🧪 Quick Start Examples

Basic Flow Control

// Priority-based handler registration for security escalation
securityRegister.register('processRequest', async (payload, controller) => {
  // Use controller.abort to stop pipeline if security violation detected
  if (payload.securityViolation) {
    controller.abort('Security violation detected');
    return;
  }
  // Use controller.return to terminate pipeline with specific result
  if (payload.requiresElevation) {
    controller.return({ elevated: true, handled: true });
    return;
  }
  // Continue normal processing
}, { priority: 100 }); // Higher priority executes first

// Lower priority handlers for normal processing
securityRegister.register('processRequest', async (payload, controller) => {
  // Normal business logic
  console.log('Processing request normally');
}, { priority: 50 });

Result Collection

// Collect and merge results from multiple handlers
const result = await register.dispatchWithResult('generateReport', data, {
  result: { 
    collect: true, 
    strategy: 'merge',
    merger: (results) => ({ sections: results, summary: { total: results.length } })
  }
});

// Individual handlers can set results using controller
register.register('generateReport', (payload, controller) => {
  const report = generateSection(payload);
  controller.setResult(report); // Add result to collection
}, { priority: 1 });

Handler Introspection

// Analyze handler performance and configuration
const stats = register.getActionStats('processData');
if (stats?.executionStats) {
  console.log(`Average duration: ${stats.executionStats.averageDuration}ms`);
  console.log(`Success rate: ${stats.executionStats.successRate}%`);
  console.log(`Total executions: ${stats.executionStats.totalExecutions}`);
}

// Get registry information
const registryInfo = register.getRegistryInfo();
console.log(`Registry: ${registryInfo.name}`);
console.log(`Total actions: ${registryInfo.totalActions}`);
console.log(`Total handlers: ${registryInfo.totalHandlers}`);

Environment Filtering

// Register handlers with environment tags
register.register('deploy', deployProd, { 
  priority: 1, 
  environment: 'production',
  tags: ['deployment', 'prod'] 
});
register.register('deploy', deployDev, { 
  priority: 1, 
  environment: 'development',
  tags: ['deployment', 'dev'] 
});

// Filter by environment during dispatch
await register.dispatchWithResult('deploy', deployData, {
  filter: { environment: 'production' } // Only production handlers
});

// Filter by tags
await register.dispatch('deploy', deployData, {
  filter: { tags: ['prod'] } // Only handlers with 'prod' tag
});
