window object in NodeJS of SSR got both 'not defined' or 'already been declared' - node.js

Question

I am migrating an Angular 6 project to Angular Universal project(SSR). In my project, I need to access window object in order to get "navigator", "location", etc... I am using the following method to polyfill window in Server side. But it is not working.
try {
console.log(window);
} catch (window) {
console.log('Server side window.');
window = {
location: {
replace: () => {},
protocol: 'https'
},
navigator: {
userAgent: '',
appVersion: ''
},
scrollTo: () => {},
open: () => {},
localStorage: {}
};
console.log('Server side window.', window);
}
What is the best way to handle the window object properly on the server side for the server-side rendering web site? I got following confusion errors. It said 'window is not defined' or 'has been declared'. How to use window object in NodeJS?
> console.log(window);
ReferenceError: window is not defined
> let window = 1
SyntaxError: Identifier 'window' has already been declared

Answer 1

The problem with this piece of code is that window is specified as exception identifier in try..catch, basically:
try {
console.log(window);
} catch (window) {
// window instanceof ReferenceError
window = {...};
// window is redefined in this block scope
}
This will work in loose mode:
try {
console.log(window);
} catch (err) {
window = {...};
}
But will result in another ReferenceError in strict mode. It should be instead:
try {
console.log(window);
} catch (err) {
global.window = {...};
}
And a proper way to detect window is:
if (typeof window === 'undefined') {
global.window = {...};
}
This code is limited to browser and Node.js; it will result in an error in a worker.
