🧐 About

Integrate Yup with Nest.js.

🎥 Demo / Working

🎈 Usage

In DTO file

• Create your own yup schema.
• Use the decorator UseSchema.

import { UseSchema } from 'nest-yup';

For example:

import * as yup from 'yup';
import { UseSchema } from 'nest-yup';

export const authSchema = yup.object({
  username: yup.string().required().min(4).max(20),
  password: yup
    .string()
    .required()
    .min(8)
    .max(20)
    .matches(
      /((?=.*\d)|(?=.*\W))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$/,
      'password too weak',
    ),
});

@UseSchema(authSchema)
export class AuthCredentialsDto {
  username: string;

  password: string;
}

In Controller file

import { YupValidationPipe } from 'nest-yup';

For example:

 @Post('/signup')
  signUp(
    @Body(YupValidationPipe)
    authCredentialsDto: AuthCredentialsDto,
  ): Promise<void> {
    return this.authService.signUp(authCredentialsDto);
  }
