How to Make Ajax Request In Laravel?

6 minutes read

To make an AJAX request in Laravel, you can use the built-in Axios library which is already included in Laravel by default.

First, create a route in your web.php file that will handle the AJAX request. Next, create a controller method that will return the response for the AJAX request.

In your Blade view file, use JavaScript to make the AJAX request using Axios. In the JavaScript code, specify the URL of the route you created and also include any data that needs to be sent along with the request.

Once the AJAX request is made, you can handle the response in the then() method of the Axios call. You can then update your view with the data received from the AJAX request.

Remember to include CSRF token in your AJAX request in order to prevent CSRF attacks. You can do this by adding a meta tag in your main layout file or by passing the token as a header in the AJAX request.

By following these steps, you can successfully make an AJAX request in Laravel and handle the response accordingly.

What is the impact of AJAX requests on server performance in Laravel?

AJAX requests can have a significant impact on server performance in Laravel, as they often result in additional server-side processing and resource consumption. When handling AJAX requests, the Laravel server has to process the request, retrieve data from a database (if necessary), send a response back to the client, and potentially perform other operations as well.

If not managed properly, a high volume of AJAX requests can put a strain on the server, leading to slower response times, decreased performance, and potential server overload. To mitigate these issues and improve server performance when handling AJAX requests in Laravel, developers can implement techniques such as caching, optimizing database queries, using efficient code, and leveraging server-side technologies like queues and load balancing.

How to implement AJAX polling in Laravel?

To implement AJAX polling in Laravel, you can follow these steps:

  1. Create a new route in your web.php file to handle the AJAX request:
Route::get('polling', 'PollingController@polling');

  1. Create a new controller called PollingController:
php artisan make:controller PollingController

  1. Define the polling method in the PollingController to handle the AJAX request:
public function polling()
    $data = // retrieve the data you want to return to the client
    return response()->json($data);

  1. Create a new JavaScript file to handle the AJAX polling:
$(document).ready(function() {
    setInterval(function() {
            url: '/polling',
            type: 'GET',
            success: function(response) {
                // handle the response data
            error: function(xhr, status, error) {
    }, 5000); // Poll every 5 seconds

  1. Include the JavaScript file in your blade file:
<script src="{{ asset('js/polling.js') }}"></script>

  1. Make sure to update the URL in the AJAX request to match the route you created in step 1.

Now, your Laravel application will poll the server every 5 seconds using AJAX and update the data on the client-side as needed.

What is the difference between sync and async AJAX requests in Laravel?

In Laravel, synchronous (sync) and asynchronous (async) AJAX requests refer to how the client-side JavaScript code interacts with the server-side PHP code.

  1. Synchronous AJAX requests:
  • In a synchronous AJAX request, the client-side JavaScript code sends a request to the server and waits for a response before continuing to execute any other code.
  • This means that while the AJAX request is processing, the user interface may become unresponsive or frozen until the request is complete.
  • Synchronous requests are blocking in nature, meaning that the user cannot perform any other actions while the request is being processed.
  • To make a synchronous AJAX request in Laravel, you can use the $.ajax() method with the async: false option.
  1. Asynchronous AJAX requests:
  • In an asynchronous AJAX request, the client-side JavaScript code sends a request to the server but does not wait for a response before continuing to execute other code.
  • This allows the user interface to remain responsive and interactive while the request is being processed in the background.
  • Asynchronous requests are non-blocking, meaning that the user can continue to interact with the page while the request is ongoing.
  • To make an asynchronous AJAX request in Laravel, you can use the $.ajax() method without specifying the async option (or setting it to true, which is the default behavior).

In general, asynchronous AJAX requests are preferred over synchronous requests in web development, as they provide a better user experience by allowing the page to remain responsive and prevent any potential freezes or delays.

What is the difference between AJAX and Axios in Laravel?

AJAX is a web development technique for creating interactive web applications by sending and receiving data asynchronously using JavaScript and XMLHttpRequest. It is a client-side technology that makes HTTP requests to the server without re-loading the entire page.

Axios, on the other hand, is a popular JavaScript library that is used to make HTTP requests from the client-side to the server-side in a more efficient and user-friendly way. It is specifically designed for making HTTP requests in a simple and easy way, allowing developers to handle responses more effectively.

In the context of Laravel, AJAX can be used to make HTTP requests to the server in a raw form, while Axios can be used to simplify and streamline the process of making HTTP requests. Axios provides a cleaner and more organized way to handle HTTP requests, with built-in features such as request and response interception, error handling, and more.

Overall, the main difference between AJAX and Axios in Laravel is that AJAX is a general technique for making asynchronous HTTP requests, while Axios is a specific library that simplifies and enhances the process of making HTTP requests in a client-side application.

How to debug AJAX requests in Laravel?

To debug AJAX requests in Laravel, you can follow the steps below:

  1. Enable debugging in your Laravel application by setting the APP_DEBUG variable to true in your .env file.
  2. Use the dd() function to dump and die at specific points in your code to see the output of your AJAX requests. This function will display the data in a formatted way that is easier to read.
  3. Utilize Laravel's built-in logging functionality to keep track of AJAX requests. You can use the Log facade to create logs with different levels of severity (e.g., info, warning, error).
  4. Use browser developer tools to monitor and inspect AJAX requests. You can use the Network tab in Chrome or the Network panel in Firefox to see the details of AJAX requests, including the URL, request method, response status, and response content.
  5. Install the Laravel Debugbar package to get more detailed information about your AJAX requests, including SQL queries, request data, and response data.

By following these steps, you can effectively debug AJAX requests in Laravel and troubleshoot any issues that may arise.

What is the role of CSRF tokens in AJAX requests in Laravel?

CSRF (Cross-Site Request Forgery) tokens play an important role in ensuring the security of AJAX requests in Laravel. When using AJAX requests to make changes to data on a web application, there is a risk of a malicious website executing requests on the user's behalf without their consent.

CSRF tokens are used to prevent this type of attack by providing a unique token with each request that must be included in the request headers. Laravel automatically includes a CSRF token in every outgoing AJAX request, and checks that the token matches the one stored in the user's session when the request is received. If the tokens do not match, the request is considered invalid and will be blocked.

By using CSRF tokens in AJAX requests, Laravel helps to protect against unauthorized cross-site request forgery attacks and maintain the integrity of the web application's data.
