add rename file

[AmineHouari98]

as the title said it would be nice to add a way to add a middleware to rename uploaded files before saving to local storage , i think this feature is a must when working with files !

Hi, maybe add a callback function to the configuration of FormDataInterceptorConfig to get the filename before saving it to local storage?

Could you guide me with a callback function to the configuration of FormDataInterceptorConfig to get the filename?

Hi @AmineHouari98 @chhonhourseng

If you are using DTO, you can achieve this with @Transform decorator (class-transformer package):

@Transform(({ value }: { value: MemoryStoredFile }) => {
    value.originalName = 'new name';
    return value;
  })
file: MemoryStoredFile;
