import CommerceLayer from "@commercelayer/sdk"
import CommerceLayerUtils, { executeBatch } from '@commercelayer/sdk'

const cl = CommerceLayer({ organization, accessToken })
CommerceLayerUtils(cl)

await executeBatch(batch)

Common functions

executeBatch

This function allows to prepare and then execute a number of API calls without having to worry about current rate limits.

for (const emailAddress of emailList) {
    const task: Task = {
      resourceType: "customers",
      operation: "create",
      resource: { email: emailAddress } as CustomerCreate,
      onSuccess: { callback: sendEmail },
      onFailure: { errorHandler: handleError }
    }
    tasks.push(task)
  }

  const batch: Batch = {
    tasks,
    options: { refreshToken: refreshAccessToken }
  }


await executeBatch(batch)

In the example above the onSuccess and onFailure callbacks have been used to handle the task result in case of success or failure of the execution.

It's also possible to fill the resource attributes taking values from the result of the previous batch step. In the following example we are updating a resource taking its id from a previous retrieve or create task:

const task: Task = {
    resourceType: "customers",
    operation: "update",
    prepareResource: (res: TaskResourceParam, last: TaskResourceResult): TaskResourceParam => {
        return {
          ...res,
          id: last.id,
          reference: 'new-reference'
        }
      }
  }

retrieveAll

This function allows to fetch all existing resources of a specific type executing all necessary API requests respecting current API rate limits. The limit option can be used to retrieve only a limited number of resources.

const skus = await retrieveAll<Sku>('skus', { limit: 100 })

updateAll

This function allows to modify a set of resources of a specific type, using a filter to identify them.

const skuData = { reference_origin: 'legacy-system-0' }

const filters = { created_at_lt: '2023-01-01' }

const updateResult = await updateAll('skus', skuData, { filters })

deleteAll

This function allows to delete a set of resources of a specific type, using a filter to identify them.

const filters = { created_at_lt: '2023-01-01', reference_origin_eq: 'legacy-system-0' }

const deleteResult = await deleteAll('skus', { filters })

retrievePage

This function allows to fetch a specific subset of resources defining page attributes that are not permitted by the API and using all the standard common filters. An error will be thrown if the page parameters are not compatible with the number of existing resources.

 const skus = await retrievePage<Sku>('skus', { pageNumber: 16, pageSize: 139, sort: ['code'] })

Cleanups

splitCleanup

Split cleanup in multiple cleanups respecting the maximum limit of resources included

const clp: CleanupCreate = {
 resource_type: 'customers',
 filters: { created_at_gt: '2020-01-01'}
}

const splitClp: CleanupCreate[] = await splitCleanup(clp)

executeCleanup

Split cleanup in multiple cleanups respecting the maximum limit of resources included and execute them

const clp: CleanupCreate = {
 resource_type: 'customers',
 filters: { created_at_gt: '2020-01-01'}
}

const execClp: CleanupResult[] = await executeCleanup(clp)

cleanupsToBatchTasks

Convert a list of cleanups generated by splitCleanup to a list of tasks that can be executed by the function executeBatch

const clps = await splitCleanup(clp)

const tasks = cleanupsToBatchTasks(clps)

---

Exports

splitExport

Split an export in multiple exports respecting the maximum limit of resources included

const exp: ExportCreate = {
 resource_type: 'customers',
 filters: { created_at_gt: '2020-01-01'}
}

const splitExp: ExportCreate[] = await splitExport(exp)

executeExport

Split an export in multiple exports respecting the maximum limit of resources included and execute them

const exp: ExportCreate = {
 resource_type: 'customers',
 filters: { created_at_gt: '2020-01-01'}
}

const execExp: ExportResult[] = await executeExport(exp)

exportsToBatchTasks

Convert a list of exports generated by splitExport to a list of tasks that can be executed by the function executeBatch

const exps = await splitExport(exp)

const tasks = exportsToBatchTasks(exps)

---

Imports

splitImport

Split an import in multiple imports respecting the maximum limit of inputs included

const exp: ImportCreate = {
 resource_type: 'customers',
 inputs: [
  { ... },
  { ... },
  ...
  { ... }
 ]
}

const splitImp: ImportCreate[] = await splitImport(imp)

executeImport

const exp: ImportCreate = {
 resource_type: 'customers',
 inputs: [
  { ... },
  { ... },
  ...
  { ... }
 ]
}

const execImp: ImportResult[] = await executeImport(imp)

importsToBatchTasks

Webhooks

denormalizePayload

This function takes in input the payload of a webhook in JSON format and transform it in the appropriate typed resource to be used with the official Typescript SDK.

const shipment = denormalizePayload<Shipment>(webhookPayload)
