle. In this post, we'll walk you through the steps to generate a quick Node project with TypeScript.

Here are the steps you need to follow:

Step 1: Install Node.js and npm if you haven't done it yet.

Step 2: Open a terminal window and navigate to the folder where you want to create your project.

Step 3: Run the following command to create a new folder for your project:

    mkdir my-project && cd my-project

Step 4: Initialize npm for your project using the following command:

    npm init -y

Step 5: Install the necessary dependencies for a TypeScript project:

    npm install --save-dev typescript ts-node @types/node

Step 6: Create a TypeScript configuration file named tsconfig.json in your project's root directory with the following content:

{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs",
    "outDir": "dist",
    "strict": true,
    "esModuleInterop": true
  },
  "include": ["src/**/*.ts"],
  "exclude": ["node_modules"]
}

Step 7: Create a folder named src in the root directory of your project, and create a TypeScript file named index.ts inside it:

    mkdir src && touch src/index.ts // linux
    mkdir src ;; New-Item -Type File src/index.ts // windows

Step 8: Open the index.ts file in your favorite code editor and write some TypeScript code, for example:

const message: string = 'Hello, TypeScript!';
console.log(message);

Step 9: In your package.json file, add a new script to compile and run your TypeScript code:

{
  "scripts": {
    "start": "ts-node src/index.ts",
    "build": "tsc"
  }
}

Step 10: Finally, run the following command to compile and run your TypeScript code:

npm run start

This will compile your TypeScript code into JavaScript and run it using ts-node. You can also run the build script to compile your code and generate JavaScript files in the dist folder:

npm run build

Thanks and have a great day ahead!
