Cannot destructure property ‘basename’ of ‘react__webpack_imported_module_0__.usecontext(…)’ as it is null.

by

This error message is related to React and it occurs when you try to destructure a property from a null value using the ‘useContext’ hook.

The error message “cannot destructure property ‘basename’ of ‘react__webpack_imported_module_0__.usecontext(…)’ as it is null.” means that the value you are trying to destructure the ‘basename’ property from is null, so it cannot be destructured.

To fix this issue, you need to make sure that the value passed to the ‘useContext’ hook is not null before trying to destructure its properties. This can be done by either checking if the value is null or using a default value as a fallback.

Here is an example that illustrates the error and how to fix it: 


import React, { useContext } from 'react';

const MyContext = React.createContext(null);

const MyComponent = () => {
  const contextValue = useContext(MyContext);

  // Trying to destructure the 'basename' property from a null value
  const { basename } = contextValue;
  
  return (
    <div>
      <h2>{basename}</h2>
      // Rest of the component
    </div>
  );
};

export default MyComponent;

In the above example, if the ‘contextValue’ is null, then trying to destructure the ‘basename’ property from it will throw an error.

To fix this, you can provide a default value for the ‘contextValue’: 


const contextValue = useContext(MyContext) || {}; // set default value to an empty object

By providing a default value, even if the ‘contextValue’ is null, it will fallback to an empty object and the destructuring will not throw an error.
