Basic Usage

The example below will require a file called hello.js and will invoke the world method into this file, passing to the the object the parameters {name: 'john'} and a callback.

'use strict';

const Controller = require('controller-handler'),
      controller = new Controller(__dirname + '/src/commands');

const message = {
    command: 'hello',
    action : 'world',
    params : {name: 'john'},
};

controller.handle(message, function(error, data)
{
    console.log(error); // In case of error
    console.log(data);  // In case of success
});

Message Validation

'use strict';

const Controller = require('controller-handler'),
      controller = new Controller(__dirname + '/src/commands');

const message = {
    command: 'hello',
    action : 'world',
    params : {name: 'john'},
};

const validation = controller.validate(message);

The validation object returned by validate() will looks like this:

{
    command: true, // "command" param is provided and file "./src/commands/hello.js" exists
    action : true, // "action" param is provided and method "world" exists
    params : true, // "params" param is provided and it is a valid object
}

Simple Message Validation

'use strict';

const Controller = require('controller-handler'),
      controller = new Controller(__dirname + '/src/commands');

const message = {
    command: 'hello',
    action : 'world',
    params : {name: 'john'},
};

const valid = controller.isValid(message); // TRUE
