Optimistic UI updates after mutations

We can notice that there is a lag when users create a todo. We can also create UIs where the UI updates optimistically, assuming that the mutation will be successful.

To enable toggling between completed states, and to delete todos let's use optimistic updates when we run mutations!

We will learn the following concepts:

• Creating a GraphQL mutation
• Using the useMutation React hook
• Integrating Optimistic UI Updates
• Capturing loading/finished/error states

Let's get started!
