22. Common
Problems and Solutions with
Drupal + Composer
FAQ

23. VENDOR
How do I deploy a Drupal codebase if the `vendor` directory isn't in the codebase?

24. CKEditor
I need to put a library (e.g. CKEditor for Webform) in the `libraries` directory, and not
in `vendor`. Is this even possible with Composer?

25. NON-Packagist
One frontend library I need to add to my site (for a module, not a theme) is not on
Packagist. How can I `composer require` it without it being on Packagist?

26. D7 / D8
What's the best way to start building the codebase
for a new Drupal 8 (Drupal 8) website?

27. */modules
If I have a multisite installation,
how can I put certain modules in one `sites/site-a/modules` directory,
and others in another `sites/site-b/modules` directory?

28. UI
Using the command line to install modules is a lot to ask.
Isn't there some sort of UI I could use?

29. version conflict
What happens if there are dependencies required by two modules or core and a
module, and there's a conflict with version requirements?

30. custom module
How can I include libraries and shared modules that
I made for my own sites (they're not on Packagist)?

31. make file
I have a Drush make file for my site.
Can I easily convert this to a `composer.json` file?

32. composer.json
I set up my Drupal 8 site by downloading archives from Drupal.org and copying them
into the codebase. How can I convert my codebase to use a `composer.json` file?

33. `^` and `~`
What is the difference between `^` and `~` in version requirements, and should I use
one over the other?

34. composer update
When I run `composer update` a lot of weird things happen
and everything is updated, even if I don't want it to be updated.
Is there a way I can just update one module at a time?

35. composer install
When I run `composer install` on my production server, it runs out of memory.
How can I avoid this issue?

36. security
For security reasons, I need to verify that the code
I'm running in production wasn't hacked or modified.
How can I do this if I'm using Composer to manage my dependencies?

37. re-cloning
I totally screwed up some of the dependencies on my site while I was tinkering with
them. Is there any way to 'nuke' all the things in my codebase that Composer manages
so I can do a fresh `composer install` and get them back into the correct state (short of
deleting my entire codebase and re-cloning my site locally)?

38. composer.lock
My team constantly battles with `composer.lock` file merge conflicts.
How can we avoid this painful experience?

39. tips
Do you have any other tips for
making Composer use easier and more delightful?
