A Nice To-Do List App with Angular.js

Description:

An Angular.js based to-do list / task manager web app which allows you to add, delete and categorize the tasks in a nice clean user interface. Built by AARON COCHRAN.

How to use it:

Add the Font Awesome 4 in the head section of your page. Font Awesome 4 is required for the App UI icons.

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">

Build a to-do list web app following the Html structure like this.

<div ng-app="TaskManager">
  <div class="container">
    <div class="content" ng-controller="taskController">
      <h1>To-do List App</h1>
      <p class="tagline">an angularJS todo app</p>
      <form>
        <div class="inputContainer">
          <input type="text" id="description" class="taskName" placeholder="What do you need to do?" ng-model="newTask">
          <label for="description">Description</label>
        </div>
        <div class="inputContainer half last"> <i class="fa fa-caret-down selectArrow"></i>
          <select id="category" class="taskCategory" ng-model="newTaskCategory" ng-options="obj.name for obj in categories">
            <option class="disabled" value="">Choose a category</option>
          </select>
          <label for="category">Category</label>
        </div>
        <div class="inputContainer half last right">
          <input type="date" id="dueDate" class="taskDate" ng-model="newTaskDate">
          <label for="dueDate">Due Date</label>
        </div>
        <div class="row">
          <button class="taskAdd" ng-click="addNew()"><i class="fa fa-plus icon"></i>Add task</button>
          <button class="taskDelete" ng-click="deleteTask()"><i class="fa fa-trash-o icon"></i>Delete Tasks</button>
        </div>
      </form>
      <ul  class="taskList">
        <li class="taskItem" ng-repeat="taskItem in taskItem track by $index" ng-model="taskItem">
          <input type="checkbox" class="taskCheckbox" ng-model="taskItem.complete" ng-change="save()">
          <span class="complete-{{taskItem.complete}}">{{taskItem.description}}</span> <span class="category-{{taskItem.category}}">{{taskItem.category}}</span> <strong class="taskDate complete-{{taskItem.complete}}"><i class="fa fa-calendar"></i>{{taskItem.date | date : 'mediumDate'}}</strong> </li>
