• React's Lifecycle
• Create React App
• npm and yarn
• JSON
• more on state, and sophisticated data
• this.setState
• props
• Flexbox
• className

• Steps to get up and running

  • Step 1: fork and clone this project and cd into it.
  • Step 2: run npm install create-react-app -g to install CRA locally.
  • Step 3: run create-react-app react-friends.
  • Step 4: move the people.js file from this repo into the src directory inside of your new react-friends project.
  • Step 5: cd into react-friends and run npm start or yarn start and navigate to localhost:3000.

• App/PeopleList Set Up

  • Step 1: inside of App.js create your constructor function, (don't forget to super()) and add a state object to it. Inside that state object define an array called People.
  • Step 2: import people data in like so: import { people } from './people.js (if you haven't included people in your src directory this wont work); _ Step 3: create a method called componentDidMount and set the people data on state.
  • Step 4: create your PeopleList as a function component and import it in as: import {PeopleList} from './PeopleList'.
  • Step 5: pass your People data down to PeopleList and render out the People List <PeopleList people={this.state.People} />.
  • Step 6: for each person in PeopleList render out the first_name and last_name and email.
  • Step 7: Go to town styling your components!

• Styling Components

  • Step 1: create a file called PeopleList.css and go to town styling! Try and center each person on the screen.
  • Step 2: import PeopleList styles into PeopleList.js as `import './PeopleList.css'; to grant you access to the className references.
    • Hint: Delete the styles in the app.css and index.css files and do it on your own! Make things look pretty!
