How to send cookies in express? - node.js

Question

router.post('/login', async (req, res) => {
const logInEnvironment = browser(req.headers['user-agent']);
const ipAddress = requestIp.getClientIp(req);
const userEmail = req.body.userEmail.toLowerCase();
const password = req.body.password;
// Form validation
const validation = await validateLoginInput(req.body);
// Check validation
if (!validation.isValid) {
return res.status(400).json(validation.errors);
}
// Find user by email
const auth = await Auth.findOne({ userEmail }, { userLoginInfo: 0 });
//Check if user exists
if (auth === null) {
console.log('aaaa');
res.cookie('send2', 'shhhhhent!');
res.status(200);
return res
.status(400)
.json({ authFailedMessage: 'Email or password is incorrect' });
} else if (auth !== null) {
bcrypt.compare(password, auth.password).then((isMatch) => {
if (isMatch) {
return res.cookie('failed', 'yess!').status(200).json({succeeded: 'hiii'})
} else if (!isMatch) {
return res.cookie('succeeedd', 'noooo!').status(400).json({failed: 'hiii'})
}
});
}
});
I have this code. But, the res.json has been returned without cookies.
Moreover, I added these commands in my index.js file
const cookieParser = require('cookie-parser');
app.use(cookieParser());
I also tested if res.cookie() was working in another route
router.get('/cookie', (req, res) => {
res.cookie('hellooo', 'hiiiiii')
res.send('woooorked?')
})
This was returning cookie and I can see that in the dev-panel on Chrome. What have I done wrong in the first code that cookies are not sent to the browser?

Answer 1

Did you try to split the code like
router.get('/cookie', (req, res) => {
res.cookie('hellooo', 'hiiiiii')
res.send('woooorked?')
})
Can you test with this code
router.post('/login', async (req, res) => {
const logInEnvironment = browser(req.headers['user-agent']);
const ipAddress = requestIp.getClientIp(req);
const userEmail = req.body.userEmail.toLowerCase();
const password = req.body.password;
// Form validation
const validation = await validateLoginInput(req.body);
// Check validation
if (!validation.isValid) {
return res.status(400).json(validation.errors);
}
// Find user by email
const auth = await Auth.findOne({ userEmail }, { userLoginInfo: 0 });
res.cookie('send2', 'shhhhhent!');
return res.json({ authFailedMessage: 'Email or password is incorrect' });
});
Then you check the header of the request and find the header name set-cookie, if it visible, you have got it
