Forenote: Let’s just think this differently and disregard rules established by HTML5 and focusing only on JSX. JSX has exactly two ways of passing true, <MyComponent prop /> and <MyComponent prop={true} /> and exactly one way of passing false <MyComponent prop={false} />. I do agree this is an oddity distinguishing between HTML5 and JSX, but … Read more
Have you tried with Box component? You could do something like <Typography component=”div”>Normal text <Box fontWeight=”fontWeightMedium” display=’inline’>medium font weight text</Box> and some more normal text</Typography> Note that component=”div” prop on Typography wrapper is required as Box component cannot be nested under the Typography’s default p.

useState by default simply does one thing and one thing only, set the new state and cause a re-render of the function. It is asynchronous in nature so by default, methods running after it usually run. From your example, on a fresh load of the page, typing ‘s’ causes useState to change the state, but … Read more
I had the same position problem when I try to show react-beautiful-dnd inside react-modal and I found a solution by adding these CSS to draggable items. .draggable { top: auto !important; left: auto !important; }
I think useCallback is what you want to use so you can get the width and height when it changes. const [height, setHeight] = useState(null); const [width, setWidth] = useState(null); const div = useCallback(node => { if (node !== null) { setHeight(node.getBoundingClientRect().height); setWidth(node.getBoundingClientRect().width); } }, []); return ( <div ref={div}> … </div> )
Overriding the Content-Type request header is not allowed for no-cors requests. Change the mode to cors. (You won’t be able to read the response without doing that either).
There are multiple mistakes in your test. Passing component type instead of component instance to render // this is wrong, passing component type baseDom = render(cardComponent); // this is right, passing component instance created with JSX baseDom = render(<cardComponent />); Using mouseMove instead of mouseOver event Searching element by title and passing text instead of … Read more
To really understand which one to use, we need to understand what’s happening under the hood. Material UI uses emotion(, or whatever styling engine you chose manually), in order to style its components. On the surface, the following two might seem to be doing the same thing: <Box sx={{ height:’50px’, width:’25px’ }}/> <div style={{ height:’50px’, … Read more
The useEffect is not triggered because the App component is not re-rendered, nothing changed in that component (no state or props update). If you want the App component to re-render when the route change, you can use the withRouter HOC to inject route props, like this : import { Switch, Route, withRouter } from ‘react-router-dom’; … Read more
The error message received indicates that you should be importing the createRoot method from react-dom/client instead of from react-dom. To fix the issue, modify your import statement for createRoot to look like this : import { createRoot } from ‘react-dom/client’; So the modified code should be : import React from ‘react’; import { createRoot } … Read more
