Web Note Pad is a Web-based notepad script. It features a two paned interface that allows you to manage your documents, create new files, search text content, or select a file to load into the editor. Previous versions of documents are kept, and 30 days of history can be examined using the "Older" or "Newer" navigation buttons on the toolbar.
msg-rpc provides bidirectional RPC support over a simple message interface such as WebSocket. Tere are WebSocket examples based on socket.io and sockjs. It just has a simple sendMessage/onMessage interface, with no other dependencies. It supports not only normal RPC, but also RPC Service, which makes RPC pushable (i.e. the server can also send a request to the client and expect some kind of response).
