The reason why Composer feels slow when installing or updating dependencies is mainly due to the superposition of factors such as dependency parsing, metadata acquisition, automatic loading optimization and environment configuration. 1. Relying on parsing uses backtracking algorithms, and multiple version combinations need to be tried. The larger the project and the more time-consuming the constraints, it can be alleviated by simplifying composer.json and using specific version constraints; 2. By default, the metadata obtained from Packagist may be affected by the network, and can be used to use mirrors or DNS acceleration; 3. Automatic load generation and script execution will also increase overhead, and it is recommended to disable autoload and scripts as needed; 4. Use old versions of Composer or improper PHP settings (such as memory limits, OPcache not

The steps to create a Git repository for package are as follows: 1. Run gitinit in the project root directory to initialize the local repository, execute gitadd. Add files, and then use gitcommit-m "Initialcommit" to submit the initial version; 2. Log in to GitHub and other platforms to create a new remote repository, use gitremoteaddorigin to associate the remote repository, push code through gitpush-uoriginmain and set default branches; 3. Create a .gitignore file to exclude files that do not need to be tracked, such as node_modules/, .env, etc., and you can refer to the official GitHub template; 4.

Creating a PHP package requires four steps: setting the project structure, creating a composer.json file, version control and tagging, and publishing to Packagist or private repository. 1. The project structure should include src/ directory storage code, composer.json configuration metadata, and README.md description documents. 2.composer.json needs to define name, description, dependency, and automatic loading rules, such as using the PSR-4 standard to map the namespace. 3. Use Git to label version management, follow the semantic version number specification and update composer.json simultaneously. 4. You can choose to publish the package to Packagist for public installation, or build private through Satis

Common events for Composer plug-in include init, command, pre-file-download, post-install-cmd, post-update-cmd, pre-autoload-dump and post-autoload-dump. Init is used to initialize configuration and register repositories; command is used to log or verify before command execution; pre-file-download can be used to modify download URLs or use cache; post-install-cmd and post-update-cmd are used to run cleanup or deployment tasks after installation or update; pre-autolo
