How to do link validation in celebrate?

Question

npm

Hello! Can anyone tell me how links are validated in the celebrate method? Only through regular expressions? For email, Joi has an email() method, but not for links. Maybe I don't know something?) How can I do the validation here, without a regular expression?

app.post('/signup', celebrate({
  body: Joi.object().keys({
    link: Joi.string().required().pattern(/(https?:\/\/)(w{3}\.)?(((\d{1,3}\.){3}\d{1,3})|((\w-?)+\.(ru|com)))(:\d{2,5})?((\/.+)+)?\/?#?/)
  })
}));
