|
||||
### Search Functionality
|
||||
SmartData provides powerful search capabilities with a Lucene-like query syntax and robust fallback mechanisms:
|
||||
|
||||
For more details on usage and additional features, refer to the [official documentation](https://gitlab.com/push.rocks/smartdata#README) and explore the various classes and methods provided by `@push.rocks/smartdata`.
|
||||
```typescript
|
||||
// Define a model with searchable fields
|
||||
@Collection(() => db)
|
||||
class Product extends SmartDataDbDoc<Product, Product> {
|
||||
@unI()
|
||||
public id: string = 'product-id';
|
||||
|
||||
@svDb()
|
||||
@searchable() // Mark this field as searchable
|
||||
public name: string;
|
||||
|
||||
@svDb()
|
||||
@searchable() // Mark this field as searchable
|
||||
public description: string;
|
||||
|
||||
@svDb()
|
||||
@searchable() // Mark this field as searchable
|
||||
public category: string;
|
||||
|
||||
@svDb()
|
||||
public price: number;
|
||||
}
|
||||
|
||||
// Get all fields marked as searchable for a class
|
||||
const searchableFields = getSearchableFields('Product'); // ['name', 'description', 'category']
|
||||
|
||||
// Basic search across all searchable fields
|
||||
const iPhoneProducts = await Product.searchWithLucene('iPhone');
|
||||
|
||||
// Field-specific search
|
||||
const electronicsProducts = await Product.searchWithLucene('category:Electronics');
|
||||
|
||||
// Search with wildcards
|
||||
const macProducts = await Product.searchWithLucene('Mac*');
|
||||
|
||||
// Search in specific fields with partial words
|
||||
const laptopResults = await Product.searchWithLucene('description:laptop');
|
||||
|
||||
// Search is case-insensitive
|
||||
const results1 = await Product.searchWithLucene('electronics');
|
||||
const results2 = await Product.searchWithLucene('Electronics');
|
||||
// results1 and results2 will contain the same documents
|
||||
|
||||
// Using boolean operators (requires text index in MongoDB)
|
||||
const wirelessOrLaptop = await Product.searchWithLucene('wireless OR laptop');
|
||||
|
||||
// Negative searches
|
||||
const electronicsNotSamsung = await Product.searchWithLucene('Electronics NOT Samsung');
|
||||
|
||||
// Phrase searches
|
||||
const exactPhrase = await Product.searchWithLucene('"high-speed blender"');
|
||||
|
||||
// Grouping with parentheses
|
||||
const complexQuery = await Product.searchWithLucene('(wireless OR bluetooth) AND Electronics');
|
||||
```
|
||||
|
||||
The search functionality includes:
|
||||
- `@searchable()` decorator for marking fields as searchable
|
||||
- `getSearchableFields()` to retrieve all searchable fields for a class
|
||||
- `search()` method for basic search (requires MongoDB text index)
|
||||
- `searchWithLucene()` method with robust fallback mechanisms
|
||||
- Support for field-specific searches, wildcards, and boolean operators
|
||||
- Automatic fallback to regex-based search if MongoDB text search fails
|
||||
|
||||
### EasyStore
|
||||
EasyStore provides a simple key-value storage system with automatic persistence:
|
||||
|
||||
```typescript
|
||||
// Create an EasyStore instance with a specific type
|
||||
interface ConfigStore {
|
||||
apiKey: string;
|
||||
settings: {
|
||||
theme: string;
|
||||
notifications: boolean;
|
||||
};
|
||||
}
|
||||
|
||||
// Create a type-safe EasyStore
|
||||
const store = await db.createEasyStore<ConfigStore>('app-config');
|
||||
|
||||
// Write and read data with full type safety
|
||||
await store.writeKey('apiKey', 'secret-api-key-123');
|
||||
await store.writeKey('settings', { theme: 'dark', notifications: true });
|
||||
|
||||
const apiKey = await store.readKey('apiKey'); // Type: string
|
||||
const settings = await store.readKey('settings'); // Type: { theme: string, notifications: boolean }
|
||||
|
||||
// Check if a key exists
|
||||
const hasKey = await store.hasKey('apiKey'); // true
|
||||
|
||||
// Delete a key
|
||||
await store.deleteKey('apiKey');
|
||||
```
|
||||
|
||||
### Distributed Coordination
|
||||
Built-in support for distributed systems with leader election:
|
||||
|
||||
```typescript
|
||||
// Create a distributed coordinator
|
||||
const coordinator = new SmartdataDistributedCoordinator(db);
|
||||
|
||||
// Start coordination
|
||||
await coordinator.start();
|
||||
|
||||
// Handle leadership changes
|
||||
coordinator.on('leadershipChange', (isLeader) => {
|
||||
if (isLeader) {
|
||||
// This instance is now the leader
|
||||
// Run leader-specific tasks
|
||||
startPeriodicJobs();
|
||||
} else {
|
||||
// This instance is no longer the leader
|
||||
stopPeriodicJobs();
|
||||
}
|
||||
});
|
||||
|
||||
// Access leadership status anytime
|
||||
if (coordinator.isLeader) {
|
||||
// Run leader-only operations
|
||||
}
|
||||
|
||||
// Execute a task only on the leader
|
||||
await coordinator.executeIfLeader(async () => {
|
||||
// This code only runs on the leader instance
|
||||
await runImportantTask();
|
||||
});
|
||||
|
||||
// Stop coordination when shutting down
|
||||
await coordinator.stop();
|
||||
```
|
||||
|
||||
### Real-time Data Watching
|
||||
Watch for changes in your collections with RxJS integration using MongoDB Change Streams:
|
||||
|
||||
```typescript
|
||||
// Create a watcher for a specific collection with a query filter
|
||||
const watcher = await User.watch({
|
||||
active: true // Only watch for changes to active users
|
||||
}, {
|
||||
fullDocument: true, // Include the full document in change notifications
|
||||
bufferTimeMs: 100 // Buffer changes for 100ms to reduce notification frequency
|
||||
});
|
||||
|
||||
// Subscribe to changes using RxJS
|
||||
watcher.changeSubject.subscribe((change) => {
|
||||
console.log('Change operation:', change.operationType); // 'insert', 'update', 'delete', etc.
|
||||
console.log('Document changed:', change.docInstance); // The full document instance
|
||||
|
||||
// Handle different types of changes
|
||||
if (change.operationType === 'insert') {
|
||||
console.log('New user created:', change.docInstance.username);
|
||||
} else if (change.operationType === 'update') {
|
||||
console.log('User updated:', change.docInstance.username);
|
||||
} else if (change.operationType === 'delete') {
|
||||
console.log('User deleted');
|
||||
}
|
||||
});
|
||||
|
||||
// Manual observation with event emitter pattern
|
||||
watcher.on('change', (change) => {
|
||||
console.log('Document changed:', change);
|
||||
});
|
||||
|
||||
// Stop watching when no longer needed
|
||||
await watcher.stop();
|
||||
```
|
||||
|
||||
### Managed Collections
|
||||
For more complex data models that require additional context:
|
||||
|
||||
```typescript
|
||||
@Collection(() => db)
|
||||
class ManagedDoc extends SmartDataDbDoc<ManagedDoc, ManagedDoc> {
|
||||
@unI()
|
||||
public id: string = 'unique-id';
|
||||
|
||||
@svDb()
|
||||
public data: string;
|
||||
|
||||
@managed()
|
||||
public manager: YourCustomManager;
|
||||
|
||||
// The manager can provide additional functionality
|
||||
async specialOperation() {
|
||||
return this.manager.doSomethingSpecial(this);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Automatic Indexing
|
||||
Define indexes directly in your model class:
|
||||
|
||||
```typescript
|
||||
@Collection(() => db)
|
||||
class Product extends SmartDataDbDoc<Product, Product> {
|
||||
@unI() // Unique index
|
||||
public id: string = 'product-id';
|
||||
|
||||
@svDb()
|
||||
@index() // Regular index for faster queries
|
||||
public category: string;
|
||||
|
||||
@svDb()
|
||||
@index({ sparse: true }) // Sparse index with options
|
||||
public optionalField?: string;
|
||||
|
||||
// Compound indexes can be defined in the collection decorator
|
||||
@Collection(() => db, {
|
||||
indexMap: {
|
||||
compoundIndex: {
|
||||
fields: { category: 1, name: 1 },
|
||||
options: { background: true }
|
||||
}
|
||||
}
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
### Transaction Support
|
||||
Use MongoDB transactions for atomic operations:
|
||||
|
||||
```typescript
|
||||
const session = await db.startSession();
|
||||
try {
|
||||
await session.withTransaction(async () => {
|
||||
const user = await User.getInstance({ id: 'user-id' }, { session });
|
||||
user.balance -= 100;
|
||||
await user.save({ session });
|
||||
|
||||
const recipient = await User.getInstance({ id: 'recipient-id' }, { session });
|
||||
recipient.balance += 100;
|
||||
await user.save({ session });
|
||||
});
|
||||
} finally {
|
||||
await session.endSession();
|
||||
}
|
||||
```
|
||||
|
||||
### Deep Object Queries
|
||||
SmartData provides fully type-safe deep property queries with the `DeepQuery` type:
|
||||
|
||||
```typescript
|
||||
// If your document has nested objects
|
||||
class UserProfile extends SmartDataDbDoc<UserProfile, UserProfile> {
|
||||
@unI()
|
||||
public id: string = 'profile-id';
|
||||
|
||||
@svDb()
|
||||
public user: {
|
||||
details: {
|
||||
firstName: string;
|
||||
lastName: string;
|
||||
address: {
|
||||
city: string;
|
||||
country: string;
|
||||
}
|
||||
}
|
||||
};
|
||||
}
|
||||
|
||||
// Type-safe string literals for dot notation
|
||||
const usersInUSA = await UserProfile.getInstances({
|
||||
'user.details.address.country': 'USA'
|
||||
});
|
||||
|
||||
// Fully typed deep queries with the DeepQuery type
|
||||
import { DeepQuery } from '@push.rocks/smartdata';
|
||||
|
||||
const typedQuery: DeepQuery<UserProfile> = {
|
||||
id: 'profile-id',
|
||||
'user.details.firstName': 'John',
|
||||
'user.details.address.country': 'USA'
|
||||
};
|
||||
|
||||
// TypeScript will error if paths are incorrect
|
||||
const results = await UserProfile.getInstances(typedQuery);
|
||||
|
||||
// MongoDB query operators are supported
|
||||
const operatorQuery: DeepQuery<UserProfile> = {
|
||||
'user.details.address.country': 'USA',
|
||||
'user.details.address.city': { $in: ['New York', 'Los Angeles'] }
|
||||
};
|
||||
|
||||
const filteredResults = await UserProfile.getInstances(operatorQuery);
|
||||
```
|
||||
|
||||
### Document Lifecycle Hooks
|
||||
Implement custom logic at different stages of a document's lifecycle:
|
||||
|
||||
```typescript
|
||||
@Collection(() => db)
|
||||
class Order extends SmartDataDbDoc<Order, Order> {
|
||||
@unI()
|
||||
public id: string = 'order-id';
|
||||
|
||||
@svDb()
|
||||
public total: number;
|
||||
|
||||
@svDb()
|
||||
public items: string[];
|
||||
|
||||
// Called before saving the document
|
||||
async beforeSave() {
|
||||
// Calculate total based on items
|
||||
this.total = await calculateTotal(this.items);
|
||||
|
||||
// Validate the document
|
||||
if (this.items.length === 0) {
|
||||
throw new Error('Order must have at least one item');
|
||||
}
|
||||
}
|
||||
|
||||
// Called after the document is saved
|
||||
async afterSave() {
|
||||
// Notify other systems about the saved order
|
||||
await notifyExternalSystems(this);
|
||||
}
|
||||
|
||||
// Called before deleting the document
|
||||
async beforeDelete() {
|
||||
// Check if order can be deleted
|
||||
const canDelete = await checkOrderDeletable(this.id);
|
||||
if (!canDelete) {
|
||||
throw new Error('Order cannot be deleted');
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Connection Management
|
||||
- Always call `db.init()` before using any database features
|
||||
- Use `db.disconnect()` when shutting down your application
|
||||
- Set appropriate connection pool sizes based on your application's needs
|
||||
|
||||
### Document Design
|
||||
- Use appropriate decorators (`@svDb`, `@unI`, `@index`, `@searchable`) to optimize database operations
|
||||
- Implement type-safe models by properly extending `SmartDataDbDoc`
|
||||
- Consider using interfaces to define document structures separately from implementation
|
||||
- Mark fields that need to be searched with the `@searchable()` decorator
|
||||
|
||||
### Search Optimization
|
||||
- Create MongoDB text indexes for collections that need advanced search operations
|
||||
- Use `searchWithLucene()` for robust searches with fallback mechanisms
|
||||
- Prefer field-specific searches when possible for better performance
|
||||
- Use simple term queries instead of boolean operators if you don't have text indexes
|
||||
|
||||
### Performance Optimization
|
||||
- Use cursors for large datasets instead of loading all documents into memory
|
||||
- Create appropriate indexes for frequent query patterns
|
||||
- Use projections to limit the fields returned when you don't need the entire document
|
||||
|
||||
### Distributed Systems
|
||||
- Implement proper error handling for leader election events
|
||||
- Ensure all instances have synchronized clocks when using time-based coordination
|
||||
- Use the distributed coordinator's task management features for coordinated operations
|
||||
|
||||
### Type Safety
|
||||
- Take advantage of the `DeepQuery<T>` type for fully type-safe queries
|
||||
- Define proper types for your document models to enhance IDE auto-completion
|
||||
- Use generic type parameters to specify exact document types when working with collections
