Practicing react making a todo app

React Todo Exercise

A simple react todo application

Setup

git clone ...
cd react-todo
npm install
atom .
npm start

Step 1 - paint items from app state

• create initial state

{
  todos: [{
    id: 1,
    title: 'Pick Final Project',
    completed: false
  }, {
    id: 2,
    title: 'Plan Final Project',
    completed: false
  }]
}

• render state using map

Included is a module fun-fp you can use the map function from fun-fp or you can use the array map function, but the goal is to map over the todos and display them using the TodoItem component

Step 2 - add todo item

• create controlled input and submit form
• append new item to state

Step 3 - toggle complete

• create onToggle function
• pass to todo-item as prop
• if the item is completed add completed to the classname

Step 4 - edit todo item

• TodoItem needs its own state editText: this.props.todo.title

• TodoItem needs to handle the following events

  • handleEdit
  • handleChange
  • handleSubmit

• View Label should listen for double click event

  • onDoubleClick = this.handleEdit

• Edit Input should be controlled

  • value = this.state.editText
  • onChange = this.state.handleChange
  • onBlur = this.state.handleSubmit

• Implement editText, handleChange, handleSubmit on TodoItem Component

• Render method should change li className to editing if this.props.editing is not null

• App should pass the following props to TodoItem

  • editing = this.state.editing
  • onEdit = this.editTodo(todo)
  • onSave = this.saveTodo(todo)

• Implement editTodo and saveTodo on app component

Step 5 - delete item

• When the delete button is clicked we want to tell the app state to remove the item

Step 6 - show active item count

• reduce over todos and inc completed = false

Step 7 - filter active items and filter completed items and all items

• toggle viewState = 'active'
• on render filter todos based on viewState

Step 8 - clear completed

• handle completed click and filter todos and assign filtered list
