Commerce Layer SDK Utils


A JavaScript Library that makes even more easier to interact with Commerce Layer API using the official JavaScript SDK.

Installation and usage

#### SDK v6.x

``ts
import CommerceLayer from "@commercelayer/sdk"
import CommerceLayerUtils, { executeBatch } from '@commercelayer/sdk-utils'

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

await executeBatch(batch)
`

#### SDK v7.x

Starting from SDK v7 you can take advantage of the tree shaking using only the resources that you really need.

`ts
import CommerceLayer, { orders, customers } from "@commercelayer/sdk"
import CommerceLayerUtils, { retrieveAll } from '@commercelayer/sdk-utils'

const cl = CommerceLayer({ organization, accessToken })
CommerceLayerUtils(cl, [ orders, customers ])

const skus = await retrieveAll('skus')
`

Resources can also be added later to CommerceLayerUtils configuration.

`ts
import CommerceLayer, { orders, customers, skus } from "@commercelayer/sdk"
import CommerceLayerUtils from '@commercelayer/sdk-utils'

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

utilsConfig.addResources(orders, customer)
utilsConfig.addResource(skus)
`

It is always possible to load the resources all together as with SDK v6 using the special bundle client implementation.

`ts
import { CommerceLayer } from "@commercelayer/sdk/bundle"
import CommerceLayerUtils from '@commercelayer/sdk-utils'

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

##### executeBatch

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

`ts
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:

`ts
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.

`ts
const skus = await retrieveAll('skus', { limit: 100 })
`

##### updateAll

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

`ts
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.

`ts

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.

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

$3

##### splitCleanup

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

`ts
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

`ts
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


`ts
const clps = await splitCleanup(clp)

const tasks = cleanupsToBatchTasks(clps)
`

}

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

##### IncludeHelper

This helper can be used to easily build the array of included resources to use in SDK query parameters.

###### Standard include

`ts
const include: QueryInclude = [ 'market', 'customer', 'customer.customer_group' ]
`

###### Include with IncludeHelper

`ts
import { Include } from '@commercelayer/sdk-utils'

const include: QueryInclude = [ Include.orders.market.build(), Include.orders.customer.build(), Include.orders.customer.customer_group.build() ]

// The same as above but using a single instance of the orders helper
const io = Include.orders
const includeSingle: QueryInclude = [ io.market.build(), io.customer.build(), io.customer.customer_group.build() ]
`

###### Include using buildInclude function

`ts
import { buildInclude } from '@commercelayer/sdk-utils'

const include: QueryInclude = buildInclude(Include.orders.market, Include.orders.customer, Include.orders.customer.customer_group)
`

###### Add resources to include to an existing query filter

`ts
import { Include } from '@commercelayer/sdk-utils'

const queryFilter: QueryParams = {}

const io = Include.orders

io.market.addTo(queryFilter)
io.customer.addTo(queryFilter)
io.customer.customer_group.addTo(queryFilter)
`

##### FilterHelper

This helper can be used to easily build the object containing the filter predicates to use in SDK query parameters.

###### Standard filter

`ts
const filter: QueryFilter = {
number_eq: '123',
market_reference_eq: 'MKT',
reference_or_customer_customer_group_reference_eq: 'REF',
status_in: 'placed,approved,cancelled',
reference_origin_not_null: 'true'
}
`

###### Filter with FilterHelper

`ts
import { Filter } from '@commercelayer/sdk-utils'

const filter: QueryFilter = {
...Filter.orders.number.eq('123'),
...Filter.orders.market.reference.eq('MKT'),
...Filter.orders.reference.or.customer.customer_group.reference.eq('REF'),
...Filter.orders.status.in('placed', 'approved', 'cancelled'),
...Filter.orders.reference_origin.not_null()
}

// The same as above but using a single instance of the orders helper
const of = Filter.orders

const filterSingle: QueryFilter = {
...of.number.eq('123'),
...of.market.reference.eq('MKT'),
...of.reference.or.customer.customer_group.reference.eq('REF'),
...of.status.in('placed', 'approved', 'cancelled'),
...of.reference_origin.not_null()
}
`

###### Filter using buildFilter function

`ts
import { buildFilter } from '@commercelayer/sdk-utils'

const filter: QueryFilter = buildFilter(
of.number.eq('123'),
of.market.reference.eq('MKT'),
of.reference.or.customer.customer_group.reference.eq('REF'),
of.status.in('placed', 'approved', 'cancelled'),
of.reference_origin.not_null()
)
