webpack is great. HMR and code-splitting are killer features. Only thing that I'm worried about is tree shaking. There are a couple of long standing issues about problems with classes and export all statements. Rollup is missing code-spliting, webpack doesn't do tree shaking well and complains about bundle sizes. Not sure what to do. If somehow rollup could be integrated, that would be perfect.

We are really excited to work with Rich Harris on adding scope inlining, (Rollup'y) features. We were waiting to release 2 first :-D

HMR & code splitting weren't even original to WebPack... where does this fiction come from that it introduced them?

(Side note - I have a complex app but still get ~1sec build times, why the fuss over HMR?)

Not having to refresh which means preserving state. If I have a modal opened and I want to make a change to the modal UI, if I refresh I would have to reopen the modal. With HMR the modal just rerenders.

Also even if you have a fast build, refreshing might require refetching data from a server.

In any case browserify also has HMR and it's great.
