So this is how a senior dev works and explains things. Simply amazing. Thank you for these videos.

Dude, this is by far the best tutorial series I have seen. Unparalleled quality. Thankyou!

[Alibeee]

I've been following your tutorials on Node, Express, and working my way to Mongo for my project this week. I've told my professor about how helpful your videos are and I've been spreading the word to my classmates. I'm surprised you don't have more views on these tutorials. Thank you for your help!

[stevieholland]

I just wanted to say I appreciate you and what you do. Your videos are well explained, very thorough, but also digestible. Some instructors get a bit too technical, or lack enough technicality to fully understand what is happening. Yours are right in the pocket. Thank you, kind sir. You have provided a lot of clarification for me.

be very careful when testing this specific implementation with nodemon vs a normal server. nodemon restarts after any file changes, including changes to models\users.json. This allows each function to get the updated state of refresh token. If you run this without nodemon, your refresh and logout functions will reference old versions of the users.json data that do not include the refresh token from the auth. This causes some unwanted behavior that took me quite a while to catch. As always, thanks @DaveGrayTeachescode for another great and comprehensive lesson

hey dave this series is really helpful. the way you split things into routers and middleware has been eye-opening. so simple

[xifrefont]

I usually stay away from tutorials but the content you post is insanely good, I have actually learnt a lot from your channel. Since I discovered it my skills with javascript have improved a lot. Thank you so much

[tabliqatchi]

This is masterpiece! 😍 I've thanked on all videos of you I've watched in the comments, and I will do it again on this one because you deserve it. Please keep creating content, I'm seriously worried you might lose interest in it at some point and we lose more content created by you, because you're so good.

[ogundekoadegbenga]

Thank you Dave. I read through all the comments and your responses to the questions asked which adds more to what has been learned in the video. Thanks again.
