Regular expression for JavaScript:

/((?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$/

Many thanks, this course is great !

Excellent course! I appreciate that I can learn Typescript and NestJS in parallel.

It is so helpful course, thanks a lot

amazing course 🚀

Great course! 🚀

Well done @arielweinberger 🚀
Let me offer my two cents on how we can use class-validator to validate a password.

@IsStrongPassword({
    minLength: 8,
    minLowercase: 1,
    minNumbers: 1,
    minSymbols: 1,
    minUppercase: 1
})

The default error message is password is not strong enough

Cool 🚀 thanks for sharing too.

Thanks for this @arielweinberger 🔥

with class validator, you can also pass in a custom error message is its not a strong password
@IsStrongPassword({}, { message: STRONG_PASSWORD })
password: string;

export const STRONG_PASSWORD =
'Your password must be at least 8 characters long, contain at least one number and have a mixture of uppercase and lowercase letters';
