Supervisor is a process control system for Linux that allows you to monitor and control processes on your server. It is particularly useful for managing long-running processes, such as Laravel queues, which can run for hours or even days at a time. In this post, we will go through the process of installing and using Supervisor with Laravel queue
The Adapter pattern is a structural design pattern that allows two incompatible interfaces to work together. This pattern is used to create a bridge between two incompatible interfaces by creating an intermediate adapter that can translate the interface of one object to another. The Adapter pattern is useful when you need to use an existing class, but its interface doesn’t match the one you need.
The Decorator Design Pattern is a design pattern that is used to extend the behavior of an object dynamically, without changing its class. It is a structural pattern that can be used to add responsibilities to individual objects, instead of creating a new subclass.
The strategy design pattern is a behavioral design pattern that allows an object to change its behavior based on a given context. The pattern involves separating an object’s behavior into different strategies and allowing the object to switch between these strategies at runtime. This allows for greater flexibility and maintainability in the code, as the behavior of the object can be changed without modifying the object itself.
The Abstract Factory pattern is a design pattern that provides an interface for creating families of related or dependent objects without specifying their concrete classes. It allows for the creation of objects that follow a certain pattern, without the need to specify the exact class of the object to be created.
Sometimes individual processes take a long time to complete, such as sending email, payment gateway, etc. When you send an email for verification, it takes time. If you don’t want to make the user wait, then you need to use queues. This will make your service fast for the user.
Laravel Events provides a simple implementation of the Observer pattern, allowing you to subscribe to and monitor various events that occur in your application. Event classes are usually stored in the app/Events directory and their listeners in app/Listeners.
In web development, data integrity and accuracy are important. Therefore, we need to be sure that we are writing code that securely stores, updates, and deletes data in our databases. In this article, we’ll take a look at what database transactions are, why they’re important, and how to get started using them in Laravel. We will also look at typical problems associated with third-party services and database transactions.
Repositories are classes or components that contain the logic needed to access data sources. Repositories provide centralized functionality for accessing data, allowing better management and separation of the infrastructure or technology used to access data from the domain model. If you’re using an object-relational mapping (ORM) like the Laravel Framework, the code you need to implement is simplified thanks to Eloquent and strong typing. This allows you to focus on the data persistence logic rather than the data access helper functions.
PHP 5 introduced us to a new error model that is still evolving today. This model allows you to throw and catch exceptions in your application - it’s a better way to handle errors than older versions of PHP. All exceptions are instances of the Exception base class, which we can extend to introduce our own custom exceptions.
