Additional context

honestly, I don’t even know how best to fix it, maybe we’ll create our own module for minification, but it may be overhead, maybe we should raise this issue html-minifier, any ideas?

@evilebottnawi I asked the html-minifier maintainers to upgrade to terser - what exactly is happening right now? Is es6 code just ignored or is it causing errors?

[alexander-akait]

@jantimon error, whaen people use es6 code

[alexander-akait]

@jantimon i have idea, maybe i can create hook inside terser-webpack-plugin and you will use hook for js minification, it is allow to use do better integration with terser?

html-webpack-plugin 4.0.0-beta.11 switched to html-minifier-terser
