I want to display text in the form of react component inside react app.
When I tried to render it, it gives me not defined error, which is understandable.
import React from 'react';
import HeaderClass from './Header.css';
import logo from '../../Assets/Images/logo.jpg'
const Header = () => {
return(
<div className="header-wrapper">
<p className="logo__tagline"> <text /> </p>
<img className="App__logo" src={logo} alt="Name" />
</div>
)
};
export default Header;
Not sure exactly what you are trying to do?
But if i understand correct you could do like this:
In the text file:
import React, { Fragment } from 'react'; // So it doesn't create a unnecessary node element. **Only available in react 16+
export const Text = () => <Fragment>Your text here</Fragment>;
and then you can bring in the text element and use it in your code:
import React from 'react';
import HeaderClass from './Header.css';
import logo from '../../Assets/Images/logo.jpg'
import { Text } from './Text'
const Header = () => {
return(
<div className="header-wrapper">
<p className="logo__tagline"> <Text /> </p>
<img className="App__logo" src={logo} alt="Name" />
</div>
)
};
export default Header;
Maybe i have misunderstood the question but i don't know why you would want to do this.

This is my App.js. Here, I call the "Profile" Component.
import './App.css';
import Profile from "./Profile"
function App() {
return (
<div className="App">
<Profile />
</div>
);
}
export default App;
Then, inside Profile.js, I call Card component and inside the Card component, I've enclosed an image.
import React from 'react'
import Card from './Card'
import styles from "./Profile.module.css"
import image1 from "./assets/profile1.png"
const Profile = () => {
return (
<Card>
<div>
<img src={image1} alt="" />
</div>
</Card>
)
}
export default Profile
Inside of Card component, I've just applied some CSS to make it look like a Card.
import React from 'react'
import styles from "./Card.module.css"
const Card = () => {
return (
<div className={styles.card}>
</div>
)
}export default Card
This is my folder structure.
I'm really confused why the image isn't getting showed up. Currently this is the output I'm getting.
I've restarted the server as well. But it's not getting fixed.
your card doesn't have a child component return maybe that could be the problem
import React from 'react'
import styles from "./Card.module.css"
const Card = ({children}) => {
return (
<div className={styles.card}>
{children}
</div>
)
}
export default Card

I have SVG files written in Function Components.
import React from "react";
const MySVGBackground= (props) => {
return (
<svg> some svg here</svg>
);
};
export default MySVGBackground;
I need to render this as a background:
<div style={{ backgroundImage: `url(${MySVGBackground})` }}> </div>
but it's not working.
I can't purely import the SVG directly, because it gives me an error of Unexpected Token. So I have to wrap the SVG into the FC and export it.
Here is the sample code:
https://codesandbox.io/s/react-background-issue-9wt4x?file=/src/App.js
Try this:
https://codesandbox.io/s/react-background-issue-ut933
import React from "react";
import "./styles.css";
import BackgroundSVG from "./backgroundSVG";
// import this to render static markup
import { renderToStaticMarkup } from 'react-dom/server';
export default function App() {
// convert component to string useable in data-uri
const svgString = encodeURIComponent(renderToStaticMarkup(<BackgroundSVG />));
return (
<div className="App">
<h2
style={{
backgroundImage: `url("data:image/svg+xml,${svgString}")`
}}
>
Svg background
</h2>
</div>
);
}
The data: image/svg+xml;utf8 part tells the browser that raw image data is following.

I have the following code that produces a Card UX Component.:
import React from 'react';
import image1 from '../images/swimming_sign.jpg';
const Card = props =>{
return(
<div className="card text-center">
<div className="overflow">
<img src="image1" alt='Image 1'/>
</div>
</div>
);
}
export default Card;
I would like to know how I can call it in one of my pages that simply produces an image at the top half of the page, and also what is the command for importing the "bootstrap.min.css" from "node_modules" in this page. The code for the page currently looks like this:
import React from 'react'
import Hero from '../Components/Hero';
import Card from '../Components/ServicesUi';
export default function Services() {
return (
<Hero hero="servicesHero"/>
);
}
Card Import
import React from 'react';
let image1 = '../images/swimming_sign.jpg';
const Card = props =>{
return(
<div className="card text-center">
<div className="overflow">
<img src={image1} alt='Image 1'/>
</div>
</div>
);
}
export default Card;
import React from 'react'
import Hero from '../Components/Hero';
import Card from '../Components/ServicesUi';
export default function Services() {
return (
<Card/>
<Hero hero="servicesHero"/>
);
}
To import css file from node modules, please place the link statement in your index.html file
<link rel="stylesheet" href="./node_modules/bootstrap/bootstrap.min.css">
I'm fairly new to React and trying to create an App that when you search in the input box it filters out the wrong drivers and only presents you with the correct one. I'm trying to use hooks instead of class components. I have a working project in CodeSandBox: https://codesandbox.io/s/hungry-turing-2n2tj
I've looked at some other answers on stack overflow as well as reading the docs that the React Team has but it is all going above my head. Let me know if there is any more documentation that I can provide! Thanks in advance!
You are looking for something like this: https://codesandbox.io/s/distracted-frog-d5ocw
Basically pass the drivers to the list from the app component and filter it out based on the search term provided by the searchbox component
Your App.js:
import React from "react";
import "./styles.css";
import CardList from "./card-list";
import SearchBox from "./searchbox";
import allDrivers from "./drivers";
export default function App() {
const [drivers, setDrivers] = React.useState(allDrivers);
return (
<div className="App">
<h1>F1 Drivers</h1>
<SearchBox
onSearch={v => {
console.log(v);
if (!v) {
setDrivers(allDrivers);
return;
}
setDrivers(drivers.filter(d => d.name.toLowerCase().startsWith(v)));
}}
/>
<CardList drivers={drivers} />
</div>
);
}
your cardlist would look like
import React from "react";
import Card from "./Card";
function CardList(props) {
return (
<div className="card-list">
{props.drivers.map(createCard => (
<Card
key={createCard.id}
name={createCard.name}
imgURL={createCard.imgURL}
number={createCard.number}
team={createCard.team}
age={createCard.yearsOld.age}
country={createCard.country}
/>
))}
</div>
);
}
export default CardList;
and searchbox is simply
import React from "react";
import "./drivers";
function SearchBox(props) {
return (
<input
onChange={e => {
props.onSearch(e.target.value);
}}
type="text"
// value={props.value}
/>
);
}
export default SearchBox;
In reactjs, I have already created one component and added it to my Main.js file but now, I need to add one more component to it and due to JSX restriction of having only one root element per JSX, I cannot add one more component to it. I don't know where I'm going wrong in this.
`~~~~index.js file`
import React from "react";
import ReactDOM from "react-dom";
import Main from "./Main";
ReactDOM.render(
<Main/>,
document.getElementById("root")
);
-------------------------------------------------------
Main.js file
import React, { Component } from "react";
import Header from './Header';
// import Body from './Body';
import './index.css';
class Main extends Component {
render() {
return (
<div className="Main">
<Header image={require('./demo.jpg')}/>
{/* <Body/> */}
</div>
);
}
}
export default Main;
-------------------------------------------------------
Header.js file
import React from 'react'
import './Header.css';
// import Body from './Body';
export default (props) => {
const style= {
backgroundImage : "url(" + props.image + ")"
}
return (
<div className="body" style={style}>
<button className="btn" > Drawer </button>
<h1 className="heading1"> Questions </h1>
<button className="heading2"> Eye Button </button>
<h2 className="heading3"> Hi.. Sandeep Gautam </h2>
<h3 className="heading4"> Mind answering a few questions </h3>
</div>
)
}`
