Set Cookie as post response?

It could very well be that I am missing something basic here, but why cannot I set a cookie as a response to a cookie? Here is my over simplified code that does not set a cookie for some reason: app.post('*', (req,res) => { req.session.userName = "John Doe"; res.end() }) My use case would be when the user logs in, the body of the post is parsed, and the name she logged in with will be saved to the session cookie.

Setting cookies as responses to get requests is not a problem.

Hi there. I figured it out! I was making the POST with fetch() on the client side, and I needed to add credentials: 'same-origin' to the fetch() configuration object. : ) I still do not know why the browser will not render text or html when I respond to a POST request with that, but that’s a topic for a different forum. (You can see the body of the response in the browser dev tools, but for whatever reason, the browser doesn’t render it.) Anyway, thanks for the help!!

Hi! Thanks so much for getting that for me! I was thinking of looking into this today, but I think I instead need to focus on https://github.com/expressjs/generator/pull/190#issuecomment-361248460 as it sounds more urgent I think. Once that is done, I’ll come back to this next, but it is unlikely to be today, very sorry 😦
