# iferr Higher-order functions for easier error handling. `if (err) return cb(err);` be gone! ## Install ```bash npm install iferr ``` ## Use ### JavaScript/ES6 example ```js var iferr = require('iferr'); function get_friends_count(id, cb) { User.load_user(id, iferr(cb, user => user.load_friends(iferr(cb, friends => cb(null, friends.length) )) )) } ``` ### JavaScript/ES5 example ```js var iferr = require('iferr'); function get_friends_count(id, cb) { User.load_user(id, iferr(cb, function(user) { user.load_friends(iferr(cb, function(friends) { cb(null, friends.length) })) })) } ``` ### CoffeeScript example ```coffee iferr = require 'iferr' get_friends_count = (id, cb) -> User.load_user id, iferr cb, (user) -> user.load_friends iferr cb, (friends) -> cb null, friends.length ``` (TODO: document tiferr, throwerr and printerr) ## License MIT
