    Course Outline

    What Is Laravel?

    The simple answer to the question, ”what is Laravel?” is straightforward: Laravel is a cross-

     platform PHP framework for building web applications.

    But truly understanding the benefits of Laravel and its uses requires a deeper dive. Laravel

     allows a developer to take advantage of a large library of pre-programmed functionality

     (such as authentication, routing, and HTML templating). Access to this library makes it

    simpler to build robust web applications quickly while minimizing the amount of coding

     Necessary.

    Laravel offers a highly functional development environment, as well as intuitive and

    expressive command-line interfaces. In addition, Laravel uses an object-relational mapping

    (ORM) for simpler data access and manipulation.

    Laravel applications are highly scalable and have easy-to-maintain codebases. Developers

    Can also seamlessly add functionality to their applications, thanks to Laravel’s modular

    Packaging system and robust dependency management.

    Is Laravel Frontend or Backend?

    Is Laravel is primarily a backend development framework, though it does offer some frontend

    Functionality? Many of Laravel’s features, however, are frontend agnostic.

    Is Laravel a Programming Language?

    Laravel is a PHP framework and uses a scripting language rather than being a strict PHP

     programming language. While scripting languages and programming languages are related,

    they have several noticeable differences, primarily in ease of use and speed of execution.

     

    Scripting languages are platform-specific, interpreted languages. In contrast, programming

    languages are platform-agnostic, compiled languages. Being platform-specific, scripting

     languages rely on the compiler of the application in which they are working.

     

    Applications built using scripting languages are compiled at runtime, meaning that each

     instruction is interpreted individually at runtime, rendering the application slower than a pre-

    compiled application. Runtime compilation also results in the application stopping or

    shutting down if it encounters a runtime error; in contrast, pre-compiled applications

    perform error checking during compilation, making them more robust at runtime. For many

     users, though, the disadvantages of scripting languages are more than offset by their ease

     of use and iteration.

    What Is a PHP Framework?

     PHP (a recursive acronym for PHP Hypertext Preprocessor) is an open source, server-side

     scripting language widely used for web development. As of early 2021, nearly 80% of all

     websites are using PHP. While many may not be familiar with PHP, everyone is familiar with

     one of the most well-known PHP applications –  WordPress.

     

    A PHP framework provides a set of code libraries containing pre-programmed modules that

     allow a user to build applications faster. They offer web developers a number of benefits,

    including more rapid development, a reduced need to write code, and enhanced security.

     They also help novice developers build up good coding practices, since they require specific

    organization of code. What’s more, PHP frameworks typically require less maintenance than

     applications built from the ground up.

    Many modern PHP frameworks are object-oriented. Because of this, it’s beneficial to have a

    Basic understanding of concepts like classes, objects, and inheritance before diving into a

    Framework.

    PHP frameworks use a Model-View-Controller (MVC) architecture. For those unfamiliar with

     MVC architecture, the Model is the data for the application, along with all associated logic.

     A table of subscribers, for example, can be a Model. The View provides a point of interaction

     with a user, where data from the Model can be viewed and modified. The Controller is a

     conduit between the View and the Model. In other words, the Controller takes user requests,

     retrieves the requisite information from the Model, processes it, and returns it to the view.

     

    PHP applications, such as WordPress, have some known vulnerabilities. The most notable

     examples are code injection and SQL injection. Laravel includes features that help prevent

    SQL injection and other attacks.

     

    However, developers should undertake additional efforts, such as penetration testing, to

     ensure the security of their applications. According to IT expert Barbara Ericson of Cloud

     Defense, web application security consists of both penetration testing and web application

     firewalls, which go hand-in-hand.

     

    Penetration tests are intended to be more complex tests performed by qualified

     cybersecurity professionals, who will attempt to break into your system without any prior

     knowledge of its development in order to identify unpatched security vulnerabilities.

    Why Should You Use Laravel?

    Having answer “What is Laravel?” the next question is, “Why Laravel?” Laravel provides a

    Large set of robust tools that helps make the web app development process easier and

     Faster, and the final application codebases are well-structured and easily maintained.

    Some of the specific benefits of Laravel are:

     Laravel is Easy to Learn

    Laravel is relatively easy to learn, given the proper background. Laravel does require a

    general understanding of PHP and object-oriented programming (OOP) concepts for

     effective use. Knowing at least some HTML is helpful as well. And for any MVC architecture,

     it is also helpful to comprehend relational database management systems, such as MySQL

     or PostgreSQL.

     

    Laravel Simplifies the Development Process

    From the beginning, Laravel was designed to simplify tasks that are common across a

    variety of web development projects like routing, authentication, migration, caching, and

     more. Laravel makes it simple to integrate pre-made modules into an application, using

     intuitive and expressive command line interfaces and Composer.

    What Dose Laravel DO?

    Laravel’s feature set is far too extensive to cover fully in this brief overview. A few

    of the more significant features include:

    Route Handing

    Laravel provides straightforward and intuitive route handing, using simple to

    identify routes rather than long path names. The use of route identifiers also

    makes it easier to maintain applications, as the route name can be changed in

    one place rather than having to change it throughout. All web interface routes in

     a Laravel application are registered in the routes/web.php file.

     

    Security

    Laravel includes a number of security features including user authentication, user

    role authorizations, email verification, encryption services, password hashing, and

     password reset features.

     

    Migration

    Laravel provides version control for application databases using migrations.

    Migrations track how a database has been modified over time, making it easier to

    destroy or recreate the database when necessary.

     

    Templating

    Blade is Laravel’s PHP templating engine. PHP templating engines help divide

    business logic from HTML templating, resulting in a code base that is more easily

    maintained. Many of the features of Laravel rely on Blade templates. Blade offers

     more functionality than other templating engines because Blade allows use of

    plain PHP code, which others do not.

    Sessions

    Laravel uses sessions to store information about the user across several requests.

     Cookies are an example of a built-in Laravel session driver.

    Data Validation

    Laravel makes it simple to validate incoming user data. Laravel includes a number of data validation rule, with customizable error messages.

    Cache Handing

    Laravel supports data caching to minimize application task processing times

     Laravel’s cache API supports a variety of third-party cache backends such as

    Memcached and Redis.

    Error Handling

    Error handing is automatically configured upon starting a new Laravel project.

    Laravel applications can be run in debug mode, generating detailed error message

    for all errors that occur.

    Testing

    Laravel offers substantial testing figures out of the box. Laravel supports unit

     testing, which tests small, isolated sections of application code, as well as feature

     testing, which tests larger sections of code and higher-level functionality.

     

    Storage and File Management

    Laravel uses the Flysystem PHP package to provide drivers for working with a

    variety of filesystems, from local filesystems to cloud-based storage such as

    Amazon S3. Laravel also provides for file transfer with SSH File Transfer Protocol

     (SFTP).

    Email

    Laravel includes an email API based on the SwiftMailer library, which allows

    sending email through a service of choice. Laravel supports email attachments

     and email queuing.

    Notifications

    Laravel supports sending notifications over a number of channels, whether well-

    known channels such as SMS or Slack, or using channels developed by Laravel

    community.

    How Does Laravel Work?

    In order to best understand what Laravel can do, it is important to understand

    how Laravel deals with requests, i.e., the request lifecycle. As discussed above,

     Laravel is based on MVC architecture, and responds to requests from users,

    which the controller uses to retrieve and process data from the model and

     present information back to the user in a view.

     

    A request enters a Laravel application via the public/index.php file, which loads

    the rest of the framework and retrieves an instance of the Laravel application.

     After retrieval of the application instance, the request is routed to the console

     kernel or HTTP kernel.

     

    Among other tasks, the kernel defines a selection of bootstrappers that perform

    tasks that must be completed before request handling takes place, as well as

     defining any middleware that requests must pass through prior to handling.

     Among these pre-handling tasks is loading any service providers required for the application.

    Once bootstrapping is complete and service provide have been registered, the

     request passes to the router, which then directs the request to a route or to a

    controller.In  addition, the router runs any required router-specific middleware.

    after the request passes through all required middleware, execution of a router or

    controller method returns a response that passes back through the chain to the

    View.

    How Do You Get Started With Laravel?

    To being with Laravel, it is necessary to understand some of the most important

     structures and functionalities in Laravel.

    Service Containers

    The service container is one of the core components of Laravel. Services

    containers manage class dependencies and dependency injection.

     Service containers are where a developer binds everything necessary to run a

     Laravel application.

    Service Providers

    Equally important are Laravel service provides, which are where classes and

    dependencies are injected into the service containers.

    Facades

    Facades is a static interface for classes bound in the service container. Facades

    create ease of use by providing easily memorable syntax as a proxy for a long

    class name.

    Packages

    Packages are how functionality is added to Laravel. There are both stand-alone

    package and application-specific packages. Service providers tell Laravel where to

     load package resources.

    Command-Line Interfaces

    Laravel includes a set of command-line interface (CLIs).The Artisan Console

    includes commands that help developers quickly build skeleton code, simplify and

     automate repetitive tasks, and more easily complete an application build. Sail is a

    lighter-weight command-line interface introduced in Laravel 8.Sail lets the

    developer interact with Docker,Laravel’s default development environment.

    Eloquent

    Eloquent is an object-relational mapper (ORM) that allows easy interaction with

     databases.Using the MVC architecture, the models correspond to individual

    tables in a database. With Eloquent, developers can be assured of quick retrieval,

     simple insertions and updates, and intuitive definition of relationships.

    Composer

    Composer is a third-party application-level PHP dependency management tool.

     Composer manages the libraries, modules, and plug-ins required by a Laravel

     application.

    Homestead

    Laravel Homestead is a development environment allowing development on

    avirtual machine by providing a pre- packaged Vagrant box. Homestead includes

    everything needed for Laravel application development, including PHP, MySQL

    Nginx, Composer, Redis, and much more, so the developer need not install these

    packages on their local machine. Homestead does require the installation of

     Vagrant and either VirtualBox or Parallels.

    Authentication Starter Kits

    Laravel includes a number of packages to help get developers up and running

    quickly. Prior to diving in, you may wish to review some of the many available

    resources for learning Laravel. Laravel includes a couple of starter kits to help the

    developer implement common functionality quickly.

    Laravel Breeze is an authentication starter kit. IT includes common authentication

    and user account features such as user registration, login, email verification, and

    password confirmation and reset. Breeze also includes a javascript frontend

    through Vue.Breeze has a default view layer that uses Blade templates and

    Tailwind CSS.

    For more advanced authentication features, Laravel now offers Jetstream, first

    introduced in Version 8. In addition to the features found in Breeze, Jetstream

     also offers additional advanced feature such as two-factor authentication,

    session management, API support via

    Laravel Sanctum, and optional team management.

    For developers that prefer to use their own authentication frontend, Laravel

    offers Fortify—an authentication backend that is frontend agnostic. Fortify is the

     engine for the Jetstream authentication starter kit and includes all of the Laravel

    authentication features (e.g. user registration, login, email verification, two-factor

     authentication, etc.). Fortify is not the underlying engine for Laravel Breeze.

     

    Laravel also offers social media-based authentication (OAuth) through Laravel

     Socialite.

     

    For developers who want to deploy their applications with minimal server

     configuration or, indeed, want serverless deployment, Laravel offers Forge and

    Vapor. Forge allows for deployment through a variety of infrastructure providers

    with minimal configuration efforts. Vapor is a serverless deployment platform

    based on AWS.

     

    For those looking to take the next step, developers can deploy their Laravel

    applications through their own self-hosted website. This is because self-hosting

    your website will require you to set up several defined databases with a single

    PHP command (using the latest version) and SSH access to the server. Laravel

    offers both in one open-sourced PHP framework, and as an added bonus, it’s

    quite easy to install.

     

    What Else Can Laravel Do?

    The better question might be, “What can’t Laravel do?” Thousands of packages

    exist that accomplish any number of functions. Some of the more interesting

    official Laravel packages are:

     

    Cashier and Spark

    Laravel Cashier provides an interface for subscription billing services from Stripe

    and Paddle. Cashier also provides advanced subscription functionality, such as

    coupons and cancellation grace periods.

     

    Cashier is the engine for Laravel Spark, a billing management panel that allows

    users to create and manage their subscriptions. Spark is also limited to Stripe and

    Paddle as payment providers; custom providers are not yet compatible with

     Spark. Spark does, however, allow the developer to choose their frontend.

     

    Valet

    Laravel Valet is a macOS development environment focused on speed and

    minimal resource usage (around 7 MB of RAM). Valet is not intended to be a

    complete replacement for Sail or Homestead. Instead, it’s meant for users with

    specific needs and resource limitations.

     

    For more packages, see the Laravel website or Packalyst.

     

    Laravel in 2021

    The current version of Laravel is version 8, initially released in September 2020.

    This version includes a number of new features and improvements. Some of the

    new features in version 8 include Laravel Jetstream, job batching (allows

    execution of a batch of jobs, followed by performance of defined actions),

    Dynamic Blade components (allows runtime component rendering based on a

    runtime value), and use of Tailwind CSS by default in the Laravel paginator,

    among others. Improvements were also made to rate limiting and maintenance

    mode.

     

    Take note that Laravel issues a new major release every year in September, with

    minor releases issuing as needed. Laravel version 9 is currently scheduled for

    release in September 2021.

     Summary                                                                                                                                                                                  Developers seeking fast and simple web application development should consider

     learning Laravel. Laravel provides an extensive and robust set of resources that

     simplifies the development process by eliminating the need to code many

    common tasks from scratch.

     

    Laravel also provides a secure virtual development environment and intuitive

     command-line interfaces. And because Laravel is simple to learn and has a strong

    support community and ecosystem, it’s a natural choice for many developers, be

     they beginners or experts with years of experience.

    Save times, costs and maximize site performance with:

    All of that and much more, in one plan with no long-term contracts, assisted

    migrations, and a 30-day-mony-back-guarantee. Check out our plans or talk to

    sales to find the plan that’s right for you.
