Let's say I work in a group and somebody else did
composer update and pushed changed
composer.lock file. I pulled it and now I have to do update too, to match the files from changed lock file.
In symfony I would delete vendor dir and run
composer install. But in drupal not all files are in vendor dir.
What is the best workflow in this case? Should I manually delete old vendor files (what dirs exactly?) or there is some composer command that will do all the work for me - check current vendor files with versions from composer.lock file and update what has to be updated?
