Your complete guide to understanding the express-session library

[@sourabhkhandelwal689]

This is one of the most under-rated KZbin channels. Don't know why it has so low views and likes. Seriously, you have amazing content.

[@evicoach]

I always come here when I want to understand something deeply, thanks for the good work @zach

[@senti3ntb3ing96]

I've watched quite a few tutorials about sessions and express lately and I think that you do the best job of them all, very well explained and answers a lot of questions others skip over

[@lscodeschool957]

Hello @Zach, you have no idea how i much appreciate this tutorial. I have been searching thru all sorts of tutorials for a good understanding of how to persist user login and sessions and cookies and all that, but none could explain as simple and deep as you have. See, Zach, You have done, if not, the best tuts ever tuts on this topic. I will follow you throughout. kindly let me know which other ways i could reach you. thanks so much. I will recommend your channel to all my students. thanks so much

[@SridTech]

I too cannot contain the excitement of watching this video.

[@zachgoll]

So glad you've found it helpful, and thanks for sharing! I created this one because I couldn't find it myself so I'm glad it is resonating.

[@Konstantin19877]

Best video ever. I wonder what happens to session data in Mongo when cookie expires, data gets deleted from db or I need to handle it? Clear outdated records?

[@mattpickel223]

Love this style where you break down what's going on behind the scenes instead of just showing implementation. Great video!

[@gyrips4284]

Thanks so much man! I've been trying to learn passport.js for WEEKS and none of the courses worked AT ALL!! I really appreciate what you're doing here!

[@xianbalderrama]

[@usmanmughal5916]

You are a real lifesaver. This is a million dollar video. Very under-rated and full of potential channel. All of your followers appreciate your efforts, but it's nothing compared to your hard work and detailed explained topics. Absolutely great video.

[@zachgoll]

Thank you!! 🙏

[@usmanshah5862]

I will try to make the exact video playlist for the people of my region. This is such useful information...

[@bn2005]

[@keninswed]

[@candidatesvoice8826]

I used this with a combination of postgres-sql, connect-pg-simple, and it worked like a charm. Wonderful my man.

[@SridTech]

Actually you should not hide the subscriber count. You are the most under-rated youtuber. Now I am gonna check your channel everytime I am stuck with something. Please make sure to add contents like this continuously. These 25 minutes gone like a breeze. Keep up the good work.

[@tech3425]

It's nice to see how everything works under the hood, instead of blindly adding the Passport Js library.

[@andrewpratt3861]

Really well-explained. You did a great job giving full information about both concepts and implementation. Thanks for this one!

Thank you very much for your efforts. Great tutorial.

[@TheMakeupmonika]

Love your videos Zach !!!!

[@siddhantraj5323]

Brother seriously" U nailed it

[@SugizoYoshikiX]

So express-session automatically generates session ID and attach that to set-cookie header? We don't need to manually code something like: resp.setHeader(set-cookie, [sessionID])?

[@EvaXdelo]

your playlist most useful i have learn from it thank you and keep going

[@scottsmyth3251]

Thanks for these videos man, great stuff

[@AtmaniChouaib]

thank you great explanation, made it super ez to understand

[@discusstime]

Hello @Zach, I have a question about sessions. How can you create a session that has a frontend timer and if you reload the page its going straight down, without reloading the time

[@MrFsudude]

This is really good content. Great explanations

[@alexandermarkin1200]

I love you, man! You are a life saver!

[@martindm6019]

This tutorial is excellent!

[@fiendsgaming7589]

best explanation ever! Thank You!

[@SmokyBigSmoke]

This is exactly what i was looking for..tysm

[@ihsannuruliman3656]

one quick question Zach, if we change the expiration date in browser's cookie, will it also change in the database?

[@codemind1822]

I have an error like Property 'viewCount' does not exist on type 'Session & Partial'.

[@tungtran4019]

love your tutorials! thanks a lot

[@nickwoodward819]

Is there much point adding properties to sessions if they're invalidated on logout or page close? Or can you have somesort of backup/soft delete table where you can revive old cookies?

[@HarshitSharma-kk6yz]

this tut.is actully good I really like this ..keep it up

[@usmanshah5862]

Zach, the cookie is not being written in response header but i can see it in the Atlas DB. Please reply, this is killing me. I've been looking to find the solution for 5 hours.

[@flowerofash4439]

6:58 the explanation of session store & connect-mongo library basically saving your cookie information into the database

[@zedshockblade7157]

Thanks. I was confused on how to add a property to the collection 'session' like 'user-id' if the library automatically adds the data.

[@sagivalia5041]

So if for example, I want to display the user's name after he logged in, I: 1. Initialize the session as soon as he successfully logged in 2. Saves the user's cookie.sid in the db along with his name 3. Retrieve from the DB the name which corresponds to the request's cookie.sid Am I correct?

[@brycegoh9399]

Hey, I would like to clarify some doubts. If the maxAge is set to a timethen wouldn't the cookie be deleted by the browser even though there is user activity? Wouldn't that affect user experience? Is there some kind of best practice?

[@firojsiddiki2750]

video was preety good but my one question remain unanswered in the video. What happens to the sessions in the database if the cookie in the browser gets expired ? Does it get auto deleted or what ?

[@usama_khalid]

best video on this topic...

[@jimshtepa5423]

Zach thank you for your time to put it together. A quick question: how does browser know to which request among many possible requests to attach this particular session to? what if browser is sending requests to five different servers of which there have set cookies to the browser and the other two do not use sessions, how then does the browser keeps track of what session needs to be sent to what server?

[@zachgoll]

Great question. This gets into a slightly complicated topic of load balancing and managing a cluster of session stores. Generally, if you’ve got multiple servers, you’d be setting up something like Redis to centrally manage the sessions. So basically, all the servers would reach out to a central Redis instance (or cluster), which keeps track of all the sessions in one spot. This way, both the browser and server are stateless, and all the sessions are semi-persistent in Redis.

[@manudeepherle1251]

This helped me a lot. Thanks!

[@eldinedy6837]

Can we use express-session to protect routes by roles? how could that be done? for example, i don't want to user have access some pages that super admin can?

[@9gager87]

This was a great video, keep it up!

[@hoquang1386]

this is super useful. Thank you, sir.

[@chidibede2417]

You are a lifesaver, Thank you!
