⚙️ redux-data-router 🔩

redux-data-router is a clean-room spiritual successor to projects like redux-first-history.

You only need to bring your React Router v6 data router, no need to manage a history object (or use UNSTABLE_ methods 😄)

Usage with router

import {createEnhancer, reducer} from 'redux-data-router';

// Create your data router like normal.
const router = createBrowserRouter(routes);
// Install the router reducer and enhancer.
const store = configureStore(
  reducer: {router: reducer}, // Install the reducer at the 'router' slice by default.
  enhancers: [createEnhancer(router)],
);

Redux is now connected to React Router! Yes, that's it.

Backwards-compatible

Effort has been made to keep the history action types working. redux-data-router exports all the actions you know and love:

dispatch(back());
dispatch(forward());
dispatch(go(2));
dispatch(goBack(2));
dispatch(goForward());
dispatch(push('/', state || {}));
dispatch(replace('/about'));

There is a new navigate action that is more semantically in line with how the modern router actually works:

dispatch(navigate('/about'));
dispatch(navigate('/about', {replace: true}));
dispatch(navigate(2));

Under the hood

History actions are casted to an equivalent navigate action. See: actions.js

Does this support time-travelling?

Yes. 😁 Router navigation is a side-effect of every location state change.

Configuration

createEnhancer takes an optional options object after your router:

{
  // The key used for the router slice.
  key: 'router',
}

For example, the introduction could have been configured differently for your unique state structure:

const store = configureStore(
  reducer: {FOO_BAR: reducer},
  enhancers: [createEnhancer(router, {key: 'FOO_BAR'})],
);

How it works

Up to now, libraries have been handling a history object to synchronize Redux state with React Router. This approach is no longer practical with current (February 2024) React Router data router semantics.

All is not lost, however! Instead of history.listen, we have a new API: router.subscribe. redux-data-router subscribes to changes through this channel to continuously synchronize the Redux state with the router state.

Is this a real single source of truth?

Probably not. React Router's internals aren't always easy to get into, and there may even be issues with the approach taken here. If e.g. the internal updateState API were made public, we might be able to become a true SSOT.
