Simple Usage

​
Scheduling a Recipe

import { recipe } from 'praisonai-ts';

// Schedule a recipe
const scheduler = await recipe.schedule('my-recipe', {
  interval: 'hourly',
  maxRetries: 3,
  timeoutSec: 300,
  maxCostUsd: 1.00,
  runImmediately: true,
});

// Start the scheduler
scheduler.start();

// Get statistics
const stats = scheduler.getStats();
console.log(`Executions: ${stats.totalExecutions}`);
console.log(`Success rate: ${stats.successRate}%`);

// Stop when done
scheduler.stop();

​
Scheduler Interface

interface RecipeScheduler {
  recipeName: string;
  interval: string;
  isRunning: boolean;
  
  start(): void;
  stop(): void;
  getStats(): SchedulerStats;
}

interface SchedulerStats {
  totalExecutions: number;
  successfulExecutions: number;
  failedExecutions: number;
  successRate: number;
  totalCost: number;
  lastExecutionAt?: Date;
  nextExecutionAt?: Date;
}

​
Using AgentScheduler Directly

import { Agent, AgentScheduler } from 'praisonai-ts';

// Create agent
const agent = new Agent({
  name: 'News Monitor',
  instructions: 'Monitor and summarize AI news',
});

// Create scheduler
const scheduler = new AgentScheduler({
  agent,
  task: 'Check for latest AI news',
  timeout: 300,
  maxCost: 1.00,
});

// Start with interval
scheduler.start({
  scheduleExpr: 'hourly',
  maxRetries: 3,
  runImmediately: true,
});

// Monitor
console.log(`Running: ${scheduler.isRunning}`);
console.log(`Stats: ${JSON.stringify(scheduler.getStats())}`);

// Stop
scheduler.stop();

​
Configuration

​
TEMPLATE.yaml Runtime Block

runtime:
  schedule:
    enabled: true
    interval: "hourly"
    max_retries: 3
    run_immediately: false

maxRetries3Retry attempts on failure
timeoutSec300Timeout per execution
maxCostUsd1.00Budget limit

​
Error Handling

import { recipe, SchedulerError } from 'praisonai-ts';

try {
  const scheduler = await recipe.schedule('my-recipe', {
    interval: 'hourly',
    maxCostUsd: 0.50,
  });
  
  scheduler.start();
  
  // Monitor for errors
  scheduler.on('error', (error) => {
    console.error(`Execution failed: ${error.message}`);
  });
  
  scheduler.on('budgetExceeded', () => {
    console.log('Budget limit reached, stopping');
    scheduler.stop();
  });
  
} catch (error) {
  if (error instanceof SchedulerError) {
    console.error(`Scheduler error: ${error.message}`);
  }
}

​
Best Practices

Prevent runaway costs
Match task requirements
Implement retry logic
Track success rates
Always call stop() when done
