Bulk delete todos - mutation

In this part of the tutorial, you will learn how to bulk delete all the existing completed todos by using GraphQL Mutations.

Let's define a graphql query to do a mutation into todos.

mutation clearCompleted {
delete_todos(where: {is_completed: {_eq: true}, is_public: {_eq: false}}) {
affected_rows
}
}

You will also need to pass in the values for the variables.

Try this mutation in GraphiQL against the application database to see what the response looks like.

Let's now integrate this graphql mutation into our react app.
