axon-rpc

RPC client / server for axon.

arpc(1)

The arpc(1) executable allows you to expose entire node modules with a single command, or inspect methods exposed by a given node.

Usage: arpc [options] <module>

Options:

  -h, --help            output usage information
  -V, --version         output the version number
  -a, --addr <addr>     bind to the given <addr>
  -m, --methods <addr>  inspect methods exposed by <addr>

Server

var rpc = require('axon-rpc')
  , axon = require('axon')
  , rep = axon.socket('rep');

var server = new rpc.Server(rep);
rep.bind(4000);

Server#expose(name, fn)

Expose a single method name mapped to fn callback.

server.expose('add', function(a, b, fn){
  fn(null, a + b);
});

Server#expose(object)

Expose several methods:

server.expose({
  add: function(){ ... },
  sub: function(){ ... }
});

This may also be used to expose an entire node module with exports:

server.expose(require('./api'));

Client

var rpc = require('axon-rpc')
  , axon = require('axon')
  , req = axon.socket('req');

var client = new rpc.Client(req);
req.connect(4000);

Client#call(name, ..., fn)

Invoke method name with some arguments and invoke fn(err, ...):

client.call('add', 1, 2, function(err, n){
  console.log(n);
  // => 3
})

Client#methods(fn)

Request available methods:

client.methods(function(err, methods){
  console.log(methods);
})

Responds with objects such as:

{
  add: {
    name: 'add',
    params: ['a', 'b', 'fn']
  }
}
