Next 13 throwing error on tRPC client promise - javascript

I know Next 13 is only in beta, but recently I started experimenting with tRPC and Next's data fetching. I have a server component that queries projects.getAll from my tRPC server and puts them in a Component.
Server Error
Error: Objects are not valid as a React child (found: [object Promise]). If you meant to render a collection of children, use an array instead.
Code:
const fetchProjects = async () => {
const data = await trpcClient.projects.getAll.query();
return data;
};
const PortfolioSection = async () => {
const getAllData = await fetchProjects();
console.log(getAllData);
return (
<section id='portfolio' className='min-h-screen py-5'>
<h1 className='text-4xl font-semibold mb-5'>Portfolio</h1>
<div style={{
display: 'grid',
gridTemplateColumns: 'repeat(auto-fill, minmax(300px, 1fr))',
gridGap: '16px',
}}>
{
getAllData &&
getAllData?.data?.map(({attributes}: any, projIdx: any) => (
<div className='bg-white p-4' key={projIdx}>
<div className='w-full h-32 relative'>
<Image
className='object-cover'
src={env.NEXT_PUBLIC_STRAPI_URI + attributes.thumbnail.data.attributes.formats.small.url}
alt='Project thumbnail'
fill />
</div>
<div className='px-4 pt-2'>
<div className='flex gap-2 my-3'>
{(attributes.tags as string).split(',').map((tag, tagIdx) => (
<span
key={tagIdx}
className='rounded-full px-3 py-1 text-sm font-semibold text-gray-700'
style={{background: `#${tag.split('#')[1]}`}}>
{tag.split('#')[0]}
</span>
))}
</div>
<h2 className='text-xl font-semibold text-gray-800'>{attributes.title}</h2>
<p className='text-gray-700'>
{attributes.blog_post.data.attributes.short}
</p>
<div className='flex gap-2 my-3'>
{
attributes.links.split(', ').map((link: any, linkIdx: any) => {
const [type, href] = link.match(/(?<=\[).+(?=\))/)[0].split('](');
return <Link
key={linkIdx}
href={href}
className='bg-gray-200 px-3 py-1 text-sm font-semibold text-gray-700'
target='_blank'
data-hover>
{
(() => {
switch(type) {
case 'github':
return <LogoGithub />;
case 'website':
return <ContentView />;
default:
return <LinkIcon />;
}
})()
}
</Link>;
})
}
</div>
</div>
</div>
)) || <></>
}
</div>
</section>
);
};
The error message:
Server Error
Error: Objects are not valid as a React child (found: [object Promise]). If you meant to render a collection of children, use an array instead.
P.S. This example does work with the regular tRPC hooks

react-csv component not generating file

i am new to react-csv component and struggling to download the csv which this component should return back to the user. below is an extract of my code.
I double checked the data returned from my API. Its an array of objects.
Please can you help out?
export default function ProductsTableFooter({ ...props }) {
const [data, setData] = useState([]);
useEffect(() => {
handleDownloadCSV();
}, []);
const handleDownloadCSV = async () => {
try {
console.log('clicked')
const data = await axios.get(
`http://api.myapiaddress.local/csv/products?fornitore=10&utilizzo=0&stato=Liquido&nome=cor`,
);
const resData = Papa.parse(data.data, { header: true, dynamicTyping: true }).data;
setData(resData);
} catch (error) {
console.error(error);
}
};
return (
<div className="flex flex-row rounded px-2 py-1 mt-2 text-white mr-4 mb-8 " style={{ background: colors.tableHeaderColor }}>
<div className="flex flex-row justify-start items-center flex-1">
<div>
<RoundButton icon={<FaFileCsv size={23} />} onClick={handleDownloadCSV} />
<CSVLink
headers={["a", "b", "c", "d", "d", "e"]}
target="_blank"
filename={"prodotti"}
data={data}
/>
</div>
</div>
</div >
);
}
In react-csv docs https://www.npmjs.com/package/react-csv, I see that if setting target="_blank", they use component CSVDownload. Y can try it:
<CSVDownload data={csvData} target="_blank" />;

Component with array.map (data) not show in modal pop up

I have problem, Why the component not show, in modal i want to show many data.
I want to get data from api, and data show in modal when i click.
i create my code like this.
State
const [visible, setVisible] = useState(false);
const toggleVisible = () => {
setVisible(!visible);
};
const [app, setApp] = useState([])
useEffect(() => {
const getApps = async () => {
try {
const response = await
axios.get("http://192.168.20.2:3000/api/V1/application")
setApp(response.data)
} catch (error) {
console.log("Error cannot get api application")
}
}
if (visible) {
getApps()
}
}, [visible])
return value
return (
<div>
<div className="font-sans">
<Modal
open={visible}
onClickBackdrop={toggleVisible}
className="w-11/12 max-w-7xl space-y-10 px-24 pb-20"
>
<Modal.Header>
<div className="grid grid-cols-2">
<div className="grid col-span-1 place-content-start">
<h1 className="text-4xl font-bold">Smart</h1>
</div>
<div className="grid col-span-1 place-content-end">
<Form>
<Input className="rounded-full" bordered type="text" placeholder="Search" />
</Form>
</div>
</div>
</Modal.Header>
<Modal.Body className="space-y-10">
<div className="grid grid-cols-3">
{
app?.map(app => {
<ProductCard
title={app.title}
subTitle={app.subTitle}
/>
})
}
</div>
</Modal.Body>
</Modal>
</div>
</div>
);
but, the component still now show.
i'm use .map, but still now show that component.
thanks before.
Note :
Api : 200 ok
If you are writing it inside a map function, check whether you are returning the modal. return (<Modal></modal/>)
<div className="grid grid-cols-3">
{
apps && apps.map((apps)=>{
return <ProductCard
icon='Icon'
title={apps.title}
subTitle={apps.subTitle}
/>
})
}
or
<div className="grid grid-cols-3">
{
apps && apps.map((apps)=>(
<ProductCard
icon='Icon'
title={apps.title}
subTitle={apps.subTitle}
/>
))
}

Can't resolve `Objects are not valid as a React child` Error - reduce method as bad guy?

Rendering the below component returns
Objects are not valid as a React child
import moment from "moment";
const PayrollRuns = (props) => {
const runItems = props.payrollRuns.map((run) =>
<div key={run.id} className="flex justify-between p-2 text-lg">
<div>
{moment(run.month.period).format('YYYY MMMM')}:
Paid {run.payroll_run_items.length} talents
</div>
<div>
{run.payroll_run_items.reduce((acc, value) => {
return value.amount;
})}
</div>
</div>
);
return (
<div className="runs-wrapper bg-white rounded-xl h-full w-48 shadow-sx-shadow p-4 flex flex-col">
<h1 className="border-b-2 pb-4">Payroll Runs</h1>
<div className="grow overflow-auto p-4">{runItems}</div>
</div>
)
}
export default PayrollRuns
I could drill down the issue to this part:
<div>
{run.payroll_run_items.reduce((acc, value) => {
return value.amount;
})}
</div>
So does the error mean that the reduce method returns an object rather than a single value? If yes, how to fix this? And if not, what else might be the issue?
Looks like you're trying to get a single value by adding it from the payroll_run_items array.
You haven't specified a start value for the accumulator, nor are you collecting the value.amount anywhere.
Here's a simple example to achieve what you want:
const payroll_run_items = [{
amount: 34,
// Other properties
}, {
amount: 35,
// Other properties
}]
console.log(payroll_run_items.reduce((acc, value) => {
return value.amount + acc; // Add 'value.amount' to 'acc'
}, 0)) // Specify a start value

React page infinitely refreshes the page every second

I have built an invoice dashboard system using React. I have another version of the app that is built with React and I run into the same issue.
I have commented out all calls to my API, the useEffect(), and it still reloads the page every second. Any suggestions would be helpful.

You are calling fetchUserInvoices in setTimeout and in the response your are setting the data, might be the reason.

Load More Pagination using Prisma, Urql & React?

I am following this tutorial → https://blog.logrocket.com/pagination-in-graphql-with-prisma-the-right-way/
In the end, there is a Load More based pagination that looks like:
I tried implementing it like:
import React from 'react'
import { useQuery } from 'urql'
import { Card } from '../components/index'
import {
GET_ALL_ACQUISITIONS,
GET_ACQUISITIONS_BY_PRICE,
} from '../graphql/index'
export const AcquisitionList = ({
minPrice,
maxPrice,
undisclosed,
sortByDescPrice,
sortByAscStartupName,
}) => {
const [skip, setSkip] = React.useState(0)
const [result, reexecuteQuery] = useQuery({
query: GET_ACQUISITIONS_BY_PRICE,
variables: {
minPrice,
maxPrice,
undisclosed,
sortByDescPrice,
sortByAscStartupName,
skip,
take: 20,
},
})
const { data, fetching, error } = result
if (fetching) return <p className="mt-10 text-4xl text-center">Loading...</p>
if (error)
return (
<p className="mt-10 text-4xl text-center">Oh no... {error.message}</p>
)
return (
<>
<div className="flex flex-wrap justify-center mt-10">
{data.getAcquisitionsByPrice.map((startup, i) => {
return <Card key={i} startup={startup} index={i} />
})}
</div>
<div className="flex justify-center">
<button onClick={() => setSkip(skip + 20)}>Load More...</button>
</div>
</>
)
}
But I lose all the previous state when I click Load More... button. It also replaces the entire UI with Loading as my if (fetching) condition is on top of the display Cards.
How do I preserve the previous state while calling Prisma with the new query so I can show all the display Cards?
So the first time, I have 20 cards, 2nd time when I load it should have 40 cards & so on...
Currently, it only shows 20 cards at a time which is great if I had Previous & Next button but I want it to show it like Instagram with a click of a button.
Had to store the result in a separate local state and on every new query results, just had to add to it:
import React from 'react'
import { useQuery } from 'urql'
import { Card } from '../components/index'
import {
GET_ALL_ACQUISITIONS,
GET_ACQUISITIONS_BY_PRICE,
} from '../graphql/index'
const Template = ({ children }) => (
<p className="mt-10 text-4xl text-center">{children}</p>
)
export const AcquisitionList = ({
minPrice,
maxPrice,
undisclosed,
sortByDescPrice,
sortByAscStartupName,
}) => {
const [acq, setAcq] = React.useState([])
const [skip, setSkip] = React.useState(0)
const [result, reexecuteQuery] = useQuery({
query: GET_ACQUISITIONS_BY_PRICE,
variables: {
minPrice,
maxPrice,
undisclosed,
sortByDescPrice,
sortByAscStartupName,
skip,
take: 20,
},
})
const { data, fetching, error } = result
React.useEffect(() => {
setAcq([...acq, ...data])
}, [data])
if (fetching && !data) return <Template>Loading...</Template>
if (error && !data) return <Template>Oh no... {error.message}</Template>
return (
<>
{data.getAcquisitionsByPrice.length > 0 && (
<div className="flex flex-wrap justify-center mt-10">
{acq.length > 0 &&
acq.getAcquisitionsByPrice.map((startup, i) => {
return <Card key={i} startup={startup} index={i} />
})}
</div>
)}
{fetching && <Template>Loading...</Template>}
{error && <Template>Oh no... {error.message}</Template>}
{data.getAcquisitionsByPrice.length !== 0 && (
<div className="flex justify-center">
