singleton-decorator

An ES7 decorator that adds singleton behavior to classes. Very tiny and easy-to-use.

Usage

Decorator accepts no arguments. The class will be decorated with the "implicit" and "explicit" styles together. You can treat the class as if it weren't a singleton but only one instance will ever be created:

import singleton from 'singleton-decorator';
 
@singleton
class Foo {
}
 
let a = new Foo(),
    b = new Foo(),
    c = Foo();
    d = Foo.getInstance();
 
// a === b === c === d
