Laravel Nova- To increase your productivity

It is a uniquely designed, sleek-looking single-page application. Laravel developers have designed this administration panel. Besides, with simple PHP coding, the Nova dashboard is configurable.

The most notable things of Nova are-

Resource Management– A CRUD interface of Nova is best for Eloquent models. Nova works with different Eloquent relationships, and also you may adjust the polymorphic data.

Actions– They refer to PHP tasks, running against resources. Also, there are queued actions on the Nova dashboard.

Filters– For resource indexes, you can compose custom filters to let users have a view at different data segments. You may also use the integrated filters.

Lenses– You may think of having more customizations for the resource list. Thus, insert lenses to the resource to control the Eloquent query.

Metrics– Laravel Nova has simplified the process of displaying custom metrics for the application. You can create graphs of different types within a few seconds.

Authorization– The current authorization policies of Laravel integrate Nova. Moreover, Nova resources help in leveraging your application policies to identify the user’s abilities.

Custom Fields– Rely on the Nova CLI to find a field type, not originally present in Nova. Hence, you can design and implement this field very easily.

Laravel Horizon- Best queue manager

When you have chosen the Laravel environment for projects, you may rely on Horizon for queue management. The overall configuration is very easy, and it gives you control over Redis queues. Besides, it is one of the Laravel tools helping professional developers to monitor and configure the queue processing.

For Free consultation or demo

Laravel is the most happening framework these days. Some of its great features are the intuitiveness, speed, scalability, and high cost-effectiveness. As per the survey report by Enlyft, Laravel is most popular in the United States. The Laravel ecosystem provides powerful security features, such as checking active users, BCrypt hashing, password reset, and encryption, within the framework.

Laravel is a simple yet robust model-view-controller (MVC) framework created for PHP web application development. It became one of the most popular PHP framework thanks to the rich set of functionalities that optimize the development process. Laravel environment facilitates fast development cycles and so delivers the business value relatively quickly. The Laravel brand offers two development environments, one runs locally on your Machine and one is a pre-packaged Vagrant box that has virtually everything you need.

Development Environment:

Laravel Valet configures the Mac to always run Nginx in the background when the machine starts. Then, using DnsMasq, Valet proxies all requests on the *. test domain to point to sites installed on the local machine.

Laravel Homestead is the official Laravel development environment. Powered by Vagrant, Homestead gets your entire team on the same page with the latest PHP, MySQL, Postgres, Redis, and more.

Packages and tools:

Laravel Passport is native OAuth 2 server for Laravel apps. Like Cashier and Scout, you’ll bring it into your app with Composer. It uses the League OAuth2 Server package as a dependency but provides a simple, easy-to-learn and easy-to-implement syntax.

Laravel Scout provides a simple, driver-based solution for adding a full-text search to the Eloquent models. Using model observers, Scout will automatically keep the search indexes in sync with the Eloquent records.

Laravel Dusk provides an expressive, easy-to-use browser automation and testing API. Dusk is an end-to-end browser testing tool for JavaScript enabled applications. It can work with any Selenium browser, but it comes with ChromeDriver by default which will save you from installing JDK or Selenium.

Laravel Socialite provides an expressive, fluent interface to OAuth authentication with Facebook, Twitter, Google, LinkedIn, GitHub, GitLab, and Bitbucket.

Laravel Echo is a JavaScript library that makes it painless to subscribe to channels and listen for events broadcast by Laravel. Laravel Echo is a tool that makes it easy for you to bring the power of WebSockets to your Laravel applications.

Laravel Mix is a tool for compiling and optimizing assets in a Laravel app. It’s similar to a build tool like gulp, Grunt and such like. it’s specific to Laravel but can also be used externally as an npm package. Laravel Mix covered 80% of Webpack’s use case to make compiling assets easier.

Laravel Cashier provides an expressive, fluent interface to Stripe’s and Braintree’s subscription billing services. In addition to basic subscription management, Cashier can handle coupons, swapping subscription, subscription “quantities”, cancellation grace periods, and even generate invoice PDFs.

Laravel Envoy provides you a simple and elegant way to run common tasks on your remote servers. If you have ever used Fabric, Capistrano or other tools for managing remote tasks, you already have an idea of how Envoy tasks will look like.

Paid tools and services:

Laravel Forge is a tool for deploying and configuring web applications. It was developed by the makers of the Laravel framework, but it can be used to automate the deployment of any web application that uses a PHP server.

Laravel Envoyer is a zero-downtime deployer for PHP & Laravel projects, which means it is a tool that you connect to your server to run your deploys, and which uses a series of tools to ensure that all of the preparation work each deploy needs in order to run.

Laravel Spark is designed with only one goal in mind, to make scaffolding out a billing system for a SaaS app easy. It features team management, user roles, recurring billing through Stripe, and much more.

Writing Custom Laravel Artisan Commands

Laravel Tutorials / August 08, 2017

Writing Custom Laravel Artisan Commands

I’ve written console commands in many different languages, including Node.js, Golang, PHP, and straight up bash. In my experience, the Symfony console component is one of the best-built console libraries in existence—in any language.

Laravel’s artisan command line interface (CLI) extends Symfony’s Console component, with some added conveniences and shortcuts. Follow along if you want to learn how to create some kick-butt custom commands for your Laravel applications.

Overview

Laravel ships with a bunch of commands that aim to make your life as a developer easier. From generating models, controllers, middleware, test cases, and many other types of files for the framework.

The base Laravel framework Command extends the Symfony Command class.

Without Laravel’s console features, creating a Symfony console project is pretty straightforward:

#!/usr/bin/env php <?php // application.php require __DIR__.'/vendor/autoload.php'; use Symfony\Component\Console\Application; $application = new Application(); // ... register commands $application->add(new GenerateAdminCommand()); $application->run();

You would benefit from going through the Symfony console component documentation, specifically creating a command. The Symfony console component handles all the pain of defining your CLI arguments, options, output, questions, prompts, and helpful information.

Laravel is getting base functionality from the console component, and extends a beautiful abstraction layer that makes the building consoles even more convenient.

Combine the Symfony console with the ability to create a shippable phar archive—like composer does—and you have a powerful command line tool at your disposal.

Setup

Now that you have quick intro and background of the console in Laravel let’s walk through creating a custom command for Laravel. We’ll build a console command that runs a health check against your Laravel application every minute to verify uptime.

I am not suggesting you ditch your uptime services, but I am suggesting that artisan makes it super easy to build a quick-and-dirty health monitor straight out of the box that we can use as a concrete example of a custom command.

An uptime checker is just one example of what you can do with your consoles. You can build developer-specific consoles that help developers be more productive in your application and production-ready commands that perform repetitive and automated jobs.

Alright, let’s create a new Laravel project with the composer CLI. You can use the Laravel installer as well, but we’ll use composer.

composer create-project laravel/laravel:~5.4 cli-demo cd cli-demo/ # only link if you are using Laravel valet valet link composer require fabpot/goutte

Do you want to know what the beauty of that composer command was? You just used a project that relies on the Symfony console. I also required the Goutte HTTP client that we will use to verify uptime.

Registering the Command

Now that you have a new project, we will create a custom command and register it with the console. You can do so through a closure in the routes/console.php file, or by registering the command in the app/Console/Kernel.php file’s protected $commands property. Think of the former as a Closure-based route and the latter as a controller.

We will create a custom command class and register it with the Console’s Kernel class. Artisan has a built-in command to create a console class called make:command:

php artisan make:command HealthcheckCommand

This command creates a class in the app/Console/Commands/HeathcheckCommand.php file. If you open the file, you will see the $signature and the $description properties, and a handle() method that is the body of your console command.

Adjust the file to have the following name and description:

<?php namespace App\Console\Commands; use Illuminate\Console\Command; class HealthcheckCommand extends Command { /** * The name and signature of the console command. * * @var string */ protected $signature = 'healthcheck {url : The URL to check} {status=200 : The expected status code}'; /** * The console command description. * * @var string */ protected $description = 'Runs an HTTP healthcheck to verify the endpoint is available'; /** * Create a new command instance. * * @return void */ public function __construct() { parent::__construct(); } /** * Execute the console command. * * @return mixed */ public function handle() { // } }

protected $commands = [ Commands\HealthcheckCommand::class, ];

If you run php artisan help healthcheck you should see something like the following:

Setting up the HTTP Client Service

You should aim to make your console commands “light” and defer to application services to accomplish your tasks. The artisan CLI has access to the service container to inject services, which will allow us to inject an HTTP client in the constructor of our command from a service.

In the app/Providers/AppServiceProvider.php file, add the following to the register method to create an HTTP service:

// app/Providers/AppServiceProvider.php public function register() { $this->app->singleton(\Goutte\Client::class, function ($app) { $client = new \Goutte\Client(); $client->setClient(new \GuzzleHttp\Client([ 'timeout' => 20, 'allow_redirects' => false, ])); return $client; }); }

We set up the Goutte HTTP crawler and set the underlying Guzzle client with a few options. We set a timeout (that you could make configurable) and we don’t want to allow the client to follow redirects. We want to know the real status of an HTTP endpoint.

Next, update the HealthcheckCommand::__construct() method with the service you just defined. When Laravel constructs the console command, the dependency will be resolved out of the service container automatically:

use Goutte\Client; // ... /** * Create a new command instance. * * @return void */ public function __construct(Client $client) { parent::__construct(); $this->client = $client; }

The Health Check Command Body

The last method in the HealthcheckCommand class is the handle() method, which is the body of the command. We will get the {url} argument and status code to check that the URL returns the expected HTTP status c

Let’s flesh out a simple command to verify a healthcheck:

/** * Execute the console command. * * @return mixed */ public function handle() { $url = $this->getUrl(); $expected = (int) $this->option('status'); try { $crawler = $this->client->request('GET', $url); $status = $this->client->getResponse()->getStatus(); } catch (\Exception $e) { $this->error("Healthcheck failed for $url with an exception"); $this->error($e->getMessage()); return 2; } if ($status !== $expected) { $this->error("Healthcheck failed for $url with a status of '$status' (expected '$expected')"); return 1; } $this->info("Healthcheck passed for $url!"); return 0; } private function getUrl() { $url = $this->argument('url'); if (! filter_var($url, FILTER_VALIDATE_URL)) { throw new \Exception("Invalid URL '$url'"); } return $url; }

First, we validate the URL argument and throw an exception if the URL isn’t valid. Next, we make an HTTP request to the URL and compare the expected status code to the actual response.

You could get even fancier with the HTTP client and crawl the page to verify status by checking for an HTML element, but we just check for an HTTP status code in this example. Feel free to play around with it on your own and expand on the healthcheck.

If an exception happens, we return a different status code for exceptions coming from the HTTP client. Finally, we return a 1 exit code if the HTTP status isn’t valid.

Let’s test out our command. If you recall, I linked my project with valet link:

$ php artisan healthcheck http://cli-demo.dev Healthcheck passed! $ php artisan healthcheck http://ift.tt/2vB3W2f Healthcheck failed with a status of '404' (expected '200') $ echo $? 1

The healthcheck is working as expected. Note that the second command that fails returns an exit code of 1. In the next section, we’ll learn how to run our command on a schedule, and we will force a failure by shutting down valet.

Running Custom Commands on a Schedule

Now that we have a basic command, we are going to hook it up on a scheduler to monitor the status of an endpoint every minute. If you are new to Laravel, the Console Kernel allows you to run Artisan commands on a schedule with a nice fluent API. The scheduler runs every minute and checks to see if any commands need to run.

Let’s set up this command to run every minute:

protected function schedule(Schedule $schedule) { $schedule->command( sprintf('healthcheck %s', url('/')) ) ->everyMinute() ->appendOutputTo(storage_path('logs/healthcheck.log')); }

In the schedule method, we are running the command every minute and sending the output to a storage/logs/healthcheck.log file so we can visually see the results of our commands. Take note that the scheduler has both an appendOutputTo() method and a sendOutputTo() method. The latter will overwrite the output every time the command runs, and the former will continue to append new items.

Before we run this, we need to adjust the URL. By default, the url('/') function will probably return http://localhost unless you’ve updated the .env file already. Let’s do so now so we can fully test out the healthcheck against our app:

# .env file APP_URL=http://cli-demo.dev

Running the Scheduler Manually

We are going to simulate running the scheduler on a cron that runs every minute with bash. Open a new tab so you can keep it in the foreground and run the following infinite while loop:

while true; do php artisan schedule:run; sleep 60; done

If you are watching the healthcheck.log file, you will start to see output like this every sixty seconds:

tail -f storage/logs/healthcheck.log Healthcheck passed for http://cli-demo.dev! Healthcheck passed for http://cli-demo.dev! Healthcheck passed for http://cli-demo.dev!

If you are following along with Valet, let’s shut it down, so the scheduler fails. Shutting down the web servr simulates an application being unreachable:

valet stop Valet services have been stopped. # from the healthcheck.log Healthcheck failed with an exception cURL error 7: Failed to connect to cli-demo.dev port 80: Connection refused (see http://ift.tt/1mgwZgQ)

Next, let’s bring our server back and remove the route so we can simulate an invalid status code.

valet start Valet services have been started.

Next, comment out the route in routes/web.php:

// Route::get('/', function () { // return view('welcome'); // });

If you aren’t running the scheduler, start it back up, and you should see an error message when the scheduler tries to check the status code:

Healthcheck failed for http://cli-demo.dev with a status of '404' (expected '200')

Don’t forget to shut down the infinite scheduler tab with Ctrl + C!
