RTK Query (1/22)
What is RTK Query and why was it introduced?
Understanding RTK Query and Its Purpose in Redux Toolkit
RTK Query is a powerful data fetching and caching tool built into Redux Toolkit. It was introduced to simplify the process of managing server state — including fetching, caching, updating, and synchronizing data between a client and an API — while reducing the amount of boilerplate code typically required with Redux.
Why RTK Query Was Introduced
- To eliminate repetitive boilerplate code for async data fetching and state management.
- To provide built-in caching, invalidation, and automatic re-fetching of API data.
- To improve performance by avoiding unnecessary network requests and re-renders.
- To make integrating APIs with Redux applications faster, easier, and more consistent.
Example: Simple RTK Query Setup
RTK Query automates the complexities of API calls and state synchronization, allowing developers to focus on building features rather than managing network logic manually.
