🔍 Usage

A todo example

import * as aar from 'redux-aar';

interface ITask {
  done?: boolean;
  name: string;
}

interface IUpdateTask {
  index: number;
  task: ITask;
}

interface IState {
  todos: ITask[];
}

const initialState = (): IState => ({ todos: [] });
const createAction = aar.prefix('todos');
const add = createAction<ITask>('add');
const complete = createAction<number>('complete');
const remove = createAction<number>('remove');
const update = createAction<IUpdateTask>('update');

const reducer = aar.createReducer(initialState());

reducer
  .on(add, (state, todo) => {
    return { todos: state.todos.slice().concat(todo) };
  })
  .on(complete, (state, index) => {
    const todos = state.todos.slice();
    const todo = state.todos.slice()[index];

    todo.done = true;

    return { todos };
  })
  .on(remove, (state, index) => {
    return { todos: state.todos.filter((_, i) => i !== index) }
  })
  .on(update, (state, todo) => {
    const todos = state.todos.slice();

    todos[todo.index] = todo.task;

    return { todos };
  })
;

const store = redux.createStore(redux.combineReducers({
  todos: reducer.reduce(),
}));

store.dispatch(add({ name: 'foo' })); // todos length is 1
store.dispatch(add({ name: 'bar' })); // todos length is 2
store.dispatch(add({ name: 'baz' })); // todos length is 3

store.dispatch(remove(1)); // removes task { name: 'bar' };

store.dispatch(update({ index: 0, task: { name: 'helloworld' } }));  // task at index 0 is { name: 'helloworld' };

store.dispatch(complete(0)); // task at index 0 is { name: 'helloworld', completed: true };
