Vibe Coding: Collins Dictionary's Word of the Year and What It Means for the Future of Programming

Hello HaWkers! Collins dictionary just announced "Vibe Coding" as the word of the year for 2025, officially marking an unprecedented transformation in how we write code. If you haven't heard about this term yet, get ready: this trend is redefining what it means to be a developer.

Have you stopped to think about how AI is changing not just what we do, but how we do it? "Vibe Coding" isn't just another passing buzzword - it's a movement capturing the essence of a new era in programming.

What Is Vibe Coding?

"Vibe Coding" is a term describing the practice of programming with the help of artificial intelligence tools, where developers express their intentions in natural language and AI transforms those ideas into functional code. It's like having a conversation about what you want to build and watching code appear magically.

Collins' choice wasn't random. According to the dictionary, the term perfectly captures the spirit of 2025: an era where the barrier between thought and implementation is rapidly dissolving.

The Silent Revolution Already Happening

While many developers still debate whether AI will "replace programmers," a new generation is already using AI tools to multiply their productivity:

GitHub Copilot and Similar Tools:

Used by over 50 million developers globally
Writes up to 46% of code in some projects
Reduces debugging time by an average of 30%

Claude Code and Cursor:

Allows creating complete applications through conversation
Understands entire project context
Automatically suggests architectures and patterns

ChatGPT and Bard:

Explain complex code in seconds
Convert between programming languages
Generate unit tests automatically

But here's the interesting part: Vibe Coding isn't about writing less code. It's about programming at a higher level of abstraction, focusing on logic and architecture while AI handles implementation details.

How It Works in Practice

Let's see a real example of Vibe Coding. Imagine you need to create a JWT authentication system in Node.js. Instead of spending hours configuring libraries and writing boilerplate, you could do this:

// AI Prompt: "Create a complete JWT authentication system with:
// - User registration with password hashing using bcrypt
// - Login returning JWT token valid for 24h
// - Token verification middleware
// - Example protected routes
// - Robust error handling"

// AI generates something like:

const jwt = require('jsonwebtoken');
const bcrypt = require('bcrypt');
const express = require('express');
const router = express.Router();

// Configuration
const JWT_SECRET = process.env.JWT_SECRET || 'your-secret-key';
const JWT_EXPIRES_IN = '24h';
const SALT_ROUNDS = 10;

// User registration
router.post('/register', async (req, res) => {
  try {
    const { email, password, name } = req.body;

    // Basic validation
    if (!email || !password || !name) {
      return res.status(400).json({
        error: 'Email, password and name are required'
      });
    }

    // Hash password
    const hashedPassword = await bcrypt.hash(password, SALT_ROUNDS);

    // Save user (here you would use your database)
    const user = {
      id: Date.now(),
      email,
      name,
      password: hashedPassword,
      createdAt: new Date()
    };

    // Generate token
    const token = jwt.sign(
      { id: user.id, email: user.email },
      JWT_SECRET,
      { expiresIn: JWT_EXPIRES_IN }
    );

    res.status(201).json({
      message: 'User created successfully',
      token,
      user: {
        id: user.id,
        email: user.email,
        name: user.name
      }
    });
  } catch (error) {
    res.status(500).json({ error: 'Error creating user' });
  }
});

// Login
router.post('/login', async (req, res) => {
  try {
    const { email, password } = req.body;

    // Find user (use your database here)
    const user = await findUserByEmail(email);

    if (!user) {
      return res.status(401).json({ error: 'Invalid credentials' });
    }

    // Verify password
    const passwordMatch = await bcrypt.compare(password, user.password);

    if (!passwordMatch) {
      return res.status(401).json({ error: 'Invalid credentials' });
    }

    // Generate token
    const token = jwt.sign(
      { id: user.id, email: user.email },
      JWT_SECRET,
      { expiresIn: JWT_EXPIRES_IN }
    );

    res.json({
      message: 'Login successful',
      token,
      user: {
        id: user.id,
        email: user.email,
        name: user.name
      }
    });
  } catch (error) {
    res.status(500).json({ error: 'Login error' });
  }
});

// Authentication middleware
const authenticateToken = (req, res, next) => {
  const authHeader = req.headers['authorization'];
  const token = authHeader && authHeader.split(' ')[1];

  if (!token) {
    return res.status(401).json({ error: 'Token not provided' });
  }

  jwt.verify(token, JWT_SECRET, (err, user) => {
    if (err) {
      return res.status(403).json({ error: 'Invalid or expired token' });
    }

    req.user = user;
    next();
  });
};

// Example protected route
router.get('/profile', authenticateToken, async (req, res) => {
  try {
    // req.user contains token data
    const user = await findUserById(req.user.id);

    if (!user) {
      return res.status(404).json({ error: 'User not found' });
    }

    res.json({
      user: {
        id: user.id,
        email: user.email,
        name: user.name,
        createdAt: user.createdAt
      }
    });
  } catch (error) {
    res.status(500).json({ error: 'Error fetching profile' });
  }
});

module.exports = { router, authenticateToken };

The Three Phases of Vibe Coding

1. Exploration (Conversation Phase)

You talk with AI about what you need to build:

"I need a shopping cart system"
"What are the best practices for this?"
"How to implement shipping calculation?"

AI not only responds but questions your choices, suggests alternatives and explains trade-offs.

2. Implementation (Generation Phase)

AI generates code based on the full conversation context:

// Prompt: "Create a function that calculates shipping based on ZIP code,
// weight and package dimensions, using Postal Service API"

const calculateShipping = async (zipCode, weight, dimensions) => {
  // Input validation
  if (!validateZipCode(zipCode)) {
    throw new Error('Invalid ZIP code');
  }

  if (weight <= 0 || dimensions.someInvalidDimension()) {
    throw new Error('Invalid weight or dimensions');
  }

  try {
    // Query Postal Service API
    const response = await fetch('https://api.postalservice.com/shipping', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${process.env.POSTAL_API_KEY}`
      },
      body: JSON.stringify({
        originZip: process.env.ORIGIN_ZIP,
        destinationZip: zipCode,
        weight: weight,
        length: dimensions.length,
        height: dimensions.height,
        width: dimensions.width,
        format: 1, // Box/package
        services: ['EXPRESS', 'STANDARD'] // Multiple options
      })
    });

    if (!response.ok) {
      throw new Error('Error querying shipping');
    }

    const data = await response.json();

    // Process and return shipping options
    return data.services.map(service => ({
      type: service.name,
      price: parseFloat(service.price),
      deliveryDays: parseInt(service.deliveryTime),
      code: service.code
    })).sort((a, b) => a.price - b.price); // Sort by price

  } catch (error) {
    console.error('Shipping calculation error:', error);
    throw new Error('Could not calculate shipping. Please try again.');
  }
};

// ZIP code validation helper
const validateZipCode = (zip) => {
  const cleanZip = zip.replace(/\D/g, '');
  return cleanZip.length === 5 && /^\d{5}$/.test(cleanZip);
};

module.exports = { calculateShipping };

3. Refinement (Iteration Phase)

You iterate over the generated code:

"Add Redis cache with 1 hour TTL"
"Implement retry with exponential backoff"
"Add unit tests"

AI understands the full context and applies changes consistently.

Solution: Always review and understand each line. Use AI as teacher, not as shortcut.

2. Security and Privacy

Danger: Sending proprietary code to external APIs.

Solution: Use on-premise tools or sanitize sensitive data.

3. Inconsistent Quality

Danger: AI can generate code that works but isn't ideal.

Solution: Establish specific code review standards for AI-generated code.

4. Over-Engineering

Danger: AI tends to generate more complex solutions than necessary.

Solution: Clearly specify desired complexity level in prompt.

Are there better alternatives?
What are the trade-offs?
Does this fit my project context?

The Debate: Will Programmers Disappear?

The question everyone asks: "Will AI replace programmers?"

The answer is nuanced:

Won't replace because:

Someone needs to understand what to build
Architecture decisions require business understanding
Code review requires human expertise
Context and creativity are human

Will transform because:

Repetitive tasks will be automated
Entry barriers decrease dramatically
Experienced developer productivity multiplies
Focus shifts from "how to code" to "what to build"

The truth: Programmers who use AI will replace programmers who don't.
