Getting started with Meshnet

This document is for people who want to help but have no technical knowledge. It assumes you won't be getting involved in squabbles over which relay technology to use, etc.

Step 1: Set up CJDNS

One of the few things widely agreed upon at the time of this writing is the use of CJDNS. Currently Windows is not supported, but if you have Linux or can run Linux in a virtual machine, you can follow the step-by-step instructions lower on that page to install and start up an instance of CJDNS on your system. If you're using Ubuntu 11.10 (latest version), you can follow these simplified instructions.

One thing you should know is cjdns currently isn't a wireless meshnet. A physical meshnet consisting of nodes geographically close to each other is a long way off. Instead, cjdns offers a "mixnet"-like system. cjdns is routable over the current Internet, so this means right now its like a giant VPN (virtu

// set-up a connection between the client and the server
var socket = io.connect();

// let's assume that the client page, once rendered, knows what room it wants to join
var room = "abc123";

socket.on('connect', function() {
   // Connected, let's sign-up for to receive messages for this room
   socket.emit('room', room);
});

Namespacing

The concept of namespacing keys will probably be familiar if you’re used to using a key/value store of some kind. By separating keys by prefixes we create discrete buckets, much like a table in a traditional relational database is used to separate different kinds of data.

It may be tempting to create separate LevelDB stores for different buckets of data but you can take better advantage of LevelDB’s caching mechanisms if you can keep the data organised in a single store.

Because LevelDB is sorted, choosing a namespace separator character can have an impact on the order of your entries. A commonly chosen namespace character often used in NoSQL databases is ':'. However, this character lands in the middle of the list of printable ASCII characters (character code 58), so your entries may not end up being sorted in a useful order.

Imagine you’re implementing a web server session store with LevelDB and you’re prefixing keys with usernames. You may have entries that look like this:

  /* a helper to execute an IF statement with any expression
    USAGE:
   -- Yes you NEED to properly escape the string literals, or just alternate single and double quotes 
   -- to access any global function or property you should use window.functionName() instead of just functionName()
   -- this example assumes you passed this context to your handlebars template( {name: 'Sam', age: '20' } ), notice age is a string, just for so I can demo parseInt later
   <p>
     {{#xif " name == 'Sam' && age === '12' " }}
       BOOM
