by Alex Johnson 61 views

This article serves as a comprehensive deprecation tracker for the NumaHOP project. We'll delve into the deprecated components within NumaHOP, focusing on AngularJS, SpringBoot, and Mirador2. This discussion aims to provide clarity on the status of these technologies and outline the necessary steps for updating or migrating away from them. Understanding deprecation is crucial for maintaining the health and longevity of any software project, and NumaHOP is no exception.

Understanding Deprecation in NumaHOP

Within the NumaHOP ecosystem, deprecation signifies that certain features, libraries, or frameworks are no longer actively supported or recommended for use. This could be due to various reasons, such as the emergence of newer, more efficient technologies, security vulnerabilities, or simply a shift in the project's architectural direction. When a component is marked as deprecated, it typically means that future updates, bug fixes, or security patches are unlikely to be provided. Continuing to use deprecated components can introduce technical debt, increase the risk of security breaches, and hinder the adoption of new features and improvements.

Why Track Deprecations?

  • Security: Deprecated components often lack the latest security patches, making them vulnerable to exploits. Tracking deprecations allows us to proactively address these vulnerabilities and ensure the security of NumaHOP.
  • Performance: Newer technologies often offer performance improvements over their predecessors. By migrating away from deprecated components, we can enhance the overall performance and efficiency of NumaHOP.
  • Maintainability: Working with deprecated technologies can become increasingly challenging as the ecosystem evolves. Finding developers with the necessary expertise and obtaining support can be difficult. Addressing deprecations ensures the long-term maintainability of NumaHOP.
  • Innovation: Deprecation allows us to embrace new technologies and architectural patterns, fostering innovation and keeping NumaHOP at the forefront of its field.

Our Approach to Deprecation

Our approach to handling deprecations within NumaHOP is proactive and transparent. We aim to:

  1. Clearly Identify Deprecated Components: This tracker serves as a central repository for identifying deprecated components within NumaHOP.
  2. Provide Ample Notice: We will provide sufficient notice before completely removing deprecated components, allowing developers time to migrate to newer alternatives.
  3. Offer Migration Guidance: We will offer guidance and resources to help developers migrate away from deprecated components. This may include documentation, code examples, and community support.
  4. Encourage Community Involvement: We encourage the NumaHOP community to actively participate in the deprecation process by identifying deprecated components, suggesting alternatives, and contributing to migration efforts.

Deprecated Components in NumaHOP

Let's take a closer look at the specific components within NumaHOP that are currently marked as deprecated:

1. AngularJS (#7)

AngularJS is a JavaScript-based front-end web framework that was widely used for building dynamic web applications. However, it has been superseded by its successor, Angular (without the "JS"), which offers significant improvements in terms of performance, architecture, and features. AngularJS reached its end-of-life (EOL) on December 31, 2021, meaning that Google no longer provides official support, security updates, or bug fixes for it.

  • Impact on NumaHOP: The use of AngularJS in NumaHOP presents several challenges. The lack of security updates makes applications vulnerable to potential threats. Performance limitations can hinder the user experience. Furthermore, the diminishing pool of AngularJS developers and resources makes maintenance and future development more difficult.
  • Migration Strategy: Migrating from AngularJS to Angular is a significant undertaking but is crucial for the long-term health of NumaHOP. This typically involves rewriting components and modules using the Angular framework, updating the application's architecture, and adopting new development patterns. A phased migration approach, where AngularJS components are gradually replaced with Angular equivalents, can help minimize disruption and risk.
  • Considerations for Migration: When migrating from AngularJS, it's essential to carefully plan the migration strategy, assess the complexity of the application, and choose the appropriate Angular version. Utilizing tools and resources like the Angular Upgrade Guide can streamline the process. Thorough testing is crucial to ensure that the migrated application functions correctly and maintains its integrity.

2. SpringBoot (#42)

SpringBoot is a popular Java-based framework for building web applications and microservices. While SpringBoot itself is not deprecated, specific versions or dependencies within the NumaHOP project may be marked as deprecated due to compatibility issues, security vulnerabilities, or the availability of newer versions with enhanced features. It's crucial to identify which specific aspects of SpringBoot are deprecated within the NumaHOP context.

  • Impact on NumaHOP: Deprecated SpringBoot dependencies can lead to security risks, compatibility issues with other libraries, and a lack of access to the latest features and performance improvements. Using outdated versions can also make it more difficult to find support and resources when troubleshooting problems.
  • Migration Strategy: The migration strategy for SpringBoot typically involves upgrading to the latest supported version of the framework and its dependencies. This may require code modifications to align with API changes and new best practices. Reviewing the SpringBoot release notes and migration guides is essential for a smooth transition.
  • Considerations for Migration: Before upgrading SpringBoot, it's vital to assess the impact on the existing codebase, identify any breaking changes, and conduct thorough testing to ensure compatibility. Utilizing dependency management tools like Maven or Gradle can simplify the upgrade process and minimize potential conflicts.

3. Mirador2

Mirador2 is an open-source, web-based image viewer specifically designed for accessing and displaying images from repositories that adhere to the International Image Interoperability Framework (IIIF) standards. While Mirador2 has been a valuable tool for image viewing and comparison, newer versions or alternative IIIF viewers may offer improved features, performance, or security enhancements. Deprecation in this context suggests a move towards a more modern IIIF viewing solution.

  • Impact on NumaHOP: Continuing to use Mirador2 without considering alternatives may limit access to new IIIF features, hinder performance improvements, and potentially introduce security vulnerabilities. Exploring newer viewers can provide a better user experience and align NumaHOP with the latest IIIF standards.
  • Migration Strategy: Migrating from Mirador2 involves evaluating alternative IIIF viewers, such as Mirador3 or other compatible solutions. This includes assessing their features, performance, compatibility with NumaHOP's requirements, and ease of integration. A phased rollout, where the new viewer is initially offered as an option alongside Mirador2, can allow users to gradually transition to the new platform.
  • Considerations for Migration: When choosing an alternative IIIF viewer, consider factors such as its support for different IIIF specifications, its performance with large images, its user interface and customization options, and its community support. Thorough testing and user feedback are essential to ensure a successful migration.

Identifying and Reporting Deprecated Components

This tracker serves as a living document, and we encourage the NumaHOP community to actively contribute to its accuracy and completeness. If you encounter a part of NumaHOP that you believe is deprecated and requires updating, please follow these steps:

  1. Create a New Issue: Open a new issue in the NumaHOP project's issue tracker.
  2. Clearly Describe the Deprecated Component: Provide a clear and concise description of the component, including its name, version (if applicable), and the reason why you believe it is deprecated.
