Dependency management

It’s possible to build a Nextcloud app with existing software packages.


You can add 3rd party php packages with Composer. Composer will download the specified packages to a directory of your choice, typically to /vendor. In order to benefit from Composer’s autoloader, you’ll want to add a require_once to the register method of your Application class in the bootstrapping code of your app.


Be careful with which packages you add to an app. Php can not load two version of the same class twice, hence there can be conflicts between Nextcloud Server and an app or between two or more apps if they ship the same library. So try to keep the number of libraries to a minimum.
