forces

Forces always come in pairs - known as "action-reaction force pairs."

It is basically the same concept as redux-modular-ducks but with a less loaded term in programming circles.

rules

A force:

1. MUST export default a function called reducer()
2. MUST export its action creators as functions
3. MAY export its action types as UPPER_SNAKE_CASE, if an external reducer needs to listen for them, or if it is a published reusable library

example

// message.js

const SHOW = 'my-app/message/SHOW';
const HIDE = 'my-app/message/HIDE';

export default function reducer(state = {}, action = {}) {
  switch (action.type) {
    // do reducer stuff
    default: return state;
  }
}

export function showMessage() {
  return { type: SHOW };
}

export function hideMessage() {
  return { type: HIDE };
}
