To put it in perspective, if traditional coding is building a house alone, Vibe Coding is building a house while conversing with a team of experts. You say “I need this feature” and AI implements it immediately.
What You’ll Learn
- Understand the concept of AI Vibe Coding
- Learn how to use Cursor, Copilot, and Claude
- Master effective prompt writing techniques
- Understand practical workflows
Reality in Practice
When learning development, everything seems clean and theoretical. But practice is different. You wrestle with legacy code, chase tight deadlines, and face unexpected bugs. The content covered in this article was initially learned as theory, but it was through applying it to actual projects that I realized “Ah, this is why it’s designed this way.” What stands out in my memory is the trial and error from my first project. I did everything by the book but couldn’t figure out why it wasn’t working, spending days struggling. Eventually, through a senior developer’s code review, I discovered the problem and learned a lot in the process. In this article, I’ll cover not just theory but also the pitfalls you might encounter in practice and how to solve them.

What is Vibe Coding?
Traditional Coding vs Vibe Coding
Traditional Coding:
1. Google search → Stack Overflow
2. Read documentation
3. Write code
4. Debug
5. Refactor
Time: 2-3 hours
Vibe Coding:
1. Request to AI: "Create a TODO app with React"
2. AI generates code
3. Feedback: "Add dark mode"
4. AI immediately modifies
Time: 10-15 minutes
Core of Vibe Coding
Natural Language-Based Development:
Traditional:
for (int i = 0; i < arr.size(); i++) {
if (arr[i] % 2 == 0) {
result.push_back(arr[i]);
}
}
Vibe Coding:
"Filter only even numbers from the array"
→ AI automatically generates optimal code

Prompt Engineering
How to Write Effective Prompts
Bad Prompt:
"Create login functionality"
Good Prompt:
"Implement login functionality with Next.js 14 App Router.
Requirements:
- Email/password login
- JWT token-based authentication
- Persist login state (localStorage)
- Error message on login failure
- Input validation with Zod
- Styling with Tailwind CSS
File structure:
- app/login/page.tsx (login page)
- app/api/auth/login/route.ts (API)
- lib/auth.ts (JWT utility)
"
Prompt Patterns
1. Role Assignment
"You are a senior backend developer.
Design a RESTful API with Node.js and PostgreSQL."
2. Provide Context
"The current project is based on Express.js,
and uses Prisma ORM.
Add a Post model to the existing User model and set up a 1:N relationship."
3. Provide Examples
"Create API responses in the following format:
{
"success": true,
"data": { ... },
"error": null
}
4. Specify Constraints
"Use TypeScript,
minimize external libraries,
and add JSDoc comments to all functions."
Multi-Turn Conversation Strategy
Step 1: Big Picture
"Design a blog system architecture"
Step 2: Specification
"Write the database schema for the User model with Prisma"
Step 3: Implementation
"Implement the signup API endpoint"
Step 4: Improvement
"Add email duplicate check and hash passwords with bcrypt"

Best Practices
1. Use AI as a Pair Programmer
❌ Bad Usage:
"Create entire project" → Copy-paste → Done
✅ Good Usage:
"Design User model"
→ Review and feedback
→ "Add password hashing"
→ Review and learn
→ Repeat
2. Context Management
In Cursor:
@filename - Include specific file
@foldername - Include entire folder
@docs - Include documentation
@web - Include web search results
Example:
"@app.py @models.py Connect these two files
and add user authentication functionality"
3. Incremental Improvement
Step 1: "Implement basic functionality"
Step 2: "Add error handling"
Step 3: "Write test code"
Step 4: "Optimize performance"
Step 5: "Add documentation"
4. Leverage Code Review
In Cursor:
"@app.py Review this code.
Analyze from the following perspectives:
1. Security vulnerabilities
2. Performance issues
3. Code smells
4. Improvement suggestions"
→ AI provides detailed review
5. Use as a Learning Tool
"Explain this code step by step"
"Explain why this method is better"
"Are there other approaches?"
"What are the pros and cons of this pattern?"
→ Learn deeply through conversation with AI
Troubleshooting
1. AI Generates Incorrect Code
Problem:
AI-generated code doesn't work
Solution:
1. Copy error message
2. "Fix this error" + error message
3. AI provides corrected code
Or:
"Explain why this code doesn't work"
→ Identify cause then request fix
2. Insufficient Context
Problem:
AI doesn't understand project structure
Solution:
In Cursor:
1. Include full structure with @foldername
2. Write project description in README.md
3. Tell AI "First understand the project structure"
3. Inconsistent Code
Problem:
AI generates code with different styles each time
Solution:
Create .cursorrules file in project root:
"""
Coding rules:
- Use TypeScript
- Functional programming style
- Follow ESLint + Prettier
- Add JSDoc to all functions
- Handle errors with try-catch
"""
→ AI follows rules
4. Security Issues
Problem:
AI generates code with security vulnerabilities
Solution:
"Analyze security vulnerabilities in this code"
"Review based on OWASP Top 10"
"Add SQL Injection defense code"
→ Modify to security-hardened code
