How to remove unused dependencies from composer?
I installed a package with composer, and it installed many other packages as dependencies.
Now I uninstalled the main package with composer remove packageauthor/packagename, but all the old dependencies were not removed. I expected composer to clean up and only keep packages that are required according to composer.json and their dependencies.
How can I force composer to clean up and remove all unused packages ?
The right way to do this is:
composer remove jenssegers/mongodb --update-with-dependencies
I must admit the flag here is not quite obvious as to what it will do.
Update
composer remove jenssegers/mongodb
As of v1.0.0-beta2 --update-with-dependencies is the default and is no longer required.
In fact, it is very easy.
composer update
will do all this for you, but it will also update the other packages.
To remove a package without updating the others, specifiy that package in the command, for instance:
composer update monolog/monolog
will remove the monolog/monolog package.
Nevertheless, there may remain some empty folders or files that cannot be removed automatically, and that have to be removed manually.
--prune
following commands will do the same perfectly
rm -rf vendor
composer install
composer install will automatically delete unused packages
Just run composer install - it will make your vendor directory reflect dependencies in composer.lock file.
In other words - it will delete any vendor which is missing in composer.lock.
Please update the composer itself before running this.

composer remove …'d, but forgot the--update-with-dependenciesuntil you stumble across this question — subsequent calls tocomposer removewon't kill all dependencies. You'll need to revert, composerinstall, thencomposer remove --update-with-dependenciesYou are using the deprecated option "update-with-dependencies". This is now default behaviour. The --no-update-with-dependencies option can be used to remove a package without its dependenciescomposer updateThumbs up to this answer to @LorenzMeyer
