I have successfully connected my custom server using Node.js and Express.js with Next.js. I'm trying to fetch a car by its id whenever I click it among other cars, so I can have that particular car only. But I keep getting an error saying params is undefined even though I get the id at the back of my link whenever I click on the single car in the browser. I've tried fetching the data using thunder client and everything works fine. I believe something is wrong with my frontend logic.
This is where I'm trying to fetch the data with the id

currently i am using fakestoreapi, here i am passing category parameter to fetch data from api.
const res = await fetch(`https://fakestoreapi.com/products/${category}`)
and displaying products from fetched data
{products.map((product, index) => (
<div key={product.id} className="w-full max-w-sm text-black rounded-lg shadow-md bg-white justify-bitween cursor-pointer ">

but now i do not want to display all product of that category how to do that?
how to show selective or remove unwanted product details fetched from that id?
Fakestore API can receive a limit query parameter :
fetch('https://fakestoreapi.com/products/category/jewelery?limit=2')
.then(res=>res.json())
.then(json=>console.log(json))
You can also use limit(Number) and sort(asc|desc) as a query string to get your ideal results

How do I hide my page "section" when I click on a button. and show it another button is clicked
Here's my code
import './App.css';
import Typed from 'react-typed';
import { useState, useEffect } from 'react';
function App() {
return (
<div className='text-white'>

</div>
<div id='ino' className='info max-w-[800px] mt-[-96px] w-full h-screen mx-auto text-center flex flex-col justify-center'>
<h1>Hello</h1>
</div>
</div>
);
}
how do i make the onClick event work it out?
Just set a state let's call it for example hide and set default value false, and on the button click turn it to true.
And you can conditionally hide the button section and show the info section.
import "./App.css";
import Typed from "react-typed";
import { useState, useEffect } from "react";
function App() {
const [hide, setHide] = useState(false);
return (
<div className="text-white">
{!hide ? (
<div
id="index"
className="index max-w-[800px] mt-[-96px] w-full h-screen mx-auto text-center flex flex-col justify-center"
>
<div className="flex justify-center items-center">
<h1 className="md:text-7xl sm:text-6xl text-4xl font-bold md:py-6">
Roll
</h1>
<Typed
className="md:text-7xl sm:text-6xl text-4xl font-bold md:py-6 text-gray-400"
strings={["simply", "design"]}
typeSpeed={70}
backSpeed={100}
loop
/>
</div>
<p className="md:text-3xl sm:text-2xl text-xl font-bold py-4 ">
best <a className="underline text-gray-300">design</a> and{" "}
<a className="underline text-gray-300">simplistic.</a>
</p>
<button
className="bg-white text-black w-[200px] transition-[0.5s] rounded-lg font-bold my-6 mx-auto py-3 ring-2 ring-gray-300 hover:bg-slate-300 hover:shadow-xl hover:shadow-white hover:scale-110"
onClick={() => setHide(true)}
>
Create
</button>
//clicking this button will show the div below which has the id of
info and hide this current div
</div>
) : (
<div
id="info"
className="info max-w-[800px] mt-[-96px] w-full h-screen mx-auto text-center flex flex-col justify-center"
>
<h1>Hello</h1>
</div>
)}
<div
id="ino"
className="info max-w-[800px] mt-[-96px] w-full h-screen mx-auto text-center flex flex-col justify-center"
>
<h1>Hello</h1>
</div>
</div>
);
}
You should use useState() react hook.
For example:
import './App.css';
function App() {
const [visible, setVisible] = useState(true);
return (
<div className='text-white' style={{display: visible ? 'block' : 'none'}}>
<div>
<!--first part-->
<div className='flex justify-center items-center'>
<h1 className='md:text-7xl sm:text-6xl text-4xl font-bold md:py-6'>Web</h1>
<!--stuff here-->
</div>
<p>stuff here</p>
<button onClick={() => setVisible(!visible)}>Create</button>
<!--when i click on the button it will hide the first part(section) and show the second part -->
</div>
<!--first part end -->
<div>
<!--second part -->
<h1>Hello</h1>
</div>
</div>
);
You could check more details how to use useState() hook here https://reactjs.org/docs/hooks-state.html
I am using react and globalContext to add items to a cart page and this adds the product to the array stored in localStorage and looks like this.
0: {id: "9", title: "Apple Watch SE 40mm (GPS) - Space Grey Aluminium Case with Midnight Sport Band",…}
id: "9"
price: 249.99
quantity: 1
src: "/static/media/se.0ca02982636517aed223.png"
title: "Apple Watch SE 40mm (GPS) - Space Grey Aluminium Case with Midnight Sport Band"
I have a quantity selector on the page for every item added to the basket which displays the quantity how do i make it so when that quantity is changed the price alters too?

import { faChevronLeft, faClose, faPlus, faMinus } from '#fortawesome/free-solid-svg-icons'

let cartArray = localStorage.getItem("basket");
cartArray = JSON.parse(cartArray);
const total = cartArray.reduce((prev, cur) => (cur.price * cur.quantity) + prev, 0);
console.log(total)
const [quantity, setQuantity] = useState(0);
const handleReduceQuantity = () => {
if (quantity === 0) return;
setQuantity((prev) => prev - 1);
};
const handleIncreaseQuantity = () => {
setQuantity((prev) => prev + 1);

At the moment the quantity selector is just a counter and doesn't change the quantity of the item in localStorage and therefore doesn't change the total price.
const items = [
{
id: "9",
price: 200,
quantity: 1,
src: "/static/media/se.0ca02982636517aed223.png",
title: "Apple Watch SE 40mm (GPS) - Space Grey Aluminium Case with Midnight Sport Band",
},
{
id: "3",
price: 300,
quantity: 1,
src: "/static/media/se.0ca02982636517aed223.png",
title: "Apple Watch SE 40mm (GPS) - Space Grey Aluminium Case with Midnight Sport Band",
}
];
const calculateTotal = (items) => {
const total = items.reduce((acc, curr) => (curr.price * curr.quantity) + acc, 0);
console.log(total);
}
const handleQuantityUpdate = (itemId, operation) => {
const newItems = items.map((i) => {
if(i.id === itemId){
return {...i, quantity: operation === 'increase' ? i.quantity + 1 : i.quantity - 1};
}
return {...i};
});
//need to store into localstorage at this point
console.log(newItems);
calculateTotal(newItems);
}
handleQuantityUpdate("9", 'increase');
handleQuantityUpdate("3", "decrease");
I'm using react-hook-form, and I'm wondering if it's possible to create a component that is passing the form errors using react-hook-form.
I have the following component
import { useForm } from "react-hook-form";
import { XIcon } from "#heroicons/react/outline";
export default function ErrorsPopup() {
const {
formState: { errors },
} = useForm({
criteriaMode: "all",
});
return (
<>
{Object.keys(errors).length > 0 && (
<div className="mt-6 text-white bg-red-600 border-4 border-red-700 alert-start">
<div className="flex justify-between items-center bg-red-700 py-2 px-4">
<div>
<p>The following errors have occurred:</p>
</div>
<div className="cursor-pointer">
<XIcon className="h-6 w-6 text-white alert-close" />
</div>
</div>
<div className="py-2 px-4">
<div className="flex flex-col gap-2">
{Object.entries(errors).map(([index, error]) => (
<div className="flex flex-col gap-y-6 sm:gap-x-8" key={index}>
<p>• {error.message}</p>
</div>
))}
</div>
</div>
</div>
)}
</>
);
}
and I have added this to the following page

So I'm trying to create a component for all forms where I can simply just show any errors to keep the code DRY, but the component is not showing up.
Sure I'm missing something silly but I'm new to react so any help would be create.
You've have to use FormProvider in your Login component and useFormContext in your ErrorPopup

I believe you need to use useFormContext instead of useForm in your ErrorsPopup component

You can :
Use // eslint-disable-next-line react-hooks/exhaustive-deps on top of the line causing the error
Disable this eslint rule in .eslintrc.json
Simply include the missing variable in the useEffect dependency array ([session, postImage])
