I used to love Webstorm. It works great for a simple layout and the code inspections and suggestions really speed things up. But a modern setup with ES6, Vue and Webpack almost completely render the IDE unusable for me -- everything slows down to an unbearable speed and most of the inspections either don't work at all or trip over themselves. With that, I've switched to Sublime Text almost exclusively. Any pointers on how to adjust Webstorm, apart from using TypeScript?
Webpack watch mode is how I use it. On top of that you can run webpack outside of the IDE, just like you do with sublime text. My setup is i7 with 16 GB, and only electron app ( webpack + react ) will make my setup really slow. Anything else usually is swallowed by webstorm
