Getting undefined when using import() to dynamically import an instantiated class object

If you are working with TypeScript and using the import() function to dynamically import modules, you may encounter a situation where you get undefined when trying to access an instantiated class object. This can be frustrating, but there are a few solutions you can try to resolve this issue.

Solution 1: Using `await` with `import()`

One possible solution is to use the await keyword when calling the import() function. This ensures that the module is fully loaded before accessing the instantiated class object. Here’s an example:


async function importModule() {
  const module = await import('./path/to/module');
  const instance = new module.ClassName();
  // Access the instantiated class object
}

By using await with import(), you can ensure that the module is loaded and the instantiated class object is available for use.

Solution 2: Using `then()` with `import()`

Another solution is to use the then() method instead of await. This allows you to handle the promise returned by import() and access the instantiated class object once the module is loaded. Here’s an example:


import('./path/to/module')
  .then((module) => {
    const instance = new module.ClassName();
    // Access the instantiated class object
  });

Using then() allows you to handle the promise returned by import() and access the instantiated class object within the callback function.

These are two possible solutions to the issue of getting undefined when using import() to dynamically import an instantiated class object in TypeScript. Try them out and see which one works best for your specific use case.
