I am setting up my ReactApp and just finished with it. So I wanted to make a settings class in a appsettings.ts file. So I can change some global variables easier.
But then all my issues started.
I know this problem is very common and there are tons of answers available but none of them have worked for me so far. I have searched through the internet to solve it but it still shows the same error.
This is the error I am getting:
ERROR in ../../../appsettings.ts
Module build failed (from ./node_modules/babel-loader/lib/index.js):
SyntaxError: [APP_DIR]\appsettings.ts: Unexpected token (2:11)
1 | export class APPSETTINGS {
> 2 | public static EMAIL_SENDER: string = "[email protected]";
| ^
3 | public static EMAIL_RECIPIENT: string = "[email protected]";
4 | public static YEAR: number = (new Date()).getFullYear();
5 | }

I got this error after I imported APPSETTINGS into my react app. If I delete the usage, then everything compiles fine, but with it, it just gives me this error
