Type error: 'popup.ts' cannot be compiled under '--isolatedModules' because it is considered a global script file. Add an import, export, or an empty 'export {}' statement to make it a module.
If you are a seasoned developer who has encountered the type error 'popup.ts' cannot be compiled under '--isolatedModules' and you want to fix it without diving too deep into the issue, you've come to the right place.
In this article, we will provide you with a simple solution to resolve this error.

Understanding the Error

Let's start by understanding the error message.
The error message states that the file 'popup.ts' cannot be compiled under '--isolatedModules'.
This error typically occurs when the TypeScript compiler encounters a file that it considers to be a global script file, meaning it does not have any imports, exports, or an empty 'export {}' statement.
To fix this error, we need to transform the 'popup.ts' file into a module by adding an import, export, or an empty 'export {}' statement.


To fix this error, follow these steps:
  1. Open the 'popup.ts' file in your code editor.
  1. Add an empty 'export {}' statement at the top of the file. This statement tells TypeScript that the file is a module.
export {}
  1. Save the file and try compiling it again. The type error should now be resolved.

Code Example

Here's an example of how your 'popup.ts' file should look after adding the empty 'export {}' statement:
export {} // Your code here


In this article, we have discussed how to fix the type error 'popup.ts' cannot be compiled under '--isolatedModules' by adding an empty 'export {}' statement to the file.
By following the simple steps provided, you can easily resolve this error and continue with your development process.
Remember, it's important to understand the error message and the solution before implementing it.
If you encounter any further issues or have any questions, don't hesitate to seek further guidance from the TypeScript documentation or community.
Happy coding!
