I have a problem to use React BarcodeScannerComponent. How can I stop the scan process after return result? By console.log, it return correct result and keep scan, how can I remove focus on the component so it can stop scanning ?

There is my Component, Thanks

I'm working on a React website and learning about React Hooks. In the project below, header.tsx and home.tsx are both components inside App.tsx. I have a user state object; i.e. const [user, setUser] = useState(); that I load in all 3 files (is this wrong?).

When I log into userbase in home.tsx, the UI reflects the change - the conditional body in home.tsx reflects the fact that user went from undefined to defined and the log out button is shown.

Here's the problem: I want header.tsx to also reflect the change in user; i.e. I expect header.tsx to be "listening" for changes in user and reflecting them on the UI, but it doesn't happen.

Can anyone shed any light? I'm also unsure of the placement of the userbase.init() call.

For some background, this project is based off this tutorial. I modified it to add React Router.

I'm trying to get a React app running in Azure App Services and having difficulties getting environmental variables to work.

When running locally I'm using a .env.local file to load environmental variables (which isn't checked into git).

I'm using the react-webcam npm library and currently, the "capture image" button is located at the bottom of the screen as shown here. Capture button default position

What I want to do is to get that button to the bottom center of the capture window as I've shown here. Area the capture button needs to be added

This is my camera and button

I installed React with tailwind from this: https://github.com/altafino/react-webpack-5-tailwind-2

I want to make a bg color like above in the picture. But I get no background-color its white. But Why?

this picture above is from tailwind.com first or second content

i want to locate the pathname for the image that i want to use in the project but i can't find the image. I have tried giving like this '../images/logo.png', but it shows Module not found: Can't resolve './images/logo.png' in 'C:\Users\55590i5 D'\Desktop\react-website-v2-master\src\components'

the file i.e. logo.png to access is inside public->images->logo.png and i want to import it inside src->components->navbar.js.

I'm having an issue with defining image path in react application and it's getting frustrating so I'm seeking help from the pros. I'm moving my images folder back and forth between public and src. When background:url(path) works, img src="path" doesn't work and vice-versa. I get this error "Error: Can't resolve 'images/img-2.jpg' in '/Applications/MAMP/htdocs/react-web/src'". If I move the images folder to src, it works but the background:url(path) does not load image. I have the project in https://github.com/miraj977/react-project/. Another issue is github pages; I have setup this project in gh-pages (https://miraj977.github.io/react-project/) but it only loads up to nav and stops. Doesn't load body. Also, I have set homepage in package.json "https://miraj977.github.io/react-project/" but whenever I click the logo which should redirect to homepage, it redirects to "https://miraj977.github.io/". I have shared the link to the github project for you to review the code. It's getting quite frustrating now. Please guide me on the right way to solve these issues. Your time is highly appreciated. Thank you in advance.

Okay, I thought I was crazy because I repeatedly failed at this, but I thought, maybe something is happening with the html that I don't understand.

I have been trying to scrape the 'articles' from cnn.com.

But no matter which way I tried soup.find_all('articles'), or soup.find('body').div('div')...etc with class tags, id, etc. FAIL.

I found this reference: Webscraping from React web application after componentDidMount.

I suspect injection in html is why I am having issues.

I know 0 about injection other than 'html injection attacks' from cyber security reading.

I want the articles, but I am assuming I will need to use a tactic similar to the other stack overflow question link above. I do not know how. Links to help documents or specifically cnn scraping would be appreciated.

Or if someone knows how I could get the 'full data' of the html body element, so that I could do some rearranging in my early code of this definition and then just reassign body.
