We need a Node.js service that does the following. Please read the description below and reply describing your experience with Node.js and any questions you may have about this description. 1. The service should accept TCP SSL connections from end users/clients who will connect and then send their username/password. 2. On receiving username and password, the service will connect to an XMPP server (like Google Talk) using the username/password. This should use the node-xmpp module: [login to view URL] 3. If the authentication with the XMPP server succeeds, send a success msg back to the client, or else send a failure message. 4. After the connection succeeds, forward any XML messages/stanzas from the client to the XMPP server and anything from the XMPP server to the client. 5. When the client breaks the SSL socket, keep the connection with the XMPP server open and cache any messages from the XMPP server in a queue. 6. When the client connects again in the future with the same username and password, if there is an existing open connection to the XMPP server, just send a success to the client. And send to the client any cached messages from #5 above. 7. If a successfully connected client sends a 'disconnect' message, then close the connection with the XMPP server. 8. The node.js service should accomodate any number of clients and should keep track of matching clients with their XMPP connections. Deliverables should include: - The node.js service - A command-line client program in any language that acts as a client to the service You should use Google Talk as the XMPP server. Please see attachment with a diagram depicting the message exchange.

Greetings. My name is Jeremy Trammell and I represent a group of developers and designers in Portland, Oregon. We have extensive experience with Javascript as well as with the excellent node.js package. If you examine our recent reviews on this website you will see that we have completed and been re-hired quite recently for some node.js development work. I have two questions regarding your project. First: What kind of scale are you planning to support? If this is to be used with a very light load, then we can cache the XMPP messages in memory which is very simple. If, on the other hand, you intend to use this with many users and many cached messages, then you will need a database to store the cached messages in. Second: How sophisticated do you want the command line client to be? I assume it's just a tool that you will use to test out the server before accepting delivery, not something you intend for production use, yes?
