RegExp is not being parsed correctly into pattern property

kylekirkby commented 1 week ago

We've got a custom URL schema that is failing to be correctly translated to a pattern property.

export const urlRegex =
  /^((([A-Za-z]{3,9}:(?:\/\/)?)(?:[-;:&=+$,\w]+@)?[A-Za-z0-9.-]+|(?:www\.|[-;:&=+$,\w]+@)[A-Za-z0-9.-]+)((?:\/[+~%,/.\w\-_]*)?\??(?:[-+=&;%@.\w:()_]*)#?(?:[.!/\\\w]*))?)/;

export const URLSchema = z
  .string()
  .min(1)
  .max(1000)
  .regex(urlRegex, { message: "Please enter a valid URL" })
  .brand("url");

When loading Swagger UI we're getting unknown escape sequence.

It looks like we need to double escape backslashes in JSON?

Cheers!

I'm able to successfully construct the regexp from the JSON schema produced from your example, so I need some help reproducing this @kylekirkby

Could you check the Swagger UI code to see what specifically produces the error?

Added some tests for it here btw https://github.com/StefanTerdell/zod-to-json-schema/blob/master/test/issues.test.ts#L48
