wrappers v0.2.3

Wrappers

Wrappers is a small library exporting basic wrapper functions for functions.

Usage

Attach it to the short variable of choice:

var w = require('wrappers');

then get some cheap extra funcitonality out of your functions with standard wrappers:

var safeInit = w.once(init); // invokes wrapped init function at most once
var tracedFn = w.trace(buggyFn); // logs input and output when called
var rateLimited = w.throttle(cpuHeavyFn, 200); // triggers at most every 200ms
var burstTrigger = w.repeat(w.repeat(fire, 5, 50), 3, 1000); // bursts of 5 every second 3 times

Read the API.

This module used to be included in functional utility library interlude, but is now an extra.

$ npm install wrappers
