UPDATE: After a bit of research importing modules between several <script> tags is now possible.
This can be achieved adding the Babel Plugin attribute data-plugins and setting the value to "transform-es2015-modules-umd" which will enable the UMD pattern.
You’ll also need to set type="text/babel" on each <script> tag.
This will allow you to use the import statements directly inside each file. Like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>React</title>
<script src="https://unpkg.com/react@16/umd/react.development.js"></script>
<script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>
<script src="https://unpkg.com/babel-standalone@6/babel.min.js"></script>
</head>
<body>
<div id="root"></div>
<script data-plugins="transform-es2015-modules-umd" type="text/babel" src="./Header.js"></script>
<script data-plugins="transform-es2015-modules-umd" type="text/babel" src="./App.js"></script>
</body>
</html>
Working Gist Example
I am trying to inject some React code into an HTML document. I am following React’s own documentation and feeding their starter code (a simple like button) into the page. Everything was working great. I changed it to use JSX, changed it to a functional component using hooks instead of a class component with state. No problems.
However, whenever I include an import call and try to bring in another component, the component breaks on the page and stops displaying, but doesn’t throw any kind of error I can see.
How do I develop in a “react-y” way with components and modularity while injecting it into an html page?
Here is the code I’m working with at the moment:
HTML document
<body>
<div id="react-root"></div>
<!-- inject react, reactDOM and JSX engine -->
<script src="https://unpkg.com/react@16/umd/react.development.js" crossorigin></script>
<script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js" crossorigin></script>
<script src="https://unpkg.com/babel-standalone@6/babel.min.js"></script>
<!-- point to component -->
<script src="transpiled/app.js"></script>
</body>
React Component
'use strict';
import {SecondComponent} from './components/SecondComponent';
const e = React.createElement;
const LikeButton = () => {
const [liked, setLiked] = React.useState(false);
if (liked) return 'You liked this functional component.'
const handleLikeClick = () => {
setLiked(true);
}
return (
<div>
<button onClick={handleLikeClick}>new like button with jsx</button>
{liked && <SecondComponent/>}
</div>
)
}
const domContainer = document.querySelector('#react-root');
ReactDOM.render(e(LikeButton), domContainer);
Like I said, any sort of import statement seems to be where it breaks. Can’t find resources online about it. Thanks in advance for your help!
