I am trying to use altmetrics in one of the my article (PDF) in my website.
I tried to add the altmetric badges (here) to in reacts js but I could not manage.
Here is my trial:
First I tried to create a component and add to the page
class DownloadPDF extends Component {
render() {
return (
<div>
<script type="text/javascript" src="https://d1bxh8uas1mnw7.cloudfront.net/assets/embed.js"></script>
<div data-badge-details="right" data-badge-type="medium-donut" data-doi={"my-doi-number-here"} class="altmetric-embed"> </div>
Download PDF
</div>
);
}
}
The second is I tried to put in the page directly:
<div>
<script type="text/javascript" src="https://d1bxh8uas1mnw7.cloudfront.net/assets/embed.js"></script>
<div data-badge-details="right" data-badge-type="medium-donut" data-doi="my-doi-number-here" class="altmetric-embed"> my-crosreff-doi.pdf</div>
{<DownloadPDF />}
</div>
Can someone know how can I put altmetrics badges correctly in reactJS?
Thank you all answers.
For seeing the Altmetrics result in your page first you should add:
altmetrics external javascript file
<script type='text/javascript'src='https://d1bxh8uas1mnw7.cloudfront.net/assets/embed.js'></script>
2.
You should add your DOI wherever you want to display
<div class='altmetric-embed' data-badge-type='donut' data-doi="10.1038/nature.2012.9872"></div>
so this is for adding to html page but when you add in ReactJS web app we have a tiny problem.
Problem is adding external javascript file to in ReactJS page that you want to display the Altmetrics badge
So solution is we need to install an addition library that allows us to implement any external javascript file.
Check the link:
https://github.com/shaneosullivan/ReactDependentScript/
We need to add below code in your ReactJS page
...
render() {
return (
<div>
<ReactDependentScript
loadingComponent={<div></div>}
scripts={['https://d1bxh8uas1mnw7.cloudfront.net/assets/embed.js']}
>
<div></div>
</ReactDependentScript>
...
</div>
);
}
}
then you can add your the Altmetrics badge wherever you want in the page like this
<div data-badge-details="right" data-badge-type="medium-donut" data-doi="doi-numberhere" class="altmetric-embed"></div>
I think all you need to do as described https://api.altmetric.com/embeds.html
that you put the js script in any where in html , but react is virtual dom , so all you need is put in puplic in index.html in <body> under <div id"root"></div>
or like you named. just simple as that
There are two things you are missing
Adding the script to index.html file underpublicdirectory (if you have created your app usingcreate-react-app`)
<!DOCTYPE html>
<html lang="en">

<meta name="theme-color" content="#000000">
<link rel="manifest" href="%PUBLIC_URL%/manifest.json">
<!-- Here we go with the external script -->
<script type='text/javascript' src='https://d1bxh8uas1mnw7.cloudfront.net/assets/embed.js'></script>

Change the class attribute to className in dom
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
class App extends Component {
render() {
return (
<div className="App">
// changed class to className
<div className='altmetric-embed' data-badge-type='donut' data-doi="10.1038/nature.2012.9872"></div>
</div>
);
}
}
export default App;

I am trying to use React with MS Visual Studio Code. If I ran the program from the terminal, I get following error message: "Cannot use import statement outside a module"
If I run the program without terminal, it takes me to the browser (Firefox) and gives "File not found" error message.
Not sure how the above two are connected. Is this is a problem with node installation, location of my files (where I do the actual programming), or perhaps is has something to do with Firefox debugger.
Kindly ask for help.
Many thanks.
Here is the code:
import React from "react";
import { ReactDOM } from "react-dom";
class App extends React.Component {
render() {
return (
<div>Test div</div>
);
}
}
ReactDOM.render(<App />, document.getElementById("App"));
I am also providing a code to my .html, in case it is relevant:
<!DOCTYPE html>
<html lang="eng">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<h1 id="test">Testing the system</h1>
<script src="/src/Dejan/Kalkulator/calc.js"></script>
</body>
<div id="App"></div>
</html>
Hey Deyan doesn't add into the HTML file, because react will automatically handle that, and also don't use CSS in HTML it will cause weird behavior at the end.
And don't put App div outside of the body tag. Because inside that div your whole react app will be fitted.
import React from "react";
import { ReactDOM } from "react-dom";
import "./Dejan/Kalkulator/calc.css"; // and add css like this I don't know your file path use the correct I put randomly.
class App extends React.Component {
render() {
return (
<div>Test div</div>
);
}
}
ReactDOM.render(<App />, document.getElementById("App"));

I've tried to put <script src="https://www.wiris.net/demo/plugins/app/WIRISplugins.js?viewer=image"></script> in the <head> of my index.html using reactjs, however, for some reason this didn't work for me.

When I run the app the math equation remains not displaying and I received on console the 404 error, as the script wasn't able to access the Wiris URL and get the plugin.
Current results:
a3xy=∞∅π
21,4 mol ⇄ a∆N
Expected results:
Could someone help me? I've read the documentation on the Wiris website (https://docs.wiris.com/en/mathtype/mathtype_web/integrations/mathml-mode), but I wasn't able to identify why this didn't work.
Add the below script to your index.html or the page where you want to render mathml
<script type="text/javascript" async src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.4/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
Create a new component which will be used to render your math equations
function Latex(props) {
const node = React.createRef();
const renderMath = () => {
window.MathJax.Hub.Queue(['Typeset', window.MathJax.Hub, node.current]);
};
useEffect(() => {
renderMath();
});
return (
<div ref={node} {...props}>
{props.children}
</div>
);
}
Wrap your content with <Latex /> component and it will render your equations
I'm starting to learn reactjs at the moment. I'm wondering how to add normal HTML-Tags in a react-app. Is i just possible to add them by using the render function or can I also just write normal HTML-Tags in my index.html file?
Cause when I'm doing so they're not displayed.
Just like:
const myelement = (<h1>some element</h1>);
ReactDOM.render(myelement, document.getElementById('root'));
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>
<div>
<div id="root"></div>
<div>just normal html</div>
</div>
Well, it works just fine here.. so there must be something wrong with my build..
If you're starting out, I recommend you bootstrap your apps using npx create-react-app. It'll give you a good sense of what a React app could look like, and some pointers for file structure.
Most React apps have an index.html file, which you can use like any normal HTML file. But, for the majority of your app, it's recommended to write your content in JSX (otherwise, you aren't getting the benefits of using React in the first place).
JSX
JSX looks very similar to regular HTML, with a handful of key differences:
Tag attributes tend to be in lowerCamelCase (onChange rather than onchange)
Instead of class (which is a reserved keyword in JavaScript), you need to use className
An Example Component
I've borrowed this sample code from React's official tutorial, which you should definitely check out if you haven't already.
This is a class Component, and your JSX goes inside of the render method:
import React from 'react';
class ShoppingList extends React.Component {
render() {
return (
<div className="shopping-list">
<h1>Shopping List for {this.props.name}</h1>
<ul>
<li>Instagram</li>
<li>WhatsApp</li>
<li>Oculus</li>
</ul>
</div>
);
}
}
What goes in index.html?
The only essential part of index.html is a <div id="root"></div>, which React will use to append the rest of the JSX.
This is also the place to add the usual metadata and icons.
As an example, here's the index.html file that comes with create-react-app. For most of my projects, I leave this pretty-much as-is:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta
name="description"
content="Web site created using create-react-app"
/>
<link rel="apple-touch-icon" href="logo192.png" />
<!--
manifest.json provides metadata used when your web app is installed on a
user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/
-->
<link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
<!--
Notice the use of %PUBLIC_URL% in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.
-->
<title>React App</title>
</head>
<body>
<noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
<!--
This HTML file is a template.
If you open it directly in the browser, you will see an empty page.
You can add webfonts, meta tags, or analytics to this file.
The build step will place the bundled scripts into the <body> tag.
To begin the development, run `npm start` or `yarn start`.
To create a production bundle, use `npm run build` or `yarn build`.

</body>
</html>
In any given React component, there can only be one parent/top layer html element. You can get around this by using <React.Fragment> ...the rest of your html ... </React.Fragment> (or <>...</> depending on your version) or simply add a wrapping <div> around everything. JSX doesn't distinguish between "normal" html and "React" html, it just turns the React stuff into normal html (over simplification, but close enough for this question). Try it again and let me know if you encounter any problems.
const reactElement = (
<div>
React stuff
</div>
);
ReactDOM.render(
reactElement,
document.getElementById('root')
);

<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>
<div>
<div id="root">
</div>
<div>
just normal html
</div>

I'm building a web single-page app with react that connects with my express backend using a socket.io websocket. I checked that the socket.io script is being loaded right in my index.html file. I've also declared a variable named socket in the same place to make the socket accessible from the react component scripts. The intent is to use this variable inside my react components. But jsx compiler says:
9:2 error 'socket' is not defined no-undef
If I check the 'socket' var at chrome console everything looks right. I guess that this var should be defined at compile time, but how?
Here goes the react component code.
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
class App extends Component {
componentDidMount(){
socket.on('hello', function(){
console.log('YAY!');
})
}
render() {
return (
<div className="App">
<div className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<h2>Welcome to React</h2>
</div>
</div>
);
}
}
export default App;
Here goes my index.html code.
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="shortcut icon" href="favicon.ico">
<title>React App</title>
<script src="/socket.io/socket.io.js"></script>
<script type="text/javascript">
var socket = io.connect('http://localhost:3001')
</script>
</head>
<body>
<div id="root"></div>
</body>
</html>
first install socket.io like this:
npm install socket.io --save
then you should import socket.io as a module just like you did with react:
import socket from 'socket.io'
Solution here.
Remove all the socket.io scripts on index.html
Import the right module in your component:
import io from 'socket.io-client';
Use it this way:
componentWillMount(){
this.socket = io('http://localhost:3001');
this.socket.on('hello', function(){
console.log('YAY!');
})
}

I'm trying to render a small search bar onto my website, but what I see is that it is still existing in the website, but its size becomes 0x0, and I can't find anything wrong with my ES6 code. Can someone debug for me please?

First of, you have defined your component as <searchBar\>. I guess React is not able to see it as JSX Component and is embedding it as a plain html tag instead, as evidenced by the <searchbar\> tag seen in Elements tab of chrome.
I think what you need is, to figure out why react is not able see searchBar as a JSX component. I hope this leads you to the right direction.
OK my boss actually found it out, it's the problem about CAPITALIZING the variable names. After I cap the first letter of the variable names things are working again...
Your search bar code works fine. Check your CSS to make sure that your body has a size.
