How to Create a Web Server (with WebSockets) Using an ESP32 in Arduino

Note that we use the ESP32 as an access point (AP) here to simplify the process. You can do away with the access point, if you wish to have the web server on your local network.

WebSockets provide a persistent connection between a client and server so that either party can send data at any time. They are very useful in things like networked video games, but they can also be applied to IoT devices, if we need fast control of hardware over a network.

So I searched google and YouTube for weeks looking for a detailed yet to the point tutorial about this very topic, and the ones I found are either too complicated or expecting me to be a web developer. Then only today, YouTube simply suggest this video to me like I never searched for such a thing!!
It's exactly what I'm looking for as if it was made specifically for me!! why YouTube!! why!! 😩

This video should be the top result whenever someone search for "ESP32 webserver"

Thank you so much for this video as I find it perfect!

I just got an ESP32-C3-mini-1 and I had already set up the boards and device to ESP32-C3. Following your presentation, the code worked fine on it. On to the second part! :) Thank you - whoops, this is the second part. I"ll post this back on the first.

Best explanation I have ever seen. Thank you.

Good work Shawn! Done as you had explained and it works perfectly!

Wow nice timing! Exactly what I need for my next project. ❤️

Shawn - Great video! It really helps me out with a project. Hope you are doing well and staying safe.

Clear (if a bit fast) description of how to do everything. Do you have an updated version for Arduino 2.0 IDE? The installation of tools doesn't seem to work the same.

„A few months ago“ - man, feels more like ages. But as always, great work, clean code. Minor improvement could be made trough the use of a captive portal, which opens directly after connecting to the access point. thumbs up

Well done, and thanks for not dragging it out.

Incredible, I had no idea this was possible

Very nice guide and at the speed it must be :D

hey, my esp32 is connected to weight scale(weight scale like we see at market) okay and i want to said this weight data to a server . how to do this plzzzz help

[SparQz]

Could I use this to send pwm signals to a dimmable led driver and make a slider on the page? Sorry I'm new to esp 32 and not sure how much it's capable of.

Thanks, great video and you code is amazing clear, reusable.

I want to run a nodemcu with a servo. Is it possible to to have it connected to my wifi, and connect to it using my cell network?

You have great content!!! May I ask Why you take so long time to upload?? Keep this channel live. This is a really good channel!!

Respected *Shawn Hymel* sir,
I am a student, and literally the way you have teached electricity and electromagnetism is infinite wonderful!❤️ You have given us knowledge in the best way which nobody has ever given to us!
In india, teachers don't teach us correctly, they just make. Us gulp the text written in the book.
I request you teacher Shawn hymel that please try to teach us more physics like that you did in past(electricity, electromagnetism)
I know making more such videos will take a lot of effort! But please try to help,
Hope you will reply sir🙏🙏🙏👍❤️😁

[MrCamdere]

wow it looks like easy i will try it thanks for your time ! :)

[yrrlicht]

short note for everybody doing this right now, you need an older version of arduino (1. smth) because in newer versions it doesnt show the arduino instalation folder

Great tutorial! I'm getting a "Error mounting SPIFFS" in the Serial Monitor window. Any advice on what I may be doing wrong? (sketch compiles and uploads to the ESP32 just fine--all libraries installed)
