In this section of the documentation, you will find resources to learn more about the Cart Module and how to use it in your application.
Medusa has cart related features available out-of-the-box through the Cart Module. A module is a standalone package that provides features for a single domain. Each of Medusa's commerce features are placed in commerce modules, such as this Cart Module.
In your Medusa application, you build flows around commerce modules. A flow is built as a Workflow, which is a special function composed of a series of steps that guarantees data consistency and reliable roll-back mechanism.
You can build custom workflows and steps. You can also re-use Medusa's workflows and steps, which are provided by the @medusajs/medusa/core-flows
package.
For example:
1import { 2 createWorkflow, 3 WorkflowResponse,4 createStep,5 StepResponse,6} from "@medusajs/framework/workflows-sdk"7import { Modules } from "@medusajs/framework/utils"8 9const createCartStep = createStep(10 "create-cart",11 async ({}, { container }) => {12 const cartModuleService = container.resolve(Modules.CART)13 14 const cart = await cartModuleService.createCarts({15 currency_code: "usd",16 shipping_address: {17 address_1: "1512 Barataria Blvd",18 country_code: "us",19 },20 items: [21 {22 title: "Shirt",23 unit_price: 1000,24 quantity: 1,25 },26 ],27 })28 29 return new StepResponse({ cart }, cart.id)30 },31 async (cartId, { container }) => {32 if (!cartId) {33 return34 }35 const cartModuleService = container.resolve(Modules.CART)36 37 await cartModuleService.deleteCarts([cartId])38 }39)40 41export const createCartWorkflow = createWorkflow(42 "create-cart",43 () => {44 const { cart } = createCartStep()45 46 return new WorkflowResponse({47 cart,48 })49 }50)
You can then execute the workflow in your custom API routes, scheduled jobs, or subscribers:
