A tiny utility to create reducer maps for Redux that follows the priciples of
Flux Standard Action (FSA) and will enable you to handle errors as a first class
concept. No need to define separate action types like SOME_ACTION_SUCCESS and
SOME_ACTION_ERROR, but instead use FSA actions to represent errors is a simple
and straightforward manner.
import createReducer from 'create-reducer-map';
import { SOME_ACTION, ANOTHER_ACTION } from 'path/to/actionHandlers';
const initialState = {};
export default createReducer(initialState, {
[SOME_ACTION]: {
// Handles a basic FSA action.
next: (state, payload, meta) => state,
// Handles an FSA action that represents an error.
throw: (state, payload, meta) => state,
},
// Handles any FSA action.
[ANOTHER_ACTION]: (state, payload, meta) => state
});
// Basic FSA action
{
type: SOME_ACTION,
payload: {
text: 'Do something...'
}
meta: {
optional: 'Something else...'
}
}
// FSA action representing an error
{
type: SOME_ACTION,
payload: new Error(),
error: true
}
