前言 在初步了解Redux中间件演变过程之后,继续研究Redux如何将中间件结合.上次将中间件与redux硬结合在一起确实有些难看,现在就一起看看Redux如何加持中间件. 中间件执行过程 希望借助图形能帮助各位更好的理解中间件的执行情况. redux如何加持中间件 现在是时候看看redux是如何将中间件结合了,我们在源码中一探究竟. * @param {Function} [enhancer] The store enhancer. You may optionally specify it
If you have props and actions, you want one component to access those props and actions, one solution is pass those from parent to this component. But one problem for this solution is if the there are many nested component between, you need to pass t
