Counter example:

import { createConnect } from 'corvid-redux';
import { createStore } from 'redux';

function reducer(state = 0, action) {
  switch (action.type) {
    case 'INCREMENT':
      return state + 1;
    case 'DECREMENT':
      return state - 1;
    default:
      return state;
  }
}

let store = createStore(reducer);
let { connect, pageConnect } = createConnect(store);

pageConnect(() => {
  connect(state => ({ text: `${state}` }))($w('#counter'));
  $w('#increment').onClick(() => store.dispatch({ type: 'INCREMENT' }));
  $w('#decrement').onClick(() => store.dispatch({ type: 'DECREMENT' }));
});

TodoMVC example:

    { _id: `${++counter}`, description: 'Task 1', completed: false },
    { _id: `${++counter}`, description: 'Task 2', completed: true },
    { _id: `${++counter}`, description: 'Task 3', completed: false }
  ]
};

function rootReducer(state = initialState, action) {
  switch (action.type) {
    case 'ADD_TODO':
      return Object.assign({}, state, {
        tasks: [
          ...state.tasks,
          { _id: action.id, description: action.text, completed: false }
        ]
      });
    case 'EDIT_TODO':
      return Object.assign({}, state, { editMode: action.id });
    case 'TOGGLE_TODO':
      return Object.assign({}, state, {
        tasks: state.tasks.map(todo =>
