The inclusive design of a todo list interface is, however, framework agnostic. As a developer researching technology for a new project, it enables you to find the most intuitive and ergonomic choice for your needs. TodoMVC compares and contrasts todo app implementations of popular MV* frameworks including Vue.js, Angular.js, and Ember.js. Adding and removing items from todo lists demonstrates the immediacy of the single-page application view/model relationship. The first Angular.js example I ever read was a todo list. Let’s add some more state! Up in our constructor, we’ll add our list in the state.Inclusive Components book is now available, withĪccording to tradition, each new javascript framework is put through its paces in the implementation of a simple todo list app: an app for creating and deleting todo list entries. Now on our form, we can type in items but we don’t really have a list yet. Now inside of InputForm.js, we have a handle to this method as props.handleItemInput. This is how props are passed down to children components. You’ll notice that on our InputForm component in App.js we changed onClick to handleItemInput. const M圜omponent = (props) => from "react" These are simple functions that return JSX and receive properties (props). These components are reusable and composable and can manage their own private state. React describes the virtual DOM using components using JSX which is sort of a hybrid of Javascript and HTML. It will hold a virtual view in memory and only re-renders particular parts of the virtual DOM through the state when it is needed instead of re-rendering the entire page every time. We describe how we want the interface to look and React takes care of the how. React uses something called a Virtual DOM. Now a little background on React… VIRTUAL DOM Once you have this installed, open chrome dev tools and you should see a tab labeled “React.” This is where you can inspect your React components and it makes debugging a lot easier. Now one last step before we dive into the code and that is to install React Developer Tools which you can grab here.
