What is the process for combining two interface declarations into a single interface?

I have a question regarding organizing the properties of an interface:

export interface IInvoicesData {
    invoice: IInvoice;
    invoiceWithTotals: IInvoice & IInvoiceTotals;
}

Currently, everything is functioning smoothly and I am able to consolidate properties from both IInvoice and IInvoiceTotals interfaces into the invoiceWithTotals property.

However, I am interested in separating the declaration IInvoice & IInvoiceTotals into its own interface. Is there a way for me to achieve this without using extends, and instead replace IInvoice & IInvoiceTotals with something like IInvoiceWithTotals?

typescript

Answer №1

interface IInvoiceWithTotals extends IInvoice & IInvoiceTotals;

This solution appears to be functioning correctly.
