Naming rules:

  • {file-name}.{file-type}.ts: file only for user permission or lower
  • {file-name}.admin.{file-type}.ts: file only for admin permission or higher
  • {file-name}.local.{file-type}.ts: file only use in logic code, not use in service or controller folder

DTO files is divided into 2 types: input dto and output dto

Features

CQRS

In most cases, structure model --> repository --> service --> controller is sufficient. However, when our requirements become more complex, the CQRS pattern may be more appropriate and scalable.
You can defined commands and queries in commands and queries folder in each module.

Guard

  • Authentication

The boilerplate has been installed passport and jwt.
jwt token is installed in cookies that auto be sent with each request.
It can be enabled by adding JwtAuthGuard to necessary routes in controller files.

@UseGuards(JwtAuthGuard)

The JwtAuthGuard uses combination of Redis and Mysql database to optimize the speed of the app

  • Permissions

To enable the permission guard, add PermissionGuard to necessary routes in controller files.

@UseGuards(PermissionGuard)

Some permissions have been installed. Visit file src/common/constants/permission.const.ts to view detail.

Role {
  SUPER_ADMIN = 'super-admin',
  ADMIN = 'admin',
  USER = 'user',
}

User {
  CREATE = 'user:create',
  READ = 'user:read',
  UPDATE = 'user:update',
  DELETE = 'user:delete',
}
  • Account status

To enabled this guard, add this code @UseGuards(UserStatusGuard)

User account has 3 status:

  • PENDING: User register new account and account has not been activated by email
  • ACTIVE: Account has been activated by activation email
  • BLOCKED: Account has been blocked by admin

Only ACTIVE account can login to the app.

Transformers

  • Convert entity to dto to remove unnecessary properties in returned data such as password. The method toDto is installed for each entity. It can be used like that

Rate limiting

Rate limiting is configured by @nestjs/throttler. By default, limit 100 requests per 60s Visit app.module.ts to change this.

Swagger
