Simple mistake to ruin Webpack bundle optimization

• terser

  27 8,427 8.9 JavaScript

  🗜 JavaScript parser, mangler and compressor toolkit for ES6+

  

What you might not know, it's not the webpack that cleans up dead code per se. Of course, it does bulk of "preparation" work, but it is terser package that actually will *cut off * unused code. Terser is JavaScript parser, mangler and compressor toolkit for ES6+.

• webpack

  331 64,178 9.8 JavaScript

  A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.

  

Like you can see, messing up module interfaces prevents ModuleConcatenationPlugin (plugin for optimization) to do its job.
