Baskets API

Overview

The Baskets API provides complete shopping cart functionality with item management, status tracking, and checkout capabilities. Returns BasketInstance objects with direct property access.

import { Baskets, BasketStatus } from 'lua-cli';

// Create basket - returns BasketInstance
const basket = await Baskets.create({ currency: 'USD' });

// Direct property access
console.log(basket.itemCount);    // 0
console.log(basket.totalAmount);  // 0
console.log(basket.status);       // "active"

// Add item using instance method
await basket.addItem({
  id: productId,
  price: 29.99,
  quantity: 2
});

// Access updated properties directly
console.log(basket.itemCount);    // 2
console.log(basket.totalAmount);  // 59.98

// Checkout using instance method
const order = await basket.placeOrder({
  shippingAddress: {...},
  paymentMethod: 'stripe'
});

Direct Access

Access basket.itemCount not basket.common.itemCount

Instance Methods

Built-in methods like addItem(), placeOrder()

Auto-Sync

Properties update after method calls

Complete Shopping Flow Example

import { LuaTool, Products, Baskets } from 'lua-cli';
import { z } from 'zod';

// Tool 1: Create Basket
export class CreateBasketTool implements LuaTool {
  name = "create_basket";
  description = "Start a new shopping session";
  inputSchema = z.object({});

  async execute(input: any) {
    const basket = await Baskets.create({
      currency: 'USD',
      metadata: { createdBy: 'chat' }
    });
    
    return {
      basketId: basket.id,
      message: "Shopping basket created! Start adding items."
    };
  }
}

// Tool 2: Add to Basket
export class AddToBasketTool implements LuaTool {
  name = "add_to_basket";
  description = "Add a product to shopping basket";
  
  inputSchema = z.object({
    basketId: z.string(),
    productId: z.string(),
    quantity: z.number().min(1).default(1)
  });

  async execute(input: z.infer<typeof this.inputSchema>) {
    // Get product details
    const product = await Products.getById(input.productId);
    
    // Check stock
    if (!product.inStock) {
      return {
        success: false,
        message: `${product.name} is out of stock`
      };
    }
    
    // Add to basket
    const basket = await Baskets.addItem(input.basketId, {
      id: input.productId,
      price: product.price,
      quantity: input.quantity,
      SKU: product.sku
    });
    
    return {
      basketId: basket.id,
      itemCount: basket.common.itemCount,
      total: `$${basket.common.totalAmount.toFixed(2)}`,
      message: `Added ${input.quantity}x ${product.name} to basket`
    };
  }
}

// Tool 3: Checkout
export class CheckoutTool implements LuaTool {
  name = "checkout";
  description = "Complete purchase and create order";
  
  inputSchema = z.object({
    basketId: z.string(),
    shippingAddress: z.object({
      street: z.string(),
      city: z.string(),
      state: z.string(),
      zip: z.string()
    }),
    paymentMethod: z.string().default('stripe')
  });

  async execute(input: z.infer<typeof this.inputSchema>) {
    // Get basket
    const basket = await Baskets.getById(input.basketId);
    
    // Verify basket has items
    if (basket.common.itemCount === 0) {
      return {
        success: false,
        message: "Cannot checkout empty basket"
      };
    }
    
    // Place order
    const order = await Baskets.placeOrder({
      shippingAddress: input.shippingAddress,
      paymentMethod: input.paymentMethod
    }, input.basketId);
    
    return {
      success: true,
      orderId: order.id,
      total: `$${basket.common.totalAmount.toFixed(2)}`,
      status: order.common.status,
      message: "Order placed successfully!"
    };
  }
}

Best Practices

Verify Basket Exists

const basket = await Baskets.getById(basketId);

if (!basket) {
  throw new Error(`Basket not found: ${basketId}`);
}

Check Items Before Checkout

const basket = await Baskets.getById(basketId);

if (basket.common.itemCount === 0) {
  return {
    success: false,
    message: "Cannot checkout empty basket"
  };
}

Store Metadata

Use metadata for tracking:

await Baskets.updateMetadata(basketId, {
  source: 'mobile_app',
  promotionCode: 'SUMMER2025',
  referralSource: 'instagram'
});

Handle Abandoned Baskets

// Mark as abandoned after timeout
setTimeout(async () => {
  await Baskets.updateStatus(
    basketId,
    BasketStatus.ABANDONED
  );
}, 30 * 60 * 1000); // 30 minutes

Common Patterns

View Cart

export class ViewCartTool implements LuaTool {
  async execute(input: { basketId: string }) {
    const basket = await Baskets.getById(input.basketId);
    
    return {
      items: basket.common.items.map(item => ({
        product: item.id,
        quantity: item.quantity,
        price: `$${item.price}`,
        subtotal: `$${(item.price * item.quantity).toFixed(2)}`
      })),
      total: `$${basket.common.totalAmount.toFixed(2)}`,
      itemCount: basket.common.itemCount
    };
  }
}

Apply Discount

export class ApplyDiscountTool implements LuaTool {
  async execute(input: { basketId: string; code: string }) {
    const basket = await Baskets.getById(input.basketId);
    
    // Apply discount logic
    const discountPercent = getDiscountForCode(input.code);
    const discountAmount = basket.common.totalAmount * (discountPercent / 100);
    
    await Baskets.updateMetadata(input.basketId, {
      discountCode: input.code,
      discountAmount,
      originalTotal: basket.common.totalAmount
    });
    
    return {
      discount: `${discountPercent}%`,
      saved: `$${discountAmount.toFixed(2)}`,
      newTotal: `$${(basket.common.totalAmount - discountAmount).toFixed(2)}`
    };
  }
}
