Sub Module Configuration

Are you the author of a NodeJS NPM module that accepts initialization parameters?

If so, and you're following a pattern like this for your module configuration:

varinitParams={param1: "value1",param2: 22}varMyModule=require('my-module');varmyModule=newMyModule(initParams);

Or this:

MyModule.setDefaults(initParams)

Then read on.

By following a common pattern, you give developers using your module:

Without breaking existing usage of your module, and without requiring node-config in their own app (unless they want).

Here's how it works:

Load node-config at the top of your module like normal, and specify the SUPPRESS_NO_CONFIG_WARNINGenvironment variable so applications don't get No config files warnings if they aren't using node-config.

process.env.SUPPRESS_NO_CONFIG_WARNING='y';varconfig=require('config');

Then do something like this where your configurations are passed in by the app:

functionmyModuleConstructor(configs){letmyDefaultConfigs={param1: "value1",param2: 22};// Orconst{ Load }=require("config/lib/util");constloader=newLoad({configDir: Path.join(__dirname,'./config')});myDefaultConfigs=loader.scan();// Mixin configs that have been passed in, and make those my defaultsconfig.util.setModuleDefaults('MyModule',myDefaultConfigs);}

Then use the config object as usual to access configurations within your module:

console.log('My module config param1: '+config.get('MyModule.param1'));

This pattern gives apps using your module the choice of using node-config mechanisms for configuration, or using your existing methods (as shown at the top of this page).

For example, they can put your module configurations next to their other configurations and extend configs based on deployment type:

default.json:
{
...
"MyModule": {
"param1": "Some value"
},
...
}

This is an easy way to add new configuration functionality to your NPM module, while staying compatible with existing usage.

It unifies your module configuration with apps choosing to use node-config, and stays out of the way for apps using other configuration systems.
