Error restoring data for key:todoList [ReferenceError: localStorage is not defined]

[jinaymehta25]

I am seeing this error in console and most probably that's happening on the node server side (isomorphic app). Is there a way to handle this?

[rt2zz]

yes this is a relatively easy fix

question though: how do you expect redux-persist to work on the server? are you expecting a noop?

[zalmoxisus]

Unless you do not store states on the server side, you don't need Redux Persist there. A solution could be to move store persisting in a separate module and import it only on the client side or to have 2 different implementations depending on the side. Like here.

@rt2zz : Yes something like noop. @zalmoxisus: I saw your solution, exactly how do you decide where is the app running?

[zalmoxisus]

In that example, I just add the environment flag to the second parameter of configureStore, but in case of an universal ("isomorphic") app it's even easier, you may just use, for example, process.env.isServer.

Using redux-persist as a noop wouldn't be a good solution, as it tries to persist new state on every action.

just released 1.4.5

no localStorage now console.errors with a useful message. In production it is a noop.

@zalmoxisus I do not think process.env.isServer is defined in most node environments. AFAIK the tyipical albeit indirect way to check if in node is https://gist.github.com/rt2zz/ac9eb396793f95ff3c3b
