HTTP/AJAX

Topics:

• axios package
• AJAX
• Promises

Instructions

1. Run yarn install or npm install inside the root directory of this project1Run yarn start or npm start to start the server.
2. The provided server returns a list of friends when a GET request is made to http://localhost:5000/friends.
3. In a separate terminal window, run yarn create react-app friends to create your starter React application.
4. CD into friends and run yarn add axios react-router-dom or npm install --save axios react-router-dom to include those dependencies in your project. You'll need react router for the stretch problems
5. Still inside your friends folder, run yarn start or npm start to fire up your React Dev Server.
6. Inside your React application, create a component to display the list of friends coming from the server.
7. Add a form to gather information about a new friend.
8. Add a button to save the new friend by making a POST request to the same endpoint listed above.
9. Each friend should have the properties listed below.
10. Implement Update and Delete functionality.
    • for update pass the friend id as a URL parameter, and the information you want to update about the friend inside the body. You can build a new form in the UI for this, or, if you set it up correctly, reuse the form you made for the POST request.
    • for delete, add a delete button, or an x icon to each friend that will delete the friend when you click it. In the request url, pass the friend id as a URL parameter.

For reference,

{
  name: should be a string,
  age: should be a number,
  email: should be a string,
}

Stretch Problems

1. Separate the list of friends and the new friend form into different components, and use the appropriate React Router to build routes for the proper aspects of your components to be revealed separately.
2. Style the friends list, the input field, and make everything look nice.
3. Expand the number of properties that you put on each friend object.
4. Feel free to remove the dummy data on the server or modify it in any way.
