Hello @thobui14ig , can you give more information about what you want to do if possible?

Do you want to run your code in one transaction?

await this.resourcesRepository.save(data);
await this.userService.saveUser();

Hi, @thobui14ig.

1. You need to connect this library (https://github.com/Aliheym/typeorm-transactional#initialization) and example for Nest.js (https://github.com/Aliheym/typeorm-transactional#usage)
2. You need to use Transactional decorator in the method that contains a code that you want to "wrap" in the one transactions. For example it can be a controller method:

@Patch('/users/:id`)
@Transactional()
async updateUser(data) {
    await this.resourcesRepository.save(data);
    await this.userService.saveUser();
}

or it can be any other method:

class UsersService {
@Transactional()
async updateUser(data) {
    await this.resourcesRepository.save(data);
    await this.userService.saveUser();
}

You can ask questions if you have troubles with something.
