# DWN Plugin Architecture
|
||||
|
||||
The Sonr project implements a flexible and secure plugin system for Decentralized Web Nodes (DWN), enabling modular and extensible functionality.
|
||||
|
||||
## Overview
|
||||
|
||||
The plugin architecture is designed to:
|
||||
|
||||
- Support dynamic loading of WebAssembly (WASM) plugins
|
||||
- Provide a standardized interface for plugin interactions
|
||||
- Enable secure, isolated execution of plugins
|
||||
|
||||
## Core Components
|
||||
|
||||
### Plugin Manager
|
||||
|
||||
The `PluginManager` manages plugin lifecycle and interactions:
|
||||
|
||||
```go
|
||||
type PluginManager struct {
|
||||
plugins map[string]Plugin
|
||||
actors map[string]Actor
|
||||
}
|
||||
|
||||
type Plugin interface {
|
||||
Initialize(config map[string]any) error
|
||||
Execute(method string, payload []byte) ([]byte, error)
|
||||
Close() error
|
||||
}
|
||||
```
|
||||
|
||||
### Plugin Configuration
|
||||
|
||||
Plugins are configured through a structured configuration:
|
||||
|
||||
```go
|
||||
type PluginConfig struct {
|
||||
ID string // Unique plugin identifier
|
||||
Type string // Plugin type (e.g., "motor", "crypto")
|
||||
Path string // WASM module path
|
||||
Environment map[string]any // Plugin-specific environment variables
|
||||
}
|
||||
```
|
||||
|
||||
## Loading and Initializing Plugins
|
||||
|
||||
### Basic Plugin Loading
|
||||
|
||||
```go
|
||||
func (pm *PluginManager) LoadPlugin(config PluginConfig) error {
|
||||
// Load WASM module
|
||||
module, err := extism.Load(config.Path)
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
|
||||
// Initialize plugin
|
||||
plugin := &WASMPlugin{
|
||||
module: module,
|
||||
config: config,
|
||||
}
|
||||
|
||||
// Store in plugin registry
|
||||
pm.plugins[config.ID] = plugin
|
||||
}
|
||||
```
|
||||
|
||||
### Actor-Based Plugin Management
|
||||
|
||||
```go
|
||||
func (pm *PluginManager) CreateActor(pluginID string) (*Actor, error) {
|
||||
plugin, exists := pm.plugins[pluginID]
|
||||
if !exists {
|
||||
return nil, errors.New("plugin not found")
|
||||
}
|
||||
|
||||
actor := NewActor(plugin)
|
||||
pm.actors[actor.ID] = actor
|
||||
|
||||
return actor, nil
|
||||
}
|
||||
```
|
||||
|
||||
## Plugin Execution Workflow
|
||||
|
||||
1. Plugin is loaded from WASM module
|
||||
2. Configuration is applied
|
||||
3. Plugin is initialized
|
||||
4. Specific methods can be invoked through a standardized interface
|
||||
|
||||
### Example Plugin Execution
|
||||
|
||||
```go
|
||||
func ExecutePluginMethod(pluginID, method string, payload []byte) ([]byte, error) {
|
||||
plugin := pluginManager.plugins[pluginID]
|
||||
return plugin.Execute(method, payload)
|
||||
}
|
||||
```
|
||||
|
||||
## Configuration and Environment
|
||||
|
||||
### Plugin Environment Variables
|
||||
|
||||
```json
|
||||
{
|
||||
"motor_plugin": {
|
||||
"enclave_config": { ... },
|
||||
"chain_id": "sonr-testnet-1",
|
||||
"log_level": "debug"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Error Handling and Logging
|
||||
|
||||
```go
|
||||
type PluginError struct {
|
||||
Code string
|
||||
Message string
|
||||
Details map[string]any
|
||||
}
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
- WASM plugins run in an isolated sandbox
|
||||
- Limited access to system resources
|
||||
- Runtime restrictions prevent malicious behavior
|
||||
- Cryptographic verification of plugin modules
|
||||
|
||||
## Plugin Types
|
||||
|
||||
1. **Crypto Plugins**: Cryptographic operations
|
||||
2. **Motor Plugins**: MPC and token management
|
||||
3. **DID Plugins**: Decentralized Identity operations
|
||||
4. **Custom Plugins**: Application-specific extensions
|
||||
|
||||
## Best Practices
|
||||
|
||||
- Keep plugins small and focused
|
||||
- Use standardized interfaces
|
||||
- Implement comprehensive error handling
|
||||
- Validate all plugin inputs
|
||||
- Monitor plugin performance
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
For advanced plugin configuration and deployment, refer to the [PDK Configuration Guide](/blockchain/modules/dwn/configuration).
