For those who haven’t actively used Service Providers in Laravel, it’s a mystical “term”: what “service” do they actually “provide”, and how exactly does it all work? I will explain it in this article. Default Laravel Service Providers Let’s start with the default service providers included in Laravel, they are all in the app/Providers folder: They are all PHP classes, each related to its topic: general “app”, Auth, Broadcasting, Events, and Routes. But they all have one thing in common: the boot() method. Inside of that method, you can write any code related to one of those sections: auth, events, routes, etc. In other words, Service Providers are just classes to register some global functionality. They are separated as “providers” because they are executed really early in the Application Lifecycle, so it is convenient something global here before the execution script comes to Models or Controllers. The most amount of functionality is in the RouteServiceProvider, let’s take a look at its code: 1class RouteServiceProvider extends ServiceProvider 3 public const HOME = ‘/dashboard’; 9 $this->routes(function () { 12 ->group(base_path(‘routes/api.php’)); 14 Route::middleware(‘web’) 15 ->group(base_path(‘routes/web.php’)); 21 RateLimiter::for(‘api’, function (Request $request) { 22 return Limit::perMinute(60)->by($request->user()?->id ?: $request->ip()); This is the class where route files are configured, with routes/web.php and routes/api.php included by default. Notice that for the API there are also different configurations: endpoint prefix /api and middleware api for all the routes. You can edit those Service Providers however you want, they are not in the /vendor folder. Typical customization of this file happens when you have a lot of routes and you want to separate them in your custom file. You...

How to make a CLI based movie scrapper using NodeJS This guide will instruct you on how to make a CLI application that will ask the user for movie, and present info about that movie in return. To be most successful you should have at least a beginers understanding of Node and NPM. You should also have a basic understanding of using bash to navigate files. Although you are free to use a GUI application if you wish, only terminal examples will be provided. Prerequsites A text editor or IDE of your choice. A terminal that is capable of running bash commands. Part One (Setup Folder & File Structure, Install NPM Packages) First, create the root folder for the project. This guide will call it movie-scrapper. Then navigate into the newly created folder. mkdir movie-scrapper && cd movie-scrapper Within the movie-scrapper directory run the following command. This will create the package.json file. You need to make two modifications to this file. Add "type": "module" to the top level, and "start": "node src/index.js" to the scripts section. It should look like this. (You may have some slight differences depending on your pesoral npm settings, just focus on the changes needed above) {"name":"movie-scrapper","version":"1.0.0","description":"","main":"index.js","type":"module","scripts":{"start":"node src/index.js","test":"echo \"Error: no test specified\" && exit 1"},"keywords":[],"author":"","license":"ISC","dependencies":{}} Run this next command in your terminal to install the npm packages axios dotenv and inquirer npm i axios dotenv inquirer You should now see a node-modules directory in your root folder. . ├── node_modules ├── package-lock.json ├── package.json You should also see the newly installed packages listed in your package.json dependcies Now you are going to create a .env...
Hi, I’m Valerio, software engineer, founder & CTO at Inspector. I decided to write this post after responding to a support request from a developer who asked me how he can monitor his Laravel application by services and not by hostnames. The company is working on a backend API for a mobile app. The APIs are running on a set of AWS EC2 instances managed by an Autoscaling Group. After a thorough investigation into the reason for this request, here is the solution we found. What is an autoscaling group? An Autoscaling Group contains a collection of VM instances that are treated as a logical grouping for the purposes of automatic scaling and management of specific component of your system. In Laravel is quite easy to separate your application in logical components that runs in different servers, like APIs, background Jobs workers, web app, scheduled tasks (cron), etc, so they can scale in and out indipendently based on their specific workload. Every established cloud provider allwos you to configure Autoscaling Groups, or you can use other technologies like Kubernetes. The result is the same: Due to the constant turnover of servers to handle the application load dynamically you could see a bit of mess in your monitoring charts. A lot of trendlines turn on and off continuously, one for each underlying server. Grouping monitoring data by service name It may be more clear to use a human friendly service name to represent all your servers inside the same Autoscaling Group. Since transactions in Inspector are grouped by the hostname, we can use the Inspector library to “artificially” change it...
It’s no secret that Ionic and React Native compete in the cross-platform application development ecosystem. A quick online search will bring up countless articles comparing the two cross-platform solutions. In these articles, advocates for React Native will often lean on performance as the biggest reason to choose one platform over another. Their assumption is that, because React Native orchestrates native UI controls (as opposed to rendering the UI in a browser, like Ionic) then it must be faster. The problem? None of these explanations ever seem to be centered around actual performance metrics. Rather, what the authors seem to fall back on is the perception that React Native is “more native”, and thus it has better performance. Well, does React Native have better performance? We decided to create competing applications, with the same feature-set, and run some of our own tests on the same exact iPhone 11 Pro Max. Let’s take a look at how it played out. Ionic vs. React Native First, if you’re just getting to know Ionic or React Native, let’s briefly summarize how the two are different in terms of their approach and underlying architecture. Ionic fully subscribes to the philosophy of leveraging web technologies to deliver its applications. React Native, on the other hand, also runs using JavaScript (JS), but does so under the guise of orchestrating platform-specific user interface (UI) controls. Both platforms create real native apps with full native access through plugins and custom native code. To learn more about the differences between Ionic and React Native, check out our comparison guide. Boot Time The time that the application takes to load...
Today, millions of mobile applications are available on major online play stores for multiple platforms. The majority of the world’s population now has access to smartphones and mobile apps, but they least care about which technology is used in developing these apps. They are more concerned about how the app can add value to their lives. They care about is the app’s performance and responsiveness during use. Users also often get intrigued by the feature set of a mobile app. When it comes to analyzing the performance and responsiveness of the application, the technologies used to build these apps play a critical role. For mobile apps, these technologies can be categorized into native and cross-platform development technologies. Native mobile app development technologies are more mature and have certain advantages and benefits and a few downsides as well. Today, we will explore them and find out how your business can leverage these to take the lead. But prior to knowing what the pros and cons of native development are, let’s learn more about what native development is and how it functions. What Is Native App Development? Native app development refers to developing mobile applications exclusively for one platform. The native apps are built employing the techniques and programming languages specific to the platform. For example, if you want to build an iOS app, you can use Swift and Objective C, and for an Android app, you have Kotlin and Java. Native mobile apps are preferred for various reasons. Mostly for superior user experience and exceptional app performance. Native technologies provide more control over the UI/UX of the app, hence making...
