It works perfectly because I haven\'t included JSX, but when I replace the script type with text/babel, it doesn\'t work because the module fails to load. bro

    As mentioned in the docs, it's added in: v7.10.0.

    If you want to use your browser's native support for ES Modules, you'd normally need to set a type="module" attribute on your script tag.

    With @babel/standalone, set a data-type="module" attribute instead, like this:

    <script type="text/babel" data-type="module">

    I think the question was if it is possible to use a script tag with two or more types at the same time (e.g. something like type="module, txt/babel"). As far as I know the answer is NO.

    JonDotsoy's answer helps with reduce typing React.createElement over and over again but even with such a "variable shortcut" it's not as comfortable as JSX when using larger templates with nested elements because h('div', {}, 'hello!!')... is difficult to maintain in such cases.

    The only way I found to combine native browser module support and in-browser Babel for JSX without using any build tool is this ... a rather dirty hack that uses eval and should not be used for production apps:

    index.html

    <body>

    <div id="app"></div>


    <!-- Scripts ------- -->
    <script src="vendor/js/babel.min.js"></script>
    <script src="vendor/js/react.development.js"></script>
    <script src="vendor/js/react-dom.development.js"></script>
    <script src="app/app.js" type="module"></script>

</body>

    app/app.js

    import ComponentOne from "./ComponentOne.js";


let template = `
<div>
    <h1>Heading</h1>
    <hr />
    <ComponentOne msg="MsgText-ComponentOne" />
</div>
`;


const App = () => {
    return (
        eval(Babel.transform(template, { presets: ['es2017', 'react'] }).code)
    );
};


ReactDOM.render(
    React.createElement(App, null),
    document.getElementById("app")
);

    app/ComponentOne.js

    import ComponentTwo from "./ComponentTwo.js";


let template = `
<div>
    <h2>This is ComponentOne</h2>
    <p key="2">Property "msg" content: {props.msg}</p>

    <ComponentTwo msg="MsgText-ComponentTwo" />
</div>
`;


const ComponentOne = (props) => {
    return(
        eval(Babel.transform(template, { presets: ['es2017', 'react'] }).code)
    );
};

export default ComponentOne;

    app/ComponentTwo.js

    let template = `
<div>
    <h2>This is ComponentTwo</h2>
    <p key="2">Property "msg" content: {props.msg}</p>
</div>
`;


const ComponentTwo = (props) => {
    return(
        eval(Babel.transform(template, { presets: ['es2017', 'react'] }).code)
    );
};

export default ComponentTwo;

    Just in case if some one comes here looking for answer

    There is a support for data-plugins and data-presets in babel standalone

    <script data-plugins="transform-es2015-modules-umd" type="text/babel">

    see more here Babel standalone

    you may prefer to use an alias to createElement. This way is faster for the engine. For example use h or e.

    const { createElement: h } = React;

const App = () => {
   return h('div', {}, 'hello!!'); 
}

    Otherwise, it is possible to use @babel/standalone module, please see more on here https://babeljs.io/docs/en/next/babel-standalone.html.

    <div id="app"></div>
<!-- Load Babel -->
<script src="https://unpkg.com/@babel/standalone/babel.min.js"></script>
<!-- Your custom script here -->
<script type="text/babel">
const { render } = ReactDOM;

const App = () => {
    return <div>hello!!</div>
}

render(<App />, document.getElementById('app'));
</script>
