React website only rendering component after changing detail in app.tsx and saving but disappears upon webpage reload

If you are experiencing a situation where your React website only renders a component after changing a detail in the app.tsx file and saving, but the component disappears upon webpage reload, you are not alone. This issue can be frustrating, but fortunately, there are a few possible solutions to consider.

Solution 1: Check for Errors in the Console

One common reason for components disappearing upon webpage reload is the presence of errors in the console. It’s essential to check the console for any error messages that could be causing the issue. These errors might be related to syntax errors, missing imports, or other issues in your code.

To check for errors in the console, open your browser’s developer tools (usually by pressing F12), navigate to the “Console” tab, and look for any error messages. If you find any errors, address them accordingly, and try reloading the webpage to see if the component renders correctly.

Solution 2: Ensure Proper Component Rendering

Another possible reason for the component disappearing upon webpage reload is incorrect component rendering. Make sure that the component is being rendered correctly in your app.tsx file. Check if the component is added to the JSX code and properly nested within other components.

Here is an example of how to render a component in app.tsx:

{`
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

ReactDOM.render(
  
    
  ,
  document.getElementById('root')
);
`}

Ensure that your component is added within the tags or any other relevant component tags in your specific case.

Solution 3: Check for State or Prop Changes

If your component relies on state or props, it’s crucial to check if there are any changes in these values that could be causing the disappearance upon webpage reload. Ensure that the state or prop values are correctly set and passed to the component.

For example, if your component relies on state, make sure you are updating the state correctly and triggering a re-render when necessary. If your component relies on props, ensure that the props are being passed correctly from the parent component.

Here is an example of how to update state in a functional component:

{`
import React, { useState } from 'react';

const MyComponent = () => {
  const [myState, setMyState] = useState('initialValue');

  const updateState = () => {
    setMyState('updatedValue');
  };

  return (
    
      {myState}
      
    
  );
};

export default MyComponent;
`}

Ensure that you are correctly updating the state and passing the updated value to the component.

By following these solutions, you should be able to resolve the issue of your React website only rendering a component after changing a detail in app.tsx and saving, but it disappearing upon webpage reload. Remember to check for errors in the console, ensure proper component rendering, and verify state or prop changes.

Happy coding!
