Is it possible to tell if my function is running in a reactive context?

[tomasreimers]

I'm building a library on-top of mobx. I want to throw an error if a specific function is called outside of a reactive context (specifically, I expect it to be called from within a react component and want to make sure the observer HOC wasn't forgotten).

Is that possible?

mobx._getGlobalState().trackingContext == null

mobx/packages/mobx/src/core/globalstate.ts

Line 49 in 13a74fe

trackingContext: Reaction | ComputedValue<any> | null = null

mobx._getGlobalState().trackingContext?.toString().endsWith('.render()]') inside class component
mobx._getGlobalState().trackingContext?.toString().startsWith('Reaction[observer') inside func component
