A unidirectional data flow pattern developed by Facebook for React applications
Core Idea: Flux is an application architecture pattern developed by Facebook that enforces unidirectional data flow to manage application state in React applications.
Key Elements
- Dispatcher: Central hub that manages all data flow in a Flux application
- Stores: Containers for application state and logic
- Views: React components that render data from Stores
- Actions: Payloads of information that send data from the application to the Dispatcher
Implementation Process
- User interacts with a View
- View propagates an Action through a central Dispatcher
- Dispatcher sends Actions to appropriate Stores
- Stores update their state based on Actions
- Views respond to changes from Stores
Principles
- Unidirectional data flow
- Centralized control with the Dispatcher
- Multiple stores for different domains
- Improved predictability compared to MVC Architecture
Origins and Development
- Developed at Facebook to solve scaling issues in their applications
- Created to address problems of bidirectional data flow in traditional MVC Architecture
- Publicly announced in 2014 at Facebook's F8 developer conference
- Designed specifically to work with React's declarative programming model
