Currently, this construct is being utilized to create a global LOG:
declare global {
let LOG: Logger;
}
// eslint-disable-next-line @typescript-eslint/no-namespace
declare namespace globalThis {
let LOG: Logger;
}
globalThis.LOG = new Logger();
It functions as intended, but why do I have to declare it twice?
Extra query: What can be done to optimize this process and improve efficiency?
The reason why the global namespace interface differs from that of globalThis is because the latter is a subset of the former. This means that there can be global variables that exist outside of the properties of the global object, which are created using global-scope let, const, and class. TypeScript clearly defines these distinctions. It is possible that if both had been established simultaneously, the global namespace could have intersected with the interface of globalThis. However, since the definition of globalThis is relatively new, or due to other factors, this approach was not taken.
It turns out that the solution was to change let to var:
declare global {
// eslint-disable-next-line no-var
var LOG: Logger;
}
global.LOG = new Logger();
