Usage

1. Create a FormRequest

php artisan make:request UserRequest

Example:

public function rules()
{
    return [
        'name' => 'required|string|max:255',
        'email' => 'required|email|unique:users,email',
        'password' => 'required|min:8|confirmed',
    ];
}

public function messages()
{
    return [
        'name.required' => 'Name is required.',
        'email.email' => 'Email must be valid.',
    ];
}

2. Generate JSON Schema

php artisan form:sync UserRequest

This will create: resources/forms/user_request.json

To sync all FormRequests:

php artisan form:sync --all

3. Use in React

import { useFormSync } from "@/hooks/useFormSync";
import userSchema from "../forms/user_request.json";

export default function RegisterForm() {
  const { register, handleSubmit, errors } = useFormSync(userSchema);

  const onSubmit = (data) => {
    console.log("Submitted:", data);
  };

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <input {...register("name")} placeholder="Name" />
      {errors.name && <span>{errors.name}</span>}

      <input {...register("email")} placeholder="Email" />
      {errors.email && <span>{errors.email}</span>}

      <input type="password" {...register("password")} placeholder="Password" />
      {errors.password && <span>{errors.password}</span>}

      <button type="submit">Register</button>
    </form>
  );
}

4. Use in Vue

import { useFormSync } from "@/composables/useFormSync";
import userSchema from "../forms/userrequest.json";

export default {
  setup() {
    const { register, handleSubmit, state } = useFormSync(userSchema);

    const onSubmit = (data) => console.log("Submitted:", data);

    return { register, handleSubmit, state, onSubmit };
  }
}
