            Unable to display generated HTML ,from Showdown plugin, in React component
            Asked 2022-Apr-08 at 23:47

            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?



            Answered 2022-Apr-08 at 23:47

            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 :



            Observer not working with useLocalObservable
            Asked 2022-Mar-24 at 10:21
            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

            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:



            Use mobx and react get an error: Too many re-renders. React limits the number of renders to prevent an infinite loop
            Asked 2022-Mar-10 at 08:32

            In my mind, I want use mobx to save a state named mask, when I use axios, this state will be true and when i finshed call, this state will be false, below is my code




            Answered 2022-Mar-10 at 08:32

            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:

            I've created dynamic routing on my site, which changes when a user login successfully. The fact of logging I keep in global state, which observers by mobx. When the user login successfully, routes changes too, and it works correctly, but in the console, there is the next problem: Error

            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.




            How use Mobx 6 storage with React 17?
            Asked 2022-Feb-04 at 22:37

            I'm completely confused with the rules of mobX - react . Some methods in another project work, but not in this test.

            Below is the code of my components from the test application




            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:

            I want to restart a circular progress bar after 30 seconds
            Asked 2021-Dec-22 at 23:57
            const useProgress = (maxTimeInSeconds = 30) => {
                const [elapsedTime, setElapsedTime] = useState(0);
                const [progress, setProgress] = useState(0);
                useEffect(() => {
                  const intervalId = setInterval((callback) => {
                    if (progress < 1) {
                      setElapsedTime((t) => t + 1);
                  }, 1000);
                  return () => clearInterval(intervalId);
                }, []);
                useEffect(() => {
                  setProgress(elapsedTime / maxTimeInSeconds);
                }, [elapsedTime]);
                return progress;
              const progress = useProgress();


            Answered 2021-Dec-22 at 23:57

            progress does not need to be a state atom since it's always unambiguously calculable from the elapsed time and max time.

            Using the modulo (remainder) operator you can have the observed progress always loop back to 0 after the maximum time.

            Install mobx-react

            Or CDN: (UMD namespace: mobxReact). This package provides the bindings for MobX and React. See the official documentation for how to get started. For greenfield projects you might want to consider to use mobx-react-lite, if you intend to only use function based components. React.createContext can be used to pass stores around.


            Please check for the general documentation. The documentation below highlights some specifics. Function (and decorator) that converts a React component definition, React component class, or stand-alone render function, into a reactive component. A converted component will track which observables are used by its effective render and automatically re-render the component when one of these values changes. React.memo is automatically applied to functional components provided to observer. observer does not accept a functional component already wrapped in React.memo, or an observer, in order to avoid consequences that might arise as a result of wrapping it twice. When using component classes, this.props and this.state will be made observables, so the component will react to all changes in props and state that are used by render. shouldComponentUpdate is not supported. As such, it is recommended that class components extend React.PureComponent. The observer will automatically patch non-pure class components with an internal implementation of React.PureComponent if necessary. See the MobX documentation for more details. Observer is a React component, which applies observer to an anonymous region in your component. It takes as children a single, argumentless function which should return exactly one React component. The rendering in the function will be tracked and automatically re-rendered when needed. This can come in handy when needing to pass render function to external components (for example the React Native listview), or if you dislike the observer decorator / function. In case you are a fan of render props, you can use that instead of children. Be advised, that you cannot use both approaches at once, children have a precedence. Example.
