Dieses Modul erklärt einige der wichtigsten Vorteile des Frameworks, wie Sie Ihre Entwicklungsumgebung einrichten und wie Sie gängige Webentwicklungs- und Bereitstellungsaufgaben ausführen.</p></div><section aria-labelledby="voraussetzungen"><h2 id="voraussetzungen"><a href="#voraussetzungen">Voraussetzungen</a></h2><div class="section-content"><p>Bevor Sie mit diesem Modul beginnen, sollten Sie verstehen, was serverseitige Webprogrammierung und Web-Frameworks sind, idealerweise durch das Lesen der Themen in unserem Modul <a href="/de/docs/Learn_web_development/Extensions/Server-side/First_steps">Erste Schritte der serverseitigen Website-Programmierung</a>. Allgemeine Kenntnisse über Programmierkonzepte und <a href="/de/docs/Web/JavaScript">JavaScript</a> werden wärmstens empfohlen, sind jedoch nicht zwingend notwendig, um die Kernkonzepte zu verstehen.</p> <div class="notecard note"> <p><strong>Hinweis:</strong> Diese Website hat viele nützliche Ressourcen, um JavaScript <em>im Kontext der clientseitigen Entwicklung</em> zu lernen: <a href="/de/docs/Web/JavaScript">JavaScript</a>, <a href="/de/docs/Web/JavaScript/Guide">JavaScript Leitfaden</a>, <a href="/de/docs/Learn_web_development/Getting_started/Your_first_website/Adding_interactivity">JavaScript-Grundlagen</a>, <a href="/de/docs/Learn_web_development/Core/Scripting">JavaScript</a> (Lernen). Die Kernsprache JavaScript und die Konzepte sind für die serverseitige Entwicklung auf Node.js dieselben, und dieses Material wird relevant sein. Node.js bietet <a href="https://nodejs.org/dist/latest-v10.x/docs/api/" class="external" target="_blank">zusätzliche APIs</a>, um Funktionalitäten zu unterstützen, die in umgebungslosen Umgebungen nützlich sind (z. B. zur Erstellung von HTTP-Servern und zum Zugriff auf das Dateisystem), unterstützt jedoch keine JavaScript-APIs für Arbeiten mit dem Browser und dem DOM.</p> <p>Diese Artikelserie bietet einige Informationen über das Arbeiten mit Node.js und Express, und es gibt viele andere hervorragende Ressourcen im Internet und in Büchern — einige davon verlinkt von <a href="https://stackoverflow.com/questions/2353818/how-do-i-get-started-with-node-js/5511507" class="external" target="_blank">Wie fange ich mit Node.js an?</a> (Stack Overflow) und <a href="https://www.quora.com/What-is-the-greatest-resource-for-learning-Node-js-for-a-newbie" class="external" target="_blank">Was sind die besten Ressourcen für das Lernen von Node.js?</a> (Quora).</p> </div></div></section><section aria-labelledby="tutorials"><h2 id="tutorials"><a href="#tutorials">Tutorials</a></h2><div class="section-content"><dl> <dt id="einführung_in_expressnode"><a href="/de/docs/Learn_web_development/Extensions/Server-side/Express_Nodejs/Introduction">Einführung in Express/Node</a></dt> <dd> <p>In diesem ersten Express-Artikel beantworten wir die Fragen "Was ist Node?" und "Was ist Express?" und geben Ihnen einen Überblick darüber, was das Express-Web-Framework besonders macht.
