Some useful custom utility🛠 functions for cookie handling in javascript

// setCookie("cookiename", cookieExist, COOKIE_EXPIRY_TIME);
// example - setCookie("username", cookieExist, (0.5 * 60 * 1000)); this cookie expires in 30 seconds.
// the cookie expiry time have to be in seconds so convert your time in seconds and after that pass it.

export function setCookie(cname, cvalue, exdays) {
    const d = new Date();
    d.setTime(d.getTime() + exdays);
    let expires = "expires=" + d.toGMTString();
    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}

// get a cookie and Its value
export function getCookie(cname) {
    let name = cname + "=";
    let decodedCookie = decodeURIComponent(document.cookie);
    let ca = decodedCookie.split(';');
    for (let i = 0; i < ca.length; i++) {
        let c = ca[i];
        while (c.charAt(0) == ' ') {
            c = c.substring(1);
        }
        if (c.indexOf(name) == 0) {
            return c.substring(name.length, c.length);
        }
    }
    return "";
}

// pass the name of the cookie as string which you want to check that if It exists or not.
export function checkCookie(cookiename) {
    let cookieExist = getCookie(cookiename);
    if (cookieExist != "") {
        return cookieExist;
    }
    return false;
}
