How to use Inertia.js Forms & The Inertia.js Form Helper

By /

In the realm of web development, Inertia.js continues to redefine the landscape by seamlessly fusing server-side rendering with client-side interactivity. Recently, the Inertia.js ecosystem welcomed a robust addition: Inertia.js Forms and the Form Helper. In this technical exploration, we’ll dive deep into Inertia.js Forms and dissect the Form Helper with practical code examples, revealing how they can revolutionize your development workflow.

The Power of Inertia.js

Inertia.js is highly regarded for its unique approach to unifying server-side rendering with client-side interactivity. Its compatibility with prominent back-end frameworks such as Laravel and Rails has made it a top choice among developers.

Unmasking Inertia.js Forms

Inertia.js Forms, an official package extending the Inertia.js feature set, introduces a seamless way to manage forms within your Inertia.js application. This allows you to uphold traditional server-side form handling while capitalizing on the potential of single-page applications.

In-Depth with the Inertia.js Form Helper

At the core of Inertia.js Forms lies the Form Helper, a powerhouse that simplifies form management within your Inertia.js application. Let’s break down its features with code examples:

1. Form Creation:

To craft a form, use the inertia.form method in your views, specifying the form’s action and data.

// In your Vue component
const form = inertia.form({
    action: '/submit',
    data: {
        name: '',
        email: '',
    },
});

2. Validation Handling:

The Form Helper eases form validation, automating the handling of validation errors and old input data.

// Handling form submission and validation
form.post().then(response => {
    // Handle success
}).catch(error => {
    // Handle validation errors
    form.errors = error.response.data.errors;
});

3. Submission Handling:

Maintain precise control over post-submission processes.

// Handling form submission and redirection
form.post().then(response => {
    // Handle success
    window.location = '/success';
});

4. Flash Messages:

Display success or error messages with ease.

// Handling form submission and flash messages
form.post().then(response => {
    // Handle success and flash a message
    flash('Form submitted successfully');
}).catch(error => {
    // Handle validation errors and flash an error message
    flash('Form submission failed', 'error');
});

5. CSRF Protection:

The Form Helper ensures security by automatically adding CSRF protection to your forms.

<!-- In your form -->
<form method="POST" action="/submit" @submit.prevent="form.submit">

    <!-- Form fields here -->
    
</form>

Getting Started: A Code-Driven Journey

Embarking on your Inertia.js Forms adventure is straightforward. Begin by installing the package and gradually transition from traditional server-side forms to the Inertia.js Forms paradigm, with your codebase remaining accessible.
