Adding items to cart in react js

In reactjs, what code would I have to write in my two components(homepage.js with an add-to-cart button and a checkout page with a clear cart button? This is my Homepage.js where I fetch the items from my backend server, map, and display them on the page.
function Home() {
const [data, setData] = useState([]);
useEffect(() => {
// auto-login
fetch("/coffees").then((res) => {
if (res.ok) {
res.json().then((data) => setData(data))
}
});
}, [])
console.log(data)
return (
<>
<div className="box">
<div className="projo">
<h2 >Welcome to Coffee-cafe</h2>
</div>
<div className="projects">
{data.map((data) =>{
return(
<div className="card">
<img className="avatar" src={data.coffee_image} alt="coffee"></img>
<div className="card-content">
<h4><b>{data.coffee_name}</b></h4>
<p id="desc">{data.description}</p>
<p className="price">{data.price}</p>
{/* <p>{data.category}</p> */}
<button onClick={() => ({})} className="btn1" id="btn1">Add to Cart</button>
</div>
</div>
)
})}
</div>
</div>
</>
)
}
export default Home;
For the Checkout.js, this is what I have currently.
function Checkout() {
return (
<>
<div className="section">
<div className="photo">
<img className="dp" src={image1} alt="coffee"></img>
<div className="info">
<h3>Coffee:</h3>
<p>Price:</p>
<p>Category:</p>
<div className="check-out-btn">
{/* <button className="add">AddToCart</button> */}
<button className="delete">ClearCart</button>
</div>
</div>
</div>
</div>
take a look for a global states like redux , context,or zustand
for my recommendation, I suggest zustand is less code than context and redux and short learning curve
carts =[]
setItemToCart(item){
const isExist = carts.find(c => c.id ===item.id)
if(isExit){
const qty = isExit.qty+item.qty
const newItem= {...item,qty}
// push is not recommended to use because it mutates state
carts.push(newItem)
}else{
carts.push(item)
}
}

Pagination with Firebase v9 and React not working

I'm trying to build a page that paginates all the data from a collection, however I can't seem to figure out how to do it and I haven't found anyone who's done it either.
I've tried to get the documentList.length, but that also isn't working.
function Sessions() {
const location= useLocation();
const user= location.state.user;
const [sesList, setSesList] = useState([]);
const subRef=collection(db, 'Users',user,'Sessions');
let q = query(subRef,orderBy('time','desc'),limit(5));
const DocumentSnapshot=getDocs(q);
const last= DocumentSnapshot[DocumentSnapshot.length-1]
const next=()=>{
return q=query(subRef,orderBy('time','desc'), startAfter(last), limit(5))
}
const prev=(first)=>{
return q=query(subRef, orderBy('time','desc'), endBefore(first['time','desc']), limitToLast(5))
}
useEffect(() => { //loads all the tenants
onSnapshot(q, (snapshot) => {
setSesList(
snapshot.docs.map((doc) => ({ ...doc.data(), id: doc.id }))
);
});
}, []);
return (
<div className='Sessions'>
<Sidebar className='nav'
L1={<Link to='/Dashboard' state={{user:user}}>Dashboard</Link>}
L2={<Link to='/Sessions' state={{user:user}}>Sessions</Link>}/>
<div className="bod">
<div className="startCard1">
<h1>Sessions</h1>
</div>
<div className="Recent">
<h1>Your Sessions:</h1>
<div className="recSes">
{sesList.map((REC)=>{
return(
<div className="rowCard">
<div className="rowCardTitle">
<h3> Subject: {REC.subject}</h3>
</div>
<div className="WTime">
<h3>Work Minutes: {REC.WorkTime}</h3>
</div>
<div className="BTime">
<h3> Break Minutes: {REC.BreakTime}</h3>
</div>
<div className="Atime">
<h3>Date: {REC.time}</h3>
</div>
</div>
)
})}
</div>
</div>
<div className="buttoninlin">
<button className='Gobtn1'>Previous </button>
<button className='Gobtn1' onClick={next}>Next</button>
</div>
</div>
</div>
)
}
export default Sessions
expected result: next button shows next documents, back button shows previous documents

why link doesn't work when I use getStaticProps?

I'm new in next js and I'm working on project using NextJS. I have some lots in my items page that shows lots currently(pagination/items.tsx) and I also have lotDetails page that I want it to show details of each lot using dynamic route(lotDetails\id\index.tsx).
This is the folder structure:
Now when I click the Link in Items.tsx I expect it to go to lotDetails page and pass the props, but nothing happens! (It stays on Items page!). here is Items.tsx:
import React from 'react'
import Link from "next/link"
const Items = ({currentItems}:{currentItems:any}) => {
console.log(currentItems)
// const ids=currentItems.map((el:any)=>el.id)
// const paths=ids.map((el:any)=>{params:{id:el.toString()}})
// console.log(paths)
return (
<>
<div className="container">
<div className="row">
{currentItems.map((el:any)=><div className="col-md-3 ">
//this should be linked to lotDetails page!
<Link href={{pathname:"../lotDetails/[id]",query:{id:JSON.stringify(el.id),title:el.title,image:el.image,description:el.description.toString(),rate:el.rating.rate,count:el.rating.count,price:el.price},}} as={`/lotDetails/${el.id.toString()}`}>
<div className="lot">
<div className="img-container">
<img src={el.image}/>
</div>
<div className="title">
{el.title}
</div>
<div className="price">
<span className="price-title">Price:</span>
<span>{el.price}</span>
</div>
</div>
</Link>
</div>)}
</div>
</div>
</>
)
}
export default Items;
I'm using getStaticProps and GetStaticPaths in lotDetails:
const LotDetails = (props:any) => {
const dispatch=useDispatch();
console.log(props)
const lotCount=1;
const addLots=()=>{
dispatch(AddCustomerLot({...props,lotCount:lotCount}))
}
return (
<>
<div className='container lot-details'>
<div className="row" >
<div className="col-md-6">
<div className="detail-container">
<div className="title-details"><h3>{props.title}</h3></div>
<div className="badge"><FontAwesomeIcon icon={faStar}/><span>{props.rate}</span></div>
<div className="inventory">
Inventory: <span className="count">{props.count}</span>
</div>
<div className="description-details">{props.description}</div>
<div className="price">Price: <span className="price-number">{props.price}$</span> </div>
<button className="btn btn-regist" onClick={addLots}>Add to shopping basket</button>
</div>
</div>
<div className="col-md-6"><img src={props.image} alt="" /></div>
</div>
</div>
</>
)
}
export const getStaticPaths:GetStaticPaths=async(context:any)=>{
const response= await axios.get("https://fakestoreapi.com/products")
const paths=response.data.map((el:any)=>({params:{id:el.id.toString()}}))
console.log(paths)
return{
paths,
fallback:'blocking'
}
}
export const getStaticProps:GetStaticProps=async(context:any)=>{
return{
props:
{
//recieve props
id:context.query.id,
title:context.query.title,
image:context.query.image,
description:context.query.description,
rate:context.query.rate,
count:context.query.count,
price:context.query.price
}
}
}
export default LotDetails;
when I deleted getStaticProps and getStaticPaths, the link worked! So I receive that link works perfectly and the problem is in getStaticProps and getStaticPaths. Of course I don't want to use getServerSideProps.
Update
According to julio's suggestion I changed pathName, and I also changed context.query to context.params.id:
Items:
<Link href={{pathname:`/lotDetails/${el.id}`,query:{id:JSON.stringify(el.id),title:el.title,image:el.image,description:el.description.toString(),rate:el.rating.rate,count:el.rating.count,price:el.price},}} as={`/lotDetails/${el.id.toString()}`}>
<div className="lot">
<div className="img-container">
<img src={el.image}/>
</div>
<div className="title">
{el.title}
</div>
<div className="price">
<span className="price-title">Price:</span>
<span>{el.price}</span>
</div>
</div>
</Link>
lotDetails:
return (
<>
<div className='container lot-details'>
<div className="row" >
<div className="col-md-6">
//I removed all section which used props and querys using comments
{/* <div className="detail-container">
<div className="title-details"><h3>{props.title}</h3></div>
<div className="badge"><FontAwesomeIcon icon={faStar}/><span>{props.rate}</span></div>
<div className="inventory">
Inventory: <span className="count">{props.count}</span>
</div>
<div className="description-details">{props.description}</div>
<div className="price">Price: <span className="price-number">{props.price}$</span> </div>
<button className="btn btn-regist" onClick={addLots}>Add to shopping basket</button>
</div> */}
</div>
{/* <div className="col-md-6"><img src={props.image} alt="" /></div> */}
</div>
</div>
</>
)
}
export const getStaticPaths:GetStaticPaths=async(context:any)=>{
const response= await axios.get("https://fakestoreapi.com/products")
const paths=response.data.map((el:any)=>({params:{id:el.id.toString()}}))
console.log(paths)
return{
paths,
fallback:'blocking'
}
}
export const getStaticProps:GetStaticProps=async(context:any)=>{
return{
props:
{
id:context.params.id,
// title:context.query.title,
// image:context.query.image,
// description:context.query.description,
// rate:context.query.rate,
// count:context.query.count,
// price:context.query.price
}
}
}
Finally, I solved problem in two steps:
1-I'm using google chrome browser, so I configured chrome and added my localhost port:
I used this link: chrome://inspect/, clicked configure button and added my localhost port(in my case localhost:3000)
2-I added this code to lotDetails page(the page which I used axios)
axios.defaults.httpsAgent=new https.Agent({
rejectUnauthorized:false,
})
don't forget to import:
import https from "https"
Now It's working.

How to display data from firebase single document using React?

Before this, I'm using Snapshot and try to map it. But it failed for a single document. After I read back the documentations from firebase. They recommend using this way for a single document. But I don't know how to make it readable on the site rather than console. I want to send data on the title and essay.
const { id } = useParams()
useEffect(() => {
db.collection("posts").doc(id).get().then(doc => {
const newData = doc.data();
console.log(newData);
});
}, []);
return (
<div className="log">
<article className="log-details">
<div className="author-pic clearfix">
<img src={profile} alt="" />
</div>
<div className="log-preview">
<div class="cover"></div>
<h2 className="title clearfix">title here</h2>
<div className="details ">
<img src={One} alt="" />
<p className="essay">essay here</p>
</div>
</div>
</article>
</div>
)
To display the post Data use useState and set the postData with setPostData(newData). Then you can read the postData values with {postData.title} and {postData.essay} in the return statement.
Dont forget to import useState with import React, { useState, useEffect } from "react".
const { id } = useParams()
const [postData, setPostData] = useState("");
useEffect(() => {
db.collection("posts").doc(id).get().then(doc => {
const newData = doc.data();
setPostData(newData);
console.log(newData);
});
}, []);
return (
<div className="log">
<article className="log-details">
<div className="author-pic clearfix">
<img src={profile} alt="" />
</div>
<div className="log-preview">
<div class="cover"></div>
<h2 className="title clearfix">{postData && postData.title}</h2>
<div className="details ">
<img src={One} alt="" />
<p className="essay">{postData && postData.essay}</p>
</div>
</div>
</article>
</div>
)

Button Click to Render Div

I want to click the button and render its corresponding div. Should I add the the div's info that I want to render to the state?
I'm sure there's a few different ways to solve this but I want to do it the React way and maybe as a function component?
Updated
export default function About(props) (
const [isHidden, setIsHidden] = useState(true);
const handleClick = () => {
setIsHidden(!isHidden);
};
return (
<div className="row justify-content-md-center">
<div className="col-auto">
<CustomButton onClick={handleClick}>Website Develpment</CustomButton>
</div>
<div className="col-auto">
<CustomButton onClick={handleClick}>Wordpress Develpment</CustomButton>
</div>
<div className="col-auto">
<CustomButton onClick={handleClick}>Ecommerce Development</CustomButton>
</div>
</div>
<div className="row">
<div className="col-md-4">column 1</div>
<div className="col-md-4">column 2</div>
<div className="col-md-4">column 3</div>
</div>
);
)
You can store an ID as a string state variable, and set that variable on button press.
Then use ConditionalRendering to only display the div with the matching ID.
const {useState} = React;
function About(props) {
const [visibleItem, setVisibleItem] = useState('');
return (
<div>
<button onClick={() => setVisibleItem("website")}>
Show Website Develpment
</button>
<button onClick={() => setVisibleItem("wordpress")}>
Show Wordpress Develpment
</button>
<button onClick={() => setVisibleItem("ecommerce")}>
Show Ecommerce Development
</button>
{visibleItem === "website" &&
<div>
<h2>Wordpress Development</h2>
<p>Info about Wordpress and all the things I can do with it</p>
</div>
}
{visibleItem === "wordpress" &&
<div>
<h2>Ecommerce Development</h2>
<p>I can do eccomerce things too</p>
</div>
}
{visibleItem === "ecommerce" &&
<div>
<h2>Website Development</h2>
<p>Info about Webdev</p>
</div>
}
</div>
);
}
ReactDOM.render(
<About/>,
document.getElementById("react")
);
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.8.4/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.8.4/umd/react-dom.production.min.js"></script>
<div id="react"></div>
If the sections were much bigger then I'd recommend splitting them out into separate components, or maybe doing an if or switch statement to select between them before the return, but the above snippet is a pattern I have used often with react.
You can create two states one holding array of button info to minimize repetition of code and another state to track the column clicked.
import React, { useState } from "react";
export default function About(props) {
const [colNum, setColNum] = useState('');
const [btnNames] = useState([
{
colId: 1,
name: "Website Develpment"
},
{
colId: 2,
name: "Wordpress Develpment"
},
{
colId: 3,
name: "Ecommerce Develpment"
}
]);
const handleClick = (id) => {
setColNum(id);
};
return (
<>
<div className="row justify-content-md-center">
{btnNames.map(element => (
<div className="col-auto" key={element.colId}>
<CustomButton onClick={()=> handleClick(element.colId)}>{element.name}</CustomButton>
</div>
))}
</div>
{colNum !== '' ? (<div className="row">
<div className="col-md-4">column {colNum}</div>
</div>) : null }
</>
);
}
So you can define showing value for each section in state, which initial should be false. Then we can handle this state with a function where built-in JS tools can be used (Object.entries, Object.fromEntries and map). The element will be displayed, the value of which will be true, and the rest will automatically become false. More details can be found here: https://codesandbox.io/s/happy-sea-nckmw?file=/src/App.js
import React, { useState } from "react";
import "./styles.css";
import styles from "./TestStyles.module.css";
import CustomButton from "./CustomButton";
export default function App() {
const [showDiv, setShowDiv] = useState({
web: false,
wordpress: false,
ecommerce: false
});
const showDivHandler = (val) => {
const newState = Object.fromEntries(
Object.entries(showDiv).map(([key, value]) => [key, (value = false)])
);
setShowDiv({
...newState,
[val]: !showDiv[val]
});
};
return (
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<div className={styles.Section}>
<div className="col-auto">
<CustomButton clicked={() => showDivHandler("web")}>
Website Develpment
</CustomButton>
</div>
<div className="col-auto">
<CustomButton clicked={() => showDivHandler("wordpress")}>
Wordpress Develpment
</CustomButton>
</div>
<div className="col-auto">
<CustomButton clicked={() => showDivHandler("ecommerce")}>
Ecommerce Development
</CustomButton>
</div>
</div>
<div className={styles.Section} style={{marginTop: 20}}>
{showDiv.web && <div className={styles.Content}>column 1</div>}
{showDiv.wordpress && <div className={styles.Content}>column 2</div>}
{showDiv.ecommerce && <div className={styles.Content}>column 3</div>}
</div>
</div>
);
}
The custom button can look like this:
import React from "react";
const button = (props) => (
<button
onClick={props.clicked}
//some other props if need it(e.g. styles)
>
{props.children}
</button>
);
export default button;
This is how I solved it. Thanks for your help!
export default function About() {
const [visibleItem, setVisibleItem] = useState(1);
const [priceItems] = useState([
{
id: 1,
name: "website",
},
{
id: 2,
name: "wordpress",
},
{
id: 3,
name: "ecommerce",
},
]);
const handleClick = (id) => {
setVisibleItem(id);
};
return (
<div className="container-fluid pricing-wrapper">
<div className="row">
<div className="col">
<h1>Pricing</h1>
</div>
</div>
<div className="row">
<div className="col">
<p>Innovation that empowers your team while also reducing risk!</p>
<div className="seperator"></div>
</div>
</div>
<div className="row justify-content-md-center">
<div className="row justify-content-md-center">
{priceItems.map((item) => (
<div className="col-auto">
<CustomButton onClick={() => setVisibleItem(item.id)}>
{item.name}
</CustomButton>
</div>
))}
</div>
</div>
{priceItems
.filter((item) => item.id === visibleItem)
.map((item) => (
<PriceItem item={item} />
))}
</div>
);
}
