PLEASE HELP! My Markdown Previewer doesn't display

[mz.empress2u]

Hello
I need help with this Markdown Previewer. I am not quite certain if the problem lies with my JS and CSS link settings. Can someone help me figure it out please?

Here’s the link to my project:
LMS MARKDOWN PREVIEWER (codepen.io)

Much thanks!

I think the issue is with your ReactMarkdown component.

When I removed it then I was able to see your content on the page.

I think there is an issue with the import for reactmarkdown.

I don’t understand how people get this far without a working app. Test as you go.

You have a couple of problems. First, React is not imported. Go to Settings -> JS -> Add External Scripts/Pens. Type “react” into the search and select the react library and import it. But react-dom has to come after react, so either drag that down to the bottom or delete and re-import it.

When I’m having trouble, I like to simplify. Comment out your last line in your JS and add this:

const App = () => <h1>Howdy!</h1>
ReactDOM.render(<App />, document.getElementById("root"))

This just confirms that React is working now.

When I replace your last line, I notice that there are errors in the dev console:

So, there is something wrong with either your markdown import or how you are accessing it.

Also, as a sidenote, your might find working with codesandbox to be a better experience.

It comes with react templates so you don’t have to worry about any of this setup.
And it is super easy to add dependencies.

Hi Kevin
I did amend the JS settings but will try amending the markdown import and continue testing as I go. And let you know when I find the solution.

Thanks!
