How to use internal APIs for custom commands

[NoelDeMartin]

I'm going through the guide to make Custom Queries, and there are a couple of examples using internal APIs like cy.state.

However, since I am writing my code in TypeScript, I can't use the internal types. Is there a know workaround for this? Like installing a separate @types package or something?

Hey @NoelDeMartin, did you find any solution around this ?

I didn't find any decent workaround, so I'm just manually declaring the types I'm using :/. For example, to declare cy.state I added this in my codebase:

declare global {
    namespace Cypress {
        interface Chainable {
            state(type: 'current'): Cypress.Command;
        }
    }
}
