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.

ReactiveX features and specs

  • Asynchronous Programming
    ReactiveX simplifies asynchronous programming by providing a consistent API for handling sequences of events or data streams. This can lead to cleaner and more maintainable code.
  • Composability
    With ReactiveX, you can easily compose multiple operations on streams using operators, leading to expressive and declarative code. This helps in building complex data pipelines with ease.
  • Error Handling
    ReactiveX provides robust mechanisms for error handling in asynchronous flows, making it easier to build resilient applications that can gracefully handle failures.
  • Backpressure Handling
    ReactiveX offers built-in support for backpressure, enabling systems to handle varying rates of data production and consumption efficiently.
  • Language Support
    ReactiveX is available across multiple programming languages, including Java, JavaScript, Python, Swift, and more, making it a versatile choice for developers working in different ecosystems.
  • Community and Documentation
    ReactiveX has a strong community and extensive documentation, providing ample resources for learning and troubleshooting.

Possible disadvantages of ReactiveX

  • Learning Curve
    ReactiveX introduces a new paradigm for those unfamiliar with reactive programming, and the extensive set of operators can be overwhelming for beginners.
  • Performance Overhead
    The abstraction provided by ReactiveX can introduce performance overhead compared to lower-level approaches, which may be a concern for performance-critical applications.
  • Complexity in Debugging
    Debugging reactive streams can be challenging because of the asynchronous and declarative nature of the code, making it harder to trace issues.
  • Overuse
    There is a risk of overusing ReactiveX for scenarios where it might not be the best fit, leading to unnecessary complexity in simpler contexts.
  • Integration with Legacy Code
    Integrating ReactiveX with legacy codebases that are not designed around reactive principles can be cumbersome and may require significant refactoring.

  • 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 / 21 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 / 26 days ago
  • PHP Core Security Audit Results
    Dependencies are managed by Composer (like npm, cargo, etc) for more than 10 years now. https://getcomposer.org. - Source: Hacker News / 30 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

  • Kapper 1.3 supports flows - more Kotlin goodness
    Flows are a Kotlin API for asynchronous streams of data. They are similar to Rx Observables, but are simpler and more idiomatic to Kotlin. They are a great fit for asynchronous data processing, particularly for database operations where results may be large or processing needs to happen incrementally. This makes them a perfect addition to Kapper's existing coroutine support. - Source: dev.to / about 2 months ago
  • Hydro: Distributed Programming Framework for Rust
    It looks like a mixture between Akka (https://getakka.net/ less enterprisy than the Java version), which is based on the actor model and has a focus on distributed systems, and reactive libraries like rx (https://reactivex.io/). So maybe https://doc.akka.io/libraries/akka-core/current/stream/index.html is the best fit. - Source: Hacker News / 3 months ago
  • Haskell: A Great Procedural Language
    > Is there any parallel there Of course. Promise is a monad, .then is more or less equivalent to the >>= operator and await makes it look more imperative-ish just like <- in Haskell. Note that in JS you'll need to be inside an async function to use await, just like in Haskell you'll need to be inside the do notation to use <-. Otherwise, you'll need to play with .then just like you would need to play with >>= in... - Source: Hacker News / 4 months ago
  • Understanding DynamicData in .NET: Reactive Data Management Made Easy
    DynamicData is a .NET library that brings the power of reactive programming to collections. It is built upon the principles of Reactive Extensions (Rx), extending these concepts to handle collections like lists and observables more efficiently and flexibly. DynamicData provides a set of tools and extensions that enable developers to manage collections reactively, meaning any changes in the data are automatically... - Source: dev.to / about 1 year ago
  • What is your preferred asynchronous programming library?
    Another option is to use the RxJava library in Java. This library uses reactive programming principles to make it easy to write asynchronous and event-driven code. It's particularly well-suited for handling streams of data and allows you to write code that is both efficient and easy to read. Source: about 2 years ago
