Lifetimes

const Counter = createToken<{ id: number }>('Counter');
let nextId = 0;

container.factory(Counter, () => ({ id: ++nextId }));

const singletonA = await container.resolve(Counter);
const singletonB = await container.resolve(Counter);

singleton caches the first result, transient returns a new value every time, and scoped caches once per child container.

container.factory(Counter, () => ({ id: ++nextId }), { lifetime: 'transient' });
container.factory(Counter, () => ({ id: ++nextId }), { lifetime: 'scoped' });
