To find dependent packages for a Composer JSON package, you can use the following methods:
1. Composer's require
and require-dev
sections
In your composer.json
file, look for the require
and require-dev
sections. These sections list the dependencies
required by your project. For example:
"require": {
"monolog/monolog": "^1.23",
"symfony/console": "^4.4"
},
"require-dev": {
"symfony/phpunit-bridge": "^4.4",
"doctrine/doctrine-fixtures-bundle": "^3.3"
}
In this example, monolog/monolog
and symfony/console
are required dependencies, while symfony/phpunit-bridge
and doctrine/doctrine-fixtures-bundle
are development dependencies.
2. Composer's composer.json
file
You can also use the composer
command to inspect the dependencies of a package. For example:
composer show --format=json <package-name>
Replace <package-name>
with the name of the package you're interested in. This command will output a JSON
representation of the package's metadata, including its dependencies.
3. Composer's composer.lock
file
The composer.lock
file is generated by Composer when you run composer install
. It contains a snapshot of the
dependencies required by your project at the time of installation. You can inspect this file to see the dependencies
required by your project.
4. Composer's why
command
Composer provides a why
command that can help you identify the dependencies required by your project. For example:
composer why <package-name>
Replace <package-name>
with the name of the package you're interested in. This command will output a list of packages
that depend on the specified package.
5. Package repositories
You can also inspect the package repositories (e.g., Packagist) to see the dependencies required by a package. For example, you can visit the Packagist page for a package and look for the "Requires" section.
By using these methods, you should be able to identify the dependent packages for a Composer JSON package.
