QUESTION
I'm trying to achieve a behaviour, when merely changed items of the list are being updated and rerendered with new data.
I wrote a component which is being updated when timer is off:

All is pretty straight. When I was passing a function as a child, it was constantly being created over and over again. So the solution was to move child function definition out of render method like so:
QUESTION
I'm experimenting with the windowing technique in Next.js with Antd, and I made this simple app that has this index.tsx page:
...ANSWER
Answered 2022-Mar-09 at 06:08I finally found a solution after much agony.
Apparently, Nextjs wraps the entire layout with a div with id __next
. That's the outer-most container of the entire page, and its height is not set, so since the content of FixedSizeList
is positioned such that it's outside of the regular page flow, the __next
div gets a height of 0.
I don't know if there is any better solution, but I simply added this little style in the globals.css file:
QUESTION
I am using react-table
with react-window-infinite-loader
and react-window
for infinite scrolling. Initially the table has 20 items(data) on fetch from API.
After adding a new data into my table it will successfully update(thru redux) and the data will be 21 now and rows with 21 too. But after scrolling and scrolling the data still has an extra 1 data(ex. 21 > 41 etc. every scroll adds 20 items fetching from API) but the rows is different in length after a few scroll in the table(ex. 21 > 40) 1 row was automatically or suspiciously removed see Row(index) 21 was removed image(without any actions made just by scrolling) index 21 was removed.
This will occur an error because the last index of the table now will be 40 and the length of the rows only
40 the below snippet of code will be undefined
ANSWER
Answered 2022-Mar-07 at 06:38I got the solution, the problem is duplicating the data when I fetch data from API every scroll. What I did is remove the duplicate data(i.e using uniqBy function from lodash module)

QUESTION
ANSWER
Answered 2021-Oct-07 at 20:55Move Row
outside of App
. When a component rerenders all of its variables are redeclared, which means new values except where they have been memoised by a relevant hook e.g. useMemo
, useCallback
. You are getting a new value for Row
on every render.
React.memo
is not a memoisation hook, it is a higher-order component which controls when new props should be passed to a specified component. It should be declared outside of the React render cycle (as should all components) in order to function correctly.
QUESTION
import { FixedSizeList as List } from 'react-window'
import AutoSizer from 'react-virtualized-auto-sizer'
const TrackTable = ({ tracks }) => {
const Row = ({ index, style }) => (
Row {index}
)
const AllRows = () => {
const arr = [
{ code: '12H', id: '1' },
{ code: '4gf', id: '2' },
]
return arr.map((i, index) => {
return {i.code}
})
}
return (
{({ height, width }) => (
{AllRows()}
)}
)
}
...ANSWER
Answered 2021-Sep-16 at 11:50You call AllRows
without proprty, in this case tracks
is undefined
==> you will have the error tracks.map is not a function
to avoid that, call AllRows
with an array :

I am putting together an infinite scrolling list using react-window

...ANSWER
Answered 2021-Aug-10 at 15:33The main issue is that you shouldn't be using Menu
for this. Menu
assumes that it has MenuItem
children and has accessibility functionality geared towards that assumption. The behavior you are seeing is caused by the functionality that tries to navigate to menu items by typing the character that the menu item's text starts with. In your case, it is finding the text of the label "Search", and then it is moving focus to that "menu item" (which is why you then get a focus outline on the div containing your TextField
). If you change the label to "Type Here", you'll find the "s" works, but "t" doesn't.
My recommendation would be to use Popover directly (the lower-level component which Menu
delegates to for the main functionality you are using from it). Another option would be to use the Autocomplete component since you seem to be trying to use Menu
and the pop-up TextField
to do your own custom version of what the Autocomplete
component provides.
QUESTION
I have follow a couple of examples using react-table and react-window so far so good, but I need the table to have select boxes to select individual or grouped rows as well as a radio-like button to be able to toggle information for a row, I manage to implement this but when I scroll up or down the selected radio button looses its selected state, as shown below
As you can see when I select a row its ID is displayed below the table but when I scroll and move the row away from the view the radio button looses its checked state.
I have an example of the code here

QUESTION
In my react project I am using react-window
package to render nested lists. Each parent FixedSizeList
row renders a component which uses another FixedSizeList
. Parent List doesn't have more than 14 rows at the moment. But the child List may contain upto 2000 rows. Now my problem is, when I try to scroll through the parent List, all the child list items in the viewport seem to re rendering. This is a little bit problematic for me because in my child list item I am using d3js
to draw bar chart with transition effect. So these unnecessary re rendering is giving a overall weird UI. Can anyone help me how can I stop these unnecessary renders.
Here is codesandbox link to a very simple example of my problem. Please open the console log. After initial load the topmost log should be like this: initial console log.
Then if you clear the console and scroll the parent list, you will see log like this: console log after parent scrolling. Here you can see that the child list items of child list 0 is re rendering which is not needed for me.
Can anyone give me a solution that can stop these re rendering?
*P.S. I am not using memo since every row is updating the dom on its own.
Edit
I think this problem would solve if the parent list would stop propagating scroll event to child. I tried to add event.stopPropagation()
and event.stopImmediatePropagation()
in the parent list row but the output was the same as earlier.
ANSWER
Answered 2021-Aug-05 at 11:54We can use memo
to get rid of components being re-rendered unnecessarily for same set of props
. And use useCallback
to prevent re-creation of a function and thus secure child components being re-rendered. Applying those, we can get this solution:
