Tutorials

Now let's talk with the todo-list as a example.

First, we need create the Todo reducer that can receive the message relative to 'Todo'.

import { Reducer } from 'flux-reducer';

class TodoReducer extends Reducer({
  name: '',
  detail: '',
  isCompleted: false,
}) {
  changeName(name) {
    this.trigger(this.set('name', name));
  }
};

The UI can send the 'changeName' to TodoReducer to change the Todo name. The trigger will broadcast the new reducer to all subscribers.

Then, we need create Todos reducer that can respond to Todo collection related actions.

import { ArrayReducer } from 'flux-reducer';

class TodosReducer extends ArrayReducer {
  constructor() {
    super(...arguments);
    this.monitorAllValues();
  }

  addTodo(todo) {
    this.trigger(this.push(new TodoReducer(todo)));
  }
}

We need invoke TodosReducer's' addTodo method to add the new Todo instance.

Now, we can subscribe to TodosReducer to get the new state.

let todosReducer = new TodosReducer;
todosReducer.subscribe((newReducer) => {
  console.log('the todos have changed.');
});

todosReducer.addTodo({
  name: 'new todo',
});

Invoke this code segment, the log information will show in the terminal.
