Hi @florent. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
I'm sorry, but the provided knowledge sources do not contain information on how to refresh data periodically in Refine. However, you can consider using a state management library or React's built-in hooks to manage state and trigger re-renders when your data changes.
For more detailed information, you can refer to the official Refine documentation (https://refine.dev/docs/getting-started/introduction).

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@kapa.ai
Can I query the data again using interval here?
Let me check the knowledge base for you. One moment! :books:
----------------------
The
getServerSideProps
function in Next.js is a server-side rendering function that runs at build time in production. It won't be able to set an interval to fetch data periodically because it's not running in the browser.
If you want to fetch data periodically, you should do it on the client-side, in a React component, using hooks like useEffect
. However, please note that this is not a recommended practice as it can lead to unnecessary requests and load on your server.
Instead, consider using a real-time data fetching library or use a state management library like React Query or SWR that supports background updates and caching.
For more information, you can refer to the Refine documentation (https://refine.dev/docs/getting-started/introduction) and the React Query guide (https://refine.dev/blog/react-query-guide).

Can I learn to SWR?
Let me check the knowledge base for you. One moment! :books:
----------------------
Yes, you can definitely learn to use SWR. It's a powerful client-side data fetching library used in modern web applications. It's particularly useful in React-based applications and comes with features like automatic revalidation, focus tracking, and error retries.
Here are some steps to get started with SWR:
1. Understand the basics of JavaScript and React, as SWR is a library for use with React and its frameworks. Make sure you have Node (https://nodejs.org/) installed on your computer.
2. Create a new React project with
create-react-app
:
or with Yarn:
3. Install the necessary packages for your application. In this case, you would need styled-components
and swr
:
or with Yarn:
4. Start learning how to fetch data with SWR and compare it with other data fetching methods like the native 'Fetch() API' or Axios.
5. Explore additional features of SWR like TypeScript support and developer tools for debugging and writing your code more efficiently.
You can find more detailed information and a step-by-step guide in this blog post (https://refine.dev/blog/data-fetching-next-js-useswr).

How to apply useSWR in this code?
@kapa.ai export default function PointList() {
type PointDetail = IPointDetailItem[] | ''
const [pointDetail, setPointDetail] = useState<PointDetail>('')
const [open, setOpen] = React.useState(false)
const [startValue, setStartValue] = React.useState<Dayjs | null>(null)
const [endValue, setEndValue] = React.useState<Dayjs | null>(null)
const handleClose = () => setOpen(false)
const handleOpen = (pointDetail: PointDetail) => {
setPointDetail(pointDetail)
setOpen(true)
}
const { dataGridProps, search, filters } = useDataGrid<BaseRecord, HttpError, IPointsFilterVariables>({
pagination: {
mode: 'server',
},
initialPageSize: 10,
onSearch: (params) => {
const filters: CrudFilters = []
const { q, points } = params
filters.push({
field: 'q',
operator: 'eq',
value: q !== '' ? q : undefined,
})
filters.push({
field: 'points',
operator: 'eq',
value: q !== '' ? q : undefined,
})
filters.push(
{
field: 'order_date',
operator: 'gte',
value: startValue ? dayjs(startValue).format('YYYY-MM-DD 00:00:00') : undefined,
},
{
field: 'order_date',

How to apply useSWR in this code?
Let me check the knowledge base for you. One moment! :books:
----------------------
To apply
useSWR
in your code, you would need to replace the data fetching logic with a useSWR
hook. However, the provided code and knowledge sources do not contain enough information to provide a specific example of how to replace your existing data fetching logic with useSWR
.
In general, you would use useSWR
like this:
In this example, '/api/data'
is the key for your data (usually the API endpoint), and fetcher
is a function that returns a Promise with your data. useSWR
will ensure that your component re-renders when the data changes.
For more detailed information on how to use useSWR
, you can refer to the SWR documentation (https://swr.vercel.app/docs/getting-started).

@kapa.ai how to writing a fetcher?
Let me check the knowledge base for you. One moment! :books:
----------------------
In your code, you've already written a fetcher function. The fetcher function is a function that fetches data from a given URL and returns a Promise that resolves with the data. Here's how you've defined it:
This fetcher uses the Fetch API to get data from the provided URL, and then it converts the response to JSON.
You're using this fetcher with
useSWR
like this:
In this line, useSWR
is called with two arguments: the key ('/api/data'
) and the fetcher function. The key is a unique identifier for the data (usually the API endpoint), and the fetcher function is responsible for getting the data.
If you want to use the data fetched in getServerSideProps
as the initial data for your SWR hook, you can pass it as initialData
in the options object:
In this case, props.points
should be the data fetched in getServerSideProps
.
For more detailed information on how to use useSWR
, you can refer to the SWR documentation (https://swr.vercel.app/docs/getting-started).

@kapa.ai
I fix this code
but return error this.
"No overload matches this call.
The last overload gave the following error.
Object literal may only specify known properties, and 'initialData' does not exist in type 'SWRConfiguration<any, any, BareFetcher<any>>'.ts(2769)
index.d.ts(200, 5): The last overload is declared here."
