Authentication in React app using Flask Server-Sided Sessions

Authentication in React app using Flask Server-Sided Sessions

In this video, I show you how you can authenticate your React application using Flask server-sided sessions. This is a very easy way to authenticate clients using HTTPOnly cookies, and the session data is stored on the server-side, while the client only receives a corresponding session ID.

I'm making a internal system for my company, using flask and react, and I have no idea how auth works (until now, I was storing a token in client-side xD). Appreciate your content! :)

Rarely comment but had to say great job. I'm a CS student trying to redo a group project originally built in flask to a flask API and React front end. Flask is so easy handling current_user with jinja, but you literally answered all my questions in a single video. Now I just need to get to work. Great job.

That helped a lot. I was working on something like that and missing a few things here and there while implementing the sessions. You just earned a sub dude <3

Bro, u are a legend! You explained everything so well i understood flask and implemented it for my vue application. Thank u so much!

[Pouckimon]

Thanks man! This helped me a lot! Saw some less efficient/safe ways to do it on Youtube and I knew I had to look further. This looks like the best way to do authentication. Very well explained! Thanks!

Great, just what I was looking for, thanks bro

[ИгорьКлещёв-нэ]

Thank you so much, the video is amazing, everything is explained well, the pace is great, this is exactly what i was looking for!

Learnt so fucking much from this video thanks, I am used to authentication in Nodejs/Express, its nice to see it how to do it in Python to, pretty much the same thing. Also so happy you used Typescript!

I get a TypeError: cannot use a string pattern on a bytes-like object when I run your code (it happens after login or register, when i should receive the cookie)

[AudreyVasher]

this is amazing! Thank you for your help.

Thanks for the tutorial! Side note what VS theme is that? It looks really good

When I log in the cookie is being set, but when I log out the server responds with internal server error, and gives KeyError: user_id, basically it is not able to find the cookie although it works fine with postman but when I try this using browser this error occurs

thank you awesome clear and concise video!

If the only scopes you are asking for is “know what servers you are in” is server sided sessions really needed? If someone uses xss on your site, thats more of a concern if the token being stored doesnt have sensitive scopes such as join servers, access email… etc

In terms of discord oauth

[Deccoyi]

Thanks. great tutorial. I have one question. Since cookie is visible on the browser does it mean anyone that has that cookie can log in as the user? Or the library checking something else to prevent it?

What was the reason to install redis to not use it at the end? Also getting the CORS errors, when running the code on the other machine.

Thanks for the tutorial!

If multiple people are logged into the website, how does session know which user to pop if they all have the same key "user_id"?
