email validation doesn't work?

[mblandr]

import { Type } from '@sinclair/typebox'; import { Value } from '@sinclair/typebox/value';

const T = Type.String({ format: 'email' }); const a = 'test@gmail.com'; const res = Value.Check(T, a); console.log(res); result is false.Why?

@mblandr Hi,

TypeBox doesn't configure any strings formats by default, you will need to configure them yourself. The following configures the email format, you can add additional format checkers if you need.

import { Type, FormatRegistry } from '@sinclair/typebox'
import { Value } from '@sinclair/typebox/value'

FormatRegistry.Set('email', value => /^[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?$/i.test(value))

const Email = Type.String({ format: 'email' })

Value.Check(Email, "user@domain.com") // true
Value.Check(Email, "not-a-email")     // false

You can find some common formats here Hope this helps S
