Understanding Laravel Sanctum: Do You Need to Call the CSRF Cookie on Every Request?

When working with Laravel Sanctum, an authentication system for single-page applications (SPAs), developers often encounter questions about CSRF (Cross-Site Request Forgery) protection and how to manage cookies effectively. A common question arises: Do I need to call the /sanctum/csrf-cookie route with every request? In this guide, we’ll break down how to handle CSRF cookies in Laravel Sanctum, helping you streamline your API requests without compromising security.

The Problem: Managing CSRF Cookies with Laravel Sanctum

When authenticating your SPA, the Laravel documentation advises making a call to the /sanctum/csrf-cookie route to initialize CSRF protection before any authentication attempts. This raises a few concerns:

Repeated Requests: Should you make the CSRF cookie request every single time before API calls, especially for "POST", "PUT", or "DELETE" requests?

User Experience: How does the workflow impact user experience, especially when users need to register and then log in immediately after?

These concerns are valid and crucial for ensuring that users have a smooth experience while maintaining security.

The Solution: Efficiently Handling the CSRF Cookie

1. Understanding the CSRF Cookie Behavior

You do not need to call the /sanctum/csrf-cookie route before every request. Instead, you can check if the XSRF-TOKEN cookie is set before making any sensitive requests. Here’s how the process works:

First, make a check for the presence of the XSRF-TOKEN cookie.

If it is present, you can safely make your request without calling the cookie route again.

If the cookie is not present, then proceed to call the /sanctum/csrf-cookie route to set it.

2. Using Axios Interceptors

To optimize this process, consider using Axios interceptors. Interceptors allow you to define custom logic before your requests are sent. Here’s a step-by-step guide:

Install Cookie Management Library:
You can use js-cookie for cookie management. Install it via npm:

3. User Registration and Login Flow

Another point of confusion arises when users complete their registration but aren't logged in immediately. This can be improved as follows:

Redirection after Registration: After users register, rather than immediately redirecting them to the login page, consider using a prompt or modal that alerts them to check their email for verification or logs them in automatically if verification isn’t needed. This can enhance the user experience.

Conclusion

By understanding how Laravel Sanctum handles CSRF cookies, you can significantly simplify your API interactions without compromising security. Remember, there’s no need to call /sanctum/csrf-cookie for every request.
Instead, check for the XSRF-TOKEN cookie, and utilize Axios interceptors to manage it seamlessly. With these practices in place, you create a more efficient and user-friendly application.
