Global spring configuration

[Emiliano-Bucci]

Hi! I was looking into the Globals but I couldn't find anything related: is there a way to set a global spring configuration without having to pass it to every useSpring, set, ecc call every time? I guess it would be useful to do that

[joshuaellis]

Like a default config?

[Emiliano-Bucci]

@joshuaellis I didn't know it! But for some reason I cannot add a config prop. I'm using react-spring v^9.1.1

Do you know what could be? Or am I doing something wrong?

EDIT: It seems only a type issue, I can actually pass the prop and it works. Maybe I can create a small PR? :)

[joshuaellis]

Absolutely! Please do, I can look closer before we merge too 🤓

@joshuaellis I was investigating further, and i've realized that it isn't working, somehow. Now, probably there're lots of things I'm missing here, but as far i can see from the logs, i see that the value passed to the <SpringContext /> are only used to populate the defaultProps:

This is a log example of a simple spring i have: the defaultProps are populated with the config passed to the <SpringContext />, but the animation config currently used to animate is the one in the opacity.animation.config, which is the default one used by react-soring under the hood (that can be override by passing a custom config to a single spring hook).

AFAIK the default props are merged with the props you pass. I'm not sure if it's deep merge so if you define a config, is that merged too or simply overwritten? I'd assume it's merged otherwise your spring might have mass but no tension?

Looking in the source would give you some answers I reckon.

Thanks for the info; i still need to investigate better and understand better the flow :)
