Retour vers le futur: Pages Web côté serveur avec Kotlin (Pt. 1)

,

Dans cette série, nous allons apprendre à créer des pages web côté serveur avec Kotlin. Vous découvrirez comment créer des applications web modernes et performantes. Prêt à voyager dans le futur ? Allons-y !

Le développement Web a subi de nombreux changements depuis que l’Internet est devenu populaire dans les années 1990 :

L’architecture du développement web a connu une variété de changements depuis que l’internet est devenu populaire dans les années 1990 :

Tout d’abord, il y a eu les pages HTML les plus basiques, complètement statiques, sans aucune dynamique. Plus tard, des technologies telles que l’interface commune de passerelle (Common Gateway Interface) ont permis de générer le code HTML d’une page de manière programmatique. Puis sont arrivés des moteurs de modèles tels que JavaServer Pages (maintenant Jakarta Server Pages), ASP.NET et Thymeleaf, qui ont permis aux développeurs de travailler avec des fichiers de modèles principalement « ressemblant à HTML » avec du code de programmation intermélangé.

Ensuite, des frameworks de « script côté client » basés sur Javascript tels qu’Angular, React et Vue sont apparus, ce qui a transformé le développement web en deux disciplines distinctes : le développement « backend » qui contenait le code traditionnel du serveur web et de la logique métier, ainsi que le développement « front-end » (en utilisant les frameworks ci-dessus) qui se concentrait sur la visualisation d’un site web et recevait des données du backend.

Cependant, cela ne signifie pas que les tendances de développement ne progressent que dans une seule direction et jamais en arrière. Par exemple, les bases de données NoSQL telles que MongoDB ont rapidement gagné en popularité en grande partie en raison de leur capacité à contenir des données non structurées par rapport aux bases de données SQL traditionnelles telles que PostgreSQL et MySQL, mais ces dernières ont également évolué et peuvent maintenant contenir des données non structurées via les types de données JSONB et JSON, respectivement. De même, de nouveaux frameworks Javascript tels que Next.js commencent à offrir des options pour le rendu côté serveur en plus de leurs capacités de rendu côté client traditionnelles. De nouveau, les moteurs de modèles côté serveur comme Thymeleaf ont également continué à évoluer, Thymeleaf lançant une nouvelle version du framework le mois dernier.

AWS Fargate: Deploying Jakarta EE Applications on Serverless Infrastructures

,

Jakarta EE is a unanimously adopted and probably the most popular Java enterprise-grade software development framework. With the industry-wide adoption of microservices-based architectures, its popularity is skyrocketing and during these last years, it has become the preferred framework for professional software enterprise applications and services development in Java.

Jakarta EE applications used to traditionally be deployed in run-times or application servers like Wildfly, GlassFish, Payara, JBoss EAP, WebLogic, WebSphere, and others, which might have been criticized for their apparent heaviness and expansive costs. With the advent and the ubiquitousness of the cloud, these constraints are going to become less restrictive, especially thanks to the serverless technology, which provides increased flexibility, for standard low costs.

Learn to Access Java Database With Jakarta Data

,

Dealing with a database is one of the biggest challenges within a software architecture. In addition to choosing one of several options on the market, it is necessary to consider the persistence integrations. The purpose of this article is to show some of these patterns and learn about a new specification proposal, Jakarta Data, which aims to make life easier for developers with Java.

Understanding the Layers That Can Make Up Software

Whenever we talk about complexity in a corporate system, we focus on the ancient Roman military strategy: divide and conquer or divide et impera. To simplify the whole, we break it down into small units.

EclipseCon 2021 Conference Report

,

EclipseCon 2021 took place October 25-28. EclipseCon has long been a world-class conference for all things Eclipse. With the Java EE transition to the Eclipse Foundation, EclipseCon has become a truly significant event for Jakarta EE and MicroProfile developers. Due to the pandemic, the 2021 event was virtual (and free!). Jakarta EE unsurprisingly had a strong presence at the conference with talks on Jakarta EE 9.x, Jakarta EE 10, MicroProfile 4.x, MicroProfile 5, Jakarta Security, Jakarta Concurrency, Jakarta REST, Jakarta NoSQL, and MicroProfile GraphQL from speakers such as Tanja Obradovic, Ivar Grimstad, Josh Juneau, Otavio Santana, Emily Jiang, Steve Millidge, Arjan Tijms, Werner Keil, Ed Burns, Rudy De Busscher, and Graham Charters. 

I delivered two talks and participated in a panel at the conference focused on Java, Jakarta EE, and Azure. I also helped organize Community Day along with Werner Keil and Petr Aubrecht.

Get Ready for Jakarta EE 10!

,

Jakarta EE 10 is on its way! This is the third release of Jakarta EE since the transition from the Java Community Process (JCP) to Eclipse Foundation. In this session, we will go through every aspect of Jakarta EE 10 and how this release lowers the barriers of entry, eases the migration, and lays the foundation for a platform for future innovation. We will also look ahead towards what future releases may bring. There will be a demo including converting from the javax.* to jakarta.* namespace as well as looking at available implementations.

Why You Should Join EclipseCon Community Day

,

EclipseCon Community Day is on Monday, October 19 14:00 to 18:00 CET (the day before the start of the main EclipseCon conference). Community Day at EclipseCon has always been a great event for Eclipse working groups and project teams. This year both EclipseCon and Community Day is virtual and free. Space for Community Day is limited, so please register and save your spot soon.

We have a packed agenda centered on the Jakarta EE, MicroProfile and Cloud Native Java communities. If there is a set of very focused sessions you should attend on these topics, the agenda offers the one place this year to do so. The sessions are intended not only for learning, but also for the community to actively engage with some key leaders. Note, after you register for EclipseCon, you will need to reserve your spot for Community Day through the Swapcard platform (let me know if you run into any issues).

Jakarta EE 8

Two years after Oracle handed over Enterprise Java to the Eclipse Foundation, they provided Jakarta EE, and since then, they have released version 8. As its name suggests, this version is compatible with Java EE 8, but is now completely open-source, and therefore, royalty-free.
