minify-dir

Minify typescript/javascript source codes in specified directory with options to remove debug codes.

---

This module was inspired by: https://github.com/crissdev/gulp-remove-code

Usage

Given a sample JS file src/dir1/file.js:

//removeIf(prod)
console.log('This will be removed if options.removeCode.prod is true')
//endRemoveIf(prod)


//removeIf(debug)
console.log('This will not be removed if options.removeCode.debug is false')
//endRemoveIf(debug)

your-minify-script.js

import minifyDir from 'minify-dir'
// or const minifyDir = require('minify-dir')

const options = {
  minify: true,
  copy: true,
  tsc: {},
  basePath: '.'
  dest: `${process.cwd()}/release`,
  excludePatterns: [/\.git/],
  removeCode: {
      prod: true,
      debug: false
  }
}

const src = 'src'

minifyDir(src, options)
  .then(() => console.log('Done processing...'))
  .catch(e => console.log('An error ocurred!', e))

Params

• The first param is the directory to be minified. All contents of the src directory in this example are going to be processed and the output will be saved in release directory. So if you have a file src/dir1/file.js, it will be saved in release/dir1/file.js. src can also be an absolute path in which case it ignores the options.basePath.

• The second param is the Options object.

Options

minify - If object is passed, the object will be passed on to uglify-js. If value is false, the output js files are not minified. Default is true, calls uglify-js without options.

copy - Copy none-js files from src to options.dest. Default true

tsc - A typescript compilerOptions object used in transpiling typescript source. Default is {}.

basePath - The path where to start looking for the options.src and where to store the options.dest directory. Default is process.cwd().

dest - The output folder. Default is process.cwd() + 'release'. Can also be an absolute path in which case it ignores the options.basePath.

removeCode - The values passed to remove code conditions. Default is {}.

excludePatterns - RegExp patterns used to match when excluding files. Excluded files will not be copied nor minified. Default is [/\.git/].
