ESPAsyncWebServer | Async Web Server for ESP8266 and ESP32

I would like to use the web server library ESPAsyncWebServer to create an API on my ESP32. But I was wondering, since the web server most likely runs on the secondary processor, do I need to make accessing data thread safe? So that the main loop and the web server can both access the data?
Or are they actually running on the same thread an I don't need to worry about it?

Tried to position text In an Image exactly like in the example from w3schools. It works fine in my space at w3schools. When I look at the css in the browser:

I'm developing on an ESP32 with vscode and the ESPAsyncWebServer and Wifi libraries. I'm tring to make my own wifi manager, so I'd like to put some function in a class, but I've some trouble to point to member functions.

I have this definitions without class:

I am programming for the ESP32 (a sort of Arduino like chip). However, to easier/faster find compiler errors/warnings and later make a sort of virtualization on the PC, I like to compile the code also on a PC (using Visual Studio).

However, I cannot get the following code to compile on a PC (while it compiles in the Arduino IDE for ESP32):

I'm trying to receive a data from one esp32 to another. I'm also doing some looping with delays for reading a sensor data and switch on/off relay cooling. This device also use ESPAsyncWebServer as API server (not included in code for the size). I'm receiving the data from one eps32 in POST request to API right now. I would like to change this as to be able to recieve with esp_now. I was doing some experiments, but the data receving is delayed because of delay method in loop. Is there a way to make this asynchronized as for example the ESPA above?

I also tried a way with comparing a milis() (time) to wait for a loop, but I thing that is too "resource consuming" task, to let it compare in full speed in loop like a vortex forever.

here is my loop it's just a simple loop with some vars and delay function for example

First the problem.

The user can upload file from the web with ajax. If the file is relatively big, the uploading takes a while. If the user's connection is lost or something happens during the uploading process, the file is going to be damaged or empty.

How should I secure the upload process so the file remains the same if it fails for some reason?

I'm using the following libraries on the Arduino ESP32:

• ESPAsyncWebServer
• LITTLEFS

I have a basic file upload handler on my esp32 which looks like this:

i am working on esp32 module, i have made a web interface to show the sensors values, using :

ESPAsyncWebServer.h library and AsyncWebServer server(80);

but now i want to add a Camera,but for this latter i have to use :

ESP32WebServer.h library and ESP32WebServer server2(80);

How can i do to use this two server in the same program please ? when i tried that, i can compilate the sript, but only the server witch begin.server() or begin.server2() is first it will work, the second no !!

i also tried to do server.end() server2.begin() to use the other server, but it does not work also (it says server2.end() does not exist for ESP32WebServer.h library)

Thank you, and sorry for my english.

I am using ESP32 CAM module for a line follower robot. And, I am trying to create a webserver with 3 submit push buttons. But for now, I just observe the input on serial port and work with only one submit bar. These push buttons specifies the PWM value of motors and some constants. Here is my code:

I am trying to do something with ESPAsyncWebServer library. I have a class in ServerManager.h called MyServerManager. When I compile the code I get this error. What am I doing wrong? How can I fix it?

25:67 is the bold word "this"
