Thank you Pedro, your videos are always on point and straight forward great

[@jameshalstead6742]

How this hasn't received more thumbs up than this I have no clue. I've been doing this for a while now but still a newbie. I never paid attention to what middleware was until recently but still didn't know exactly how it worked. This made it click, Good job Pedro! In my opinion, you are the best React KZbinr, and I highly recommend you to everyone who is trying to learn or improve their React skills.

[@PedroTechnologies]

Glad to hear! Yeah this was one of my favorite videos to make cause I feel like middlewares are often overlooked by beginners. But tbh my videos do well based on the youtube algorithm. Not always the best videos gets the most views/likes hahaha Thank you for watching :)

[@nirajdeshmukh7514]

hey pedro! I am really thankful for this video. I understood very well by watching this video! 😊

[@ashleyyong4963]

hi pedro! thanks for this video. was really helpful! love from Singapore

[@richcaro3132]

Great man. I could understand the functioning of next() and creating a middleware. I think your explanation is flawless. Being so busy, you could spare some time and educate us. Thank you..

[@PedroTechnologies]

Glad it was helpful! I appreciate the support!

[@shockwave8429]

Great video Pedro

[@softblood1941]

Hi Pedro. I would love to see you making a full stack crud app, full stack login authentication app using node, express, ejs, MySQL. I think ejs is very welcomed. Keep up the good work!

[@PedroTechnologies]

Hey, I plan on making a full authorization / authentication application tutorial again! I may use ejs just for visual, but I was actually planning on just making this work with an api tester like postman since I want to focus on the api rather than the ui!

[@softblood1941]

@@PedroTechnologies cool but the connection of front to back is also important to teach. and i belive ejs and node is perfect.

Nice !! i've know it nahh!! lmfao try it with passport js :) with mvc implementation

[@PedroTechnologies]

Awesome! I can definitely make a vide on it!

[@conspirisi]

Could you do something on fundamentals of security? Like am I right in thinking anyone can run your serverside code from the devtools? I know this is prevented to some degree with authentication, but code that isn't that sensitive on the server, can I just run express js functions, by calling them from the dev tools?

[@PedroTechnologies]

Hey, so you can't actually run express functions from the devtools cause all of that belongs to the server and not the browser. WHat you can do is make api calls from the devtools, so to protect that you can add some sort of authorization token.

[@conspirisi]

@@PedroTechnologiesthanks for replying, so for example say I've got a "to do list" application that writes entries to a database. I write to database via code that's called from a clientside js file (accessible to public) this code calls a server side function (not directly accessible to the public) that then writes the database. What stops a malicious user finding that code in the clientside and continously running it (either via the console, or just clicking in the browser without knowing any js) and using up your quota of requests say from a cloud db provider? My concern is that I'm going to have write custom code to prevent that? That's all.

[@usmanmughal5916]

Nice video didnt even watch yet :P

[@PedroTechnologies]

Hahaha Hope you enjoy!

[@exe.m1dn1ght]

[@arjay_2002]
