Regex Validation (Strong Patterns)

RegexValidation.js

export const regexValidators = {
  fullName: z
    .string()
    .regex(/^[a-zA-Z0-9_]{3,16}$/, "Only letters, numbers & underscore"),

  phone: z
    .string()
    .regex(/^\+91\d{10}$/, "Phone must be +91XXXXXXXXXX"),

  strongPassword: z
    .string()
    .regex(
      /^(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&]).{8,}$/,
      "Password must contain 1 uppercase, 1 number, 1 symbol, 8+ chars"
    ),
};


import { z } from "zod";
import { regexValidators } from "../services/regexValidators";

export const UserSchema = z.object({
  fullName: regexValidators.fullName,
  email: z
    .string()
    .email("Invalid email")
    .refine(
      async (val) => {
        const exists = await checkEmailExists(val);
        return !exists; // return false for error
      },
      {
        message: "Email already exists",
      }
    ),
  phone: regexValidators.phone,
  password: regexValidators.strongPassword,
});
