Flux vs redux-query: What are the differences?

# Introduction

Flux and redux-query are two popular state management libraries used in web development. While both serve the purpose of managing application state, they have some key differences that make them unique in their own ways.

1. **Architecture**: Flux follows a unidirectional data flow pattern where actions are dispatched to stores, which then update the state and trigger re-rendering of components. Redux-query, on the other hand, integrates with Redux and adds the ability to handle data fetching and caching alongside Redux's state management.

2. **Data Fetching**: Flux typically relies on separate data fetching libraries or utilities to handle async data retrieval, while redux-query provides built-in functionality to handle data fetching, caching, and management of remote data sources within the Redux ecosystem.

3. **Normalization**: Redux-query has built-in support for normalizing API response data, making it easier to manage complex data structures and relationships within the application state. Flux, on the other hand, might require additional handling or normalization of data within the stores.

4. **Query Management**: Redux-query offers a declarative way to define and manage data queries within the Redux state, making it easier to reason about and manage complex data fetching logic. Flux, on the other hand, might require more manual handling of querying and updating data within the stores.

5. **Community Support**: Redux-query, being a part of the Redux ecosystem, benefits from a larger community and ecosystem of plugins and tools that can enhance its functionality. Flux, while still popular, might have a smaller community and fewer resources available for support and extension.

6. **Learning Curve**: The learning curve for Flux might be steeper due to its more flexible and manual approach to managing state, whereas Redux-query, being more opinionated and integrated with Redux, might have a gentler learning curve for developers already familiar with Redux.

In Summary, Flux and redux-query differ in their architecture, data fetching capabilities, normalization support, query management, community support, and learning curve for developers.
