This is closed but i still like reflux for its simplicity

[koistya]

@ChaosD It seems like Reflux misses some important characteristics of the Flux architecture: Can you dispatch actions in a predefined order with Reflux? Make sure that all the actions are dispatched synchronously (the next action dispatching does not start before finishing dispatching of a previous one)? Can a single action creator / method dispatch more than one action at a time (a couple of different actions)?

[buxel]

Be warned, I most certainly cannot answer your questions in a satisfying way because I'am just getting started with react. I like the simplicity because it seems to streamline the whole process a bit more (maybe too much for you) and makes it easier for me to get started with. What i got so far is, that its possible to order your "dispatching", quoting the readme here:

waitFor is replaced in favor to handle serial and parallel data flows:

• Aggregate data stores (mentioned above) may listen to other stores in serial
• Joins for joining listeners in parallel

I could not find anything about action creators dispatching multiple actions but since actions dispatch themselves, i imagine you could simply call multiple actions to get what you need. I'am not quite sure if I got you right here but i cannot imagine a situation where this might be required. Could you elaborate?

These articles seem to address some of your concerns and helped me a lot understanding reflux:

• http://blog.krawaller.se/posts/react-js-architecture-flux-vs-reflux/ (basic info)
• http://spoike.ghost.io/deconstructing-reactjss-flux/ (probably your answers)

[buxel]

Have you reopened this issue for further discussion or are you already considering reflux? I'd love to hear your opinion about it because I'am also about to make this decision.

[buxel]

I just studied the flux docs again and it seems that you are right. if you want to stick to flux as close as possible, reflux might not be the best bet. Fluxxor is new to me, thanks for pointing me there. I will definitely check it out.

[buxel]

I played a bit with Fluxxor and it convinced me. It is really better if you do not want to be led astray from the Flux pattern. What do you think about McFly?

Maybe it is time to rename the issue... ;)

[buxel]

@f , in what way Delorean is different to the previously mentioned? How does it handle the concerns @koistya mentioned with reflux?

Btw, I really love how so many Back To The Future themed libs pop up so fast! :D

[buxel]

A nice summary can be found here: https://reactjsnews.com/the-state-of-flux/

[patrick-fls]

I personally settled for Fluxxor. I think it's the perfect blend between vanilla flux and reduced boilerplate and you can further reduce it with custom mixins. If the project ever dies, it would be easy to migrate. It's a non negligible advantage if you're in react for the long term.

[frankleng]

one more to consider... https://github.com/arqex/fluxify

[hipertracker]

I don't see compelling reason why to use Dispatcher. I prefer Reflux, it's simpler and cleaner.

[irium]

I'm personally using https://github.com/goatslacker/alt

[honkskillet]

FWIW, a bunch of the links to the npm packages (from the images) go to the wrong packages.

[mridgway]

If the goal is for the application to be isomorphic, you should look into our Fluxible library. We're using store instances instead of singletons to avoid concurrency issues that you'd see on the server when doing isomorphic.

[koistya]

@mridgway, but that adds complexity... Have you tried the other way around - keep using singletons, but make sure that each server-side rendering operation (HTTP request) uses a separate JavaScript execution environment?

[mridgway]

You have two options if you want to use a separate environment: use a separate node process for rendering each request or using node's vm module. Neither of these options will give you very good scalability.

We haven't found that it adds that much complexity at all. In fact, it makes it easier to test stores because you don't have to worry about side effects between tests. You can see an implementation of Fluxible in our flux-examples or our docs site.

[koistya]

@mridgway what about rendering React app directly with V8 without Node's overhead?

[goatslacker]

I came to post about this exact thing and found this discussion.

alt gives you lots of flexibility in terms of isomorphism, you can keep your stores as singletons without using vm or you can take the fluxible approach and create instances of flux and pass it around your react components using context.

The case for alt:

• Actually flux. It doesn't deviate from the flux architecture and uses flux's dispatcher.
• Isomorphic. Both creating instances or keeping stores as singletons.
• Terse, lessens the overhead (no constants, switch statements, no writing own dispatcher) but still has all the benefits of those (code grepability, able to listen to global dispatcher)
• Has some nice features (bootstrap / snapshots) which allow you to save the entire application state and then reload it later. This is great for debugging.

[cluelessjoe]

Well, there is also Flummox which aims to be idiomatic, modular, testable, isomorphic Flux & with no singletons required.

[aaron-goshine]

I came across this post and thought it was quite interesting, I have read the FLUX docs a while back and the possibilities are endless, however these flavours of flux just add a few tweaks to the Facebook flux minus a few of the core concept. (dispatching order, single point store optimisation, wait-for, and over all granular control) Moreover the Facebook flux is more tested, more used and Facebook have demonstrated that it is very scalable.

The npm charts that are at the top of this page, is not drawn on the same scale, so comparing them visually will be misleading read the values carefully

[goatslacker]

@aaronGoshine I encourage you to check out a lot of the flux libraries if you're interested in flux. Most of them use the flux dispatcher so contrary to what you're saying they add value on top of flux. A lot of these libraries are also used in production on high traffic websites like fluxible and alt.

[dandv]

What a wonderful example of the paradox of choice!

No wonder that it's easier to get started with Meteor + React, than with Flux + React.

[erkieh]

@goatslacker and others I found a old post at https://news.ycombinator.com/item?id=8989495 saying "Alt[1] has isomorphic support but there are some trade offs such as you're unable to use actions on the server."

Is this still the case? Are there other libraries which support actions on the server? Since i have yet to make a single react app, i don't know how relevant this feature is.

[goatslacker]

@erkieh depends on what you're going for and what your setup is like:

You can go a singleton-free approach a'la Fluxible and pass around your instance down through props or context (or even better use something like AltContainer) this will allow you to call actions on the server and load your data into your stores. You'll probably need to keep track of your actions so you know when to render, alt's actions return so this is a matter of just returning a promise from each action (you can also use ES7's await syntax)

In some cases you already have all the data available, say you're using rails or something, in which case all you need to do is load it into the right stores and then render. In that case you can go with singletons, just load your stores up using bootstrap and then flush them after you've created your markup.

I'll be posting a how-to isormorphic guide sooner or later.

[elliottmason]

@dandv The irony is that, for a newb like myself, Meteor becomes another option to research. Thanks for mentioning it, though (sincerely).

[dandv]

@lleolin: the difference is that you can pick up the basics of Meteor in one hour and that will give you a lot more out of the box (a web+mobile reactive app built on a realtime platform) vs. what you'd learn from one Flux implementation (just a server).

[Kobold]

@dandv Stop shilling for Meteor. It's cool tech, but this is a discussion of flux implementations.

[scottycoupa]

I dont mind knowing Meteor is an option.

[koistya]

There are some other alternatives as well, take a look here (RxJS) and here (Minimongo).

[sompylasar]

Have a look at this one: https://github.com/optimizely/nuclear-js

[vjpr]

Flummox is now deprecated in favour of Redux.

[coryhouse]

@koistya Can you please add these two to your list? (and thanks for the excellent compilation!)

https://github.com/optimizely/nuclear-js https://github.com/gaearon/redux

[hipertracker]

Flummox is replaced by Redux.

[luqin]

How about redux ?

[goatslacker]

Just in case no one has mentioned it, redux?

[ericdfields]

@hipertracker how does redux "replace" flummox, exactly? Seems like they have two very different approaches.

[hipertracker]

@ericdfields "Flummox 4.0 will likely be the last major release. Use Redux instead."

[ericdfields]

@hipertracker oh, right there in the readme.

i'm an animal.

[luandro]

Redux seems to be the clear winner

[Dindaleon]

Can someone please tell me what this is: https://github.com/elierotenberg/react-nexus and https://github.com/elierotenberg/nexus-flux Does it have anything to do with flux? What can I use it for? I am leaning towards using redux.

[iMoses]

Can I get some pros and cons from someone who used redux for a large scale / complicated project?

[AlexGalays]

Small and straight-to-the-point implementation: https://github.com/AlexGalays/fluxx

[AdamBrodzinski]

What a wonderful example of the paradox of choice! No wonder that it's easier to get started with Meteor + React, than with Flux + React.

I think it's worth mentioning that _flux doesn't replace Meteor_. In fact Meteor doesn't have any built in architecture to keep yourself from getting buried in a game of 'whack a mole' when changing large codebases. I did write a spec for something based on flux to solve this (using Blaze) but that's off topic.

However i've used Meteor + flux + React to have a pretty nice workflow with @goatslacker 's Alt. This gives you Relay type benefits while still using flux. In this context, Alt's snapshots are handy because you can snap the state before a hot code reload and bootstrap on re-load. It also makes it easy to track mongo cursors and update the store on change. Alt seems to be one of the best choices so far with Meteor. I've used it in a large Meteor prod app and it's working great.

If interested I have a leaderboard repo with Meteor + Alt/Reflux + React: https://github.com/AdamBrodzinski/meteor-flux-leaderboard

[jaraquistain]

Looks like alt will directly replace MartyJS but the developer suggests Redux as superior:

I understand Redux is the crème de la crème when it comes to Flux implementations (as of this hot minute), but I personally find the concept of immutables and reducers too much to grok for a starter kit. To quote James Long on Immutables:

[Y]ou never know if you are working with a JavaScript object or an Immutable one. This makes reasoning about functions harder.

[bartekus]

Any ideas as to the best way to wrap whole application state with Provider as per Redux requirement? I tried to inject Provider into src/app.js into the ReactDOM.render but I'm getting Unhandled promise rejection ReferenceError: React is not defined tho webpack is bundling without a hitch and not reporting any error.

I've circled the addition so everything is as per current version save for these imports and the constant that were also added for obvious reasons: import { Provider } from 'react-redux'; import configureStore from './store/configureStore'; const store = configureStore();

[sompylasar]

@Bartekus

ReferenceError: React is not defined

That's because any JSX expression (<Provider ...>...</Provider> in your case) is transformed to React.createElement() under the hood.

I've circled the addition

That's what you get after JSX:

ReactDOM.render(
  React.createElement(
    /*string/ReactClass type*/ Provider,
    /*[object props]*/ { store: store },
    /*[children ...]*/ {
      component: component,
      appContainer: appContainer,
      () => {
        // ...
      }
    }
  )
)

Is this what you expected to get?

[bartekus]

@sompylasar Oh damn, I'm so thick, thank you for pointing the problem out and for the possible solution! I guess in case of react-starter-kit direct, conversion to redux aint going to be as smooth as I was hoping it to be lol but erikras' example is the best yet so let's see if I can bend react-starter-kit to redux will...

On a side note I'm kinda surprised nobody has converted this kit to redux yet, considering it's part of WebStorm and it now being used in real, high-end development.
