You can replicate the Flux architecture using plain React, building applications and reusable components that are easy to reason about, maintain, and extend.

Just get Flux’s architecture chart and replace:

  • action with event
  • dispatcher with a callback in your parent (controller) component that you pass down to every child component
  • stores with state
  • views are the same old React views


If you are into ReactJS you probably wondered whether or not you should use Flux.

In this post I’ll share with you a design pattern that implements a very similar Flux architecture, but using just plain React.

I have tested this “Flux without Flux” in many different settings, including reusable components, with great success and I’d love it if you gave it a try and let me know what you think.

To Flux or not to Flux?

This is a very common dilemma among engineers that use React — and rightfully so.

You want to keep your code better organized so that it is easier to reason about and allow the rest of your team to quickly understand how your application is structured.

On the other hand, you looked at the online Flux documentation, maybe tried to walk through some of the Flux examples, and started having second thoughts:

  • It looks more complicated than just using React
  • Will my team be able to pick it up quickly?
  • Which Flux flavor should I pick?

Sound familiar?

Well, don’t despair!

The “Flux without Flux” pattern that I’m about to share will give you many of the benefits of Flux architecture while using vanilla React.

Disclaimer: I have not used Flux extensively so I can’t speak about how this pattern compares with it or in which cases you might need to use the actual Flux architecture over the “Flux without Flux” patter that I am suggesting. Please use your own judgment. This might not be the perfect solution to all your problems.

A Quick Flux Recap

If you visited Facebook’s Flux documentation you probably came across this chart:

Flux data flow

The basic premise of the Flux architecture is:

  • An action is triggered which creates a payload and hands it to the dispatcher
  • The dispatcher delegates the payload to all the stores registered with it
  • The stores update themselves and emit a change event
  • The React views listen to the change events and update themselves based on the new data from the stores

The Flux without Flux Pattern

In the FWF pattern, the Flux architecture is adapted to use React elements:

Event => onAction => State => View

  • A user interacts with your application and triggers an event
  • The event handler creates a payload and hands it to the parent component’s onAction
  • The onAction calls the appropriate method that updates the state
  • React automatically updates all components passing new props to them

Not 100% sure how to piece this together?

In the parent component create a callback method (I like to call it onAction) and pass it down to all your child components via props.

When an event gets triggered, call the appropriate child component’s event handler. In it, create a payload object with an action and a value. Then, call the parent’s onAction, that is passed down via props, giving it the payload you created.

Finally, in the parent component use a switch that reads the payload.action and delegates it to the appropriate method that knows how to update the state with the payload.value.

React takes care of the rest automatically.

A Simple “Flux without Flux” Example

Here’s an example of the “Flux without Flux” pattern:

In this example I’ve created a simple application allows us to create and list comments.

Let’s walk through this example:

  • Clicking the submit button in NewComment uses this.props.onAction to dispatch an action with payload:

    payload = {
      action: "SUBMIT_NEW_COMMENT"
      comment: {
        comment: this.state.comment,
  • onAction grabs the payload, runs it through the switch and calls _onSubmitNewComment
  • _onSubmitNewComment updates the state of the parent component, CommentApp
  • CommentApp passes the new comments from its state down to CommentList via props
  • CommentList updates, rendering the new list of comments

Final Thoughts

I’ve started using the “Flux without Flux” pattern recently and so far it feels very nice and effortless. Things are where my team and I expect them to be and it’s quite easy to navigate around the codebase.

I also find it easy to reason about events and their consequences. Plus, I can just use the React I know and love!

That being said, this is a fairly new pattern and React is not that old either. So please take my suggestions with a grain of salt and if you decide to give this a try, I’d love to hear about your experience!
