# Custom Resolvers
|
|
|
|
## Overview
|
|
|
|
The `CustomResolver` system provides a flexible framework for resolving property conflicts in distributed systems. It enables you to define custom resolution strategies through plugins, complete with type-safe dependencies between resolvers.
|
|
|
|
## Key Features
|
|
|
|
- **Plugin-based Architecture**: Extend functionality with custom resolvers
|
|
- **Type-Safe Dependencies**: Compile-time checking of plugin dependencies
|
|
- **Built-in Resolvers**: Common resolution strategies included
|
|
- **Efficient Processing**: Only processes changed deltas
|
|
- **Deterministic Results**: Same input always produces the same output
|
|
|
|
## Core Concepts
|
|
|
|
1. **Resolver Plugins**: Implement resolution logic for properties
|
|
2. **Dependency Management**: Declare and manage dependencies between plugins
|
|
3. **State Management**: Maintain and update state based on incoming deltas
|
|
4. **Resolution Pipeline**: Process updates and resolve final values
|
|
|
|
## Getting Started
|
|
|
|
```typescript
|
|
import { CustomResolver } from '../src/views/resolvers/custom-resolvers';
|
|
import { LastWriteWinsPlugin } from '../src/views/resolvers/custom-resolvers/plugins';
|
|
import { Hyperview } from '../src/views/hyperview';
|
|
|
|
// Create a hyperview
|
|
const hyperview = new Hyperview();
|
|
|
|
// Create a resolver with a last-write-wins strategy
|
|
const resolver = new CustomResolver(hyperview, {
|
|
myProperty: new LastWriteWinsPlugin()
|
|
});
|
|
|
|
// Process updates through the hyperview
|
|
// hyperview.applyDelta(delta);
|
|
|
|
// Get resolved values for specific entities
|
|
const result = resolver.resolve(['entity1', 'entity2']);
|
|
|
|
// Or get all resolved values
|
|
const allResults = resolver.resolveAll();
|
|
```
