HttpExceptionFilter

to Catch every unhandled exception (regardless of the exception type) and make the response as

{
    errors: [
        feilds: string[],
        messages: string,
        code: string
    ]
}

this Filter handle three types of errors

• validation errors from the dto level
• unexpected error
• validation in the business logic but at this level, you want to handle the structure of the error manually like that

throw new ConflictException({
            fields: ['feild'],
            code: 'CONFLICTS',
            message: 'your message',
          });

How to use it on the nestjs project

• in the main.ts file, import the module

import { HttpExceptionFilter } from '@mon-medic/common';

• in the bootstrap function add this line

  app.useGlobalFilters(new HttpExceptionFilter());
