neohelden-commons-nestjs-server-transactional
This module provides a database-agnostic transactional service for NestJS applications. The transactional service is build in a way, that any underlying database or transaction-supporting service can be used.
Transaction Bundle
The decisions are available to the Application using decorators. An example to load the module with TypeORM is:
import {
TransactionHelper,
Transactional,
} from "@neohelden/nestjs-server-transactional";
class BookService {
@Transaction()
async save(book: Book): Promise<Book> {
repository.save(book);
return book;
}
}
class Repository {
constructor(private readonly helper: TransactionHelper) {}
@Transactional()
async save(book: Book): Promise<Book> {
return helper.transaction(async (dataManager) => {
dataManager.save(book);
});
}
}
Configuration
The configuration of this module is accomplished using NestJS Dynamic modules.
Therefore import the TransactionModule
in your AppModule
and provide the configuration.
Example:
TransactionModule.forRoot({
getDataManager: async () => {
return new DataManager();
},
});
