Minify empty function

This is mostly a Facebook-specific transform that removes noop function calls. However, can be generalized to detect and remove noops

Example

In

function emptyFunction(){}
emptyFunction('how long','?');
foo(emptyFunction('how long', '?'));

Out

function emptyFunction(){}
foo(false);

Installation

npm install babel-plugin-minify-empty-function

Usage

.babelrc

{
  "plugins": ["minify-empty-function"]
}

Via CLI

babel --plugins minify-empty-function script.js

Via Node API

require("babel-core").transform("code", {
  plugins: ["minify-empty-function"]
});
