Laravel Programming Tutorials, Guides & Best Practices

• Multiple users submit forms simultaneously, and their data is processed by queued jobs.
• Two jobs attempt to update the same resource, such as inventory or account balances, at the same time.
• A lack of locking or proper checks causes overwrites, duplicate entries, or data corruption.

We’ll address these issues with practical solutions.

The N+1 query problem happens when your application executes one query to retrieve a parent dataset, followed by multiple additional queries to fetch related data for each parent record.

Imagine you want to fetch a list of posts along with their authors:

• Define API limits: A dynamic configuration for API request limits.
• Load Global Preferences: Preferences like application mode (e.g., maintenance or live).
• Control Features: Toggle features dynamically, such as enabling/disabling a user feedback form.

We will use a service provider to load this data and make it available throughout the application.

Laravel’s service container provides a simple way to implement the singleton pattern.

   php artisan make:provider SharedDataServiceProvider
