This is a fork of Svelte's template-webpack intended to play & experiment with HMR before it is officially supported.
It relies on forked versions of svelte-loader (fork), and svelte-dev-helper (fork).
Disclaimer I am not affiliated with svelte-loader team, so this may be completely different to what will eventually be implemented officially.
