            That 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 :

            The 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:

            You are calling setVisible directly in your Mask component, which causes a re-render, which causes setVisible to be called again, and the infinite loop continues.

            You could make it so that you only update the state when store.isLoading actually changes with the help of useEffect:

            Issue

            The 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.

            Your function is losing context (this), you need to read about it to understand how it works. You destructured this function from the store and it is not bound to it anymore.

            The most common way is to define all actions as arrow functions, like that:

            Answered 2022-Feb-04 at 22:37

            You need to wrap every component that uses any observable values with observer decorator, like you did with an App. But in case of App it's actually useless because you are not using observable values there. So just wrap other components and it should work fine.

            As for this line textFromFirstStore = testStoreFirst.textForSecondTestStore it won't work like you expected because you just assigned value of testStoreFirst.textForSecondTestStore to textFromFirstStore and that's it.

            To make such value reactive you need to use computed value. To make computed you just need to setup a getter function, like that:
