@gaearon How to pass props in button component?

Hi I have resolved this bug, make sure the file name matches the React Component so e.g

<script src="like_button.js"></script>

file name in script must be like_button.js_ they must match and like button will appear

Thank you.

If I use the three lines of code from this page:

https://reactjs.org/docs/add-react-to-a-website.html

const domContainer = document.querySelector('#like_button_container'); const root = ReactDOM.createRoot(domContainer); root.render(e(LikeButton));

The LIKE button does not appear on the html page.

But if I use just the last two lines in the downloaded js file the LIKE button does appear:

const domContainer = document.querySelector('#like_button_container'); ReactDOM.render(e(LikeButton), domContainer);

I don't know enough js/react to know what the above 3 lines does not work but the 2 lines does.

It is rather troubling especially when I am brand new to react and I am told that the react docs are the best place to learn react and I have flunked on the very first item....

same here i couldnt make it work, weird situation

Thank you for this.
Is there a way to re-render the React component based on some action on the HTML page?
For example, changing a date filter and re-rendering the React component with new values for the props (the dates to filter by).

Unzip the downloaded file and open its contents using an IDE of your choice. You can use a live server to publish the content of your html file. The problem is that the script tag is not able to locate the referenced script file.

@gaearon How to pass props in button component?

Try out https://github.com/michaldoda/react-supervisor#readme. Haven't personally tested it, but looks promising.

At the moment I'm looking into https://github.com/michaldoda/react-supervisor#what-it-does. Seems like it might do what you desire, you can give it a shot.
