I Create a react.js component and it doesn't render - reactjs

I Create a component and it doesn't render (react js) < --- completely newbie react js user
first i create well structure of a card in list
meetupitems.js
import { Action } from 'history';
import css from './Meetupitems.module.css';
function Meetupitem(props) {
<li className={css.item}>
<div className={css.image}>
<image src={props.image} alt={props.title} />
</div>
<div className={css.content}>
<h3>{props.title}</h3>
<address>{props.address}</address>
<p>{props.description}</p>
</div>
<div className={css.actions}>
<button></button>
</div>
</li>;
}
export default Meetupitem;
then use map() to create card list from "list of data"
Meetuplist.js
import Meetupitem from "./Meetupitems";
import css from "./Meetuplist.module.css";
function Meetuplist(props) {
return (
<ul className={css.list}>
{props.meetups.map((meetup) => (
<Meetupitem
key={meetup.id}
title={meetup.title}
image={meetup.image}
address={meetup.address}
description={meetup.description}
/>
))}
</ul>
);
}
export default Meetuplist;
and when i'm trying to use it
Allmeetup.js
import Meetupitem from "./Meetupitems";
import css from "./Meetuplist.module.css";
function Meetuplist(props) {
return (
<ul className={css.list}>
{props.meetups.map((meetup) => (
<Meetupitem
key={meetup.id}
title={meetup.title}
image={meetup.image}
address={meetup.address}
description={meetup.description}
/>
))}
</ul>
);
}
export default Meetuplist;
the result I saw was a blank page at the index route(where the list should show)
but others route was fine
I can't figure out what's wrong

I think the issue is nothing is being returned from your Meetupitem component. There is no return statement in it.
I believe if you look in console in chrome dev tools, you will be able to see the error messages for it.
Try changing it to as shown below:
import { Action } from 'history';
import css from './Meetupitems.module.css';
function Meetupitem(props) {
return (
<li className={css.item}>
<div className={css.image}>
<image src={props.image} alt={props.title} />
</div>
<div className={css.content}>
<h3>{props.title}</h3>
<address>{props.address}</address>
<p>{props.description}</p>
</div>
<div className={css.actions}>
<button></button>
</div>
</li>;
)
}
export default Meetupitem;

about gatsby link issue

I created my own blog with gatsby and contentful using template. And I was tring to change subdirctory of my arcticels. article URLs are working now but links in index page is not working.
import React from 'react'
import { Link } from 'gatsby'
import { GatsbyImage } from 'gatsby-plugin-image'
import Container from './container'
import Tags from './tags'
import * as styles from './article-preview.module.css'
const ArticlePreview = ({ posts }) => {
if (!posts) return null
if (!Array.isArray(posts)) return null
return (
<Container>
<ul className={styles.articleList}>
{posts.map((post) => {
return (
<li key={post.slug}>
<Link to={`/${post.category}/${post.slug}`} className={styles.link}>
<GatsbyImage alt="" image={post.heroImage.gatsbyImageData} />
<h2 className={styles.title}>{post.title}</h2>
</Link>
<div
dangerouslySetInnerHTML={{
__html: post.description.childMarkdownRemark.html,
}}
/>
<div className={styles.meta}>
<small className="meta">{post.publishDate}</small>
<Tags tags={post.tags} />
</div>
</li>
)
})}
</ul>
</Container>
)
}
export default ArticlePreview
I changed to <Link to={/${post.category}/${post.slug}} from <Link to={/${post.slug}}. but somehow links are like http://localhost:8000/undefined/(article-slug). It shold be category name as I set up in Comtentful insted of 'undefined'.
do you have any suggestions?
if I use subdir like /blog/, its working. and Link to={/${post.slug}/${post.slug}} also work.

Why do my pictures not render when using react?

I used default create-react-app to create a react app. However, when i try to add cards that contain pictures my image does not render. I get a white screen....
My image is located in a folder in src called Images. The rest works until I add in the Card prop and then the screen goes fully white. So I suppose that means it is not working or rendering properly.
import React from 'react';
export default function Card(props) {
return (
<div className="card">
<img src={require("./Images/monstera.jpeg")} alt="monstera"></img>
<div className="card-stats">
<p>{props.name}</p>
<p>{props.price}</p>
</div>
</div>
)
}
import logo from './logo.svg';
import './App.css';
import React from 'react';
import Header from './Components/Header';
import Inventory from './Components/Inventory';
import Cart from './Components/Cart';
import data from './data';
import Card from './Components/Card';
function App() {
return (
<div className="App">
<Header></Header>
<div className="row">
<Inventory>
<div className="cards-list">
<Card>
</Card>
</div>
</Inventory>
<Cart></Cart>
</div>
</div>
);
}
export default App;
Is there something I am doing wrong? Is there a special way to render a react app with an image?
look for any error through console and try cleaning your code a little
turn this
function App() {
return (
<div className="App">
<Header></Header>
<div className="row">
<Inventory>
<div className="cards-list">
<Card>
</Card>
</div>
</Inventory>
<Cart></Cart>
</div>
</div>
);
}
export default App;
into this
function App() {
return (
<div className="App">
<Header />
<div className="row">
<Inventory />
<div className="cards-list">
<Card />
</div>
<Cart />
</div>
</div>
);
}
export default App;
if not required don't use so many div

How can I link to another website in React?

I have these div cards with some information, and I would like to insert a link inside them, that redirects to another site. It didn't work with <a></a>. can anybody help me?
Thanks!
import React from "react";
function Card(props) {
return (
<div className="card">
<img className="img-logo" src={props.img} alt="image_logo" />
<h3 className="name"> {props.name}</h3>
<p className="paragraph"> {props.description}</p>
<a href={props.link}>Page</a>
</div>
);
}
export default Card;
You can use the <Link> component from react router.
If you are opening the url in new tab, make sure to use noopener and noreferrer so that the browser does not attach the current website's window variable to the newly opened url in the new tab, which can be a security loophole.
import { Link } from 'react-router-dom';
export const openInNewTab = (url) => {
const newWindow = window.open(url, '_blank', 'noopener,noreferrer');
if (newWindow) newWindow.opener = null;
};
function Card(props) {
return (
<div className="card">
<img className="img-logo" src={props.img} alt="image_logo" />
<h3 className="name"> {props.name}</h3>
<p className="paragraph"> {props.description}</p>
<Link href="#" onClick = {() => openInNewTab(props.link)}>Page</Link>
</div>
);
}

Image doesn't display React

I'm building a website by react and my local image doesn't display. I use props to pass the properties from Cards.js to CardItem.js then every properties display except image. I don't know what is a problem with my code :(
Here is Cards.js:
import React from 'react'
import CardItem from './CardItem'
import './Cards.css'
function Cards() {
return (
<div className="cards">
<h1>Check out these EPIC Destinations!</h1>
<div className="cards-container">
<div className="cards-wrapper">
<ul className="cards-items">
<CardItem
src='../assets/images/img-9.jpg'
text='Explore the hidden waterfall deep inside the Amazon Jungle'
label='Adventure'
path='/sevices'
/>
</ul>
</div>
</div>
</div>
)
}
export default Cards
CardItem.js:
import React from 'react'
import { Link } from 'react-router-dom'
function CardItem(props) {
return (
<>
<li className="cards-item">
<Link className="cards-item-link" to={props.path}>
<figure className="cards-item-pic-wrap" data-category={props.label}>
<img src={props.src} alt="Travel Img" className="cards-item-img" />
</figure>
<div className="cards-item-info">
<h5 className="cards-item-text">{props.text}</h5>
</div>
</Link>
</li>
</>
)
}
export default CardItem
we want to import the image first
import img from './assets/images/img-9.jpg';
We named image as img use it in your code.
import React from 'react'
import CardItem from './CardItem'
import './Cards.css'
import img from './assets/images/img-9.jpg';
function Cards() {
return (
<div className="cards">
<h1>Check out these EPIC Destinations!</h1>
<div className="cards-container">
<div className="cards-wrapper">
<ul className="cards-items">
<CardItem
src={img}
text='Explore the hidden waterfall deep inside the Amazon Jungle'
label='Adventure'
path='/sevices'
/>
</ul>
</div>
</div>
</div>
)
}
export default Cards
first import image
import img from '../assets/images/img-9.jpg'
then use it
<CardItem src={img} .../>
I hope this helps you, resources https://create-react-app.dev/docs/using-the-public-folder/:
for Cards.js file:
...
<CardItem
src='/images/img-9.jpg'
text='Explore the hidden waterfall deep inside the Amazon Jungle'
label='Adventure'
path='/services'
/>
And...
for CardItem.js file:
...
<img
className='cards__item__img'
alt='Travel'
src={process.env.PUBLIC_URL + props.src}
/>

how can i display active route name in text reactjs

i tried like ${route} but to be honest i have no idea.
i want to put some helpful links bottom of website and it must show active links name to belong links
import React from 'react'
import './Links.css';
function Links() {
return (
<div>
<div className="links_person">
<div className="links_right_2">
<div className="links_right_cild_2">
<span className="links_span"> You can take look and learn more
about ${route}
</span>
</div>
</div>
</div>
</div>
)
}
export default Links
you can check current route by using useLocation from react-router-dom
something like this
import { useLocation } from 'react-router-dom';
import React from 'react';
import './Links.css';
function Links() {
const location = useLocation();
return (
<div>
<div className="links_person">
<div className="links_right_2">
<div className="links_right_cild_2">
<span className="links_span">
You can take look and learn more about : {location.pathname}
</span>
</div>
</div>
</div>
</div>
);
}
