Joi 验证字符串排除 uri

Question

I'm trying to validate string parameters and I want to exclude/reject when it matches URI pattern. My current joi is Joi.string().trim().min(2).max(30)

Answer 1

You can use regex to implement your URI pattern and add {invert: true} to regex to reject it.

Joi.string().regex(/^[a-zA-Z0-9]{3,30}$/, {invert: true})
