Angular et ASP.NET Core : une équipe gagnante

Découvrez comment Angular et ASP.NET Core peuvent s’associer pour créer une équipe gagnante et développer des applications web modernes et performantes !

Le fonctionnement sans heurts d’une application nécessite une construction robuste et une coordination sans faille entre ses technologies front-end et back-end. Le front-end est responsable de la définition de l’interface utilisateur et de l’expérience utilisateur d’une application, tandis que le back-end alimente ses fonctionnalités et gère la logique.

C’est pourquoi il est impératif que les développeurs trouvent une combinaison de technologies qui garantisse une faisabilité maximale entre les deux extrémités, ce qui permettra de créer une application robuste et fonctionnelle.

Coding is the foundation of any application. It is the process of writing instructions in a programming language that a computer can understand and execute. It requires a deep understanding of the underlying technologies and their associated frameworks.

Since its conception in the late 1980s, HyperText Markup Language (HTML) has persisted as a critical element in displaying web pages online.  This ubiquitous programming language continues to offer a detailed framework for structuring the content we see and interact with on the web, allowing us to format text and multimedia components in plain-text code, which is simple enough to change when the need arises.

The Transformation of HTML

As is the case with nearly all programming languages, HTML has transformed to incorporate dozens of new features over the decades since its introduction, accommodating typical contemporary pressures such as community feedback/critique and the rapid growth of adjacent web development technologies. The results of this transformation are easily visible to us in the output of modern HTML code; for example, the most recent HTML iteration–HTML5, introduced in 2014–offers new, simple elements for embedding video and audio files, as well as much-needed improvements in mobile display and overall mobile functionality.

Flutter is a new framework for developing mobile apps that promise to be faster and more efficient than React Native. But what exactly is Flutter, and how does it compare to React Native?

Flutter is a mobile app SDK that allows developers to create high-quality native apps for both iOS and Android. Flutter uses the Dart programming language, which is similar to JavaScript, but with some important differences.

This might sound like a joke, but it’s actually not. First, let’s define inheritance. Inheritance is the ability to use polymorphism to override a method with another implementation. You inherit from a class, and you override one of its virtual functions. This results in that code having an object that will no longer invoke the old base class method, but rather the new overridden method. Kind of easy, right?

Polymorphism Is the Ability To Have Old Code Invoke New Code

Well, there’s nothing intrinsically special about class-based OOP that prevents you from implementing the above in a functional context. In a functional programming language, you can have a reference to a function, and replace the function it’s pointing to, before passing in your function reference to some method in need of a function with the specified signature. This achieves the exact same result as « classic polymorphism. »

Apple has released an OS update. Packaged in with it is the latest version of Safari, 16.

Expected to be released ahead of next month’s macOS 13, Safari 16 is packed with updates, making it one of the most capable browsers available.

For web designers, the significance is the forward momentum in web technologies that enable freer design work and fewer hacks to achieve complex layouts. Little by little, CSS recommendations are being implemented to the point that using JavaScript for layout is rapidly becoming as unnecessary as it is disliked.

Some of this was announced in June in the Safari 16 beta. But a lot has been added in the last couple of months. So here’s what’s new in Safari 16 today.

CSS Container Queries

The most exciting addition to Safari 16 is CSS Container Queries.

It is hard to understate how in-demand this feature has been; if you imagine an edit button on Twitter that gifted you crypto every time you corrected a typo, you’d be getting close to how popular this feature is.

Until now, media queries have detected the whole viewport. And so, if you have an element like a card, for example, that needs to change at smaller viewports, you need to calculate the available space and adapt the element’s design accordingly. Unfortunately, this frequently gets out of sync with edge cases causing more than a few headaches for front-end developers.

Media queries are severely restrictive to modern layout methods like Grid that wrap elements automatically because there is no way to detect how the elements are laid out.

Container Queries solve this by allowing you to define styles based on the size of the actual containing element; if a div is 300px wide, the contents can have one design, and if it’s 400px wide, they can have a different design—all without caring what size the whole viewport is.

This is dangerously close to OOP (Object Orientated Programming) principles and almost elevates CSS to an actual programming language. (All we need is conditional logic, and we’re there.)

The latest versions of Chrome, Edge, and now Safari (including mobile) support CSS Grid. Even discounting the rapid decline of Twitter, this is way more exciting than any edit button.

CSS Subgrid

Speaking of Grid, if you’ve built a site with it (and if you haven’t, where have you been?), you’ll know that matching elements in complex HTML structures often results in nesting grids. Matching those grids requires careful management, CSS variables, or both. With CSS Subgrid, grids can inherit grid definitions from a grid defined higher up the hierarchy.

CSS Subgrid has been supported by Firefox for a while but is not yet part of Chrome or Edge. Until there’s wider support, it’s not a practical solution, and using a fallback negates any benefit of using Subgrid. However, its introduction in Safari will surely herald rapid adoption by Google and Microsoft and moves the web forward considerably.

CSS Subgrid is likely to be a practical solution within 18 months.

AVIF Support

AVIF is an exceptionally compact image format that beats even WebP in many instances. It even allows for sequences, creating what is essentially an animated GIF but smaller, and for bitmaps.

AVIF is already supported by Chrome, with partial support in Firefox. Safari now joins them.

AVIF support is one of the more valuable additions to Safari 16 because you’re probably already serving different images inside a picture element. If so, your Safari 16 users will begin receiving a smaller payload automatically, speeding up your site and boosting UX and SEO.

Enhanced Animation

Safari 16 introduces some significant improvements in animation, but the one that catches the eye is that you can now animate CSS Grid.

Yes, let that sink in. Combine Container Queries and animation. The possibilities for hover states on elements are tantalizing.

Safari 16 also supports CSS Offset Path — known initially as CSS Motion Path — which allows you to animate elements along any defined path. This enables the kind of animated effect that previously needed JavaScript (or Flash!) to accomplish.

Chrome, Edge, and Firefox all support CSS Offset Path; the addition of Safari means it’s now a practical solution that can be deployed in the wild.

Web Inspector Extensions

Announced as part of the beta release, Web Inspector Extensions allow web developers to create extensions for Safari, just as they would for Chrome.

Web Inspector Extensions — or Safari Extensions as they’re destined to be known — can be built in HTML, CSS, and JS, so the learning curve is shallow. It’s a good route into app development for web designers.

Because the underlying technology is the same as other browser extensions, anyone who has made a Chrome, Edge, or Firefox extension will be able to port it to Safari 16+ relatively easily. As a result, there should be a rapid expansion of the available extensions.

Improved Accessibility

Accessibility is key to an effective and inclusive web. Be like Bosch: everybody counts, or nobody counts.

When testing a design for accessibility, emulators don’t cut it. In my experience, Safari has some of the most reliable accessibility settings, especially when it comes to Media Queries like prefers-reduced-movement.

Further gains in this field mean that Safari continues to be an essential tool for QA tests.

Reduced Resets

Finally, I want to throw up my hands to celebrate the reduced number of non-standard CSS appearance settings.

For years we’ve been prefacing our style sheets with elaborate resets like Normalize, designed to undo all the assumptions browser developers make about design and the UI preferences of their engineers.

Safari 16 has reportedly “Removed most non-standard CSS appearance values.” How effective this is and how much we can rely on it given the other browsers on the market remains to be seen. However, like many of Safari 16’s changes, it’s a step towards a browser that’s on the developers’ side instead of an obstacle to overcome.

Last year we saw the launch of a new Web programming language Dart – Structured Web Programming from Google. A very interesting approach to support web application development. Not so long after Go, Groovy, Ruby, Scala, << Name your DSL here >>; we see Dart. Is it a good thing to have at least one programming language to solve one problem? The answer is, like we already know, it depends.

Stay Away From “Do it Yourself”

It is your choice as to if you will try to do things yourself or allow the truly seasoned professionals to help out. Some decide that they are going to try to go it alone when they are programming something new, but this often ends up in a less than desirable place. It may even be more expensive than just hiring an expert who can help you get it programmed for you in the first place.

Alert windows are widely used across websites where an alert message acts as a mode to ‘interrupt’ the current flow of the user journey. A simple example of a JavaScript alert would be someone filling in details on the sign-up page and submitting the details without entering some mandatory information. This user flow also needs to be verified when Selenium automation testing is performed on the web product. 

Handling pop-ups and alerts are one of the common test scenarios that should be tested using Selenium WebDriver. In this post of the Selenium Python tutorial series, we look at how to handle JavaScript alerts in Python. It is worth mentioning that the core fundamentals of JavaScript alerts and popups remain unchanged irrespective of the programming language used for Selenium.
