I've built my website in Next.js, deployed statically via Netlify. Whenever I load it in a new tab, I get a white flash where the SVG logos are visible but nothing else, before the rest of the content loads in. I don't think this is a Flash Of Unstyled Content but it has a similar effect. I'm experiencing on desktop Chrome, Safari and Firefox, but doesn't seen to be happening on mobile. I've been trouble shooting for hours and am no closer to solving. Here's the repo if anyone wants to have a look. Any insights greatly appreciated.
Quoting directly from styled-components' docs:
Basically you need to add a custom pages/_document.js (if you don't
have one). Then copy the logic for styled-components to inject the
server side rendered styles into the .
Refer to our example in the Next.js repo for an up-to-date usage
example.
When using styled-components with Next.js you need to do a little magic in the _document.js. There is a with-styled-components example in the Next.js' repository. Please see here: https://github.com/vercel/next.js/blob/canary/examples/with-styled-components/pages/_document.js

I've recently updated my react app to the latest version 18, but since doing that the html in localhost disappears after a few seconds. When I go to dev tools and look at the in 'Elements', it's empty but all of the content is still on the page, I just can't interact with it (click links or buttons, etc.).
Does anyone know what is causing this as I need to know before I push my code to production, as I'm not sure if this is a development environment issue.
I'm more than happy to post screenshots of my code, but I don't even know which screenshots would be helpful/relevant. Let me know if you need any. Thanks
Is there any way to hide react source codes in server side browser(Like google chrome, Firefox, Microsoft Edge). I am seriously stucked with this, as i am trying to develop a react application but it shows all of my source code in the browsers. Any help will be highly appreciated. Thanks.
React is a Frontend library. You are asking how to hide html, css and js source code in browser. If you want to hide your logic from web browser then use a backend. Easiest way is to use Next.j. All the code you write in getServerSideProps() will not be shipped to the browser and only runs on the server. All pages will render server side . This way you can ship only html, css and js to browser without your app logic
You can't hide it necessary, perhaps you could obfuscate it a bit
Here is an article that goes more in-depth: https://code-boxx.com/hide-javascript-code-from-client/
I've got a really weird bug in a create-react-app application. Onsenui is used as a css framework. But when I try to run the app, either in production or on localhost on a chromium based browser, the framework doesn't get loaded. Both css and js aren't loaded. (Only the OnsenUI ones, other css and js is loaded correclty) I then have to refresh the page multiple times to make it work. It loads correctly on Firefox and Safari.
The problem persists on both my MacBook and my Windows PC. I'm not the original creator of the repo and it's already a few years old. I have however updated onsenui, react-onsenui, react to the newest version.
Unfortunately, I can't share the link to the page.
So, in the end, it's been all because of a pop-up blocking extension I had installed. I can't believe I haven't thought of it and I've been refreshing the page multiple times/had to use other browsers just because of this.
So if anyone ever sees this is the future with a similar problem, double check all your active extensions.
I'm creating a gallery of images in ReactJs. There are a lot of examples online, but i didn't find anything that is perfectly responsive on desktop browsers and also completely mobile friendly.
In particular, when an image is opened on the mobile browser, i need to be able to zoom the photo with a double tap, and close the photo when i drag it to the bottom
I already tried all the principal solution that i found online.
For example, i tried all of these https://reactjsexample.com/tag/lightbox/
and much much more.
I also tried different approaches like CSS rules, Viewport rules, create a simple zoomable html div, etc... But nothing worked.
Basically, what i what to achieve is exactly something like this: https://www.lucapetruzzi.com/gallery/1
Created thanks to this library: https://photoswipe.com/ that unfortunately i can't use in React.
(I also tried the react-photoswipe and react-photoswipe-2 libraries but it seems not maintained and not working with new versions of React)
Thank you for any help
So for previous comments, I wrote a snippet for you, check here
Here are the mainly steps:
use npm install photoswipe so DON'T need to include builded js but NEED to include css in index.html (or you can import in App.css)
write the markup in js component
init it by click button or in useEffect
I use create-react-app 16.["react": "^16.8.4", "react-scripts": "^2.1.8"]
I read the blog on profiling react performance by Ben Schwarz using Chrome Dev tools:
https://building.calibreapp.com/debugging-react-performance-with-react-16-and-chrome-devtools-c90698a522ad
He recommends to export your JS with source-maps.
When he does a performance trace, and clicks on a given react component in the User Timing section, specific component information shows in the Bottum-Up section with ** blue links to the source code** on the right hand side. This links don`t show, when I click on React components. When I click on components like for instance Evaluate Script, the blue links on the right hand side show.
Isn`t source mapping supposed to work "out-of-the-box" with create-react-app 16 in development.
I want to source-map only in development using Chrome Dev tools. Source mapping is activated in the Chrome Browser. What am I missing?
Thx in advance
P.S.:Since I haven`t got 10 reputation points I´m not suppose to use screenshots, which in this case made things not quite easy. I hope I managed to explain my problem sufficiently, though.
The Source Files for Debugging will be available under your localhost:3000 in the Chrome devtools.
We always tend to search under webpack://
Changes have been made to the newer versions I beleive

Could you check the file
node_modules/react-scripts/config/webpack.config.js
Search there for the sourceMap and sourceMaps, and see if that is ok for you.
You can copy that file like "_original", and then set
sourceMaps: true,
in all ocurrences. After that, completely stop the app, and then start it again.
Is that working now?
To verify which sourceMap is working or not, add the sources to workspaces and check for the green dot:
