Knockout Live Plugin

Installation:

Clone the repository

npm install
node server.js

Visit /index.html to see the example chat application.

Files:

• js/knockout.live.plugin.js on the client
• js/main.js has the example for the chat application
• server.js running on node server

Dependencies:

• Knockout 3.4.0
• Socket.io v1.3.7 client/server
• Node.js and socket.io on the server side
• index.html should be requested from a web server e.g. apache, nginx

Notes

• The chat example runs on port 4000, change port variable in js/main.js and server.js if required
• Check the terminal for logs (message sent & disconnected client)

What do you need for your application to go "live"?:

• Set .live() on all ko.observable() and ko.observableArray() you want to synchronize remotely(see the chat example)
• Run ko.utils.socketConnect(address,port) before ko.applyBindings()

Options for live():

• id: "my_id" sets a custom ID for sync purposes. This is useful if you are syncing between different apps.
• readonly: true blocks all direct changes to the live observable. It will update only by socket messages from the server.

TODO:

• Adapter interface for sync options besides socket.io
