angel_multiserver 1.0.0-dev+2

Support for running Angel applications across multiple servers.

multiserver

Support for running Angel applications across multiple servers.

The idea is that you have one master server running the load balancer, and the child applications call a session synchronizer.

Dedicated WebSocket support will come eventually.

See the examples;

Load Balancing

This package exposes a LoadBalancer class. The default implementation is a simple round-robin, but it can be extended for your own purposes.

Session Synchronization

This package also includes three SessionSynchronizer classes:

• MongoDB
• Memcached
• Redis

These are simply plugins that serialize and deserialize session data to external data stores. Try to call them as early as possible in your application, so that session data is loaded before any business logic.

import 'package:mongo_dart/mongo_dart.dart';

main() async {
    var app = new Angel();
    var db = new Db('<connection-string>');
    await db.open();
    await app.configure(
        new MongoSessionSynchronizer(db.collection('sessions')));
