Que vous soyez un développeur amateur, expérimenté ou expert, nos tutoriels vous prépareront à développer des applications pour Nextcloud.

Nous nous concentrons sur le développement d’applications open source et nous nous engageons à fournir à notre communauté tous les outils dont elle a besoin pour transformer ses idées en véritables applications Nextcloud.

Pourquoi les applications Nextcloud ?

Alors, qu’attendez-vous ?

Lisez la suite pour découvrir nos tout nouveaux tutoriels de développement d’applications Nextcloud !

Développer une application complète

Si vous avez une idée révolutionnaire pour une application, c’est l’occasion de la développer de A à Z !

Dans ce tutoriel, vous apprendrez à développer une application complète avec une barre de navigation et une base de données.

Après le tutoriel, vous saurez comment :

• Créer une application autonome avec un menu de navigation
• Utiliser la base de données
• Étendre l’API de Nextcloud avec les points de terminaison de votre application
• Exporter dans un fichier les données stockées par votre application dans la base de données

Ajouter des tests automatisés à votre application

Après avoir créé votre propre application, vous pouvez apprendre à configurer des tests automatisés pour celle-ci !

Apprenez à utiliser GitHub Actions – une plateforme d’intégration et de livraison continues (CI/CD) qui vous permet d’automatiser votre flux de développement. Avec GitHub Actions, les développeurs d’applications n’ont pas besoin de déployer un environnement de test pour toutes les différentes versions de Nextcloud, de PHP et de système de base de données.

Vous verrez à quel point il est pratique d’avoir des tests qui sont déclenchés automatiquement afin qu’ils s’exécutent pour chaque demande d’extraction.

Après le tutoriel, vous saurez comment :

• Utiliser les actions GitHub pour mettre en place un environnement de test Nextcloud spécifique
• Configurer les tests à exécuter
• Mettre en œuvre les tests
• Voir si les tests se sont déroulés avec succès

Techniques de base de dépannage

Votre application ne fonctionne pas comme prévu ? Vous ne savez pas pourquoi le code ne fonctionne pas correctement ?

Ce tutoriel vous apprendra à :

• Redémarrer votre instance Nextcloud
• Accéder à la console du navigateur
• Obtenir le fichier Nextcloud.log

EXTRA : Mise en place d’un environnement de test – Reproduire les bugs et tester les PR

Pour ceux qui travaillent sur le cœur de Nextcloud, vous pouvez apprendre à mettre en place un environnement de test facile en utilisant l’Instance de test facile Nextcloud de Simon.

Il s’agit d’une instance super rapide utilisant docker pour Nextcloud afin de lancer rapidement différentes versions de Nextcloud, ce qui est idéal pour reproduire les bugs, tester les PR, et tester les changements UX.

Après ce tutoriel, vous saurez comment :

• Mettre en place un environnement Nextcloud local à des fins de test
• Test des PR pour Nextcloud
• Reproduire rapidement des bugs sur différentes versions de Nextcloud et obtenir des logs
• Mettre en place plusieurs environnements pour tester les changements UX auprès des utilisateurs

Nextcloud Text is perfect for note-taking, outlines and templates and it is also used in some other apps like Collectives for the text editing component. When you want to work in a simple and uncluttered environment, Text is your ideal choice. It offers a variety of rich formatting options without the more advanced functionalities of a complete office app like Writer in Nextcloud Office. The Text App saves its files as ‘markdown’ files which is very popular among writers, bloggers and techies alike.

Calling all developers!

Like any app, Text gets regular updates, bug fixing and development, and it is a great place to get started contributing to Nextcloud! Several Nextcloud developers, like Max and Jonas who developed the Collectives app, got their first contributions to Nextcloud in through Text. And if you get involved, you’ll certainly encounter them, triaging issues and fixing bugs!

Do you:

• Already have experience programming?
• Are familiar with tools y.js, vue.js and tiptap?
• Curious to learn about new technologies?

Then you should contribute to the Text App!

The tools being used (y.js, vue.js, tiptap) are all built by people who know their craft, have looked into the problems in depth, and found innovative solutions which makes Text a great place to learn how to build up code for those with some experience in programming.

About y.js

y.js was implemented to solve the problem of merging conflicts while collaborative editing. Dealing with these conflicts is a very interesting challenge that people have studied for decades. The requirement for combining the changes of different people was to have a certain order: the changes of person A would be merged first, then the changes of person B, etc., even if the changes of person A and B were made at the same time. The order has to be respected. This means the submission of the changes was often out of order, changes had to be resubmitted, and the user experience was not smooth. y.js was invented between 2016 and 2020 as part of a research project, and it became the first widely used implementation of a CRDT (conflict-free replicated data types) algorithm for shared editing. CRDTs allow collaborating without worrying about the resolution of conflicts. This means we can allow accepting the changes even if they arrive in different orders. The implementation of y.js in Text resulted in great improvements for the performance and user experience.

Getting started

In the Text repository, there’s a very accessible entry-point for new contributors: all issues are triaged, feedback on pull requests is provided fast, and the team is continuously investing in reducing technical debt.

To get started, a variety of ‘good first issues’ are ready for you! Some of the issues just require a one line change in the code and are a very accessible starting point to get some confidence, while other issues are detailed and provide a great chance to learn how the code is structured. Overall, all issues contain elaborate explanations and help is available if you get stuck!

With that, let’s get going!

The Developer Tutorial Series is a program where we help developers improve their coding skills by providing them the tools and step-by-step guides on a variety of topics to succeed.

Nextcloud Dashboard

The Dashboard is where you start your day. You have your cup of coffee or tea in hand, and are ready to start your work.

Who messaged you? Do you have an important email to answer? With Nextcloud Dashboard, you have a quick overview of everything happening in your Nextcloud and can get a productive head start to your day. It makes it easy to pick up where you left off on a project through the Deck widget, for example, or an upcoming Task.

There’s a whole variety of widgets to choose from, and with some practice you can even make your own!

Start Customizing your own Widget!

Have an idea for a new widget on your dashboard? After completing our fourth tutorial, you will know how to create widgets in Vue.js, an open source, front-end JavaScript model.

Vue.js is mainly utilized for building user interfaces and single-page applications and is known to be a progressive and approachable framework. Learn more about Vue.js here.

In the written tutorial, we first teach you how to create a simple dashboard widget using pure (or vanilla) Javascript and then you will learn how to do it successfully on Vue.js.

We hope you learn from and have fun with this tutorial!

If you have any questions or want to share your new widget, post in the forums!
