cept

cept

Intercept method calls.

Installation

npm:

npm install cept

Usage

var cept = require('cept')

// Intercept:
var stop = cept(console, 'log', noop)

// From now on `console.log` is ignored:
console.log('foo bar baz')

// No longer ignored!
stop()

function noop() {}

API

stop = intercept(context, key, callback)

Intercept all calls to context[key] (e.g., console.log). From now on, when the original method would be invoked, callback is used instead. Invoking stop reverts everything back to normal.

Parameters

• context (Object) — Context object
• key (string) — Property where the original function lives
• callback (Function) - Interceptor

Returns

Function — Used to revert back to the previous function.
