Usage

1. Define your action

import { SafeAction } from "react-zod-safe-action";
import { z } from "zod";

// create a safe action and reuse anywhere
export const actionClient = new SafeAction();

// Define your input schema
const loginSchema = z.object({
  email: z.string().email(),
  password: z.string().min(8)
});

// Create a safe action
const loginAction = actionClient.schema(loginSchema).action(async (data) => {
  // Your login logic here
  return { success: true };
});

2. Use the action in your component

import { useAction } from "react-zod-safe-action";

function LoginForm() {
  const { execute, status, loading } = useAction(loginAction, {
    onSuccess: (data) => {
      console.log("Login successful", data);
    },
    onError: ({ error, input }) => {
      console.log("Login failed", error);
    }
  });

  const handleSubmit = (e) => {
    e.preventDefault();
    execute({
      email: "user@example.com",
      password: "password123"
    });
  };

  return <form onSubmit={handleSubmit}>{/* Your form elements */}</form>;
}

API Reference

SafeAction

Creates a new safe action with optional schema validation.

const actionClient = new SafeAction();
actionClient.schema(zodSchema).action((data) => Promise<Result>);

useAction

Hook to execute the safe action and manage its state.

const {
  execute, // Function to execute the action
  status,  // 'idle' | 'executing' | 'error' | 'success'
  loading, // boolean
  result, // returned result from the action
  reset    // Function to reset the state
} = useAction(action, {
  onSuccess?: (data: Result) => void,
  onError?: (error: {
    error: {
      validation: Record<string, string>,
      request: Record<string, string>
    },
    input: Input
  }) => void
});

Error Handling

react-zod-safe-action provides structured error handling for both validation and request errors:

{
  validation: { // Zod validation errors
    'field.path': 'error message'
  },
  request: {    // Other runtime errors
    'error_key': 'error message'
  }
}
