Injection DSL

Everything inside CommandBox is built via Wirebox. This means your models, commands, and interceptors can all take advantage of Wirebox's dependency injection. All you need to do is add a property to the top of your CFC that tells WireBox what to inject.

Core Models

There are a number of automatically-mapped objects inside WireBox. Here are some examples:

property name='shell'           inject='commandbox';
property name='tempDir'         inject='tempDir@constants';
property name='formatterUtil'   inject='formatter';
property name='ModuleService'   inject='ModuleService';
property name='ConfigService'   inject='ConfigService';

Custom Models

Any CFCs in the models folder of any module will automatically be mapped in WireBox with the pattern modelname@modulename. Therefore, if you create a module called "SuperDuper" that has a CFC called models/AmazingService.cfc, you could inject it in your module's custom command like so:

property name='AmazingService' inject='AmazingService@SuperDuper';

Module Config and Settings

If a module's service or command wants to access configuration data or module settings, they can be injected using these injection DSLs.

property name='allModuleConfigs'    inject='commandbox:moduleConfig';
property name='moduleConfig'        inject='commandbox:moduleConfig:moduleName';
property name='moduleSettings'      inject='commandbox:moduleSettings:moduleName';
property name='mySetting'           inject='commandbox:moduleSettings:moduleName:mySetting';
property name='myDeepSetting'       inject='commandbox:moduleSettings:moduleName:mySetting';

CommandBox Config

You can also inject Commandbox config settings into your CFCs. Only inject a specific config setting if you expect it to exist. If you need to check for its existence (and provide a default), then inject the entire settings struct. You can also inject nested keys of a complex config setting directly like the last line shows.

property name='allConfigSettings'   inject='commandbox:ConfigSettings';
property name='myConfigSetting'     inject='commandbox:ConfigSettings:myConfigSetting';
property name='myDeepConfigSetting' inject='commandbox:ConfigSettings:myConfigSetting.nested.keys.here';
