Usage

Redux lite action solves issues that you need to define redux action names mutation functions separately. redux-lite-action whats to simplify that process in just writing the mutation functions which can be used as a action.

For example lets create a simple reducer which couple actions.

Reducer file.

import { combineActions, createReducerAction } from 'redux-lite-action';
 
interface Reducer {
  a: boolean;
  b: boolean;
  c: boolean;
}
 
interface PayloadA {
  a: boolean;
}
 
interface PayloadB {
  b: boolean;
}
 
const initialState: Readonly<Reducer> = {
  a: false,
  b: false,
  c: false,
};
 
export const mutationActionA = createReducerAction(
  // name your action function which will be used as a action name witch 
  // id prefix in front of name function name, this will prevent same action names
  // when function name is duplicated 
  function actionMutationA(store: Reducer, payload: PayloadA) {
    return { ...store, a: payload.a };
  },
);
 
export const mutationActionB = createReducerAction(
  function actionMutationB(store: Reducer, payload: PayloadB) {
    return { ...store, b: payload.b };
  },
);
 
// you can not pass payload then it will be treated as undefined
// and then when calling action you will not need to pass argument.
// also note that name cal be passed as a parameter
export const mutationActionC = createReducerAction(
  (store: Reducer) => {
    return { ...store, c: true };
  },
  'actionMutationC',
);
 
export const reducer = combineActions(initialState, [
  mutationActionA,
  mutationActionB,
  mutationActionC,
]);

Some point here you use your action.

import { 
  mutationActionA, 
  mutationActionB,
  mutationActionC,
} from './reducer';
 
dispatch(mutationActionA({ a: true }));
dispatch(mutationActionB({ b: true }));
// since payload is not defined then we do
// not need it to pass as a param
dispatch(mutationActionC());
