A deep dive into mutations in TanStack Query

TanStack Query, formerly known as React Query, is a powerful library for managing data state in React applications without relying on a global state. It offers two primary hooks: useQuery for fetching data and useMutation for creating, updating, or deleting data on a server. TanStack Query simplifies state management with features like caching, synchronization, and query invalidation, making it easier to handle asynchronous data requests and manage side effects. The library supports optimistic updates, allowing developers to update the UI before server confirmations, and provides callback functions for handling mutation lifecycles. Through examples, the text illustrates how to implement queries and mutations, including performing multiple mutations in parallel and updating cached data directly. TanStack Query's intuitive approach and zero-configuration setup make it an appealing choice for React developers seeking efficient state management solutions.
