##Installation

###Installation via NPM

To install GraceNode you can either add it to your package.json like so,

{
    "dependencies": {
        "GraceNode": "git+https://github.com/voltrue2/GraceNode.git#master"
    }
}

or NPM install directly via npm install git+https://github.com/voltrue2/GraceNode.git#master.

###Creating configuration files

In your root directory create a directory that is called 'configs'. Although you can name it whatever you want, for this instruction we have named our directory configs.

$ mkdir configs/
$ touch configs/conf.json

Refer to example-config.json for an example configuration file.

##Bootstrapping GraceNode

GraceNode needs to be set up for it to run correctly. In your application add:

var gracenode = require('GraceNode');
//Set the configuration path.
gracenode.setConfigPath('configs/');
//Add configuration files that need to be loaded.
gracenode.setConfigFiles(['conf.json']);

// decide what module(s) of GraceNode to use in your application.
gracenode.use('server');
gracenode.use('view');
gracenode.use('mysql');

// now start the set up process
gracenode.setup(function (error) {
    if (error) {
        throw new Error('GraceNode failed to set up: ' + error);
    }
    // GraceNode is ready to go

});

#Gracenode ##Methods

###.setConfigPath(configDirectoryPath [string]) Tells GraceNode where to find the configuraitons files.

gracenode.setConfigPath('configs/');

###.setConfigFiles(configFileList [array]) Give GraceNode the list of configuration files to be used. The files must be in the directory given to setConfigFiles.

gracenode.setConfigFiles(['conf.json']);

###.use(moduleName [string], params [object*]) Tells GraceNode what modules to load when calling the setup functions.

gracenode.use('mysql');
gracenode.use('myModule');

###.setup(callback [function]) Start the setting up of GraceNode modules.

gracenode.setup(function(error) {
    if (error) return console.error('Could not load gracenode:', error);
});

###.exit(errorMessage [string*]) Exits GraceNode and attempts to gracefully shutdown the process. You can give it an error message in case you want to stop the process due to an error.

gracenode.exit('financialCrisis');

##Events Gracenode has the capabilities to emit events, you can catch these events using:

gracenode.on('event.name', yourEventHandler);

###setup.config Emitted when the config module has been set up. ###setup.log Emitted when the log module has been setup. ###setup.complete Emitted when the setup has been completed. ###setup.moduleName Emitted when a specific module has been setup. ###uncaughtException Emitted when GraceNode caught an uncaught exception. ###exit Emitted when GraceNode exits. ###shutdown Emitted when GraceNode detects SIGINT. This is before exit is emitted.
