throw new Error('Username already exists');
|
||||
}
|

|
||||
console.log(`User ${this.username} logged in. Login count: ${this.loginCount}`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Error Handling Examples
|
||||
|
||||
### Handling Creation Errors
|
||||
|
||||
```typescript
|
||||
async function createUserWithErrorHandling() {
|
||||
try {
|
||||
const user = await User.create({
|
||||
username: 'test_user',
|
||||
email: 'test@example.com'
|
||||
});
|
||||
|
||||
console.log('User created successfully:', user.id);
|
||||
return user;
|
||||
} catch (error) {
|
||||
if (error.message.includes('validation')) {
|
||||
console.error('Validation error:', error.message);
|
||||
} else if (error.message.includes('unique')) {
|
||||
console.error('Duplicate user:', error.message);
|
||||
} else {
|
||||
console.error('Unexpected error:', error.message);
|
||||
}
|
||||
|
||||
return null;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Handling Database Errors
|
||||
|
||||
```typescript
|
||||
async function robustUserCreation(userData: any) {
|
||||
let attempts = 0;
|
||||
const maxAttempts = 3;
|
||||
|
||||
while (attempts < maxAttempts) {
|
||||
try {
|
||||
const user = await User.create(userData);
|
||||
console.log(`User created on attempt ${attempts + 1}`);
|
||||
return user;
|
||||
} catch (error) {
|
||||
attempts++;
|
||||
console.error(`Attempt ${attempts} failed:`, error.message);
|
||||
|
||||
if (attempts >= maxAttempts) {
|
||||
console.error('Max attempts reached, giving up');
|
||||
throw error;
|
||||
}
|
||||
|
||||
// Wait before retrying
|
||||
await new Promise(resolve => setTimeout(resolve, 1000 * attempts));
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|

```
|
||||
|
||||
## Testing Your Implementation
|
||||
|
||||
### Basic Test
|
||||
|
||||
```typescript
|
||||
async function testBasicOperations() {
|
||||
console.log('🧪 Testing basic operations...');
|
||||
|
||||
try {
|
||||
// Test user creation
|
||||
const user = await User.create({
|
||||
username: 'testuser',
|
||||
email: 'test@example.com',
|
||||
});
|
||||
console.log('✅ User creation works');
|
||||
|
||||
// Test user retrieval
|
||||
const foundUser = await User.findById(user.id);
|
||||
console.log('✅ User retrieval works');
|
||||
|
||||
// Test user update
|
||||
foundUser.score = 100;
|
||||
await foundUser.save();
|
||||
console.log('✅ User update works');
|
||||
|
||||
// Test user deletion
|
||||
await foundUser.delete();
|
||||
console.log('✅ User deletion works');
|
||||
|
||||
console.log('🎉 All basic operations working!');
|
||||
} catch (error) {
|
||||
console.error('❌ Test failed:', error);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
These examples are based on the actual implementation and should work with the current version of DebrosFramework. Remember that advanced query features are still in development, so stick to the basic patterns shown here for now.

# Migration Guide
|
||||
|
||||
This guide helps you migrate between versions of DebrosFramework and understand breaking changes, new features, and upgrade procedures.
|
||||
|
||||

|
||||
- Advanced caching strategies
|
||||
- Performance monitoring tools
|
||||
- Distributed consensus features
|
||||
|
||||
## Upgrade Procedures
|
||||
|
||||
### From 0.4.x to 0.5.x
|
||||
|
||||
#### Breaking Changes
|
||||
|
||||
1. **Model Field Definition Changes**
|
||||
```typescript
|
||||
// OLD (0.4.x)
|
||||
@Field({ type: String, required: true })
|
||||
username: string;
|
||||
|
||||
// NEW (0.5.x)
|
||||
@Field({ type: 'string', required: true })
|
||||
username: string;
|
||||
```
|
||||
|
||||
2. **Framework Configuration Structure**
|
||||
```typescript
|
||||
// OLD (0.4.x)
|
||||
const framework = new DebrosFramework({
|
||||
cacheEnabled: true,
|
||||
logLevel: 'debug'
|
||||
});
|
||||
|
||||
// NEW (0.5.x)
|
||||
const framework = new DebrosFramework({
|
||||
features: {
|
||||
queryCache: true,
|
||||
},
|
||||
monitoring: {
|
||||
logLevel: 'debug'
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
3. **Query Builder API Changes**
|
||||
```typescript
|
||||
// OLD (0.4.x) - Static methods
|
||||
const users = await User.where('isActive', true).find();
|
||||
|
||||
// NEW (0.5.x) - Query builder pattern
|
||||
const users = await User.query().where('isActive', true).find();
|
||||
```
|
||||
|
||||
#### Migration Steps
|
||||
|
||||
1. **Update Package**
|
||||
```bash
|
||||
npm install @debros/network@^0.5.0
|
||||
```
|
||||
|
||||
2. **Update Field Definitions**
|
||||
```typescript
|
||||
// Update all field type definitions from constructors to strings
|
||||
@Field({ type: 'string' }) // instead of String
|
||||
@Field({ type: 'number' }) // instead of Number
|
||||
@Field({ type: 'boolean' }) // instead of Boolean
|
||||
@Field({ type: 'array' }) // instead of Array
|
||||
@Field({ type: 'object' }) // instead of Object
|
||||
```
|
||||
|
||||
3. **Update Framework Configuration**
|
||||
```typescript
|
||||
// Migrate old config structure to new nested structure
|
||||
const framework = new DebrosFramework({
|
||||
features: {
|
||||
queryCache: true,
|
||||
automaticPinning: true,
|
||||
pubsub: true,
|
||||
relationshipCache: true,
|
||||
},
|
||||
performance: {
|
||||
queryTimeout: 30000,
|
||||
batchSize: 100,
|
||||
},
|
||||
monitoring: {
|
||||
enableMetrics: true,
|
||||
logLevel: 'info',
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
4. **Update Query Patterns**
|
||||
```typescript
|
||||
// Replace static query methods with query builder
|
||||
|
||||
// OLD
|
||||
const users = await User.where('isActive', true).find();
|
||||
const posts = await Post.orderBy('createdAt', 'desc').limit(10).find();
|
||||
|
||||
// NEW
|
||||
const users = await User.query().where('isActive', true).find();
|
||||
const posts = await Post.query().orderBy('createdAt', 'desc').limit(10).find();
|
||||
```
|
||||
|
||||
5. **Update Error Handling**
|
||||
```typescript
|
||||
// NEW error types
|
||||
try {
|
||||
const user = await User.create(data);
|
||||
} catch (error) {
|
||||
if (error instanceof ValidationError) {
|
||||
console.log('Field validation failed:', error.field);
|
||||
} else if (error instanceof DatabaseError) {
|
||||
console.log('Database operation failed:', error.message);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Automated Migration Script
|
||||
|
||||
```typescript
|
||||

const testFramework = new DebrosFramework({
|
||||
environment: 'test',
|
||||
features: {
|
||||
queryCache: false, // Disable caching for testing
|
||||
},
|
||||
monitoring: {
|
||||
logLevel: 'debug', // Verbose logging
|
||||
},
|
||||
});
|
||||
|
||||
// Test all your models and operations
|
||||
async function testMigration() {
|
||||
try {
|
||||
await testFramework.initialize(orbitDBService, ipfsService);
|
||||
|
||||
// Test each model
|
||||
await testUserOperations();
|
||||
await testPostOperations();
|
||||
await testQueryOperations();
|
||||
|
||||
console.log('✅ Migration test passed');
|
||||
} catch (error) {
|
||||
console.error('❌ Migration test failed:', error);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Gradual Migration Strategy
|
||||
|
||||
```typescript
|
||||
// Step 1: Update dependencies
|
||||
// Step 2: Migrate models one at a time
|
||||
// Step 3: Update query patterns
|
||||
// Step 4: Test thoroughly
|
||||
// Step 5: Deploy to staging
|
||||
// Step 6: Deploy to production
|
||||
|
||||
class GradualMigration {
|
||||
private migratedModels = new Set<string>();
|
||||
|
||||
async migrateModel(modelName: string, modelClass: any) {
|
||||
try {
|
||||
// Validate model configuration
|
||||
await this.validateModelConfig(modelClass);
|
||||
|
||||
// Test basic operations
|
||||
await this.testModelOperations(modelClass);
|
||||
|
||||
this.migratedModels.add(modelName);
|
||||
console.log(`✅ Migrated model: ${modelName}`);
|
||||
} catch (error) {
|
||||
console.error(`❌ Failed to migrate model ${modelName}:`, error);
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
private async validateModelConfig(modelClass: any) {
|
||||
// Validate field definitions
|
||||
// Check relationship configurations
|
||||
// Verify decorator usage
|
||||
}
|
||||
|
||||
private async testModelOperations(modelClass: any) {
|
||||
// Test create, read, update, delete
|
||||
// Test query operations
|
||||
// Test relationships
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Backup and Recovery
|
||||
|
||||
```typescript
|
||||
// Create backup before migration
|
||||
async function createBackup() {
|
||||
const framework = getCurrentFramework();
|
||||
const databaseManager = framework.getDatabaseManager();
|
||||
|
||||
// Export all data
|
||||
const backup = {
|
||||
timestamp: Date.now(),
|
||||
version: '0.4.x',
|
||||
databases: {},
|
||||
};
|
||||
|
||||
// Backup each database
|
||||
const databases = await databaseManager.getAllDatabases();
|
||||
for (const [name, db] of databases) {
|
||||
backup.databases[name] = await exportDatabase(db);
|
||||
}
|
||||
|
||||
// Save backup
|
||||
await saveBackup(backup);
|
||||
console.log('✅ Backup created successfully');
|
||||
}
|
||||
|
||||
async function restoreFromBackup(backupPath: string) {
|
||||
const backup = await loadBackup(backupPath);
|
||||
|
||||
// Restore each database
|
||||
for (const [name, data] of Object.entries(backup.databases)) {
|
||||
await restoreDatabase(name, data);
|
||||
}
|
||||
|
||||
console.log('✅ Restored from backup');
|
||||
}
|
||||
```
|
||||
|
||||
## Troubleshooting Migration Issues
|
||||
|
||||
### Common Issues and Solutions
|
||||
|
||||
#### 1. Field Type Errors
|
||||
|
||||
**Problem**: `TypeError: Field type must be a string`
|
||||
|
||||
**Solution**:
|
||||
```typescript
|
||||
// Wrong
|
||||
@Field({ type: String })
|
||||
|
||||
// Correct
|
||||
@Field({ type: 'string' })
|
||||
```
|
||||
|
||||
#### 2. Query Builder Not Found
|
||||
|
||||
**Problem**: `TypeError: User.where is not a function`
|
||||
|
||||
**Solution**:
|
||||
```typescript
|
||||
// Wrong
|
||||
const users = await User.where('isActive', true).find();
|
||||
|
||||
// Correct
|
||||
const users = await User.query().where('isActive', true).find();
|
||||
```
|
||||
|
||||
#### 3. Configuration Structure Errors
|
||||
|
||||
**Problem**: `Unknown configuration option: cacheEnabled`
|
||||
|
||||
**Solution**:
|
||||
```typescript
|
||||
// Wrong
|
||||
const framework = new DebrosFramework({
|
||||
cacheEnabled: true
|
||||
});
|
||||
|
||||
// Correct
|
||||
const framework = new DebrosFramework({
|
||||
features: {
|
||||
queryCache: true
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
#### 4. Relationship Loading Issues
|
||||
|
||||
**Problem**: `Cannot read property 'posts' of undefined`
|
||||
|
||||
**Solution**:
|
||||
```typescript
|
||||
// Ensure relationships are loaded
|
||||
const user = await User.findById(userId, {
|
||||
with: ['posts']
|
||||
});
|
||||
|
||||
// Or use the relationship manager
|
||||
const relationshipManager = framework.getRelationshipManager();
|
||||
await relationshipManager.loadRelationship(user, 'posts');
|
||||
```
|
||||
|
||||
### Migration Validation
|
||||
|
||||
```typescript
|
||||
// Validation script to run after migration
|
||||
async function validateMigration() {
|
||||
const checks = [
|
||||
validateModels,
|
||||
validateQueries,
|
||||
validateRelationships,
|
||||
validatePerformance,
|
||||
];
|
||||
|
||||
for (const check of checks) {
|
||||
try {
|
||||
await check();
|
||||
console.log(`✅ ${check.name} passed`);
|
||||
} catch (error) {
|
||||
console.error(`❌ ${check.name} failed:`, error);
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
console.log('🎉 Migration validation completed successfully');
|
||||
}
|
||||
|
||||
async function validateModels() {
|
||||
// Test model creation, updates, deletion
|
||||
const user = await User.create({
|
||||
username: 'test_migration',
|
||||
email: 'test@migration.com'
|
||||
});
|
||||
|
||||
await user.delete();
|
||||
}
|
||||
|
||||
async function validateQueries() {
|
||||
// Test basic queries work
|
||||
const users = await User.query().find();
|
||||
if (!Array.isArray(users)) {
|
||||
throw new Error('Query did not return array');
|
||||
}
|
||||
}
|
||||
|
||||
async function validateRelationships() {
|
||||
// Test relationship loading
|
||||
// Implementation depends on your models
|
||||
}
|
||||
|
||||
async function validatePerformance() {
|
||||
// Basic performance checks
|
||||
const start = Date.now();
|
||||
await User.query().find();
|
||||
const duration = Date.now() - start;
|
||||
|
||||
if (duration > 5000) {
|
||||
console.warn('⚠️ Query performance degraded');
|
||||
}
|
||||
}
|
||||
```

# Behind the Scenes: How DebrosFramework Works with OrbitDB
|
||||
|
||||
This guide explains what happens under the hood when you use DebrosFramework's high-level abstractions. Understanding these internals will help you debug issues, optimize performance, and better understand the framework's architecture.
|
||||
|
||||
## Overview: From Models to OrbitDB
|
||||
|
||||
DebrosFramework provides ORM-like abstractions over OrbitDB's peer-to-peer databases. When you define models, create relationships, and run migrations, the framework translates these operations into OrbitDB database operations.
|
||||
|
||||
```
|
||||
Your Code → DebrosFramework → OrbitDB → IPFS
|
||||
```
|
||||
|
||||
## Model Creation and Database Mapping
|
||||
|
||||
### What Happens When You Define a Model
|
||||
|
||||
When you define a model like this:
|
||||
|
||||
```typescript
|
||||
@Model({
|
||||
scope: 'global',
|
||||
type: 'docstore',
|
||||
sharding: { strategy: 'hash', count: 4, key: 'id' }
|
||||
})
|
||||
export class User extends BaseModel {
|
||||
@Field({ type: 'string', required: true })
|
||||
username: string;
|
||||
|
||||
@Field({ type: 'string', required: true })
|
||||
email: string;
|
||||
}
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
1. **Model Registration**: The `@Model` decorator registers the model in `ModelRegistry`
|
||||
2. **Field Configuration**: `@Field` decorators are stored in a static `fields` Map on the model class
|
||||
3. **Database Planning**: The framework determines what OrbitDB databases need to be created
|
||||
|
||||
### OrbitDB Database Creation
|
||||
|
||||
For the `User` model above, DebrosFramework creates:
|
||||
|
||||
```typescript
|
||||
// Global scope, no sharding
|
||||
const userDB = await orbitdb.open('global-user', 'docstore', {
|
||||
accessController: {
|
||||
type: 'orbitdb',
|
||||
write: ['*'] // Or specific access rules
|
||||
}
|
||||
});
|
||||
|
||||
// With sharding (strategy: 'hash', count: 4)
|
||||
const userShard0 = await orbitdb.open('global-user-shard-0', 'docstore');
|
||||
const userShard1 = await orbitdb.open('global-user-shard-1', 'docstore');
|
||||
const userShard2 = await orbitdb.open('global-user-shard-2', 'docstore');
|
||||
const userShard3 = await orbitdb.open('global-user-shard-3', 'docstore');
|
||||
```
|
||||
|
||||
### Database Naming Convention
|
||||
|
||||
```typescript
|
||||
// Global models
|
||||
`global-${modelName.toLowerCase()}`
|
||||
|
||||
// User-scoped models
|
||||
`${userId}-${modelName.toLowerCase()}`
|
||||
|
||||
// Sharded models
|
||||
`${scope}-${modelName.toLowerCase()}-shard-${shardIndex}`
|
||||
|
||||
// System databases
|
||||
`${appName}-bootstrap` // Shard coordination
|
||||
`${appName}-directory-shard-${i}` // User directory
|
||||
`${userId}-mappings` // User's database mappings
|
||||
```
|
||||
|
||||
## CRUD Operations Under the Hood
|
||||
|
||||
### Creating a Record
|
||||
|
||||
When you call:
|
||||
|
||||
```typescript
|
||||
const user = await User.create({
|
||||
username: 'alice',
|
||||
email: 'alice@example.com'
|
||||
});
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
1. **Validation**: Field validators run on the data
|
||||
2. **Transformation**: Field transformers process the data
|
||||
3. **ID Generation**: A unique ID is generated (typically UUID)
|
||||
4. **Lifecycle Hooks**: `@BeforeCreate` hooks execute
|
||||
5. **Shard Selection**: If sharded, determine which shard to use
|
||||
6. **OrbitDB Operation**: Data is stored in the appropriate database
|
||||
|
||||
```typescript
|
||||
// What actually happens in OrbitDB
|
||||
const database = await this.getShardForKey(user.id); // or getGlobalDatabase()
|
||||
const docHash = await database.put({
|
||||
_id: user.id,
|
||||
username: 'alice',
|
||||
email: 'alice@example.com',
|
||||
_model: 'User',
|
||||
_createdAt: Date.now(),
|
||||
_updatedAt: Date.now()
|
||||
});
|
||||
```
|
||||
|
||||
### Reading Records
|
||||
|
||||
When you call:
|
||||
|
||||
```typescript
|
||||
const user = await User.findById('user123');
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
1. **Shard Resolution**: Determine which shard contains the record
|
||||
2. **Database Query**: Query the appropriate OrbitDB database
|
||||
3. **Data Hydration**: Convert raw OrbitDB data back to model instance
|
||||
4. **Field Processing**: Apply any field transformations
|
||||
|
||||
```typescript
|
||||
// OrbitDB operations
|
||||
const shard = this.getShardForKey('user123');
|
||||
const doc = await shard.get('user123');
|
||||
|
||||
if (doc) {
|
||||
// Convert to model instance
|
||||
const user = new User(doc);
|
||||
user._isNew = false;
|
||||
return user;
|
||||
}
|
||||
```
|
||||
|
||||
### Query Operations
|
||||
|
||||
When you call:
|
||||
|
||||
```typescript
|
||||
const users = await User.query().where('isActive', true).find();
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
1. **Query Planning**: Determine which databases to search
|
||||
2. **Parallel Queries**: Query all relevant shards simultaneously
|
||||
3. **Result Aggregation**: Combine results from multiple databases
|
||||
4. **Filtering**: Apply where conditions to the aggregated results
|
||||
|
||||
```typescript
|
||||
// Actual implementation
|
||||
const shards = this.getAllShardsForModel('User');
|
||||
const results = await Promise.all(
|
||||
shards.map(async (shard) => {
|
||||
const docs = shard.iterator().collect();
|
||||
return docs.filter(doc => doc.isActive === true);
|
||||
})
|
||||
);
|
||||
|
||||
const allResults = results.flat();
|
||||
return allResults.map(doc => new User(doc));
|
||||
```
|
||||
|
||||
## Relationships and Cross-Database Operations
|
||||
|
||||
### How Relationships Work
|
||||
|
||||
When you define relationships:
|
||||
|
||||
```typescript
|
||||
@Model({ scope: 'global', type: 'docstore' })
|
||||
export class User extends BaseModel {
|
||||
@HasMany(() => Post, 'authorId')
|
||||
posts: Post[];
|
||||
}
|
||||
|
||||
@Model({ scope: 'user', type: 'docstore' })
|
||||
export class Post extends BaseModel {
|
||||
@Field({ type: 'string', required: true })
|
||||
authorId: string;
|
||||
|
||||
@BelongsTo(() => User, 'authorId')
|
||||
author: User;
|
||||
}
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
Relationships are stored as foreign keys and resolved through cross-database queries:
|
||||
|
||||
```typescript
|
||||
// User in global database
|
||||
{
|
||||
_id: 'user123',
|
||||
username: 'alice',
|
||||
_model: 'User'
|
||||
}
|
||||
|
||||
// Posts in user-specific database
|
||||
{
|
||||
_id: 'post456',
|
||||
title: 'My Post',
|
||||
authorId: 'user123', // Foreign key reference
|
||||
_model: 'Post'
|
||||
}
|
||||
```
|
||||
|
||||
### Relationship Loading
|
||||
|
||||
When you load relationships:
|
||||
|
||||
```typescript
|
||||
const user = await User.findById('user123', { with: ['posts'] });
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
1. **Primary Query**: Load the user from global database
|
||||
2. **Relationship Resolution**: Identify related models and their databases
|
||||
3. **Cross-Database Query**: Query user-specific databases for posts
|
||||
4. **Data Assembly**: Attach loaded relationships to the main model
|
||||
|
||||
```typescript
|
||||
// Implementation
|
||||
const user = await globalUserDB.get('user123');
|
||||
const userDB = await this.getUserDatabase('user123', 'Post');
|
||||
const posts = await userDB.iterator().collect()
|
||||
.filter(doc => doc.authorId === 'user123');
|
||||
|
||||
user.posts = posts.map(doc => new Post(doc));
|
||||
```
|
||||
|
||||
## Sharding Implementation
|
||||
|
||||
### Hash Sharding
|
||||
|
||||
When you configure hash sharding:
|
||||
|
||||
```typescript
|
||||
@Model({
|
||||
sharding: { strategy: 'hash', count: 4, key: 'id' }
|
||||
})
|
||||
export class Post extends BaseModel {
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
```typescript
|
||||
// Shard selection algorithm
|
||||
function getShardForKey(key: string, shardCount: number): number {
|
||||
const hash = crypto.createHash('sha256').update(key).digest('hex');
|
||||
const hashInt = parseInt(hash.substring(0, 8), 16);
|
||||
return hashInt % shardCount;
|
||||
}
|
||||
|
||||
// Creating a post
|
||||
const post = new Post({ title: 'Hello' });
|
||||
const shardIndex = getShardForKey(post.id, 4); // Returns 0-3
|
||||
const database = await orbitdb.open(`user123-post-shard-${shardIndex}`, 'docstore');
|
||||
await database.put(post.toJSON());
|
||||
```
|
||||
|
||||
### User Sharding
|
||||
|
||||
For user-scoped models:
|
||||
|
||||
```typescript
|
||||
@Model({
|
||||
scope: 'user',
|
||||
sharding: { strategy: 'user', count: 2, key: 'authorId' }
|
||||
})
|
||||
export class Post extends BaseModel {
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
```typescript
|
||||
// Each user gets their own set of sharded databases
|
||||
const userId = 'user123';
|
||||
const shardIndex = getShardForKey(post.id, 2);
|
||||
const database = await orbitdb.open(`${userId}-post-shard-${shardIndex}`, 'docstore');
|
||||
```
|
||||
|
||||
## Migration System Implementation
|
||||
|
||||
### What Migrations Actually Do
|
||||
|
||||
Since OrbitDB doesn't have traditional schema migrations, DebrosFramework implements them differently:
|
||||
|
||||
```typescript
|
||||
const migration = createMigration('add_user_bio', '1.1.0')
|
||||
.addField('User', 'bio', { type: 'string', required: false })
|
||||
.transformData('User', (user) => ({
|
||||
...user,
|
||||
bio: user.bio || 'No bio provided'
|
||||
}))
|
||||
.build();
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
1. **Migration Tracking**: Store migration state in a special database
|
||||
2. **Data Transformation**: Read all records, transform them, and write back
|
||||
3. **Schema Updates**: Update model field configurations
|
||||
4. **Validation**: Ensure all data conforms to new schema
|
||||
|
||||
```typescript
|
||||
// Migration implementation
|
||||
async function runMigration(migration: Migration) {
|
||||
// Track migration state
|
||||
const migrationDB = await orbitdb.open('migrations', 'docstore');
|
||||
|
||||
// For each target model
|
||||
for (const modelName of migration.targetModels) {
|
||||
const databases = await this.getAllDatabasesForModel(modelName);
|
||||
|
||||
for (const database of databases) {
|
||||
// Read all documents
|
||||
const docs = await database.iterator().collect();
|
||||
|
||||
// Transform each document
|
||||
for (const doc of docs) {
|
||||
const transformed = migration.transform(doc);
|
||||
await database.put(transformed);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// Record migration as completed
|
||||
await migrationDB.put({
|
||||
_id: migration.id,
|
||||
version: migration.version,
|
||||
appliedAt: Date.now(),
|
||||
status: 'completed'
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
## User Directory and Database Discovery
|
||||
|
||||
### How User Databases Are Discovered
|
||||
|
||||
DebrosFramework maintains a distributed directory system:
|
||||
|
||||
```typescript
|
||||
// Bootstrap database (shared across network)
|
||||
const bootstrap = await orbitdb.open('myapp-bootstrap', 'keyvalue');
|
||||
|
||||
// Directory shards for user mappings
|
||||
const dirShard0 = await orbitdb.open('myapp-directory-shard-0', 'keyvalue');
|
||||
const dirShard1 = await orbitdb.open('myapp-directory-shard-1', 'keyvalue');
|
||||
const dirShard2 = await orbitdb.open('myapp-directory-shard-2', 'keyvalue');
|
||||
const dirShard3 = await orbitdb.open('myapp-directory-shard-3', 'keyvalue');
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
When a user creates their first record:
|
||||
|
||||
1. **User Database Creation**: Create user-specific databases
|
||||
2. **Mapping Storage**: Store database addresses in user's mappings database
|
||||
3. **Directory Registration**: Register user's mappings database in global directory
|
||||
4. **Shard Distribution**: Use consistent hashing to distribute users across directory shards
|
||||
|
||||
```typescript
|
||||
// Creating user databases
|
||||
async function createUserDatabases(userId: string) {
|
||||
// Create mappings database
|
||||
const mappingsDB = await orbitdb.open(`${userId}-mappings`, 'keyvalue');
|
||||
|
||||
// Create model databases
|
||||
const postDB = await orbitdb.open(`${userId}-post`, 'docstore');
|
||||
const commentDB = await orbitdb.open(`${userId}-comment`, 'docstore');
|
||||
|
||||
// Store mappings
|
||||
await mappingsDB.set('mappings', {
|
||||
postDB: postDB.address.toString(),
|
||||
commentDB: commentDB.address.toString()
|
||||
});
|
||||
|
||||
// Register in global directory
|
||||
const dirShard = this.getDirectoryShardForUser(userId);
|
||||
await dirShard.set(userId, mappingsDB.address.toString());
|
||||
|
||||
return { mappingsDB, postDB, commentDB };
|
||||
}
|
||||
```
|
||||
|
||||
## Caching and Performance Optimization
|
||||
|
||||
### Query Caching
|
||||
|
||||
When you enable query caching:
|
||||
|
||||
```typescript
|
||||
const framework = new DebrosFramework({
|
||||
features: { queryCache: true }
|
||||
});
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
```typescript
|
||||
// Cache key generation
|
||||
function generateCacheKey(query: QueryBuilder): string {
|
||||
return crypto
|
||||
.createHash('md5')
|
||||
.update(JSON.stringify({
|
||||
model: query.modelName,
|
||||
where: query.whereConditions,
|
||||
orderBy: query.orderByConditions,
|
||||
limit: query.limitValue
|
||||
}))
|
||||
.digest('hex');
|
||||
}
|
||||
|
||||
// Query execution with caching
|
||||
async function executeQuery(query: QueryBuilder) {
|
||||
const cacheKey = generateCacheKey(query);
|
||||
|
||||
// Check cache first
|
||||
const cached = await this.queryCache.get(cacheKey);
|
||||
if (cached) {
|
||||
return cached.map(data => new query.ModelClass(data));
|
||||
}
|
||||
|
||||
// Execute query
|
||||
const results = await this.executeQueryOnDatabases(query);
|
||||
|
||||
// Cache results
|
||||
await this.queryCache.set(cacheKey, results.map(r => r.toJSON()), 300000);
|
||||
|
||||
return results;
|
||||
}
|
||||
```
|
||||
|
||||
### Relationship Caching
|
||||
|
||||
```typescript
|
||||
// Relationship cache
|
||||
const relationshipCache = new Map();
|
||||
|
||||
async function loadRelationship(model: BaseModel, relationshipName: string) {
|
||||
const cacheKey = `${model.constructor.name}:${model.id}:${relationshipName}`;
|
||||
|
||||
if (relationshipCache.has(cacheKey)) {
|
||||
return relationshipCache.get(cacheKey);
|
||||
}
|
||||
|
||||
// Load relationship from databases
|
||||
const related = await this.queryRelatedModels(model, relationshipName);
|
||||
|
||||
// Cache for 5 minutes
|
||||
relationshipCache.set(cacheKey, related);
|
||||
setTimeout(() => relationshipCache.delete(cacheKey), 300000);
|
||||
|
||||
return related;
|
||||
}
|
||||
```
|
||||
|
||||
## Automatic Pinning Strategy
|
||||
|
||||
### How Pinning Works
|
||||
|
||||
When you enable automatic pinning:
|
||||
|
||||
```typescript
|
||||
const framework = new DebrosFramework({
|
||||
features: { automaticPinning: true }
|
||||
});
|
||||
```
|
||||
|
||||
**Behind the scenes:**
|
||||
|
||||
```typescript
|
||||
// Pinning manager tracks access patterns
|
||||
class PinningManager {
|
||||
private accessCount = new Map<string, number>();
|
||||
private pinned = new Set<string>();
|
||||
|
||||
async trackAccess(address: string) {
|
||||
const count = this.accessCount.get(address) || 0;
|
||||
this.accessCount.set(address, count + 1);
|
||||
|
||||
// Pin popular content
|
||||
if (count > 10 && !this.pinned.has(address)) {
|
||||
await this.ipfs.pin.add(address);
|
||||
this.pinned.add(address);
|
||||
console.log(`📌 Pinned popular content: ${address}`);
|
||||
}
|
||||
}
|
||||
|
||||
async evaluatePinning() {
|
||||
// Run every hour
|
||||
setInterval(() => {
|
||||
this.unpinStaleContent();
|
||||
this.pinPopularContent();
|
||||
}, 3600000);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## PubSub and Real-time Updates
|
||||
|
||||
### Event Publishing
|
||||
|
||||
When models change:
|
||||
|
||||
```typescript
|
||||
// After successful database operation
|
||||
async function publishModelEvent(event: ModelEvent) {
|
||||
const topic = `debros:${event.modelName}:${event.type}`;
|
||||
await this.pubsub.publish(topic, JSON.stringify(event));
|
||||
}
|
||||
|
||||
// Model creation
|
||||
await User.create({ username: 'alice' });
|
||||
// Publishes to: "debros:User:create"
|
||||
|
||||
// Model update
|
||||
await user.save();
|
||||
// Publishes to: "debros:User:update"
|
||||
```
|
||||
|
||||
### Event Subscription
|
||||
|
||||
```typescript
|
||||
// Subscribe to model events
|
||||
pubsub.subscribe('debros:User:*', (message) => {
|
||||
const event = JSON.parse(message);
|
||||
console.log(`User ${event.type}: ${event.modelId}`);
|
||||
|
||||
// Invalidate related caches
|
||||
this.invalidateUserCache(event.modelId);
|
||||
});
|
||||
```
|
||||
|
||||
## Database Synchronization
|
||||
|
||||
### How Peers Sync Data
|
||||
|
||||
OrbitDB handles the low-level synchronization, but DebrosFramework optimizes it:
|
||||
|
||||
```typescript
|
||||
// Replication configuration
|
||||
const database = await orbitdb.open('global-user', 'docstore', {
|
||||
replicate: true,
|
||||
sync: true,
|
||||
accessController: {
|
||||
type: 'orbitdb',
|
||||
write: ['*']
|
||||
}
|
||||
});
|
||||
|
||||
// Custom sync logic
|
||||
database.events.on('peer', (peer) => {
|
||||
console.log(`👥 Peer connected: ${peer}`);
|
||||
});
|
||||
|
||||
database.events.on('replicated', (address) => {
|
||||
console.log(`🔄 Replicated data from: ${address}`);
|
||||
// Invalidate caches, trigger UI updates
|
||||
this.invalidateCaches();
|
||||
});
|
||||
```
|
||||
|
||||
## Error Handling and Recovery
|
||||
|
||||
### Database Connection Failures
|
||||
|
||||
```typescript
|
||||
// Retry logic for database operations
|
||||
async function withRetry<T>(operation: () => Promise<T>, maxRetries = 3): Promise<T> {
|
||||
for (let attempt = 1; attempt <= maxRetries; attempt++) {
|
||||
try {
|
||||
return await operation();
|
||||
} catch (error) {
|
||||
if (attempt === maxRetries) throw error;
|
||||
|
||||
const delay = Math.pow(2, attempt) * 1000; // Exponential backoff
|
||||
await new Promise(resolve => setTimeout(resolve, delay));
|
||||
}
|
||||
}
|
||||
throw new Error('Max retries exceeded');
|
||||
}
|
||||
|
||||
// Usage
|
||||
const user = await withRetry(() => User.findById('user123'));
|
||||
```
|
||||
|
||||
### Data Corruption Recovery
|
||||
|
||||
```typescript
|
||||
// Validate data integrity
|
||||
async function validateDatabase(database: Database) {
|
||||
const docs = await database.iterator().collect();
|
||||
|
||||
for (const doc of docs) {
|
||||
try {
|
||||
// Validate against model schema
|
||||
const model = new modelClass(doc);
|
||||
await model.validate();
|
||||
} catch (error) {
|
||||
console.warn(`⚠️ Invalid document found: ${doc._id}`, error);
|
||||
// Mark for repair or removal
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Monitoring
|
||||
|
||||
### Internal Metrics
|
||||
|
||||
```typescript
|
||||
// Performance tracking
|
||||
class MetricsCollector {
|
||||
private queryTimes = new Map<string, number[]>();
|
||||
private operationCounts = new Map<string, number>();
|
||||
|
||||
recordQueryTime(operation: string, duration: number) {
|
||||
const times = this.queryTimes.get(operation) || [];
|
||||
times.push(duration);
|
||||
this.queryTimes.set(operation, times.slice(-100)); // Keep last 100
|
||||
}
|
||||
|
||||
getAverageQueryTime(operation: string): number {
|
||||
const times = this.queryTimes.get(operation) || [];
|
||||
return times.reduce((a, b) => a + b, 0) / times.length;
|
||||
}
|
||||
|
||||
getMetrics() {
|
||||
return {
|
||||
queryTimes: Object.fromEntries(this.queryTimes),
|
||||
operationCounts: Object.fromEntries(this.operationCounts),
|
||||
cacheHitRates: this.getCacheHitRates(),
|
||||
databaseSizes: this.getDatabaseSizes()
|
||||
};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Debugging and Introspection
|
||||
|
||||
### Debug Mode
|
||||
|
||||
```typescript
|
||||
const framework = new DebrosFramework({
|
||||
monitoring: { logLevel: 'debug' }
|
||||
});
|
||||
|
||||
// Enables detailed logging
|
||||
// 🔍 Query: User.findById(user123) -> shard-2
|
||||
// 📊 Cache miss: query-hash-abc123
|
||||
// 🔄 Database operation: put user123 -> completed in 45ms
|
||||
// 📡 PubSub: published User:create event
|
||||
```
|
||||
|
||||
### Database Inspection
|
||||
|
||||
```typescript
|
||||
// Access raw OrbitDB databases for debugging
|
||||
const framework = getFramework();
|
||||
const databaseManager = framework.getDatabaseManager();
|
||||
|
||||
// List all databases
|
||||
const databases = await databaseManager.getAllDatabases();
|
||||
console.log('Databases:', Array.from(databases.keys()));
|
||||
|
||||
// Inspect database contents
|
||||
const userDB = await databaseManager.getGlobalDatabase('User');
|
||||
const docs = await userDB.iterator().collect();
|
||||
console.log('User documents:', docs);
|
||||
|
||||
// Check database addresses
|
||||
console.log('Database address:', userDB.address.toString());
|
||||
```
|
||||
|
||||
