问题
When I run webpack-dev-server, with a publicPath of /dist, I'm able to see live-edits for my app (changes to html, styling, js). However, when I compile the app into a production build, the stylesheet and javascript load from /dist/main.css and /dist/main.js instead of from main.css and main.js
The problem seems to be with the publicPath setting. If I remove publicPath, the app compiles with main.css and main.js, but I'm not able to see live edits. However, if I keep publicPath: /dist I can see live edits, but now I get /dist/main.css and /dist/main.js
