Failed to minify code on npm run build

Question

I have finished my react application that was created with create-react-app , i have no issues running on local with npm start but when i try to build using npm-build

i get an error on minifying the code. I have tried cloning my project and trying to build it, i have tried creating a test project and trying npm build and am having no problems with it, it is only when i try to build my full project.

this is my error

> test@0.1.0 build C:\Users\Jonathan Stroz\Documents\HackerNews-Production-master
> react-scripts build

Answer 1

you're likely using an old version of react-scripts,try upgrading to react-scripts@>=2.0.0

Answer 2

It seems to be blowing up on this line of one of your dependencies. Looking through the create-react-app repo, I would guess that the options they're passing to UglifyJS in their Webpack config don't parse ES2015+. That newsapi package should probably be Babelified to support older versions of Node and older browsers, since usually folks don't Babelify their dependencies.

That package also doesn't seem to be browser-friendly, it looks like it's something that should be used server-side.
