Laravel interview questions and answers

1.

What are Laravel events?


This is one of the most common Laravel job interview questions. An event is a happening or incident that the program detects and handles. A Laravel event provides a straightforward observer pattern implementation, allowing you to subscribe to and listen for events in your application.

Here are some examples of events in Laravel:

  • A new user has joined the site
  • A new comment has been added
  • Login/logout of users
  • A new product has been added

2.

What do you know about the Laravel query builder?


You will often come across this Laravel framework interview question. The database query builder in Laravel provides an easy-to-use interface for creating and running database queries. It can be used in your application to perform most database operations and works with all supported database systems.

To protect your application from SQL injection attacks, the Laravel query builder employs PDO parameter binding. The strings passed as bindings do not need to be cleaned.

Some QB features:

  • Chunking
  • Joins
  • Unions
  • Where
  • Ordering, Grouping, Limit, & Offset
  • Aggregates
  • Selects
  • Raw Expressions

4.

What is Laravel Middleware?


This is one of the most asked Laravel job interview questions. In Laravel, middleware acts as a bridge between the request and the response. It provides a mechanism for investigating HTTP requests that come into your application. For example, in Laravel, middleware ensures that the user of your specific application is authenticated. If they discover that the user is not authenticated, they will redirect the user to the application's primary login page.

5.

What is database migration?


Database migration is similar to database version control in that it allows the team to modify and share the application's database schema. Database migrations are used in conjunction with Laravel's schema builder, which is used to create the application's database schema.

6.

What are service providers?


This is a commonly asked Laravel framework interview question. Service providers are the center for bootstrapping or configuring your Laravel applications. Laravel's core services are all bootstrapped via service providers.

Developers use service providers to monitor class dependencies and conduct dependency injection.

7.

What available databases does Laravel support?


Laravel supports the following available databases:

  • PostgreSQL
  • MySQL
  • SQL Server
  • SQLite

8.

Can Laravel be used for Full Stack Development (Frontend + Backend)?


Laravel is the best choice for creating progressive, scalable full-stack web applications. Full-stack web applications can have a backend written in Laravel and a frontend built with blade files or SPAs built with Vue.js, which is included by default. However, you can also use it simply to provide rest APIs to an SPA application. As a result, Laravel can be used to create full-stack applications and just backend APIs.

9.

What is dependency Injection?


It is common to come across this Laravel framework interview question. The Laravel Service Container, also known as the IoC, resolves all dependencies in all controllers. As a result, any dependency in controller methods or constructors can be type-hinted. The dependencies in methods will be resolved and injected into the method; this injection of resolved classes is referred to as dependency injection.

10.

What is the use of dd() in Laravel?


It is a helper function that is used to dump the contents of a variable to the browser and halt further script execution. It is an abbreviation for Dump and Die.
