Hi,
I need to use the flag v3_singleFetch: false to be able to use Response.json in loader and actions.

Thanks.

I would recommend exploring the migration guide and starting the migration, and use in your production app when we release v1.
Sounds really nice ! This is based on v7 ?

Or does react-router better for speed?
There is quite a lot of good changes.
For example the typing of actions response
