Divide the enhanced document into sections using TypeScript

In my project, I am working with Material UI and TypeScript. I have noticed that I need to declare the Theme interface and ThemeOptions in the same file for it to work properly. Is there a more efficient way to separate these declarations from the main tsx file?

import React from "react";
import ReactDOM from "react-dom";
import { createTheme } from "@mui/material";
import { orange } from "@mui/material/colors";

declare module "@mui/material/styles" {
  interface Theme {
    status: {
      danger: string;
    };
  }
  
  interface ThemeOptions {
    status?: {
      danger?: string;
    };
  }
}

const theme = createTheme({
  status: {
    danger: orange[500],
  },
});

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById("root")
);

To start customizing your project, navigate to the specific directory within your project and create a [name].d.ts file (you can choose any name). Populate it with the following code:

import { ThemeOptions } from "@mui/material/styles"; // It is highly recommended to use this path.
import { Theme } from "@mui/material/styles"; // It is highly recommended to use this path.

declare module "@mui/material/styles" {
  interface Theme {
    status: {
      danger: string;
    };
  }
  interface ThemeOptions {
    status?: {
      danger?: string;
    };
  }
}

Once you have done this, there is no need to explicitly import the file anywhere. The TypeScript project will automatically incorporate the new properties into both Theme and ThemeOptions.

Keep in mind that ThemeOptions is meant for the createTheme function, while Theme is designed for use with functions like useTheme or makeStyles. Ideally, these files should share the same properties, with all of them being optional in the Theme file.
