🚀 MyZubster Performance Optimization Guide

Complete guide to optimizing your MyZubster deployment – from database to CDN

---

📌 What is This Guide?

This guide covers everything you need to optimize MyZubster for production:

• ✅ Database optimization – Indexing, query optimization, connection pooling
• ✅ Caching strategies – Redis, in-memory, and CDN caching
• ✅ API optimization – Response compression, pagination, rate limiting
• ✅ Frontend optimization – Bundle size, lazy loading, image optimization
• ✅ Monitoring – Performance metrics and alerts
• ✅ Load testing – Simulate traffic and find bottlenecks

🗄️ Step 1: Database Optimization

1.1 PostgreSQL Indexing Strategy

sql
-- Users table
CREATE INDEX idx_users_email ON Users(email);
CREATE INDEX idx_users_username ON Users(username);
CREATE INDEX idx_users_role ON Users(role);

-- Skills table
CREATE INDEX idx_skills_seller ON Skills(sellerId);
CREATE INDEX idx_skills_category ON Skills(category);
CREATE INDEX idx_skills_created_at ON Skills(createdAt);

🚀 Step 2: Caching Strategy
2.1 Redis Cache Implementation
javascript

const redis = require('redis');

const client = redis.createClient({
  url: process.env.REDIS_URL || 'redis://localhost:6379',
});

const cache = (duration = 300) => {
  return async (req, res, next) => {
    const key = `cache:${req.originalUrl}`;
    try {
      const cachedData = await client.get(key);
      if (cachedData) {
        return res.json(JSON.parse(cachedData));
      }
      const originalSend = res.json;
      res.json = (data) => {
        client.setEx(key, duration, JSON.stringify(data));
        originalSend.call(res, data);
      };
      next();
    } catch (error) {
      next();
    }
  };
};

## ✅ Summary

| Issue | Cause | Solution |
|-------|-------|----------|
| **Liquid Syntax Error** | `{% raw %}` not recognized | Remove raw tags and use code fences |
| **Liquid Syntax Error** | `{{ }}` in code blocks | Wrap code in triple backticks |
| **Liquid Syntax Error** | Broken `{% raw %}` syntax | Type it manually or use HTML comments |

---

**The safest fix: Use triple backticks for all code blocks and skip `{% raw %}` entirely. DEV.to will not parse Liquid inside code blocks.**
