As I see, decorators usually can be used with classes and methods inside classes. Is there a way to use decorators with regular functions like in code below:
@myDecorator()
function someFunction() {
// do something
}
someFunction(); // running the function with the decorator.
Not with the current proposal. Decorating stand-alone functions, object initializers and their contents, or other things may well be follow-on proposals, but the current proposal only allows decorating classes and their contents.
Decorators are not supported on functions as per the current proposal
You can acrive a similar result using a simple function call:
function myDecorator<Args extends any[], R>(fn: (...a: Args)=> R): (...a:Args) =>R {
return function (...a: Args) {
console.log("Calling");
return fn(...a);
}
}
const someFunction = myDecorator(function () {
console.log("Call");
});
someFunction();
