What is the purpose of supports property in React












1















I am working with a legacy code and I am wondering what is the support property that is being used in most of the components. I haven't seen it yet in documentation, and can't find any info about it.
This is how the components look like with that property:



const Panel = connect(mapStateToProps, mapDispatchToProps)(injectIntl(handlingForm({
form: formName,
enableReinitialize: true,
})(PanelImpl)));

Panel.supports = (bp, apCodes) => bp === handlingCodes.PANEL|| actionPoints.some(ap => apCodes.includes(ap));


I have found that it is being used to check whether to render the component or not:



 {Panel.supports(bp, apCodes)
&& (
<Panel
submitCallback={submitCallback}
readOnly={readOnly}
readOnlySubmitButton={readOnlySubmitButton}
apCodes={apCodes}
/>
)
}


So, I guess what I am wondering is, what is being returned from connect function, and does support property exists in the returned object or we can add any property to it, like supports is added here?

  • That looks like a very project specific thing. Keep in mind that you can arbitrarily add new properties on any JavaScript object and technically functions are objects.
