super-proxy

superProxy is a function that returns a function/object that has every property as a recursive version of itself. This is useful if you want to fake that an object exists but you want to remove the behaviour.

Installation

In a browser

<script src="http://unpkg.com/[email protected]/umd/super-proxy.js"></script>

With npm

npm install super-proxy

Usage

const foo = superProxy()
foo.bar // this is okay
foo.bar() // also okay
new foo.bar().baz // all of this is okay

Use Case Example

Let's say you have loaded Segment with a script tag and in your application you have many calls to window.analytics.track that you would like to skip.

With super-proxy you can do:

window.analytics = superProxy()
window.analytics.identify(...) // this does nothing now
window.analytics.track(...) // same here
window.analytics.whatever(...) // there is no tracking!
