Congrats to the Parcel team! Really great work. Having used Parcel in personal projects for the past year, it really is a great user experience.
Despite what people says in the comments, Parcel has its (great) value. The ability to import a rust file directly and have it compiled to a web assembly module for example, is a great piece of engineering and exceeded my expectations for web build tools. Parcel also hits the sweet spot where it's both zero-config, and easy to customize if you find the need.
Honestly? Parcel has a better experience than your C++ build tools. Be it CMake, Ninja, or whatever build tools people use in 2018.
