A library that provides null implementations for various PSRs remember that those don't do anything. I'd recommend to use them only if you are really sure you don't want something implementing the specific interface, or as a dev-dependency.

PSR-3 - psr/log

While psr/log for example includes a Null implementation (NullLogger), the psr/log package itself will not satisfy a psr/log-implementation requirement, hence this package provides Devedge\Log\NoLog. If you require this package the dependency will be full filled.

You can use $logger = new Devedge\Log\NoLog; to create a psr compliant Null Logger.

PSR-6 - psr/cache

The Pool is instanciated by doing: $pool = new Devedge\Cache\NoCachePool();
