While using cookies, you just need a route in the api to make an http request to remove the cookie that you have on the frontend. This is where cookies come in, you can send them whenever you make an http request without worry.Īnother reason is if you use localstorage, on the frontend you must ensure that the jwt is removed from localstorage when the user logs out. Sometimes I'm a little lazy and because of that I don't feel like constantly sending the jwt in the headers whenever I make a request to the Api. However, there are other ways to send the jwt to the frontend and today I will teach you how to store the jwt in a cookie. That is, the idea is to keep it in localstorage. If you have already read this article I created on how to create a simple authentication and authorization system with JWT, you must have noticed that I send the jwt in response when an http request is made from the login route. I am not going to create an argument here about what is the best way to store the jwt in the frontend, that is not my intention. Most people end up storing it at localstorage. ![]() tHeader("X-Set-Cookie", response.getHeader("set-cookie") ? "") Īllow x-set-cookie header in cors app.Although JWT is a very popular authentication method and is loved by many. Make a work around for localhost // if origin localhost ![]() Set cookie as you normally would res.status(200).cookie("token", token, cookieOptions) What I ended up doing, maybe it helps someone. So for localhost a proxy sounds like the best way around this. I want to have http only cookies to safer store a token. Secure: app.get("env") = "development" ? false : true,Īfter more then a day of trying all your suggestions and many more, I surrender.Ĭhrome just does not accept my cross domain cookies on localhost. SameSite: app.get("env") = "development" ? true : "none", Remember sameSite works with express latest version only as at now and latest chrome version only set cookie over https, thus the need for secure option. I set my origin dynamically using config npm module.įor localhost: you do not need to set sameSite and secure option at all, you can set httpOnly to true for http cookie to prevent XSS attack and other useful options depending on your use case.įor production environment, you need to set sameSite to none for cross-origin request and secure to true. In CorsOption: Set origin to your localhost url or your frontend production url and credentials to true The desired result is something like this:įor express, upgrade your express library to 4.17.1 which is the latest stable version. Reads it from the cookie when needed and writes it in the header of every request. The second part is the one that specifically handles an anti-CSRF token for all requests. This practically means that an OPTION request will be send first, so that you get your cookies and the authorization token among them, before sending the actual POST/PUT/DELETE requests, which need this token attached to them (in the header), in order for the server to verify and execute the request. Res.cookie('token', 'xxx-xxx-xxx', ), is what you need in order to send each request with withCredentials: true option. I'm using the request module in a React-Redux app to issue a request to a /signin endpoint on the server. I don't see any CORS errors, so I assume I'm missing something else. Yet, I can't see a cookie being set in in the Application tab under Storage/Cookies. ![]() Set-Cookie: token=0d522ba17e130d6d19eb9c25b7ac58387b798639f81ffe75bd449afbc3cc715d6b038e426adeac3316f0511dc7fae3f7 Max-Age=86400 Domain=localhost:4000 Path=/ Expires=Tue, 21:11:36 GMT HttpOnlyĬontent-Type: application/json charset=utf-8įurthermore, I can see the cookie under Response Cookies when I inspect the traffic using the Network tab of Chrome's developer tools. These are the response headers:Īccess-Control-Allow-Origin: Vary: Origin, Accept-Encoding It seems I'm receiving the right response headers in the browser, but unfortunately they have no effect. ![]() I am attempting to set a cookie for an API that is running on localhost:4000 in a web app that is hosted on localhost:3000. How to share cookies cross origin? More specifically, how to use the Set-Cookie header in combination with the header Access-Control-Allow-Origin?
