defaults

A simple one level options merge utility

install

npm install defaults

use


var defaults = require('defaults'); var handle = function(options, fn) { options = defaults(options, { timeout: 100 }); setTimeout(function() { fn(options); }, options.timeout); } handle({ timeout: 1000 }, function() { // we're here 1000 ms later }); handle({ timeout: 10000 }, function() { // we're here 10s later });

summary

this module exports a function that takes 2 arguments: options and defaults. When called, it overrides all of undefined properties in options with the clones of properties defined in defaults

Sidecases: if called with a falsy options value, options will be initialized to a new object before being merged onto.
