Methods

atomicPhase_

▸ Protected atomicPhase_<TResult, TError>(work, isolationOrErrorHandler?, maybeErrorHandlerOrDontFail?): Promise<TResult>

Wraps some work within a transactional block. If the service already has a transaction manager attached this will be reused, otherwise a new transaction manager is created.

Type parameters

Name
TResult
TError

Parameters

Name	Type	Description
work	(transactionManager: EntityManager) => Promise<TResult>	the transactional work to be done
isolationOrErrorHandler?	IsolationLevel | (error: TError) => Promise<void | TResult>	the isolation level to be used for the work.
maybeErrorHandlerOrDontFail?	(error: TError) => Promise<void | TResult>	Potential error handler

Returns

Promise<TResult>

the result of the transactional work

---

create

▸ create(payload): Promise<IdempotencyKey>

Creates an idempotency key for a request. If no idempotency key is provided in request, we will create a unique identifier.

Parameters

Name	Type	Description
payload	CreateIdempotencyKeyInput	payload of request to create idempotency key for

Returns

Promise<IdempotencyKey>

the created idempotency key

Defined in

---

initializeRequest

▸ initializeRequest(headerKey, reqMethod, reqParams, reqPath): Promise<IdempotencyKey>

Execute the initial steps in a idempotent request.

Parameters

Name	Type	Description
headerKey	string	potential idempotency key from header
reqMethod	string	method of request
reqParams	Record<string, unknown>	params of request
reqPath	string	path of request

Returns

Promise<IdempotencyKey>

the existing or created idempotency key

Defined in

packages/medusa/dist/services/idempotency-key.d.ts:22

---

lock

▸ lock(idempotencyKey): Promise<IdempotencyKey>

Locks an idempotency.

Parameters

Name	Type	Description
idempotencyKey	string	key to lock

Returns

Promise<IdempotencyKey>

result of the update operation

Defined in

---

retrieve

▸ retrieve(idempotencyKeyOrSelector): Promise<IdempotencyKey>

Retrieves an idempotency key

Parameters

Name	Type	Description
idempotencyKeyOrSelector	string | Selector<IdempotencyKey>	key or selector to retrieve

Returns

Promise<IdempotencyKey>

idempotency key

update

▸ update(idempotencyKey, update): Promise<IdempotencyKey>

Locks an idempotency.

Parameters

Name	Type	Description
idempotencyKey	string	key to update
update	DeepPartial<IdempotencyKey>	update object

Returns

Promise<IdempotencyKey>

result of the update operation

workStage

▸ workStage(idempotencyKey, callback): Promise<IdempotencyKey>

Performs an atomic work stage. An atomic work stage contains some related functionality, that needs to be transactionally executed in isolation. An idempotent request will always consist of 2 or more of these phases. The required phases are "started" and "finished".

Parameters

Name	Type	Description
idempotencyKey	string	current idempotency key
callback	(transactionManager: EntityManager) => Promise<IdempotencyCallbackResult>	functionality to execute within the phase

Returns

Promise<IdempotencyKey>

new updated idempotency key
