  • 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.

  • Cursor Introduces Composer 2.5
    It's very confusing that they use the same name as the very well known PHP package manager, composer https://getcomposer.org/. - Source: Hacker News / 2 months ago
  • Composer is just a console application
    I'm embarrassed I never took the time to understand Composer until now. I have been preaching for a long time to start each PHP project with Composer, even when the project is not going end up on Packagist. - Source: dev.to / 2 months ago
  • Publishing a PHP monorepo to Packagist with splitsh-lite
    Waaseyaa is a monorepo. The root composer.json defines 43 subpackages under packages/, each referenced as a path repository with @dev constraints. During development, this is convenient. Composer resolves everything locally, and you never think about versioning. - Source: dev.to / 4 months ago
  • Peer dependencies in (P)NPM
    (P)NPM is an outlier in this behavior compared to package managers of other languages. With package managers like Composer (PHP), pip (Python) and NuGet (.NET) dependencies are by default peer dependencies. That means that in those package managers it is not possible to have multiple versions of the same dependency in your application1. - Source: dev.to / 8 months ago
  • Build a Robust RESTful API with PHP 8, from Scratch Course!
    Download from getcomposer.org and follow installation instructions. - Source: dev.to / 10 months ago
