First Web API Tutorial

Welcome to the World of Web Development

This tutorial will guide you through the process of creating your first web API. Let's get started!

Step 1: Setting Up Your Environment

You'll need a code editor like VS Code or Sublime Text. Also, you'll need Node.js and npm installed. See the instructions at Node.js.

Step 2: Creating Your API

Let's create a simple API endpoint that returns 'Hello, World!'

Step 3: Implementing the API

Here's the code for your API endpoint:


function hello(name) {
  return "Hello, " + name + "!";
}

module.exports = hello;

Step 4: Testing Your API

Now, let's test your API endpoint:

Step 5: Saving Your Code

Save this code as a file named 'api.js' in the same directory as your HTML file.

Step 6: Running the API

Open your terminal, navigate to the directory where you saved 'api.js', and run the command: `node api.js`
