Validación de DTO de Nest.JS

Mi DTO es

 @Expose() @IsNotEmpty() @IsJSON({ each: true }) filesRole: string

filesRole es algo así: [{"file": "14125.png", "role": "bg"}, {"file": "x12.png", "role": "cover"}]

Quiero validar el role para que sea bg o cover .

Puedes probarlo con enumeración:

 export enum Role { bg = 'bg', cover = 'cover', }
 @IsEnum(Role) @Expose() @IsNotEmpty() @IsJSON({ each: true }) filesRole: Role

actualice su DTO principal:

 @Expose() @IsNotEmpty() @IsArray() @ValidateNested({ each: true }) filesRole: Data[];

DTO de datos:

 export class Data { @IsNotEmpty() @IsString() file: string; @IsNotEmpty() @IsString() @IsIn(Object.values(roleEnum)) role: roleEnum; }

roleEnum :

 export enum roleEnum { bg = 'bg', cover = 'cover', }
