Note that Parcel’s plugin system is completely different in v2 and the implicit loading is gone.
That said, I very much preferred Parcel to Webpack as the JSON5 config was declarative and simpler and the HTML entry point.
Parcel in my experience still came with less issues than Webpack to be clear (and talking about the woes from Webpack was the main reason I commented). Now esbuild is on the front page and we can see some users saying it was a smart switch away from Webpack (https://news.ycombinator.com/item?id=28861732)
