```javascript
// Manual index creation
db.createIndex('users', 'email'); // Fast email lookups
db.createIndex('users', 'age'); // Fast age range queries
db.createIndex('orders', 'userId'); // Fast user order lookups
// Auto-indexing via schema
db.createTable('products', {
id: { type: 'number', required: true, indexed: true },
name: { type: 'string', indexed: false },
category: { type: 'string', indexed: true }, // Auto-indexed
price: { type: 'number', indexed: true }, // Auto-indexed
inStock: { type: 'boolean', indexed: false }
});
```
### 📊 Performance Monitoring
Track and optimize your database performance:
```javascript
// Get detailed performance metrics
const metrics = db.getPerformanceMetrics();
console.log(metrics);
// {
// averageQueryTime: '0.45ms',
// totalQueries: 1250,
// indexUsage: 892,
// cacheHitRate: 0.85,
// tablesWithIndexes: 3,
// totalIndexes: 8
// }
// Built-in benchmarking
await db.benchmark(100000); // Test with 100K records

```javascript
// Performance-optimized bulk insert
const largeDataset = generateMillionRecords();
console.time('Bulk Insert');
await db.bulkInsert('analytics', largeDataset);
console.timeEnd('Bulk Insert');
// Bulk Insert: 2,345ms (1M records with chunking)
// Lightning-fast indexed queries on large datasets
const results = await db.whereOperator('score', '>', 800)
.where('category', 'premium')
.limit(100)
.get('analytics');
// Query time: 0.8ms (on 1M records with indexes)
```
### 🧠 Memory Management for Large Datasets
Rockdex DB intelligently manages memory to prevent browser crashes:
```javascript
// Automatic chunking and streaming for large datasets
const db = new RockdexDB({
chunkSize: 10000, // 10K records per chunk
maxMemoryChunks: 5 // Keep max 5 chunks in RAM
});
// Process millions of records without memory issues
db.setTable('bigdata', millionRecords);
// ✅ Automatically chunked into manageable pieces
// ✅ LRU eviction prevents memory overflow
// ✅ Lazy loading for optimal performance
```
### 📈 Performance Comparison

## 🚀 Quick Start
### Installation
```bash
npm install @odion-cloud/rockdex-db
```
### Basic Usage
```javascript
const RockdexDB = require('@odion-cloud/rockdex-db');
// Create database instance
const db = new RockdexDB({
storageMode: 'memory',
logging: true
});
// Create table and insert data
db.createTable('users');
db.insert('users', {
name: 'John Doe',
email: 'john@example.com',
age: 30
});
// Query with advanced conditions
const adults = db
.whereOperator('age', '>=', 18)
.orderBy('name')
.get('users');
console.log('Adult users:', adults);
```
## 🎯 Storage Modes
### Memory Mode (Default)
Perfect for temporary data, caching, and development:
```javascript
const db = new RockdexDB({
storageMode: 'memory',
logging: true,
timestamps: true
});
// Create tables and add data
db.createTable('users');
db.insert('users', {
name: 'Alice Smith',
email: 'alice@example.com'
});
```
### File Mode with Manual Tables
For persistent storage with complete control:
```javascript
// 1. Create your database structure manually
mkdir ./database
touch ./database/users.rdb
touch ./database/posts.rdb
touch ./database/orders.rdb
// 2. Configure Rockdex DB
const db = new RockdexDB({
storageMode: 'file',
storagePath: './database',
storageTable: ['users.rdb', 'posts.rdb', 'orders.rdb']
});
await db.ready(); // Wait for initialization
```
## 📚 Core Features
### Schema Validation
```javascript
const userSchema = {
name: { type: 'string', required: true },
email: { type: 'string', required: true, pattern: /@/ },
age: { type: 'number', min: 0, max: 120 },
role: { type: 'string', required: false }
};
db.createTable('users', userSchema);
// This will validate against schema
db.insert('users', {
name: 'John',
email: 'john@example.com',
age: 30
});
```
### Advanced Queries
```javascript
// Complex WHERE conditions
const results = db
.where('age', 25)
.whereOperator('salary', '>', 50000)
.whereIn('department', ['IT', 'HR'])
.whereLike('name', 'John%')
.orderBy('salary', 'DESC')
.limit(10, 0)
.get('employees');
// Aggregations
const avgSalary = db.avg('employees', 'salary');
const totalSales = db.sum('orders', 'amount');
const maxPrice = db.max('products', 'price');
// Grouping
const usersByDepartment = db.groupBy('employees', 'department');
```
### Transactions
```javascript
db.transaction(db => {
db.insert('users', userData);
db.insert('profiles', profileData);
// If any operation fails, all changes are rolled back
});
```
### Triggers
```javascript
db.createTrigger('users', 'beforeInsert', ({ operation, NEW }) => {
NEW.created_at = new Date().toISOString();
return true; // Allow operation
});
db.createTrigger('users', 'afterUpdate', ({ operation, OLD, NEW }) => {
console.log(`User ${OLD.name} updated to ${NEW.name}`);
});
```
## 🔄 Export/Import Workflow
### Export Data
```javascript
// Browser: Downloads file automatically
db.exportTable('users');
// Node.js: Get export string to save manually
const userData = db.getTableExport('users');
// fs.writeFileSync('./database/users.rdb', userData);
```
### Import Data
```javascript
// Load data from .rdb file content
const fileContent = fs.readFileSync('./database/users.rdb', 'utf8');
db.importTable('users', fileContent);
```
## 🌐 Browser Usage
```html
```
## 🔒 Manual Encryption Example
Users handle encryption before storing sensitive data:
```javascript
// Simple encryption functions (use proper crypto libraries in production)
function encrypt(data, key) {
return Buffer.from(JSON.stringify(data)).toString('base64');
}
function decrypt(encryptedData, key) {
return JSON.parse(Buffer.from(encryptedData, 'base64').toString('utf8'));
}
// Encrypt before storing
const sensitiveData = { password: 'secret123', apiKey: 'key-456' };
db.insert('secrets', {
id: 1,
data: encrypt(sensitiveData, 'my-key'),
type: 'credentials'
});
// Decrypt when retrieving
const record = db.where('id', 1).getOne('secrets');
const decryptedData = decrypt(record.data, 'my-key');
```
## 🛠️ Configuration Options
```javascript
const db = new RockdexDB({
// Storage Configuration
storageMode: 'file', // 'memory' or 'file'
storagePath: './data', // Database folder path
storageTable: [ // Manual table files
'users.rdb',
'posts.rdb',
'orders.rdb'
],
// Performance Optimizations
performance: true, // Enable performance optimizations
autoIndex: true, // Auto-create indexes based on schema
chunkSize: 10000, // Records per memory chunk (default: 10K)
maxMemoryChunks: 5, // Max chunks in RAM (default: 5)
compression: true, // Enable data compression
// Basic Configuration
logging: true, // Enable operation logging
timestamps: true, // Auto-add created_at/updated_at
softDelete: false, // Use soft deletes (deleted_at)
defaultData: { // Initial data for memory mode
users: [{ name: 'Admin', role: 'admin' }]
}
});
```
## 📊 Storage Statistics
```javascript
const stats = db.getStorageStats();
console.log(stats);
// {
// storageMode: 'file',
// storagePath: './database',
// storageTable: ['users.rdb', 'posts.rdb'],
// tables: {
// users: { totalRecords: 10, activeRecords: 8, deletedRecords: 2 }
// },
// totalRecords: 15,
// memoryUsage: 2.1 // MB
// }
```
## 🌟 Real-World Examples
### E-commerce Product Catalog
```javascript
const db = new RockdexDB({ storageMode: 'memory' });
// Create products table with schema
const productSchema = {
name: { type: 'string', required: true },
price: { type: 'number', required: true, min: 0 },
category: { type: 'string', required: true },
inStock: { type: 'boolean', required: false }
};
db.createTable('products', productSchema);
// Add sample products
db.bulkInsert('products', [
{ name: 'Laptop Pro', price: 1299, category: 'Electronics', inStock: true },
{ name: 'Coffee Mug', price: 15, category: 'Kitchen', inStock: true },
{ name: 'Running Shoes', price: 89, category: 'Sports', inStock: false }
]);
// Find affordable products in stock
const affordableProducts = db
.whereOperator('price', '<', 100)
.where('inStock', true)
.orderBy('price', 'ASC')
.get('products');
```
### User Management with Sessions
```javascript
const db = new RockdexDB({
storageMode: 'file',
storagePath: './userdata',
storageTable: ['users.rdb', 'sessions.rdb'],
timestamps: true
});
await db.ready();
// Create tables
db.createTable('users');
db.createTable('sessions');
// Add trigger for automatic session creation
db.createTrigger('users', 'afterInsert', ({ NEW }) => {
db.insert('sessions', {
userId: NEW.id,
token: 'session_' + Math.random().toString(36),
expiresAt: Date.now() + (24 * 60 * 60 * 1000) // 24 hours
});
return true;
});
// Register new user (automatically creates session)
db.insert('users', {
username: 'john_doe',
email: 'john@example.com',
role: 'user'
});
```
