无法在Express中使用Cookie-parser设置Cookie

Question

I have installed cookie-parser with Express to use within my React application. I'm trying to set a cookie so that I can begin looking into sessions for a login system.

When setting a cookie with the code below, the console log will only ever output Cookies: {} . I'm unable to get a cookie to set.

cookies.js

var express = require('express');
var router = express.Router();

router.get('/', function(req, res) {
    res.cookie('test-cookie', 'test-value', {
        maxAge: 60000
    });
    console.log('Cookies: ', req.cookies);
})

module.exports = router;

I'm using fetch('/cookies') to call cookies.js from my app.js main file.

When refreshing my application, the console log outputs Cookies: {} . I cannot see a cookie set within the developer tools Application tab either.

Is there any reason I'm unable to set cookies?

Answer 1

If I add the following to fetch('/cookies') , the cookie is then set:

fetch('/cookies', {
    credentials: 'include'
})
