[SOLVED] CORS with origin of "localhost" doesn't work

Code used: 
app.use('*', cors({
  origin: "localhost",
  credentials: true
}))
app.use('*', cors({
  origin: "localhost",
  credentials: true
}))
Issue: the Allow Origin header isn't sent but the access-control-allow-credentials is set

what's the request Origin? if nothing else, i'd assume you need to include the protocol

Origin is http://localhost:3000 Setting the origin in this code to http://localhost:3000 actually worked For future people that stumble across this post: set the origin paramter for cors on the backend to the exact base URL for the frontend. So literally just http://localhost:whatever port the frontend is on My frontend is using port 3000 So now I'm using 
app.use('*', cors({
  origin: "http://localhost:3000",
  credentials: true
}))
app.use('*', cors({
  origin: "http://localhost:3000",
  credentials: true
}))
Thanks for your help, @ambergristle
