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.

Retrofit features and specs

  • Easy to Use
    Retrofit provides a simple and intuitive API for making HTTP requests, making it easy to integrate with your Android applications.
  • Type-Safe HTTP Calls
    With Retrofit, HTTP requests are made using method calls, and responses are automatically converted to Java objects. This type safety helps reduce errors in making network calls.
  • Flexible and Extensible
    Retrofit supports a variety of converters (like Gson, Jackson, Moshi, Protobuf), adapters (like RxJava, Kotlin Coroutines), and other customizations, making it highly adaptable to various needs.
  • Annotation-Based Configuration
    Annotations like @GET, @POST, and @Query make defining APIs more declarative and concise, reducing boilerplate code.
  • Built-In Support for Pagination
    Retrofit's integration with libraries like Paging makes it straightforward to implement paginated data loading.
  • Integration with OkHttp
    Retrofit seamlessly integrates with OkHttp, which provides caching, connection pooling, and HTTP/2 support, thus enhancing performance and reliability.

Possible disadvantages of Retrofit

  • Learning Curve
    While easy to use, it has some initial learning overhead, especially for developers not familiar with annotation-based configuration and asynchronous programming.
  • Verbose Error Handling
    Error handling in Retrofit can be verbose and repetitive if not done correctly, requiring custom solutions for efficient handling of common HTTP errors.
  • Larger APK Size
    Including both Retrofit and its dependencies, such as OkHttp and various converters, can increase the size of your APK, which might be a concern for developers optimizing for smaller app sizes.
  • Complex Configuration for Advanced Use Cases
    For more complex scenarios like custom request/response logging, interceptors, and parsers, configuration can become cumbersome and less straightforward.
  • Default Lack of Built-In Caching
    While OkHttp supports caching, Retrofit does not provide built-in caching out of the box. This requires additional configuration to implement client-side caching effectively.
  • No Built-In WebSocket Support
    Retrofit is mainly designed for RESTful APIs and does not natively support WebSocket communication, requiring additional libraries for such use cases.

  • 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 / 15 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 / 20 days ago

  • WordPress and Components
    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

  • Energy-Efficient Schema-Driven Development with Spring WebMVC/WebFlux
    At first, I thought it was just a knockoff of Retrofit (sorry...), but it turns out you can also use it as a controller interface. The *Exchange annotations in the earlier example come from this HTTP Interface. - Source: dev.to / 15 days ago
  • Using Retrofit Interceptors to check network connection in Android and testing it
    From this point on, I will assume, you have a basic understanding of Retrofit. To get the most out of this tutorial I would actually suggest you have a retrofit client already implemented in your application. - Source: dev.to / over 1 year ago

  • Show HN: Turn Your APIs into Swift Protocols
    Hey HN! If you're a fan of Swift you may have noticed that with WWDC 2023 came the (beta) release of macros. They're super powerful and expressive! I've been wishing Swift had a [Retrofit](https://square.github.io/retrofit/) style API definition library for years, and with macros it seemed like this was now possible. I'd like to show you all Papyrus, a library that turns your APIs into type-safe Swift protocols.... - Source: Hacker News / almost 2 years ago
