Travelbase Backend (Intern Training Project)

Welcome to the Travelbase Backend training project.

This repository is designed to help you get familiar with:

• Fastify (backend framework)
• API design
• Request/response lifecycle
• Writing clean, structured backend code
• Understanding how production APIs are built

This is not a full production system, but a simplified environment to help you ramp up.

🚀 Getting Started

1. Install Dependencies

npm install

---

2. Start Development Server

npm run dev

The server will start at:

http://localhost:3000

---

3. Run Tests

npm run test

---

🧠 What You Are Expected To Learn

Over the next few weeks, focus on understanding:

1. Fastify Basics

• What is Fastify?
• How routes are defined
• How requests are handled
• How responses are returned

2. API Structure

• Routes vs Services
• Separation of concerns
• Clean code organization

3. Request Lifecycle

• Incoming request
• Validation
• Processing logic
• Response

4. Debugging

• Reading logs
• Fixing errors
• Understanding stack traces

🧪 Your First Tasks

Start with these:

Task 1: Run the Project

• Install dependencies
• Start the server
• Confirm it works in the browser

---

Task 2: Understand a Route

• Open routes/
• Pick any route
• Trace:
  • What URL it listens to
  • What it returns

---

Task 3: Modify a Response

• Change a response message
• Restart the server
• Verify the change

---

Task 4: Create a New Route

Example:

fastify.get('/hello', async (request, reply) => {
  return { message: 'Hello World' }
})

---

⚠️ Important Rules

• Do NOT copy code blindly — understand it
• Ask questions early
• Break things and fix them (this is how you learn)
• Keep your code clean and readable

---

📚 Resources

• Fastify Docs: https://fastify.dev/docs/latest/
• Node.js Docs: https://nodejs.org/en/docs

---

🎯 Goal

By the end of this training, you should be able to:

• Build simple APIs
• Understand backend flow
• Read and modify real-world backend code
