react-router-redux really needs a custom reducer?

[remojansen]

The docs say the following:

react-router-redux routeReducer does not work with Immutable.js. 

However, it seems to be supported.

Can you guys please clarify this?

Thanks!

@remojansen The issue that you have referenced to says:

Closing because I just saw the 3rd argument to syncReduxAndRouter method allowing you to pass in a function to select the routing state.

Which is exactly what the docs tell you do to: https://github.com/gajus/redux-immutable/tree/ac78103fc6939ef24c713f5a765f1b7187b9891c#using-with-react-router-redux

Are you talking about reducer specifically?

I do not see how react-router-redux reducer can work with Immutabe.js data (https://github.com/reactjs/react-router-redux/blob/5f9b7ec3b2fa7e54a581b220e75aec23005b67ff/src/index.js#L36-L42):

export function routeReducer(state = initialState, { type, payload: location }) {
    if (type !== UPDATE_LOCATION) {
        return state
    }

    return { ...state, location }
}

I just saw that syncReduxAndRouter is now syncHistory. I get it now 😄 thanks for the help!

If you really want that part of the state to be immutable you can write your own reducer that does the same, and pass something like state => state.get('routing').toJS() to that function.
