After many many months of development, testing and waiting, we are finally able to release a major major update to our localization and internationalization library for ColdBox: cbi18n version 2.x. This release is a huuuge advancement for building localized applications and websites and partly thanks to Mr Wil de Bruin ( This release introduces the ability to use json resource bundles, multiple bundles per module, cbStorages for tracking locales, property inheritance and so much more! There are a few compatiblity issues, so make sure you read them to upgrade to version 2.x if not you can easily update using CommandBox:

install cbi18n
update cbi18n

What About cbValidation?

cbValidation 2.x does have a dependency on cbi18n version 1.x and that will remain coupled to the 1.x series. However, cbValidation 3.x is now under development and it will be bumped to support cbi18n 2.x.

Whats New With 2.0.0

Compatibility Updates

CFML Engines

Compatibility with Adobe ColdFusion 11 and Lucee 4.5 have been dropped.

Module Configuration Settings

You will need to move the i18n configuration structure in your config/ColdBox.cfc to the moduleSettings struct and rename it to cbi18n to standardize it to module settings.

moduleSettings = {

		cbi18n = {
			// The default resource to load and aliased as `default`
			"defaultResourceBundle" : "includes/i18n/main",
			// The locale to use when none defined
			"defaultLocale"         : "en_US",
			// The default storage for the locale
			"localeStorage"         : "cookieStorage@cbstorages",
			// What to emit to via the resource methods if a translation is not found
			"unknownTranslation"    : "**NOT FOUND**",
			// If true, we will log to LogBox the missing translations
			"logUnknownTranslation" : true,
			// A-la-carte resources to load by name
			"resourceBundles"       : {},
			// You can override the ResourceService with your own, just add the WireBox ID
			"customResourceService" : ""

ColdBox Module Settings

Every ColdBox module has the i18n capabilities available to them as well. They can use it to register their own resource bundles. The previous version allowed for a setting called i18n this is now called cbi18n to comply with the same global naming convention. Just update your key root in your Moduleconfig.cfc

cbi18n = {
		defaultLocale = "es_SV",
		resourceBundles = {
			"module@test1" = "#moduleMapping#/includes/module"

Locale Storage Options

  • localeStorage will use a cbstorages compatible service now. This means you have to specify the WireBox ID now, e.g CookieStorage@cbstorages , SessionStorage@cbstorages etc

Major updates

JSON Resources

cbi18n v1 already had java resource bundles. v2 added support for JSON resource bundles. Both flat and nested JSON bundles are supported.


    "sub.IntroMessage": "Normal JSON"
    "sub.IntroMessage": "JSON Normal"


    "sub": {
        "IntroMessage": "Nested JSON"
    "sub": {
        "IntroMessage": "JSON Incrustado"

Locale Storage

The locale storage has now moved to leveraging a cbStorages compliant driver. This way you can leverage any of the cbStorages drivers or anything custom you would like.

  • applicationStorage@cbstorages
  • cacheStorage@cbstorages
  • clientStorage@cbstorages
  • cookieStorage@cbstorages (default)
  • requestStorage@cbstorages
  • sessionStorage@cbstorages

Property Inheritance

In this version we introduced the concept of property inheritance. It means that key-values pairs included in less specific files are inherited by those which are higher in the inheritance tree. For example: Let's assume you are using a en_US locale. if you have key-values in a generic file, you can override them in a and an even more specific file. This opens up the possibility to define a generic language resource and define country specific translations in a more specific resource file.

The order of lookup is:

  • myBundle_en_US_somevariant.(properties|json)
  • myBundle_en_US.(properties|json)
  • myBundle_en.(properties|json)
  • myBundle.(properties|json)

New Mixin Helpers

You get some brand new helpers in this release:

 * Get i18n Model
function i18n()

 * Get the resource service model
function resourceService()

Unknown Translation Interception

The event onUnknownTranslation is emitted via an interception when a translation is not found. You will receive the following interception data packet:

    resource 	= ..., 
    locale 		= ... , 
    bundle  	= ...
