Documentation of generated Redux code for reducers.
The helloWorld/reducers/index.jsx
example that results from running the generator with the Redux option may be slightly confusing because of its simplicity. For clarity, what follows is a more fleshed-out example of what a reducer might look like:
import usersReducer from './usersReducer';
import blogPostsReducer from './blogPostsReducer';
import commentsReducer from './commentsReducer';
// ...
import { $$initialState as $$usersState } from './usersReducer';
import { $$initialState as $$blogPostsState } from './blogPostsReducer';
import { $$initialState as $$commentsState } from './commentsReducer';
// ...
export default {
$$usersStore: usersReducer,
$$blogPostsStore: blogPostsReducer,
$$commentsStore: commentsReducer,
// ...
};
export const initialStates = {
$$usersState,
$$blogPostsState,
$$commentsState,
// ...
};
