Difference between dto and interface #192

Closed cuongnv-dev closed 1 year ago

cuongnv-dev commented 2 years ago

Summary (요약)

  1. Could you explain the difference between dto and interface, and when we should use which?
  2. Do you have a channel or group where all members who follow this template can discuss?

@cuongnv-dev

Interfaces can not compute properties or use decorators, whereas classes can. NestJS recommends to use classes because you can add decorators from class-validator to properties such as @IsString() or @Max(20). With interfaces such a validation would only be possible outside of the interface context.

There are no channels or groups for discussion. However, if you have any questions, please leave an issue and we will answer them. thank you
