Composer features and specs

  • Dependency Management
    Composer allows for easy and efficient management of PHP dependencies, ensuring that the correct versions are used and conflicts are minimized.
  • Autoloading
    Composer supports autoloading, which means you don't have to manually include or require files, reducing boilerplate code.
  • Version Control
    It allows developers to specify and install the exact versions of the libraries they need, which helps in maintaining consistency across different environments.
  • Community Support
    Composer has a vast and active community, resulting in a plethora of libraries and packages readily available for use.
  • PSR Compliance
    Composer adheres to PHP-FIG PSR standards, promoting best practices and interoperability among PHP projects.
  • Custom Repositories
    Ability to use custom repositories allows for flexibility, enabling enterprises to create their own repository for internal use.

Possible disadvantages of Composer

  • Learning Curve
    Beginners may find Composer overwhelming due to its command-line interface and the complexity of managing dependencies.
  • Performance
    Installing or updating packages can sometimes be slow, particularly for projects with many dependencies.
  • Dependency Conflicts
    While Composer aims to minimize conflicts, complex projects can still face issues with dependency resolution that require manual intervention.
  • File Size
    Projects using Composer can lead to increased file sizes due to the inclusion of multiple libraries and their dependencies.
  • Security
    Including third-party packages can expose a project to potential security vulnerabilities if those packages are not well-maintained or audited.

Apache Karaf features and specs

  • Modular architecture
    Apache Karaf features a highly modular architecture that allows users to deploy, control, and monitor applications in a flexible and efficient manner. This makes it easy to manage dependencies and extend functionalities as needed.
  • OSGi support
    Karaf fully supports OSGi (Open Services Gateway initiative), which is a framework for developing and deploying modular software programs and libraries. This enables dynamic updates and replacement of modules without requiring a system restart.
  • Extensible and flexible
    Karaf's extensible architecture allows developers to integrate various technologies and custom modules, fostering a flexible environment that can suit a wide range of application types and requirements.
  • Enterprise features
    It provides a range of enterprise-ready features such as hot deployment, dynamic configuration, clustering, and high availability, which can help in building robust and scalable applications.
  • Comprehensive tooling
    Karaf comes with comprehensive tooling support including a powerful CLI, web console, and various tools for monitoring and managing the runtime environment. These tools simplify everyday management tasks.

Possible disadvantages of Apache Karaf

  • Steeper learning curve
    Due to its modular and extensible nature, Apache Karaf can have a steeper learning curve for new users, especially those unfamiliar with OSGi concepts and enterprise middleware.
  • Resource intensity
    Running and managing an Apache Karaf instance can be resource-intensive, especially when dealing with large-scale or highly modular applications. Adequate memory and processing power are required to maintain optimal performance.
  • Complex deployment
    While Karaf can handle complex deployment scenarios, setting it up and configuring it properly can be more involved compared to other simpler solutions. This complexity can increase the initial setup time and effort.
  • Limited community support
    Despite being an Apache project, the community around Apache Karaf might not be as large or active as other popular frameworks, potentially making it harder to find ample resources or immediate support.
  • Dependency management challenges
    Managing dependencies in Karaf, especially when dealing with multiple third-party libraries and their versions, can become cumbersome and lead to conflicts if not handled carefully.

  • Arguments a customer can understand not to use WordPress
    There is also no requirement to follow the PHP-FIG standards. The best thing that is build because of those standards is Composer. The most plugins I downloaded while writing use composer. The problem is that the plugins ship with their own vendor directory. While the standard is to have one vendor directory for the whole project. This results in different packages with the same or different version of it in the... - Source: dev.to / 16 days ago
  • Insights from the PHP Foundation Executive Director
    “Extensions are now very close to being like packages; they basically look like Composer packages. It’s still open to discussion whether PIE will be part of Composer someday. It’s not decided yet, but I hope it will be,” Roman added. - Source: dev.to / 21 days ago

    Composer and Packagist have become key tools for establishing the foundations of PHP-based applications. Packagist is essentially a directory containing PHP code out of which Composer, a PHP-dependency manager, retrieves packages. Their ease of use and exceptional features simplify the process of importing and managing own and third-party components into our PHP projects. - Source: dev.to / 2 months ago

  • Need advice: Java Software Architecture for SaaS startup doing CRUD and REST APIs?
    Apache Karaf with OSGi works pretty nice using annotation based dependency injection with the declarative services, removing the need to mess with those hopefully archaic XML blueprints. Too bad it's not as trendy as spring and the developers so many of the tutorials can be a bit dated and hard to find. Karaf also supports many other frameworks and programming models as well and there's even Red Hat supported... Source: about 4 years ago
