How to create a singleton service in Aurelia?

Question

I\'m pretty new to Aurelia (only been using it a few days) and I love it!

I know how to make a service with Aurelia, but how can I make that service a singleton that

Answer 1

So I realized I was thinking about this too hard. I was trying to depend on the framework (Aurelia) to do all the work, but actually it was a simple ES6 class change that makes it an instance.

let instance = null;

export class SingletonService {

	constructor() {
		if(!instance) {
			instance = this;
		}

		return instance;
	}
}

Answer 2

Just inject it

By default, the DI container assumes that everything is a singleton instance; one instance for the app. However, you can use a registration decorator to change this.
