Building Modules

If I have seen further than others, it is by standing on the shoulders of giants.

What is modular thinking?

Separating a program’s functions into
independent pieces,
each containing all the parts needed to execute a
single aspect
of the functionality

Why should i build a module?

Modular programming enforce logical boundaries between components and improve maintainability

Managing Code

Why should i build a module?

The same code can be used in many applications.

Code Reuse

Why should i build a module?

Teams can develop modules separately and do not require knowledge of all modules in the system.

SEPARATION OF CONCERNS

Why should i build a module?

Easily extend ANY application by just building on top of the modular architecture

EASIER EXTENDABILITY

USING A Public/private MODULE

FORGEBOX.IO

TYPES OF MODULES

INTERNAL MODULE Examples

EXTERNAL (THIRD PARTY)

MODULE Examples

API Versioning /API/v1

Validation & Security

Shared Utility

Mailing Services

Internationalization

ORM & Query Services

Logging & Debugging Service Integration

API Wrappers (s3,twilio,RabbitMQ,stripe,swagger, etc.)

How do i install a module into coldbox?

box install jsondiff

Using commandbox

Manual Install

Download Zip from Repo

Unzip

COPY/MOVE FOLDER INTO

/MODULES FOLDER

IN COLDBOX APP

 

HOW DO I USE A MODULE?

RTFM

Adam Cameron (TM)

 

(BUT FOR A MAJORITY...)

​FYI some modules don't need to be injected

(eg. cbsecurity)

HOW DO I change settings/

configuration

in A MODULE?

moduleSettings = {
    qb = {
        defaultGrammar = "MySQLGrammar@qb"
    }
};

I can't find a module that solves my problem!!! What should i do?

Step 1. Check to make sure you are searching for the right solution

If you have made it here its because you need to build it yourself!

Great where do we start

DONT REINVENT THE WHEEL....
CHANCES ARE YOUR NOT THE FIRST TO HAVE THIS PROBLEM

LOOK FOR INSPIRATION FROM PROJECTS IN OTHER LANGUAGES

interceptor LIBRARIES

Maintenance Mode

SSL Support Interceptor

Deploy

Multi Domain SES

Reserved Routes

WRAPPER LIBRARIES

STRIPE API

PINGDOM API (UPTIME MONITOR)

SPOTIFY API

TWITTER API

TWILIO API (SMS/CALL SERVICES)

ALGOLIA API

OF EXISTING JAVA LIBRARIES

variables available to the

module_config

appMapping
 
The appMapping setting of the current host application
binder The WireBox configuration binder object
cachebox A reference to CacheBox
controller A reference to the application's ColdBox Controller
log A pre-configured LogBox Logger object for this specific class object
logbox A Reference to LogBox
moduleMapping The moduleMapping setting of the current module. This is the path needed in order to instantiate CFCs in the module.
modulePath The absolute path to the current loading module
wirebox A Reference to WireBox

Module Helpers

Every module can declare an array of helper templates that contain methods that will be added as global application helpers.

 

This is a great way to collaborate global functions to the running MVC application.

 

This is done via the this.applicationHelper directive in your ModuleConfig.cfc.

This is an array of relative paths in the module that ColdBox will load as mixins.

this.applicationHelper = [
  "includes/helpers.cfm"
];

// Here is a sample of a helpers.cfm:

<cfscript>

function auth() {	
  return wirebox.getInstance( "AuthenticationService@cbauth" );
}

</cfscript>

What is wirebox?

  • Dependency Injection Framework for CFML
  • Creates, assembles, and stores your objects
  • Controls the lifetime of your objects (Scopes)
  • Easily define your object dependencies
  • Used in ANY CFML application
  • Removes creation boilerplate, duplicate code
<cfdump var=#( wirebox.getBinder().getMappings().keyArray() )#>

Helpful for debugging

ON DI COMPLETE()

Scopes

  • Scopes tell WireBox where and how long to store our objects
  • Common Scopes
    • NOSCOPE (default) - new instance each time requested
    • SINGLETON - single instance for injector lifetime
    • REQUEST - single instance for request lifetime
    • SESSION - single instance for session lifetime
    • APPLICATION - single instance for application lifetime
    • SERVER - single instance for server lifetime

javaloader

  • create( class ) - Create a loaded Java class
  • appendPath( dirPath, filter) - Appends a directory path of .jar's,.classes to the current loaded class loader.
  • getLoadedURLs() - Get all the loaded URLs
component accessors=true{

	// DI
	property name="javaLoader" inject="loader@cbjavaloader";
	property name="settings"   inject="box:modulesettings:bcrypt";

	/**
	 * Constructor
	 */
	BCrypt function init(){
		return this;
	}


    function onDIComplete(){
        variables.bcrypt = variables.javaLoader.create( "org.mindrot.jbcrypt.BCrypt" );
     }
}

Life-cycle Events

function onLoad(){
  // Register some tables in my database and activate some features
  controller.getWireBox().getInstance('MyModuleService').activate();
    log.info( 'Module #this.title# loaded correctly' );
}

function onUnLoad(){
  // Cleanup some stuff and logit
  controller.getWireBox().getInstance('MyModuleService').shutdown();

  // Log we unloaded
  log.info( 'My module unloaded successfully!' );
}

Lets see

some code....

Does some initial scaffolding for your app to name it and set up its module name
