Maintain a synchronized data store between connected Node.js applications
npm install pnode-store---
> A peer-to-peer data store using dnode
* Fast
* All data is transfered over dnode
* Achieve about 1.2k replications/sec
* Replicate mutating operations
* Connections automatically recover
* Status pings and reconnects are controlled by upnode
* Create smart data buckets for control over replication
* Prefills buckets with peer data
* Implement your own bucket types
* Default bucket type is a plain object (pure memory)
* lru-cache bucket type is operational so you may set size and TTL.
* LevelDB bucket type in progress...
* Express session store built-in
npm install peer-store
Server A at 10.0.2.1:
`` javascript
var PeerStore = require("peer-store");
var store = new PeerStore({
peers: ['10.0.2.2'];
});
store.set('foo',42);
`
Server B at 10.0.2.2:
` javascript
var PeerStore = require("peer-store");
var store = new PeerStore({
peers: ['10.0.2.1'];
});
store.set('bar',7);
`
On both Sever A and B:
` javascript`
store.getAll(function(data) {
console.log(data); // { foo: 42, bar: 7 }
});
In addition to the above, do:
` javascript`
app.use(express.session({
store: store.sessionStore(),
secret: 'secr3t'
}));
Now all your sessions are magically shared
Todo...
dnode depends on node-gyp, so in order to npm install on Windows, you'll need to follow the node-gyp Installation guide. Unix and Mac requires python and make` so it should just work.
Quick windows links:
* Download Python 2.7.5
* Download Visual C++ Express 2010
* Download Windows 7 SDK (Windows 7 Only)
Most of the work is being done by substack's dnode
