Error tracking is an essential part of modern software development, enabling developers to identify and resolve issues that may impact the performance and reliability of their applications. Laravel, a widely used PHP framework, provides a robust platform for building web applications, but like any other software, it can encounter errors during development and production. 

When an application is in production, errors can significantly impact user experience, resulting in loss of revenue, decreased customer satisfaction, and reputational damage. To effectively track and resolve errors in Laravel applications, developers need a reliable and comprehensive error-tracking solution that can provide real-time notifications and insights into the root causes of errors.  Sentry, a powerful error-tracking tool, offers an array of features designed to simplify error management, enabling developers to quickly identify, diagnose, and resolve errors, regardless of whether the application is in development or production.

In this article, we will delve into the process of configuring Sentry for error tracking in Laravel, empowering developers to proactively monitor and resolve errors, ensure a seamless user experience, and deliver reliable and high-performing software.


## Prerequisites


- Basic knowledge of PHP and the Laravel framework.
- A Sentry account. Open a free account [here](https://sentry.io/signup/).
- Composer: Composer is the dependency manager for the PHP programming language that provides a standard format for managing dependencies of PHP software and required libraries. We’ll use it to install some packages in the project directory. Download it [here](https://getcomposer.org/download/).
## Getting Started 

First, we create a new Laravel project by running the command below in the terminal.

```php
    laravel new sentry-laravel
```


## Sentry Setup

Here’s how to set up Sentry


1. Access the Sentry [dashboard](https://self-uz2.sentry.io/projects/) and navigate to the Projects tab.
![Sentry dashboard](https://paper-attachments.dropboxusercontent.com/s_28375E65E1F5892C9FE175262123A7F1D7E3CFF757A38F124FC981D13428FC39_1682517479191_Screen+Shot+2023-04-26+at+2.57.45+PM.png)

1. Click on "Create Project" to start the project creation process.
2. Choose Laravel as the platform for your project.
3. Optionally, rename the project to your desired name.
4. Keep the other settings as they are and click on "Create Project" to create your project.

We continue the setup by installing the [**sentry-laravel**](https://github.com/getsentry/sentry-laravel) package. We can do that by running the command below.

```php
    composer require sentry/sentry-laravel
```
This command installs the **sentry-laravel** Software Development Kit(SDK). Once installed and configured, the package sends error and exception events that occur within your Laravel application to Sentry.

Next, we go to the **App/Exceptions/Handler.php** directory in our Laravel projects and add the following code block to the **register** function.
```php

    use Sentry\Laravel\Integration;
    
    public function register()
    {
        $this->reportable(function (Throwable $e) {
            if (app()->bound('sentry')) {
                app('sentry')->captureException($e);
            }
        });
    }
```
In the code block above,  we are defining a custom exception-handling function in our Laravel application, which will capture any unhandled exceptions and send them to Sentry using the `app('sentry')->captureException($e)` method. The `if (app()->bound('sentry'))` check ensures that the Sentry service is available and registered in the application before trying to capture the exception.
 
We need to create a Sentry configuration file in Laravel to customize our error-tracking settings. This can be done by running the command below.

```php
    php artisan sentry:publish --dsn=<your-dsn>
```
This command creates a file called `**sentry.php**` in the `**config**` directory of our Laravel project. It also adds the **DSN** to our `**.env**` file which allows Laravel to send error data to Sentry for real-time tracking.

Remember to replace `<your-dsn>` with your own DSN.

Finally, let's send a test exception to Sentry. We can do that by running the command below

```php
    php artisan sentry:test

```

If everything is set up correctly, we should be able to see the response below in the Issues tab.

## 
## Testing Sentry with Code

To confirm that Sentry is capturing errors in our application, we will create a route that throws an exception.

Open the `**routes/web.php**` ****and add the following code snippet.
```php

    Route::get('/test-sentry', function () {
        throw new Exception('Testing Sentry...');
    });
```

The response below should be displayed.



## Conclusion

With Sentry's robust features and intuitive dashboard, developers can proactively monitor their Laravel applications, gain insights into error trends, and ensure smooth operation. By incorporating Sentry into their error management workflow, developers can streamline their debugging process, save time, and deliver high-quality software.
