remove-function-loader

The Problem

We can run ifdef as a webpack loader, but it requires us to write additional code to parse. What if we have debugging, or development functions/methods being called that we simply want removed in production? Or what if we have method calls we want to omit when A/B testing new features?

The Solution

remove-function-loader reads your specficied files and removes function called (not definitions) from the file during a webpack build. It retains the function in the source code but the output from webpack has absolutely no calls to the specified functions.

Install

npm install --save-dev remove-function-loader

Setup

note: use Babel before running this loader

module: {
   rules: [
   {
     test: /\.js?$/, // Check for all js fi
     exclude: /(node_modules|bower_components)
     use: {
       loader: path.resolve('./src/loader.js'),
       options: {
         functions: ['hello', 'ttt.hello'],
         removeDefinitions: false
       }
     }
   }, 
   {
     test: /\.js?$/, // Check for all js files
     exclude: /(node_modules|bower_components)/,
     use: [{
       loader: 'babel-loader',
       options: {
       presets: ['env']
      }
     }]
   }]
  }
},

To Do:

• Add support for removing function definitions
• Add more examples
