Every few months on one of the Elixir apps I maintain, Webpack would shit the bed and I’d have to spend a day fixing it. I’m not experienced enough with the front-end stack but I took a few hours to switch to Parcel and I’ve had ZERO issues since. This specific app has 2 large Elm components and Parcel handles Elm without any issues.
I have no idea what’s “better” than Parcel, but I was impressed with how simple it was to configure and how stable it’s been.
