cookies.remove('abc') not working in reactJs

import Cookies from 'universal-cookie';

const cookies = new Cookies();
cookies.remove('abc');

console.log(cookies.getAll());

It is still printing my abc cookie.

If you are setting the cookie on a response in a login route/controller in express backend for JWT and are using 'httpOnly' option, you are unable to access the token from the client/react, even when using a third party library like 'universal-cookie' or 'document.cookie'.

You will need to clear the cookie on the response from the backend e.g. when a user logs out in the logout controller as detailed below.

Front-end:

// React redux logout action
export const logout = () => async (dispatch) => {
    try {
        await axios.get('/api/auth/logout')
        localStorage.removeItem('userInfo')
        dispatch({ type: type.USER_LOGOUT })
    } catch (error) {
        console.log(error)
    }
}

Backend:

const User = require('../../models/userModel')
const generateToken = require('../../utils/generateToken')

// @desc    Auth user & get token
// @route   POST /api/auth/login
// @access  Public
const login = async (req, res) => {
    const { email, password } = req.body
    try {
        const user = await User.findOne({ email })
        if (user && (await user.verifyPassword(password))) {
            let token = generateToken(user._id)
            res.cookie('token', token, {
                maxAge: 7200000, // 2 hours
                secure: false, // set to true if your using https
                httpOnly: true,
            })
            res.json({
                _id: user._id,
                name: user.name,
                email: user.email,
                isAdmin: user.isAdmin,
                token: token,
            })
        } else {
            res
                .status(401)
                .json({ success: false, message: 'Invalid email or password' })
        }
    } catch (error) {
        res.status(500).json({ success: false, message: error.toString() })
    }
}

// @desc    Logout controller to clear cookie and token
// @route   GET /api/auth/login
// @access  Private
const logout = async (req, res) => {
    // Set token to none and expire after 1 seconds
    res.cookie('token', 'none', {
        expires: new Date(Date.now() + 1 * 1000),
        httpOnly: true,
    })
    res
        .status(200)
        .json({ success: true, message: 'User logged out successfully' })
}

module.exports = {
    login,
    logout,
}

I just add this for people who may have similar problem in future, just like I had today. This may be an issue with asynchronous actions. Setting, removing cookies is asynchronous.

Cookies need to have both path and domain appended to them to be removed. Try this:

cookies.remove("abc", {path: "/", domain: ".example.com"})

May be you need to do something like

cookies.remove('abc', { path: '/' });
