How to get features in typescript without casting? about meyda

[hughrawlinson]

Hi!

I've actually been working on a PR for this - it's not ready at the moment and the complexity make me think maybe it's not the right thing to merge for maintainability reasons. I would love feedback on the design described here though!

For now, I would suggest writing a user defined type guard function.

Hi @hughrawlinson thanks for the answer!

I was thinking to replace .get to my own typed get function:

type FeatureName = keyof MeydaFeaturesObject
function getFeatures <KS extends FeatureName>(keys: readonly KS[]): Pick<Features, KS> {
   return meydaAnalyzer.get(keys)
}

the new extract API seems very interesting! 👏
