Question regarding tree shaking

[vlio20]

Can you please point out which configurations are necessary for the tree-shaking to work?

I had the same question.

Looks like only the es2015 ones do the tree shaking.

Here are the results of npm run webpack and npm run webpack-es2015

Webpack 2.4 will support TS tree shaking I believe. Due to a bug in uglify js

@josephliccini So, I have been busting my ass for hours and wondering why its not working as expected because webpack + uglify is not supporting tree-shaking for TS? Can you please link me some note or article please? Need to share with the team.

@ibrahim-islam I think in the 'Known Issues' section of the Readme he goes over why TS Tree Shaking doesn't work in ES5 environments. I believe that TS => ES6 might work? To be honest I haven't tried.

The question is 。I use the Babili ES6+ aware minifer 。But the output file size which is larger than UglifyJS
