import { JoyApiError } from 'joy-api-node';

try {

    console.error('Status Code:', error.statusCode);
    console.error('Error Code:', error.code);
    console.error('Details:', error.details);
  }
}

Pagination

Most list endpoints support cursor-based pagination:

// First page
const firstPage = await joy.customers.list({ limit: 20 });

// Get next page using the last item's ID
if (firstPage.meta?.pagination?.hasNext) {
  const lastCustomerId = firstPage.data[firstPage.data.length - 1].id;
  const nextPage = await joy.customers.list({ 
    limit: 20, 
    after: lastCustomerId 
  });
}

// Get previous page using the first item's ID
if (firstPage.meta?.pagination?.hasPre) {
  const firstCustomerId = firstPage.data[0].id;
  const prevPage = await joy.customers.list({ 
    limit: 20, 
    before: firstCustomerId 
  });
}

// Include total count (may increase response time)
const withCount = await joy.customers.list({ 
  limit: 20, 
  hasCount: true 
});
console.log('Total customers:', withCount.meta?.pagination?.total);

TypeScript Support

This library is written in TypeScript and provides full type definitions:

import { Customer, Program, Activity, Reward, Tier } from 'joy-api-node';

const processCustomer = (customer: Customer) => {
  console.log(`Customer ${customer.email} has ${customer.point} points`);
};

const processProgram = (program: Program) => {
  if (program.type === 'earning') {
    console.log(`Earn ${program.earnPoint} points`);
  }
};
