We keep getting bug reports in the React repo that turn out to be uglify-es bugs. It seems that many people use uglify-es through webpack without realizing it's been abandoned and is known to be buggy and produce incorrect code.

If we could add an npm deprecation note to all 1.x versions of uglifyjs-webpack-plugin (which use uglify-es), it would be a little noisy, but I think that could help a lot.
sokra commented on Nov 7, 2018
You would get the message even if you are overriding the minimizer in webpack, since webpack depends on it.
sokra commented on Nov 7, 2018
The lastest version shouldn't be affected afaik because inlining is disabled by default
robpalme commented on Nov 8, 2018
Interesting. So Uglify was the first project to fix the constructor inlining issue back in Feb, then Terser cherry picked the fix. And the reason this it is a problem for webpack today is that Uglify-ES has not published since then, whereas Terser has.
sokra commented on Nov 8, 2018
Ok you've got me. Let's switch to terser for webpack 4 and don't care if it might be a breaking change...
Reinmar commented on Nov 13, 2018
I'm trying to understand why suddenly everyone started switching to terser. I understand that this is supposed to be a drop-in replacement for uglify-es and, hence, a transparent change to most of us.
