breaks Redux store.replaceReducer - Last 50 actions RE-APPLIED

[crobinson42]

When you invoke store.replaceReducer(newReducer) the last 50 (maxage default param) actions are applied/run-through the store.

This has the potential to break a lot of applications, mine in particular where several of the last 50 actions are using http or socket middleware for async actions. During the state of my application I use code-splitting which involved heavy utilization of store.replaceReducer anytime a new module is loaded I register a new reducer dynamically thus invocation of replaceReducer.

Is this intended to be a feature or a potential bug? Thanks!

Any update on this one? Happy to help if possible.

When you use store.replaceReducer the effect will be the same as for hot-reloading, where the extension is recomputing all the history again. To avoid that set shouldHotReload parameter to false.
