Becoming an AEM Developer: Essential Technologies and Programming Languages

To become an AEM (Adobe Experience Manager) developer, there are several core technologies and programming languages that you must be proficient in. AEM development requires both front-end and back-end skills, as well as a deep understanding of Adobe's specific ecosystem. Below, we outline the key technologies and languages you should master to become a successful AEM developer.

Java and Java-Based Technologies

Java is the primary language used in AEM development. A strong understanding of core Java concepts, especially in the context of web development with servlets and Java-based frameworks, is essential. Additionally, familiarize yourself with the JCR (Java Content Repository) standard used by AEM for content storage and management. Knowledge of servlets and filters, as well as other Java-based components, is crucial for creating custom workflows and extensions.

Apache Sling and OSGi Frameworks

AEM is built on top of Apache Sling, a framework for RESTful web applications. Understanding Apache Sling is critical for managing URL mapping, resource resolution, and request processing. Furthermore, AEM operates on the OSGi (Open Services Gateway Initiative) framework, meaning you should have a thorough understanding of OSGi for working with AEM's modular architecture, bundles, and components. Be adept at creating, configuring, and deploying OSGi bundles within AEM.

Front-End Development and Modern JavaScript Frameworks

Strong knowledge of front-end technologies is also crucial. This includes a solid grasp of HTML5 and CSS3, essential for building the front-end components of AEM websites. JavaScript is fundamental for client-side scripting, particularly with dynamic content or integrating with other client-side libraries. Familiarity with AJAX (Asynchronous JavaScript and XML) aids in building dynamic client-side content updates. Additionally, modern JavaScript frameworks such as React, Angular, and Vue.js are increasingly important for headless CMS implementations.

HTL (HTML Template Language) and AEM-Specific Tools

AEM employs HTL (formerly known as Sightly) for templating, making it a server-side templating engine to render dynamic content. Understanding HTL is essential for creating custom components and rendering content efficiently. Other AEM-specific tools and APIs, such as the AEM authoring content creation and publishing workflows, are critical. Knowledge of authoring, components, templates, and workflows is vital for configuring and deploying AEM websites.

Build Automation and Version Control

Build automation tools like Maven play a significant role in AEM projects. Maven helps manage dependencies, build projects, and handle deployments, making familiarity with it a must. Proficiency in Git or other version control systems is also crucial for managing code repositories, collaborating with others, and handling deployments.

Legacy Technologies and Content Delivery

While HTL is the primary templating engine, JSP (JavaServer Pages) is still commonly used in legacy AEM implementations. Understanding JSP can be beneficial for maintaining older AEM projects. Additionally, knowledge of content delivery networks (CDNs) and caching mechanisms, such as Dispatcher (AEM's built-in caching mechanism), is essential for improving site performance and content delivery speeds.

Optional Technologies for Advanced DevOps Practices

While not strictly necessary, familiarity with containerization technologies like Docker and DevOps tools such as CI/CD (Continuous Integration and Continuous Deployment) and Jenkins can be advantageous for modern AEM projects. These practices and tools facilitate efficient and reliable deployment processes.

Additional Adobe Tools and Features

Proficiency in other Adobe tools such as Adobe Analytics, Adobe Target, and Adobe Campaign is beneficial if you are working in an integrated marketing environment. Keeping up with the evolving features of AEM and related Adobe tools ensures that your skills remain relevant and up-to-date.
