Simple Play filter which introduces a random additional node to each Json object which is returned by the called Microservice.

The purpose of this is to ensure that calling clients of the microservice have not tightly coupled their service to the exact Json returned and are tolerant of additional, unexpected, fields. The intent is for this only to be run in development and not in production environments.


To use the filter create as per below and then add randomJsonFilter into your filters collection.

  lazy val randomJsonFilterConfig = Play.current.configuration.getConfig(s"$env.randomJsonFilter")
  lazy val randomJsonFilter = new RandomJsonFilter(randomJsonFilterConfig) with MicroserviceFilterSupport

The example below uses a config item based on the environment - e.g. Dev - so to enable the filter you would set:

Dev {
  randomJsonFilter.enabled = true
