Is it possible to run parcel serve with tree shaking?

[mcurros2]

Hi,

Is it possible to run parcel serve with tree shaking in place? We noticed that when running with the default config all code gets into a huge single bundle. When we run the build command, tree shaking is done as expected. Due to the size we are getting is difficult to debug on a mobile device.

We couldn't find anything in the docs.

Thanks!
