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.

KnockoutJS features and specs

  • Data Binding
    KnockoutJS offers a powerful two-way data binding mechanism, allowing for automatic synchronization between the model and the user interface. This reduces the amount of boilerplate code needed to manage data updates.
  • Declarative Bindings
    The library uses declarative bindings to connect the UI to the data model. This makes it easier to understand the structure of your UI without having to sift through complex JavaScript code.
  • Flexibility
    KnockoutJS is framework-agnostic, meaning it can be integrated with other libraries and frameworks such as jQuery and Angular, providing flexibility in application architecture.
  • Simplicity
    It's relatively easy to learn and use, especially for developers familiar with Model-View-ViewModel (MVVM) architecture.
  • Community Support
    Despite being a mature library, KnockoutJS has a solid community with ample documentation and plugins, which can be quite helpful for development and troubleshooting.

Possible disadvantages of KnockoutJS

  • Performance Issues
    For very complex applications or large datasets, KnockoutJS might lead to performance bottlenecks, since it doesn’t offer the same virtual DOM diffing optimizations as newer frameworks/libraries like React.
  • Steep Learning Curve for Complex Applications
    While it's simple for smaller projects, creating and managing more complex applications often involves a steeper learning curve and can lead to complex models.
  • Lack of Built-in Support for Modern Features
    KnockoutJS does not natively support some modern JavaScript features and patterns, such as ES6 modules or TypeScript, requiring additional configurations or libraries.
  • Decreasing Popularity
    As more modern frameworks like React, Angular, and Vue gain popularity, the use of KnockoutJS is declining, which might lead to a smaller community and fewer updates or improvements in the future.
  • Limited Official Tooling
    Compared to newer frameworks, KnockoutJS has less official tooling support for development, build processes, and testing, which can make project setup and maintenance more arduous.

  • 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 / 22 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 / 27 days ago

    Dependencies are managed by Composer (like npm, cargo, etc) for more than 10 years now. https://getcomposer.org. - Source: Hacker News / about 1 month 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

  • JSX over the Wire
    > Everything old is new again An age ago I took interest in KnockoutJS based on Model-View-ViewModel and found it pragmatic and easy to use. It was however at the beginning of the mad javascript framework-hopping marathon, so it was considered 'obsolete' after a few months. I just peeked, Knockout still exists. https://knockoutjs.com/. - Source: Hacker News / 26 days ago

  • The Best UI Libraries for Cross-Platform Apps with Tauri
    SolidJS and Tauri form another potent combination for creating performant, lightweight, and secure experiences. SolidJS is a reactive UI library that is similar to Svelte in the way it compiles away reactivity and updates the DOM directly, but it also incorporates a fine-grained reactivity system reminiscent of libraries like Marko, Knockout, and MobX. - Source: dev.to / almost 2 years ago
  • Why are signals still not so popular?
    People act like Signals are a new discovery. KnockoutJS was using them 13 years ago and other libraries used them before that. Source: almost 2 years ago
  • What is KnockoutJS and how is it relevant in Magento 2?
    Knockout JS is a Javascript library which uses the MVVM pattern to bind data to certain DOM elements. Within Magento, we usually define a View-Model (which is a .js file) and a Template (which is a .html file), and the data in the template file is bound to the view-model, meaning whenever the data in the view-model changes, the template file changes too.
