打字稿，是否可以在没有某种类型的情况下扩展接口？

Question

import React from "react";

interface a_to_e {
  a?: string;
  b?: string;
  c?: string;
  d?: string;
  e?: string;
}

interface a_to_e_without_c extends a_to_e {
  // I'd like to implement a~e without c
}

function Child(props: a_to_e_without_c) {
  return (
    <>
      <div>child</div>
    </>
  );
}

function App() {
  return (
    <>
      <Child c="I'd like to throw compile error," />
    </>
  );
}

export default App;

Is is possible to extend interface in typescript except some special type?

Of course it can be implemented by making custom exception,

but I'd like to throw compile error ,

when some of my co-worker use Child component with property c.

Is it possible?

Answer 1

You can use Omit utility of typescript

example:

interface a {
  a: string,
  b: string,
  c: string
}

type without_c = Omit<a, "c">;

const variable_with_c: without_c = {
  a: "a",
  b: "b",
  c: "c" //compile error
}
