• Understand how to communicate between client and server using fetch, and how the server will process the request based on the URL, HTTP verb, and request body
• Debug common problems that occur as part of the request-response cycle

Just like the last lesson, we've got code for a React frontend and Rails API backend set up. This time though, it's up to you to use your debugging skills to find and fix the errors!

To get the backend set up, run:

$ bundle install
$ rails db:migrate db:seed
$ rails s

Then, in a new terminal, run the frontend:

$ npm install --prefix client
$ npm start --prefix client

Confirm both applications are up and running by visiting localhost:4000 and viewing the list of toys in your React application.

In this application, we have the following features:

• Display a list of all the toys
• Add a new toy when the toy form is submitted
• Update the number of likes for a toy
• Donate a toy to Goodwill (and delete it from our database)

The code is in place for all these features on our frontend, but there are some problems with our API! We're able to display all the toys, but the other three features are broken.

Use your debugging tools to find and fix these issues.

There are no tests for this lesson, so you'll need to do your debugging in the browser and using the Rails server logs and byebug.

Note: You shouldn't need to modify any of the React code to get the application working. You should only need to change the code for the Rails API.

As you work on debugging these issues, use the space in this README file to take notes about your debugging process. Being a strong debugger is all about developing a process, and it's helpful to document your steps as part of developing your own process.
