Dynamically load sagas for code splitting in redux application












1















I am trying to integrate redux-saga into my react app. I am currently code splitting reducers by dynamically injecting it using replaceReducer when correct route is hit.I am adding a code snippet.



reducerRegistry.setChangeListener(reducers => {

    store.replaceReducer(combine(reducers));

});


I want to do the same with sagas but couldn't figure out a way to dynamically inject saga.

I tried to implement it like below and it seems to work.



export class SagaRegistry {

  constructor() {

    this._emitChange = null;

    this._sagas = {};

  }



  getSagas() {

    return { ...this._sagas };

  }



  register(name, saga) {

    if (this._sagas[name]) {

      return;

    }

    this._sagas = { ...this._sagas, [name]: saga };

    if (this._emitChange) {

      this._emitChange(saga);

    }

  }



  setChangeListener(listener) {

    this._emitChange = listener;

  }

}



const sagaRegistry = new SagaRegistry();

export default sagaRegistry;


And run saga like this.



sagaRegistry.setChangeListener(saga => {

  sagaMiddleware.run(saga);

});
