Flux, in the context of technology, refers to the rate of flow of energy or particles through a given area or surface, typically measured in units like Weber (Wb) for magnetic flux and Lumen (lm) for luminous flux. In electronics, flux is a chemical cleaning agent, applied to metal surfaces before soldering, to remove oxides and promote adhesion. Flux helps facilitate smooth, efficient energy transfer or bonding processes in various technological applications.


The phonetic pronunciation of the keyword “Flux” is: /flʌks/

Key Takeaways

  1. Flux is an application architecture that enforces unidirectional data flow, making it easier to manage and debug complex applications.
  2. Flux consists of four main components: actions, the dispatcher, stores, and the views, which work together to handle data and create a more maintainable system.
  3. Flux is not a library or framework, but a design pattern that promotes better organization and improved performance in applications, often used with React for building user interfaces.


The technology term “flux” holds importance as it signifies the rate of flow, change, or movement of a certain quantity, such as energy, particles, or data, through a specified area or system over time.

In various technological fields, including computer science, electronics, electromagnetism, and thermodynamics, flux plays a crucial role in understanding and analyzing system behaviors and efficiencies.

For instance, in electronics, flux is used to facilitate the flow of solder and achieve reliable connections between components, while in computer science and data management, data flux highlights the importance of coping with rapidly changing data and resources.

Overall, flux offers vital insights for designing and optimizing systems, leading to advancements and innovations in technology.


Flux, in the context of technology, is a term widely associated with the architecture pattern used for designing client-side web applications. The fundamental purpose of Flux is to ensure a unidirectional data flow, making it easier to understand, manage, and debug web applications. It significantly improves the functioning of web applications, particularly those with complex data-handling requirements. Flux achieves this by streamlining data flow to eliminate potential challenges that might arise due to cascading effects when multiple components update each other simultaneously.

The architecture pattern breaks down the process into distinct actions, promoting a more organized and efficient structure. Flux primarily consists of four key components: Action, Dispatcher, Store, and View. Actions are responsible for triggering the necessary updates in the application, while the Dispatcher serves as a central hub that manages the distribution of these actions. The Store, on the other hand, retains the application’s data and state, ensuring consistent updates across connected components.

Lastly, the View is the UI component that visualizes the data being processed. By implementing Flux, developers can build more scalable, maintainable, and stable web applications. It intends to address the pitfalls of earlier patterns, like the Model-View-Controller (MVC) pattern, that encountered challenges as applications grew in complexity. Overall, Flux enhances not only the performance of web applications but also their usability and adaptability.

Examples of Flux

Electric Vehicles (EVs) and Energy Storage: One of the main applications of Flux technology is in the development of high-performance electric vehicles and energy storage systems. Flux power systems involve both magnetic and electric fields, which can be used to develop more efficient and lightweight batteries. A startup called “Flux Technologies” has been working on a patented magnetic battery technology, which provides higher capacity, faster charging, and longer life cycles compared to traditional Li-ion batteries.

Wireless Power Transfer: Flux is an essential concept in wireless power transfer, as it facilitates the transfer of power without the need for physical connections. One real-world example of this technology is WiTricity, a company that designs and develops wireless power transfer solutions using magnetic resonance technology. This technology enables electric vehicles to be charged without the need for cables by simply parking over a charging pad.

Magnetic Levitation Trains (Maglev Trains): Flux technology is a key component in the operation of magnetic levitation trains, which use magnetic fields to levitate and propel the train at high speeds. The Maglev trains have virtually no friction, enabling them to achieve speeds up to 375 mph (604 km/h), and providing faster, more efficient, and environmentally friendly transportation. The Shanghai Maglev Train in China is a prime example of Maglev transportation technology.

Frequently Asked Questions about Flux

What is Flux?

Flux is a programming architecture that is used mainly for managing the flow of data within web applications. It was developed by Facebook to work with React, complementing its component-driven approach.

What is the core concept of Flux?

The core concept of Flux is to maintain a unidirectional data flow within web applications. This means that data and actions always move in one direction, making it easier to comprehend and modify applications during development.

What are the main components of Flux?

Flux consists of four main components: Actions, Dispatcher, Stores, and Views (React components). These components work together to facilitate the unidirectional data flow that Flux is known for.

How does Flux differ from other architectures like MVC?

Unlike the traditional Model-View-Controller (MVC) architecture, Flux enforces unidirectional data flow. This reduces the complexity of managing state in an application and prevents issues related to circular data flow that can arise in MVC applications.

Is Flux only used with React?

While Flux was developed by Facebook to complement React, it can be used with other libraries or frameworks as well. Some developers have successfully integrated Flux with Angular and Backbone.js, among others.
