有关 createLogger的transformer选项

[GavinCLY]

const logger = createLogger({
collapsed: false, // auto-expand logged mutations
transformer (state) {
// transform the state before logging it.
// for example return only a specific sub-tree
return state.subTree
},
mutationTransformer (mutation) {
// mutations are logged in the format of { type, payload }
// we can format it any way we want.
return mutation.type
}
})

从文档中来看，transformer貌似是对console输出的state进行部分展示，例如我只输出state中的items对象，但在实际操作中并没有看到这样的效果。

是否需要将logger.js中的输出的部分修改成：
// 源码：console.log('%c prev state', 'color: #9E9E9E; font-weight: bold', prevState);

  console.log('%c prev state', 'color: #9E9E9E; font-weight: bold', transformer(prevState));
  console.log('%c mutation', 'color: #03A9F4; font-weight: bold', formattedMutation);
  console.log('%c next state', 'color: #4CAF50; font-weight: bold', transformer(nextState));

不知道是我对transformer的理解有误，还是这的确是漏了，忘不吝赐教

@yyx990803 Is this just being forgot to use transformer?
