Integration Guide

The library comes with the support of both compile-time and runtime-time dependency injection. Although the use of runtime-time injection is preferred, both options are equal and fully implemented.

Add Library into the Project

// enable Play cache API (based on your Play version)
libraryDependencies += play.sbt.PlayImport.cacheApi
// include play-redis library
libraryDependencies += "com.github.karelcemus" %% "play-redis" % "2.1.1"

Runtime-time Dependency Injection

You must enable the redis cache module in application.conf:

# enable redis cache module
play.modules.enabled += "play.api.cache.redis.RedisCacheModule"

It will bind all required components and make them available through runtime DI according to the configuration.

Compile-time Dependency Injection

To use compile-time DI, mix play.api.cache.redis.RedisCacheComponents into your BuiltInComponentsFromContext subclass. It exposes cacheApi method accepting a redis instance (or just cache name, if configured) and returns an instance of RedisCaches encapsulating all available APIs for this particular cache. Then you can access and expose them yourself. Next, it provides a few methods to override and provide customized configuration. For more details, see directly RedisCacheComponents source.

   // 'play' is the name of the named cache
   // (play is default name of the default cache)
   //
   // the 'play' literal is implicitly converted into
   // the instance but has to be configured in 'application.conf'
   val playCache: RedisCaches = cacheApi( "play" )

   // expose `play.api.cache.redis.CacheAsyncApi`
   val asynchronousRedis = playCache.async
