Simplified Form Handling with Actions in React 19

#Introduction

🚀 Simplified Form Handling with Actions in React 19 🎯 React 19 introduces Actions, a game-changing feature that makes form handling smoother by simplifying asynchronous operations like form submissions. This new approach eliminates unnecessary complexity, making your code cleaner and more efficient.

#Why Use Actions?

• ->Automatic State Management - Handles loading states, errors, and optimistic updates seamlessly.
• ->Declarative Approach - Pass functions directly to the action attribute in <form>, <input>, or <button>, reducing boilerplate.
• ->Improved Developer Experience - Write less code while achieving better form handling with fewer bugs.

#Code example of React 18

const NameFormReact18 = () => {
  const [name, setName] = useState("");
  const [isSubmitting, setIsSubmitting] = useState(false);
  const [error, setError] = useState(null);

  const handleChange = (e) => {
    setName(e.target.value);
  };

  const handleSubmit = async (e) => {
    e.preventDefault();
    setIsSubmitting(true);
    try {
      await apiCall(name);
    } catch (error) {
      setError(error);
    } finally {
      setIsSubmitting(false);
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <input type="text" value={name} onChange={handleChange} />
      <button type="submit" disabled={isSubmitting}>
        {isSubmitting ? "Submitting..." : "Submit"}
      </button>
      {error && <p>{error}</p>}
    </form>
  );
};

#Code example of React 19

const NameFormReact19 = () => {
  const [error, submitAction, isPending] = useActionState(
    async (prevState, formData) => {
      const name = formData.get("name");
      try {
        await apiCall(name);
        return null;
      } catch (error) {
        return "Failed to submit form";
      }
    },
    null
  );

  return (
    <form onSubmit={handleSubmit}>
      <input type="text" value={name} onChange={handleChange} />
      <button type="submit" disabled={isSubmitting}>
        {isSubmitting ? "Submitting..." : "Submit"}
      </button>
      {error && <p>{error}</p>}
    </form>
  );
};

With Actions in React 19, form handling becomes more intuitive, helping developers focus on building great user experiences with minimal effort. 🚀
