React native + redux-persist:如何忽略键(黑名单)? [英] React native + redux-persist: how to ignore keys (blacklist)?

问题描述

我正在使用 redux-persist 存储我的设置，并希望忽略其中的一些设置，以便在每次重新启动时重置它们，例如崩溃后.

I'm storing my settings with redux-persist and would like to ignore some of them to have them reset on every restart, e.g. after a crashing.

可以将一个 reducer-name 数组添加为 blacklist 或 whitelist，但我想忽略特定的键，例如settings.isLoggedIn 而不是 settings.

It's possible to add an array of reducer-names as blacklist or whitelist, but I'd like to ignore specific keys, e.g. settings.isLoggedIn instead of settings.

// ...
function configureStore(initialState) {
    const store = createStore(
        RootReducer,
        initialState,
        enhancer
    );

    persistStore(store, {
        storage: AsyncStorage,
        blacklist: ['router', 'settings'] // works, 'settings.isLoggedIn' doesn't.
    }, () => {
        // restored
    });

    return store;
}
// ...

我是否必须创建另一个减速器或是否有人解决此问题?

Do I have to create another reducer or does anyone a solution to this problem?

提前致谢！

推荐答案

根据 文档，黑名单参数包含:要忽略的键(读取:reducers)"，因此恐怕无法实现您想要的行为.您可以尝试自己实现该功能，但我认为该包的代码库真正侧重于将减速器而不是属性列入黑名单(请参阅 this).恐怕唯一的解决方案是为您的非持久键创建一个单独的减速器(根据我的经验，这并不麻烦).

As per the documentation, the blacklist parameter contains: 'keys (read: reducers) to ignore', so I am afraid it is not possible to implement the behaviour that you want. You can try and implement that functionality yourself, but I think the codebase of the package is really focused on blacklisting reducers instead of properties (see this). I am afraid that the only solution is to create a separate reducer for your non-persistent keys (in my experience it is not much of a hassle).
