Flux Example with React & Meteor

Get the benifits of Relay without the wait or complexity

• Automatic optimistic UI updates (latency compensation)
• Real time database updates (like Uber's realtime driver location)
• Mini-Mongo client cache (easy clientside querying)
• Query based data subscriptions instead of REST (also API REST supported)
• Data operations in flux are written synchronously because of the optimistic UI

Plus

• Hot code reload
• Universal JS shared on client and server (isomorphic)
• Clean server-side code with fibers (soon with promise ES7 async/await)
• Easy microservice implementations via DDP
• Modular, swap out any default Meteor components you wish

Different Flux examples

• Alt: master branch
• Redux: redux branch
• Reflux: reflux-branch branch

***Make sure to open the console to see the lifecycle***

Full Readme coming soon! (See this readme for an explanation of the Meteor parts)

Usage

• cd meteor-flux-leaderboard
• meteor
• Open your browser to localhost:3000
• Checkout action/store logs in console after clicking about

### Todo

• [X] Basic functinality
• [ ] Handle hot code reload (snapshot and restore on reload)
• [ ] Serverside rendering branch (started, shared files but no SSR)
• [ ] Immutible stores for rendering performance
• [ ] React Router using actions

Key pieces are in CollectionActions/Store, Tracker watches for changes on the Minimongo clientside cache and emits a change event when data changes. This retains all the optimistic UI and realtime data capabilities that Meteor offers.

 Tracker.autorun(computation => {
    var docs = Players.find({}).fetch();
    
    if (computation.firstRun) return; // ignore first empty run
    
    this.CollectionActions.playersChanged(docs);
  });

This is simplified by using a helper package, though I think it's important to know how it works.

trackCollection(Players, CollectionActions.playersChanged);

Alt perks

Alt lets you take snapshots of your apps state and can undo/redo state as needed. You can use this to capture your app state on an error then send log it for debugging remotely.

A chrome extension is availible to help with local debugging:
