MongoEntityService

MongoEntityService<T> is an abstract class that sits between MongoService and the concrete service classes. It adds the low-level database primitives (_create, _count, _findById, _findMany, _update, _replace, _delete…), the interceptor-aware _executeCommand loop, and the lifecycle hooks called by MongoCollectionService and MongoSingletonService.

You do not extend it directly. Extend MongoCollectionService or MongoSingletonService instead.

import { MongoEntityService } from '@opra/mongodb';

Hierarchy: ServiceBase → MongoService → MongoEntityService

Lifecycle hooks

Override these in MongoCollectionService or MongoSingletonService subclasses. The base implementations are no-ops.

Hook	Signature
_beforeCreate(command)	(CreateCommand<T>) => Promise<void>
_afterCreate(command, result)	(CreateCommand<T>, PartialDTO<T>) => Promise<void>
_beforeReplace(command)	(ReplaceCommand<T>) => Promise<void>
_afterReplace(command, result)	(ReplaceCommand<T>, PartialDTO<T>) => Promise<void>
_beforeUpdate(command)	(UpdateOneCommand<T>) => Promise<void>
_afterUpdate(command, result)	(UpdateOneCommand<T>, PartialDTO<T> | undefined) => Promise<void>
_beforeUpdateMany(command)	(UpdateManyCommand<T>) => Promise<void>
_afterUpdateMany(command, affected)	(UpdateManyCommand<T>, number) => Promise<void>
_beforeDelete(command)	(DeleteCommand<T>) => Promise<void>
_afterDelete(command, affected)	(DeleteCommand<T>, number) => Promise<void>
_beforeDeleteMany(command)	(DeleteCommand<T>) => Promise<void>
_afterDeleteMany(command, affected)	(DeleteCommand<T>, number) => Promise<void>

Interfaces

MongoEntityService.Options

Identical to MongoService.Options. No additional properties.

Command interfaces

Command objects are passed to lifecycle hooks. Each interface extends MongoService.CommandInfo and narrows the crud discriminant.

CreateCommand<T>

Property	Type
crud	'create'
input	PartialDTO<T>
options	CreateOptions

CountCommand<T>

Property	Type
crud	'read'
options	CountOptions<T>

DeleteCommand<T>

Property	Type
crud	'delete'
documentId	AnyId
options	DeleteOptions<T>

DistinctCommand<T>

Property	Type
crud	'read'
field	string
options	DistinctOptions<T>

ExistsCommand<T>

Property	Type
crud	'read'
documentId	AnyId
options	ExistsOptions<T>

FindOneCommand<T>

Property	Type
crud	'read'
documentId	AnyId

UpdateOneCommand<T>

Property	Type
crud	'update'
documentId	AnyId
input	MongoPatchDTO<T> (mutually exclusive with inputRaw)
inputRaw	mongodb.UpdateFilter<T> (mutually exclusive with input)
options	UpdateOneOptions<T>

UpdateManyCommand<T>

Same shape as UpdateOneCommand<T> but without documentId.
