The React component lifecycle provides a list of methods that can be used to execute code at certain moments in a component's lifetime. Looking at the mounting lifecycle, Eve installs fetch, which is a way to grab data from an API. Connect to the API and load data on members. Use methods like componentWillMount and componentDidMount to enhance the app.

The next state variable that we want to set up…is loading, and we want to set it equal to false.…So, the initial state of our application…will have loading as false,…and then we're going to use another method that is going…to trigger that loading process.…The way that we're going to load this data is using fetch.…Now, since I included this for you already,…we don't have to NPM install it.…
