remove-debug-loader

remove debug from your code, by

• remove require and import debug
• remove method name - debug's definition and invocation (name debug is default and can be config in loader options)
• remove custom modules(when you patched debug library)

Installation

$ yarn add remove-debug-loader --dev

or

$ npm i --save-dev remove-debug-loader

How to use

config webpack.config.js with:

...
module: {
  rules: [{
    test: /\.js$/,
    use: [{
      loader: 'remove-debug-loader'
    }]
  }]
}
...

this would remove these patterns

requiring debug:

const debug = require('debug')

also support import syntax:

import debug from 'debug'

and debug methods

debug('some log to log', 'stuff')

since debug is log to stderr by default on server side (see here), we usually patch debug to another individual module

so you can add extra config to webpack if defining custom log method name and importing patched log library

e.g

import patchedToStdout from './patchedToStdout'
const myLog = patchedToStdout('mynamespace')
 
myLog('some log to log', 'stuffs')

in this case, we need to remove importing patchedToStdout also myLog's definition and invocation, so set loader's options methodName and moduleName:

{
  use: [{
    loader: 'remove-debug-loader',
    options: {
      moduleName: ['patchedToStdout'],
      methodName: ['myLog']
    }
  }]
}

those 2 options are array, so it supports as much as keyword you want to remove

Known Issue

removing multi line debug invocation isn't support yet, i.e

debug('a multi-line log message which would break code build',
      'use remove-debug-loader with this precaution')
