I ran npx tsdx create mixpoint and chose the react option, then went into /example and ran npm install then npm start and ran into this:

PS C:\dev\mixpoint\example> npm start

> example@1.0.0 start C:\dev\mixpoint\example
> parcel index.html

You’re welcome to workaround by upgrading to the beta yourself

Sadly, this will break hot module reloading. I couldn’t find any solution so I gave up.

Right now, I use parcel v1.12.3 which doesn’t have the above issue.

// on example/package.json
// From
"parcel": "^1.12.3",

// To
"parcel": "1.12.3",
