I am using React and Firebase and receive the following when logged in
photoURL: https://graph.facebook.com/10157648190117379/picture
If I try to display this in JSX using:
<image src={this.props.user.photoURL} />
nothing renders.
I notice navigating directly to the link doesn't actually show an image, but prompts a download. Any ideas?
Thanks.
Yes, it won't work. Because there is a typo and there is no tag named Image in HTML.
To display an image, you have to use an img tag.
import React from 'react';
import './App.css';
class App extends React.Component {
state = { url: 'https://graph.facebook.com/10157648190117379/picture'}
render() {
return <img alt='Profile' src={this.state.url} />;
}
}
export default App;
No Problem in the URL. Just make sure to use the correct tag.
I try this and it work
import React from "react";
const TestCompOne = (props) => {
console.log("[TEST COMP 1]");
return (
<div>
<img src={"https://graph.facebook.com/10157648190117379/picture"} />
</div>
);
};
export default TestCompOne;

I"m trying to render username comments with likes and a like. please see image on demo.
All of this comes form data.json
I can't find a way to display the json properly on the tags. What am I missing here?
Sorry I'm trying my best here with react as I'm quite a beginner.
demo
my index.js
import React from "react";
import styles from "./styles";
import { getCaptionFromEdges } from "./helpers";
const Posts = (props) => {
const { data } = props;
return (
<img src={data.owner.profile_pic_url} /> // this tag works
<p>{data.owner.node.username}</p> // this tag doesn't work
<hr>
//here I should display all comments with its like.
<p>{data.node.text}</p>// this doesn't work
);
};
export default Posts;
You need to wrap your elements with another element (or a Fragment). Try the following:
import React from "react";
import styles from "./styles";
import { getCaptionFromEdges } from "./helpers";
const Posts = (props) => {
const { data } = props;
return (
<>
<img src={data.owner.profile_pic_url} />
<p>{data.owner.node.username}</p>
<hr />
<p>{data.node.text}</p>
</>
);
};
export default Posts;
I have this component called SearchBarScreen :
import React, { useEffect } from "react";
import "./index.scss";
export const SearchBarScreen = (props) => {
return (
<>
<img src="./assets/img/logo.png" className="nav_logo" alt="logo mercadolibre" />
</>
);
};
and my project has this structure:
depending on where I call this component, the image can be broken.
for example in the previous image it can be seen under the folder src/components/items/components, where it is called SearchBarScreen. For example, the image is shown broken on ItemDetailScreen but not on ItemScreen.
I always call it the same way in both components:
return (
<>
<SearchBarScreen props={props} />
</>
);
In ItemDetailScreen
In ItemDetailScreen
If you want the image loading to consistently work, you'll need to import the Image as if it was a component instead of the style you generally use with standard HTML.
Like so:
import React, { useEffect } from "react";
import Logo from '../path/to/image';
import "./index.scss";
export const SearchBarScreen = (props) => {
return (
<>
<img src={Logo} className="nav_logo" alt="logomercadolibre" />
</>
);
};
Edit:
If you absolutely have to use the public folder, which I don't recommend, here's how you do it: https://create-react-app.dev/docs/using-the-public-folder/
You'd basically make the path absolute instead of relative.

Community, I rendered more than one component from a single page and the problem I receive is:
[./src/App.js Attempted import error: 'Greeting' is not exported from './components/Home'.]
Can anybody tell me why?
App.js
import "./App.css";
import { Home, Page, Greeting } from "./components/Home";
function App() {
return (
<div className="App">
<Home />
<Page />
<Greeting />
</div>
);
}
export default App;
Home.js
import React, { Component } from "react";
import React from "react";
class Home extends Component {
render() {
return (
<div className="box">
<h1>Its a box man!</h1>
</div>
);
}
}
class Page extends Component {
render() {
return (
<div className="box">
<h1>Its a second box man! from the other Component</h1>
</div>
);
}
}
const Greeting = () => {
return <h1>Hello again</h1>;
};
export { Home, Page, Greeting };
*The aim to practice two components from the same page, rather than just separating them.
Try to export all components one by one in Home.js like this:
export class Home...
export class Page...
export const Greeting...
And after that delete this line:
export { Home, Page, Greeting };
Change
const Greeting = () => {
return <h1>Hello again</h1>;
};
to
export const Greeting = () => {
return <h1>Hello again</h1>;
};
and your issue should be resolved
Try this in Home.js. If you export module as default, you can import without parenthesis {}. But if you export without default, you have to import using parenthesis.
export default { Home, Page, Greeting };
I tested your code and there was no problems except if these are not typos:
you haven't imported react in your App.js
you've imported react twice in your Home.js
The only problem I can think of is that you have forgotten to save Home.js.
If you've saved Home.js:
exit you're dev server using ctrl + c and start it again and see if the problem is resolved.
try removing Greeting Component and let us know if you still get errors.
I am learning to develop a multi-page app with React Router. I have been following a tutorial and have managed to set up multiple page without any content. However, I want to add the original main content of the home page that was originally running properly before I used react-router. If I delete the code that is in the div called App, I have added in Home.js, then I can go back to switching between blank pages with no errors:
import React from 'react';
//import "./App.css";
import List from "./List";
import Title from "./Title";
import Ending from "./Ending";
import MoviePage from "./MoviePage";
const home = () => {
return (
<div className="App">
<Title pics={this.state.pics} changePageNumber={this.changePageNumber}/>
<List parentCallback={this.loadMoviePage} movieList={this.state.movieList}/>
<Ending toad={this.state.toad} speedUp={this.state.speedUp}/>
</div>
);
}
export default home;
So I know that I am not able to access the content from this.state.pics.(Nor the other 3 components). I created this content(and by content I mean the arrays that have the general information, i.e image location, etc). in App.Js so I am wondering how can I pass it in to this new Home.js file?
You can not access state in stateless component , if you need some data from another component you need to pass it as props from parent to children , just to show you i just make an example of your code follow it, you will get it
App.js
import React from 'react';
import Home from "./Home";
class App extends Component {
constructor() {
super();
this.state = {
pics: YourArrayDataHere,
};
}
render () {
return (
<Home pics={this.state.pics} />
);
}
export default App;
Home.js
import React from 'react';
//import "./App.css";
import List from "./List";
import Title from "./Title";
import Ending from "./Ending";
import MoviePage from "./MoviePage";
const home = (props) => { //access throught props
return (
<div className="App">
<Title pics={props.pics} />
</div>
);
}
export default home;
I'm still new to React and after I finished the tutorial I wanted to create something myself.
I've passed the url to make a backgroundImage style and add borders to try it out. Unfortunately I can see the img being set in the css but it won't actually display as expected.
As a test I also tried a simple img with src attribute set to my image and nothing would display.
I made a folder called img inside the src
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
class App extends Component {
render() {
return (
<div className="App">
<Home/>
</div>
);
}
}
function Portfolio(props) {
const stylee = {
backgroundImage:'url('+props.imgURL+')',
borderWidth: 1,
};
const ide = 'portfolio'+props.counting;
return (<div id={ide} style={stylee} className='portfolio'/>)
}
class Home extends Component {
renderPortfolio(count,img){
return <Portfolio counting={count} imgURL={img}/>
}
render(){
return(
<div>
{this.renderPortfolio(1,'./img/1.jpeg')}
{this.renderPortfolio(2,'./img/2.jpeg')}
{this.renderPortfolio(3,'./img/1.jpeg')}
<img src='./img/1.jpeg'/>
</div>
)
}
}
export default App;
What am I doing wrong that is preventing the images from displaying ?
edit-- I've changed my code to the working solution
Instead of passing the local img url, I used require() first then pass the image to props.
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
class App extends Component {
render() {
return (
<div className="App">
<Home/>
</div>
);
}
}
function Portfolio(props) {
const counter = 'portfolio'+props.counting;
const loadGambar = props.gmbr;
// const loadGambar2 = require(props.gmbr);
const stylee = {
borderColor:props.color,
border:1,
borderWidth: 10,
backgroundImage: "url("+loadGambar+")",
}
return(
<div id={counter} className='portfolio' style={stylee}>
</div>
)
}
class Home extends Component {
renderPortfolio(count,gambare){
return <Portfolio counting={count} gmbr={gambare}/>
}
render(){
return(
<div>
{this.renderPortfolio(1,require('./img/1.jpg))}
{this.renderPortfolio(2,require('./img/1.jpg'))}
{this.renderPortfolio(3,require('./img/2.jpg'))}
</div>
)
}
}
export default App;
Here's a link to a working example based on your code: sandbox link.
The problem with setting a background image is that it adapts to the dimensions of the div. In your case your div is empty in Portfolio so its dimensions are 0x0 and the image won't show. You will see from the link that I update the style and everything shows. Now the only issue you might have is that you don't have an image loader in your webpack configuration, if you are starting with react I would recommend create-react-app.
