Let's get you some practice with adding a mutation feature.
Here's what you'll need to do:
- Use GraphQL Playground to construct the
deleteHabitmutation with the correct variables. - Add the mutation and the
useMutationhook toHabit.js. - Add a button next to each habit item to call the mutation.
- Don't forget about the
errorandloadingstates!
I'll show you what I came up with in the next video.
