A super simple way of adding api key authorization to your zeit/micro microservice.
import withApiAuth from '@xlnt/micro-api-auth'
export default withApiAuth()(myMicroFunction)
withApiAuth
also allows for some configuration like
getValidApiKeys: () => string[]
// pulls from process.env.API_KEYS (json encoded) by default
getApiKey: (req: IncomingMessage) => string
// pulls from req.headers['Authorization'] in the `Bearer :token` format by default
that's it.
