Express • TodoMVC, adapted for fly.io

This is a fork of jaredhanson/todos-express-sqlite, with the following modifications:

• adds WebSocket support. Launch todo lists in multiple tabs/windows/browsers; changes made in one are reflected in all.
• replaced Sqlite3 with PostgreSQL for the database.
• adds Redis support for coordinating WebSocket updates.

With these changes multiple replicas of this application can be deployed, even in multiple regions.

Deployment

In an empty directory, run:

fly launch --from /~https://github.com/rubys/todomvc.git

If you visit this application, you will see a standard todo list.

To create additional machines in other regions, run:

fly scale count 3 --region dfw,waw,syd

Note: By default, all machines will be configured to automatically stop and start.
