What is Laravel?
Laravel is a free, open-source PHP web application framework, designed for the development of model–view–controller (MVC) web applications.
Laravel is released under the MIT License, with its source code hosted on GitHub.
It is a web application framework with expressive, elegant syntax.
It attempts to take the pain out of development by easing common tasks used in the majority of web projects, such as authentication, routing, sessions, queueing, and caching.
It is accessible, yet powerful, providing powerful tools needed for large, robust applications. A superb inversion of control container, expressive migration system, and tightly integrated unit testing support give you the tools you need to build any application with which you are tasked.
Why Use Laravel?
Easy and consistent syntax, great design patterns used for the framework core development, teaches you how to be a better developer, composer package manager, incredibly great and positive community, almost perfect documentation.
Laravel is the Most starred PHP Framework in GitHub and Top trending framework now. It simplifies everything. So, PHP Developers don’t need to break the head for everything.
Laravel Directory Structure:
The Root Directory
The root directory of a fresh Laravel installation contains a variety of folders:
The app
directory, as you might expect, contains the core code of your application. We’ll explore this folder in more detail soon.
The bootstrap
folder contains a few files that bootstrap the framework and configure autoloading.
The config
directory, as the name implies, contains all of your application’s configuration files.
The database
folder contains your database migration and seeds.
The public
the directory contains the front controller and your assets (images, JavaScript, CSS, etc.).
The resources
the directory contains your views, raw assets (LESS, SASS, CoffeeScript), and “language” files.
The storage
the directory contains compiled Blade templates, file based sessions, file caches, and other files generated by the framework.
The tests
the directory contains your automated tests.
The vendor
the directory contains your Composer dependencies.
The App Directory
The “meat” of your application lives in the app
directory. By default, this directory is namespaced under App
and is autoloaded by Composer using the PSR-4 autoloading standard. You may change this namespace using the app:name
Artisan command.
The app
directory ships with a variety of additional directories such as Console
, Http
, and Providers
. Think of the Console
and Http
directories as providing an API into the “core” of your application. The HTTP protocol and CLI are both mechanisms to interact with your application but do not actually contain application logic. In other words, they are simply two ways of issuing commands to your application. The Console
directory contains all of your Artisan commands, while the Http
directory contains your controllers, filters, and requests.
The Jobs
directory, of course, houses the queue jobs for your application. Jobs may be queued by your application, as well as be run synchronously within the current request lifecycle.
The Events
directory, as you might expect, houses event classes. Of course, using classes to represent events is not required; however, if you choose to use them, this directory is the default location they will be created by the Artisan command line.
The Listeners
the directory contains the handler classes for your events. Handlers receive an event and perform logic in response to the event being fired.
The Exceptions
the directory contains your application’s exception handler and is also a good place to stick any exceptions thrown by your application.
Features of Laravel Framework:
- Routing system: This framework takes an incredibly simple and easy-to-use approach to routing. Most beginner PHP developers aren’t familiar with anything other than the most natural of route systems. It brings more flexibility and control over which route is triggered on the application. A directory is created to match any desired URI. For example, an index.php file is added to the following directory: blog/admin/ and now can be accessed by browsing to: localhost:8888/blog/admin/index.php. It allows creating links to named routes. While creating links just use the route’s name and Laravel will automatically insert the correct URI. This allows to change routes at a later time and it will update all of the relevant links site-wide.
- Unit-Testing: It is an important part of the Laravel framework. It runs hundreds of tests to ensure that new changes don’t unexpectedly break anything. Laravel is widely considered to have some of the most stable releases in the industry as it is cautious of the known failures. Slowly it is being liked by the developers. It also makes it easy to write unit tests for your own code. One can then run tests with the “Artisan” command-line utility.
- View Composers: These are blocks of code that can be run when a view is loaded. A very good example of this would be a blog side-navigation where it contains a list of random blog posts. A composer would contain the logic to load the blog posts so that all one has to do is load the view. This keeps from having to make sure that controllers load a bunch of data from models for views that are unrelated to that method’s page content.
- Application Logic: It can be implemented within any application either using controllers or directly into route declarations using syntax similar to the Sinatra framework. Laravel is designed with privileges giving a developer the flexibility that they need to create everything from very small sites to massive enterprise applications.
- Automatic Pagination: It prevents application logic from being cluttered up with a bunch of pagination configurations. It gets the count of db records and selected data using a limit/offset called ‘paginate’ and interacts with Laravel where to output the paging links in view. Laravel’s pagination system was designed for programmers to make their work easier to implement and change. Laravel can handle these things automatically and makes tasks easier.
Advantages:
- The large community behind it, providing support and components that can be used with it.
- Frameworks like Laravel that are open source and have large communities are usually written well, and quite secure as a result. Basically, you alone will probably not write code as well as the hundreds of people that have contributed to a framework like Laravel.
- Code is kept organized, and using a framework like Laravel helps enforce some best practices.
- If you’re using a framework you don’t have to write all of that code for the standard features yourself every time.
- They’re usually well optimized too, otherwise, they wouldn’t be used!
- Frameworks come with a lot of features built-in that help you out, like template engines, dependency injection containers, service layers, and well-structured code.
