ws has hardcoded localhost

[pabloveliz]

description

When using a different hostname (like IP) the HMR still points to localhost.

reproduction

parcel 1.4.1 using 0.0.0.0 as host and accessing from another machine by IP gives this error on the console browser

fix?

I manually edited src/builtins/hmr-runtime.js changing line 19 with
' + global.location.hostname + '
as suggested on this pull from parcel https://github.com/parcel-bundler/parcel/pull/476/files
