I am developing a little web app where i wanted to set cookies from the server side with express. I'm using firebase functions, express and CookieParser. When i deploy my project into firebase cloud works perfectly, but when i serve from my computer 'Set-cookies' doesn't appear in the header and there are no cookies store. Why is this happening?

node-v8.11.2

app.use(cookieParser());    
app.get('/cookie',(req,res)=>{
   res.cookie("test","This is a test");  
   res.end('test');
});

EDIT: I fix it by setting cache control to private.

app.get('/cookie',(req,res)=>{
   res.setHeader('Cache-Control','private');
   res.cookie("test","This is a test");  
   res.end('test');
});

One difference that comes to mind is localhost is probably http, whereas hosted firebase will be https. – jrasm91 May 21 '18 at 02:06
@Jason any idea to solve this while serving in local? – Facundo Silva May 21 '18 at 02:13
Can you try setting httpOnly and or domain in the cookie options? – jrasm91 May 21 '18 at 02:21
@Jason I’ve already try it... still not working – Facundo Silva May 21 '18 at 02:40
I copy/pasted your code locally and ran it - worked as expected. How are you calling this endpoint? Are you using the Fetch API? – jrasm91 May 21 '18 at 05:10
@Jason did you run it as a firebase funciton? If you did, which version of node Js are you using? – Facundo Silva May 21 '18 at 09:28
