### Converting TypeScript Class to Effect Service with Runtime Configuration

export class PricingService implements Pricing {
    constructor(
        private readonly rules: Rule[],
        private readonly duration: Duration,
        private readonly vatComputation: VATComputation,
    ) {}

    discountedPrice(): number {
      return 0
    }
}

class PricingServiceConfig extends Effect.Service<PricingServiceConfig>()("PricingServiceConfig", {
    succeed: {
        rules: someRules,
        duration: someDuration,
        vatComputation: someVATComputation,
    }
}){}

export class PricingService extends Effect.Service<PricingService>()("PricingService", {
    dependencies: [PricingServiceConfig.Default],
    effect: Effect.gen(function*(){
        const config = yield* PricingServiceConfig
    })
}){}

const getSpacePricing = (spaceId: SpaceID) => {
        const space = getSpace(spaceId)
        if (space.type === 'meeting') {
                return new MeetingPricing(space.rules, createVAT('default'))
        } else {
                return new BasicPricing(space.rules, createVAT('reduced'))
        }
}

const createInvoice = (bookingId: BookingID) => {
        const booking = getBooking(bookingId)
        const spacePricing = getSpacePricing(booking.spaceId)

        const totalPrice = spacePricing.getTotal()
        const vatPrice = spacePricing.getVat()
        const extraPrice = spacePricing.getExtra()
}
