📆 Day 90:
MongoDB is a NoSQL database, and with Mongoose, working with it in Node becomes super easy and structured!

💡 Why?
📦 NoSQL = Flexible, schema-less storage
🔗 Mongoose = Object mapping with built-in validation
🚀 Ideal for dynamic, fast-changing data in modern apps

[Tattvam 🚀 @ttvmcodes]

📆 Day 90: Working with MongoDB 🗃️
Connected Node to MongoDB!

✅ Used Mongoose
✅ Created schema & model
✅ Inserted documents

💡 NoSQL + Node = Dynamic Data!

📆 Day 89:
A RESTful API lets your frontend and backend talk using HTTP methods (GET, POST, PUT, DELETE) and JSON.

💡 Why RESTful APIs?

🔗 Connect frontend to backend
📤 Communicate using JSON
✅ Use proper HTTP status codes (200, 201, 404, etc.)
🧱 Base for modern web apps

[Tattvam 🚀 @ttvmcodes]

📆 Day 89: RESTful APIs with Express 🌐
Built a simple REST API!

-GET, POST, PUT, DELETE
-Routes & JSON responses
-Status codes

💡 Connects frontend to backend!

📆 Day 88:
Express.js is a minimal, fast, and flexible Node.js framework that simplifies server creation and routing.🚀

💡 Why Use Express?
✅ Faster than raw Node HTTP server
✅ Cleaner routing
✅ Built-in middleware support
✅ Easy to scale with third-party packages

[Tattvam 🚀 @ttvmcodes]

📆 Day 88: Intro to Express.js 🚀
Express = minimal & powerful Node.js framework

✅ Easy routing
✅ Middleware support
✅ Fast development

💡 A must-know for backend devs!

📆 Day 87:
Middleware runs between a request (req) and a response (res).
Used for logging, auth, and parsing — especially in Express.js.

🛠️ Powered by Express
Middleware is a core part of Express.

It helps you:
🔍 Modify requests
✅ Add security
🧩 Use tools like morgan, cors

[Tattvam 🚀 @ttvmcodes]

📆 Day 87: Middleware in Node.js 🧱
Middleware = functions between req & res

✅ Logging
✅ Parsing
✅ Authentication

🛠️ Powered up with Express.js!

📆 Day 86: Routing in Node.js 🌐
Routing decides how your server responds to various URL requests.

💡 Summary:
-Manual routing is a good way to learn the basics.
-But for real-world apps, Express gives a cleaner and more powerful approach to routing!

[Tattvam 🚀 @ttvmcodes]

📆 Day 86: Routing in Node.js 🌐
Added basic routing manually!

🛣️ if/else or switch for URLs
🛠️ Later moved to Express for cleaner routes

💡 Routing is the brain of your server!

📆 Day 85: Creating Servers with HTTP 🖥️
Built a basic HTTP server!

✅ Used http.createServer()
✅ Handled routes
✅ Sent responses

💡 A core skill for any backend dev!
#100DaysOfCode #letsconnect #NodeJS #WebDevelopment #buildinpublic #JavaScript

[Tattvam 🚀 @ttvmcodes]

📆 Day 85:🖥️

Node.js lets you create a basic web server using the built-in http module — no external packages needed!

💡Why it matters?
Creating HTTP servers is a core backend skill.
You’ll later build on this with frameworks like Express, but this is the foundation!

📆Day 84:
Error handling keeps your app stable and safe. Here’s how to handle errors like a pro in Node.js!

🧠Use try-catch for sync code.
🧠Wrap await calls in try-catch for async errors.
🧠Create custom error for clearer responses.
🧠Use Express middleware to catch all errors.

[Tattvam 🚀 @ttvmcodes]

📆 Day 84: Error Handling in Node ❗
Learned to handle errors like a pro!

✅ Try-Catch (sync & async)
✅ Custom error classes
✅ Middleware for Express

🛡️ Don’t let bugs break your app!
