options

Node module to get/set configuration and runtime options

Set and get configuration options. Set defaults, use environment variables or override from an object. Options are key-value pairs.

Usage:

const Options = require('./src/options.js')
let opts = new Options
opts.setOpts(objWithOptions)          	// set key-value pair for each k-v pair in objWithOptions
opts.setFromEnv(arrayOfEnvVarKeys)    	// set k-v pairs using array of keys and their associated environment variables values
				       					// Environment variables come from the 'process.env' object									
opts.getOpt(optName [,optType])       	// get value for key optName as type optType
opts.getAll()                         	// get all k-v pairs

Examples:

let opts = new Options
let a = opts.getOpt("theKey","string","The default value")
let b = opts.getOpt("theKey")
