QUESTION
I'm using Showdown module to obtain HTML from markdown. I want to display the generated HTML in my React component. My converter is working fine generating the HTML:
Type your markdown bounty here…
But I get this error message: Uncaught Error: Target container is not a DOM element.
Is there another/better way to display the generated HTML? Can anyone point what I'm doing wrong?
ANSWER
Answered 2022-Apr-08 at 23:47That error is thrown because you are trying to get a reference to a DOM node while it has still to be rendered on DOM itself. You could solve it by calling ReactDOM.render inside a useEffect with an empty deps array [], this way it would be executed after the first render, but you will notice that it would anyway not work as expected, since it will render a string representing HTML code, it won't parse it! ReactDOM.render is used to attach JSX code to a DOM node, while you are trying to pass an HTML string ( that' s what converter.makeHtml() returns ). So it would never work.
A working approach would be:
- Convert Markdown to HTML
- Transpile HTML/JSX to React first level API
- Parse the transpiled code
- Execute it as real JSX code
This is an example :

import { Observer, useLocalObservable } from 'mobx-react-lite';
function App() {
const { count, decrement, increment } = useLocalObservable(() => ({
count: 0,
increment() { this.count++ },
decrement() { this.count-- },
}));
return (
{() => ({count})}
{ decrement() }} >decrement
{ increment() }} >increment
);
}
ANSWER
Answered 2022-Mar-24 at 10:21The Observer tracks all the observable data that is dereferenced inside of it and re-renders when that observable data changes. When you dereference count from your observable outside of the Observer it is just a regular JavaScript number from that point onwards, so there is nothing for Observer to track.
You could instead dereference it inside the Observer and it will work:

Answered 2022-Mar-03 at 19:14The only overt issue I see with your code is that you are directly invoking your React components instead of rendering them as JSX for React to handle and manage the component lifecycle of.

QUESTION
I am trying to create a recursive component that stores it's state in a mobx observable object.
For some peculiar reason, if the observable links another observable in it's properties, the observer hoc from mobx-react-lite does not trigger re-render, when the observable state changes.
Here is the example, where the elements, that are more than 1 deep, are not re-rendered, when the observable state changes.
...ANSWER
Answered 2022-Jan-03 at 19:59You are exporting observer component (export default memo(observer(NodeView));), but inside NodeView itself you are using non-observer NodeView
You need to wrap it with observer right away, so recursive version would be reactive too:

I am trying to do an onClick event in a react Modal. When I fire the onClick event I would like for it to issue a component form. The onClick event seems to work, but when it renders the component it is throwing the following error.
TypeError: Cannot read properties of undefined (reading 'toString')
Which seems to be coming from the following line in the Component Form
const page = parseInt(router.query.page.toString());
I have placed the code below for inspection
