Blur | apply blur/vibrant effect | iOS library

It is not infrequent that I need to access the element of a component, in vue. For instance here in element-plus, to make sure that the focus is removed:

I have multiple variables like so

I'm a Vue developer that's trying to do a React App.

I'm trying to wrap CodeMirror in a React app and I'm running into some troubles. Not sure how to fix it.

I'm instantiating a CodeMirror editor and attaching some event handlers to it. Those handlers are like so: When you focus the editor, the isFocused variable becomes true. When you focus out of the editor, the isFocused variable becomes false. When you type in the editor you should do some action if the isFocused variable is true.

In the last handler, I need to access a reactive variable set with useState (isFocused). That variable is not reactive in the context of that function. It's read as the default value false.

The component looks something like this:

In the project, required, max-size-number, min-size-number parts work, but pattern, minlength, and maxlength parts dont work,

How can I correct this?

here is the related code part;

I tried the following code:

I have a raspberry pi 4 running a tomcat server hosting my website. Right now it's blank, and I wanted to do connection tests on it before starting to build it. I am doing this to keep costs minimal and to be able to do other things with it later. However, as you can see in this image, I thought this was the way to set it up, but I get a 522 every time I try to connect to it. (I have IP blurred as it is my home IP). But, when I connect to the IP address directly, even through another wifi network, the page loads. Cloudflare has worked in the past when I was hosting on Google Firebase for a little bit, but once I switched to the pi, it stopped.

Thanks in advance for help.

I was wondering if there's a way to run a task as I wait for a user's message or reaction. I plan on making a game command where a blurred image slowly gets less blurrier and the players have to be the first one to guess what the image is showing before it's completely visible, however the wait_for coroutine forces me to wait for a message which makes me unable to decrease the blur on the image until a player guesses what it is.

I am attempting to implement the following tutorial: https://www.youtube.com/watch?v=GJIXTm_MsbY

I create the Blur class as instructed:
