Module 7 Introduction

In our last module, we gave our client the ability to make a request to our API . However, we haven't been able to display any information in our UI just yet. In this module, we're going to use React Hooks to display data in our UI as well as handle our GraphQL API request. But what is a React Hook? Well React Hooks are just functions that allow components to hook into React- specific features. In this module, we'll introduce and explain what React Hooks are. Use React's use State Hook to keep track of component state. Use React's use effect hook to help make our GraphQL query when our component first mounts. Create our own custom use query hook that consolidates the functionality to make a query when a component mounts. Trapellate a refetch property from our use query hook to help our components retrigger a query after the component has already been mounted. Retrieve the loading and error status of our query made with the use query hook . Create a use mutation hook that provides a request function to conduct mutations. And finally, use React's use a reducer hook to recognize a different way to handle state and state changes in our custom hooks. (upbeat music)
