micro-node-launcher

This is the heart of micronode. This module can start any node-module as a micro-service with an AMQP JSON-RPC 2.0 communication layer.

Usage

nodejs

// my_module.js

module.exports = {
    
    foo: function(cb){...}
           
    value: 'value',
    
    deep: {
    
        bar: function(cb){...}
    
    }
}

// app.js

var launch = require('micro-node-launcher');

launch('./my_module.js', 'rpc_queue', '127.0.0.1'); // listening on 127.0.0.1 for rpc calls

This will launch an AMPQ server listening on 127.0.0.1 for JSON-RPC 2.0 messages coming to the rpc_queue queue. From the shape of the module, the server can also proxy methods deeply in the object. That means that a deep methods like deep.bar is accesible with an RPC request like this one:

{
   
  jsonrpc: '2.0',
  method: 'deep.bar',
  id: SOMEUNIQUEID
}

The server add an additional internal method rpc.definition that contains information about the methods and the static values of module that it exposes.

We recommand that you use our client micro-node-client to communicate with this server.

cli

You could also use our CLI to start the server after installing the micro-node-launcher locally or globally like this:

micro my_module.js rpc_queue 127.0.0.1

Requirement

• NodeJS
