I am using semantic-ui react to render a table of data. My requirement is that when the page is on mobile view, I hide certain columns. I tried using className="mobile hidden" on the Table.Cell element but this doesn't seem to work at all.
Then I tried using the Responsive component like below but I am getting an error. Am I missing something here? Unable to find anyone else having this issue ...
<Responsive as={Table.Cell} minWidth={Responsive.onlyMobile.minWidth}>
{record.datapoint}
</Responsive>
I get this error in the console when resizing the window...
index.js:2177 Warning: Can only update a mounted or mounting component. This usually means you called setState, replaceState, or forceUpdate on an unmounted component. This is a no-op.
Please check the code for the Responsive component.
In fact, this is bug :( I've created PR that will solve described issue, see Semantic-Org/Semantic-UI-React#2421.
Code that you provided doesn't reproduce problem, the issue will be never occured with provided example. However, it exists :) The core problem is the unmount of Responsive component when it will be done by parent and setState() will be called on unmouted component. An example on codesandbox reproduces problem.

I was building a scheduling app with react-big-calendar and I have noticed from React v17 onwards the resizable does not work because of the way react handles event changing.
this is the issue: https://github.com/jquense/react-big-calendar/issues/1785
I have seen in the comments that someone fixed this issue and made a pull request: https://github.com/jquense/react-big-calendar/pull/1857
My problem is that it is still not working, the resizable handles does not show up on the big calendar. I made sure I am using the latest version 0.33.6 and also tried to figure out where the user did the changes to events to fix the issue so that I can modify the package, but I noticed they both are completely different files, I wasn't able to find the event handlers in my node_modules/react-big-calendar so that I can make edits. So how do I fix this error? I cannot revert back to reactv16 because I must use v17 in my project.
Thanks in Advance! :)
Here's what my calendar looks like:
<DragAndDropCalendar
selectable
resizable
onEventDrop={onEventDrop}
onEventResize={resizeEvent}
localizer={localizer}
events={events}
onSelectSlot={handleSelect}
defaultView="week"
defaultDate={new Date()}
timeslots={2}
step={15}
popup
tooltipAccessor={(e) => e.title}
/>
</div>
I’m new in coding and i couldn’t get how to fix the issue after i googled many times. The issue is i have a layout component which contains 4 different components. When i call a function in a function component it affects the others and the others re-render. Re-render is fine tho however my images are flickering on mobile browser. I would like to remove the flickering of the image loading. I’ve tried using React.memo() and useCallBack() but both of them didn’t work for me. I hope I made myself clear , thanks in advance
This is my app https://stackblitz.com/github/mithatercann/qrmenu
You are using what's its called "Prop Drilling". The better solution for your current problem is to implement some state management in your app, they are many third libraries for that, but for this instance and if your app is small you can use React Context API. If you're going to build big apps then I recommend implementing Redux.
I need to debug some props that are being used in my React application. However, if I try to inspect certain components, they appear as "Loading..." instead of the normal props list:
However, I know that these components have already rendered as I can see them in the DOM. Also, it stays like this perpetually, so it obviously isn't actually loading anything.
I'm using React DevTools 4.2.1-3816ae7c3 and React 16.12.0
I was having the same issue with Ubuntu and after reinstalling the extension. Close the chrome app and reopen it, then it solved it for me.
Is is possible to make Navigator component behave similar to NavigatorIOS component ? If so which I think is certainly possible, what is the relevant code to do so ?
What counts as behaving similar to NavigatorIOS? You can try checking out react-native-router and see if it's something that would help you. If you do want to try it, you'd have to go to this PR and use those fixes, because the owner of the module hasn't updated in a while.
