Able to validate invalid email

[M0hammedImran]

Currently, I'm able to pass this as email and get no issues.

imran@345934898929^&^&*&**#$%*&%#imran.com

pawan.anand@%9y8325&%#%$&#$R%&#$%R&#$%R&%#$R%%^^%5rw3ewe.r.ef.d.d.d.d.d.aaaa.wef.co

Are you able to give a code example?

[fvckDesa]

const scheme = z.string().email();
const email = "pawan.anand@%9y8325&%#%$&#$R%&#$%R&#$%R&%#$R%%^^%5rw3ewe.r.ef.d.d.d.d.d.aaaa.wef.co";
scheme.parse(email); //don't throw an error

According to this site (link) the domain can contains:

• max 63 characters
• uppercase and lowercase Latin letters
• numbers 0-9 (not only numbers)
• one "-" not in start or end

Behind the scenes zod uses this regex to validate email addresses:

zod/src/types.ts

Lines 523 to 524 in a57fc2d

	const emailRegex =
	/^(([^<>()[\].,;:\s@"]+(\.[^<>()[\].,;:\s@"]+)*)|(".+"))@((?!-)([^<>()[\].,;:\s@"]+\.)+[^<>()[\].,;:\s@"]{1,})[^-<>()[\].,;:\s@"]$/i;

If you would like a different regex to do this, you can use something like these:

// completely custom regex
const schema = z.string().regex( /some regex/ )

// custom regex that must match the zod email regex
const schema = z.string().email().regex( /some regex/ )

I created a pull request and for me this is a valid change because can prevent some issues

Another example of email that works but, I believe, is invalid:
invalid@foo.....com

Another example of email that works but, I believe, is invalid: invalid@foo.....com

This doesn't pass the test for the default regex.

I disagree.

const schema = z.string().email()
console.log( schema.safeParse( 'invalid@foo.....com' ).success ) // true
