The order in which you use middleware in Express matters  middleware declared earlier will get called first  and if it can handle a request  any middleware declared later will not get called   If express static is handling the request  you need to move your middleware up      need cookieParser middleware before we can do anything with cookies app use express cookieParser         set a cookie app use function  req  res  next         check if client sent cookie   var cookie   req cookies cookieName    if  cookie     undefined           no  set a new cookie     var randomNumber Math random   toString        randomNumber randomNumber substring 2 randomNumber length       res cookie  cookieName  randomNumber    maxAge  900000  httpOnly  true         console log  cookie created successfully        else          yes  cookie was already present      console log  cookie exists   cookie          next        lt -- important          let static middleware do its job app use express static   dirname     public       Also  middleware needs to either end a request  by sending back a response   or pass the request to the next middleware  In this case  I ve done the latter by calling next   when the cookie has been set   Update  As of now the cookie parser is a seperate npm package  so instead of using   app use express cookieParser       you need to install it separately using npm i cookie-parser and then use it as   const cookieParser   require  cookie-parser    app use cookieParser

Not exactly answering your question  but I came across your question  while looking for an answer to an issue that I had  Maybe it will help somebody else   My issue was that cookies were set in server response  but were not saved by the browser    The server response came back with cookies set   Set-Cookie my cookie HelloWorld  Path    Expires Wed  15 Mar 2017 15 59 59 GMT    This is how I solved it   I used fetch in the client-side code  If you do not specify credentials   include   in the fetch options  cookies are neither sent to server nor saved by the browser  even though the server response sets cookies   Example   var headers   new Headers    headers append  Content-Type    application json    headers append  Accept    application json     return fetch   your server endpoint         method   POST       mode   same-origin       redirect   follow       credentials   include      Don t forget to specify this if you need cookies     headers  headers      body  JSON stringify           first name   John           last name   Doe              I hope this helps somebody
