I am able to set cookie in Postman, but not able to set it in browser

I faced the same issue, but then I tried this solution. My backend is built in Node.js, and for the frontend, we just need to add this line: withCredentials: true.

Here's what I did:

// my backend code

// just do this simple thing in your cors
app.use(cors({
    origin: 'http://localhost:3000',
    credentials: true,
}));

// route for login

app.post('/login', async (req, res) => {
    try {
        const { email, password } = req.body;

        if (!email || !password) {
            return res.status(400).json({ message: 'All fields are required' });
        }

        const user = await userModel.findOne({ email });

        if (!user) {
            return res.status(404).json({ message: 'User not found' });
        }

        const passOk = await bcrypt.compare(password, user.password);
        if (passOk) {
            const jwtSecret = process.env.JWT_SECRET;
            const data = { userId: user._id, email };
            const token = jwt.sign(data, jwtSecret, { expiresIn: '10h' });
            res.cookie('token', token, { httpOnly: true }).status(200).json({
                id: user._id,
                message: 'Login successful',
            });
            return res;
        } else {
            return res.status(400).json({ message: 'Wrong Password' });
        }
    } catch (error) {
        console.log(error);
        return res.status(500).json({ message: 'Something went wrong' });
    }
});

And here is my frontend code

const loginFunction = async () => {
        try {
            // Here just adding this simple thing....
            // and it worked for me...
            const config = {
                headers: {
                    "Content-Type": "application/json"
                },
                withCredentials: true
            }
            const data = { email: email, password: password };
            const res = await axios.post('/login', data, config);
            console.log(res);
            if (res.status === 200) {
                alert('login done');
                navigate('/home');
            } else {
                alert('login failed');
            }
        } catch (err) {
            console.log(err);
        }
    }

I am excited to share this solution with you! 🚀 I hope it's just what you needed. Happy coding ahead! 🎉
