add missing IP addresses string validations

[geko1971]

Hello Stefan, first of all congrats for your really helpful lib!

It would be great to add the missing string format validations that are part of JSON format assertion vocabulary, maybe starting from the ones that maps easily with zod assertions, such as IP Addresses validations.

That could only require a small change to src/parsers/parseString.ts module:

import { JSONSchema7 } from "json-schema";

export const parseString = (schema: JSONSchema7 & { type: "string" }) => {
  let r = "z.string()";
  if (schema.pattern)
    r += `.regex(new RegExp(${JSON.stringify(schema.pattern)}))`;
  if (schema.format === "email") r += ".email()";
+  if (schema.format === "ip") r += ".ip()";
+  if (schema.format === "ipv4") r += ".ip({ version: "v4" })";
+  if (schema.format === "ipv6") r += ".ip({ version: "v6" })";
  else if (schema.format === "uri") r += ".url()";
  else if (schema.format === "uuid") r += ".uuid()";
  else if (schema.format === "date-time") r += ".datetime()";
  if (typeof schema.minLength === "number") r += `.min(${schema.minLength})`;
  if (typeof schema.maxLength === "number") r += `.max(${schema.maxLength})`;
  return r;
};

Thank you!

hello i'd like to achieve the same for date fields

"birthday": {
                  "title": "Birthday",
                  "type": "string",
                  "format": "date"
                },

@grmkris Date and time formats have no equivalents in Zod, sorry

[grmkris]

we could do z.coerce.date() ?
