React app using the SpaceX API

This app is based on Traversy Media's tutorial on GraphQL with React and Apollo, with some additions:

• The SpaceX API version 4 is used instead of version 3.
• React Hooks are used to manage state and context, namely useState and useContext, as well as Apollo queries useQuery.
• Launches list is filtered by launch date.
• The option to filter launches by success or fail property.
• Use of createContext to manage the filter options.

The app is deployed to heroku here.
