Starting with Node.js – It’s as Easy as Pie!
Step 1: Setup Your Lair (AKA Your Project Directory)
Just like every superhero needs a lair, every Node.js project needs a directory. Create a folder on your computer and name it something cool like “NodeNest” or “JavaScriptJungle”.
Step 2: Initiate the Secret Handshake (Run npm init)
Open your trusty sidekick, the terminal, and navigate to your project folder. Run npm init and answer the mystical questions. Voila, you’ve just created your package.json, the manifesto of your project!
Step 3: Writing Your First Spell (A Simple Script)
Create a file named app.js. Now, let’s write a spell that conjures a web server:
const http = require('http');
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello World\n');
});
const port = 3000;
server.listen(port, () => {
console.log(`Server running at http://localhost:${port}/`);
});Step 4: Bring it to Life! (Run Your App)
In the terminal, chant node app.js, and like magic, your server is alive!
