An extended Flux implementation to build isomorphic javascript React app.

Minimal context APIs

To understand Flux, you only need to learn these APIs: this.executeAction(), this.getStore(), this.dispatch() !

• this.executeAction() or this.getStore(name) in components.
• this.dispatch() or this.executeAction() or this.getStore(name) in actions.
• this.emitChange() or this._get() or this._set() in stores.

---

• [CORE] Super lightweight, less than 250 lines of code.
• [CORE] Context based flux system.
• [CORE] React Server side rendering + client mount.
• [CORE] HTML as top level react component, no need container.
• [EXTRA] express middleware to serve the fluxex application.
• [EXTRA] full integrated gulp task for development.
• [EXTRA] pjax support.
• [EXTRA] rpc and api call support.

See the FluxEx Magic

• Check example projects you can see how fluxex do server side rendering + context deliver + Full HTML react rendering!
• No more index.html. Start with npm:express and your Html.jsx!
• No more AJAX, all http request by npm:request!

Start from Scratch

Quick Start

Prepare your project

npm init
npm install fluxex

Use the Starter template

node_modules/.bin/fluxex_starter

Start the Server

node_modules/.bin/gulp develop

• Connect to http://localhost:3001/search?q=pizza
• You can start your development now, gulp handled everything (jshint, browserify, nodemon, restart, browser-sync).
• Put your actions, stores and components into correspond directories.
• Edit components/Html.jsx to include your React components.
• Edit actions/routing.js to add routing.
• Edit fluxexapp.js to add your store.

Difference with Flux

FluxEx is context based flux implemention. Server side react rendering can be done easy when the flux is scoped under a request based context. Store and dispatcher are singletons in Facebook flux, but in fluxex they are not.

---

**Fluxex** * Fluxex is an instance, it is constructed by provided context. * Fluxex can be serialized by `.toString()` and reconstructed by the serialized string. All server side store status can be transfered to client side by this way. * use the static `.createApp()` to create a Fluxex application.

var myApp = require('fluxex').createApp({
    product: require('./stores/product')
}, process.cwd() + '/components/Html.jsx');

---

**Action** * An action creator should return a promise. * An action creator function can be executed by `.executeAction()`. * When the action be `.executeAction()`, the Fluxex instance can be referenced by `this`. * `.executeAction()` will return a promise, so you can manage asynchronous actions in promise way.

// inside a component, requires Fluxex.mixin
...
onStoreChange: function () {
    return this.getStore('myStore').getSomething();
},
handleClick: function () {
    this.executeAction(myAction);
}

---

**Dispatcher** * the Fluxex instance itself is a dispatcher with `.dispatch()` method. * the dispatched `FOOBAR` action will trigger all `handle_FOOBAR` method of all stores. When there is no `handle_FOOBAR` method in any store, an error will be throw.

// myAction
var myAction = function (payload) {
    ... do your tasks ....
    return this.dispatch('UPDATE_SOMETHING', ....); // this returns a promise
}

---

**Store** * Store is an instance, it is constructed by serialized status. * Store is created by a Fluxex. * Use `.getStore(name)` to get the store by name. * You can `._get()` and `._set()` by property name. Ex: `this._set('data', 123)` * Everything you `._set()` can be serialized by `.toString()` and be tracked by your Fluxex application. * You can use `waitFor` property to refine dispatch depdency for specific action.

var myStore = {
    // the dispatch will happened after these stores be dispatched
    waitFor: {
        UPDATE_SOMETHING: ['oneStore', 'anotherStore']
    },

    // handle this.dispatch('UPDATE_SOMETHING', ....)
    handle_UPDATE_SOMETHING: function (payload) {
        this._set('data', payload); // There are ._get() and ._set() in all stores
        this.emitChange();
    }
}

Notes for IE8 support

• NOTE React v15+ stop supporting IE8
• You should add require('fluxex/extra/polyfill-ie8'); in your fluxexapp.js to polyfill EventListener methods and XMLHttpRequest consts for IE8.
• catch is reserved keyword in IE8, you need to replace somePromise.catch(...) with somePromise['catch'](...)
• for (... in ...) will loop beyond properties in IE8, you need to replace for (I in myArray) with myArray.forEach(function (V, I) { ...}

IE8 Unsupported features

• window.history.pushState
• set innerHTML of script or title node
• compare prototype.constructor with another function
• console and console.log when developer tool not opened
