Type Alias JustProps<T>

JustProps<T>: Exclude<Pick<T, PropNames<T>>, never>

Create a new type from an object type extracting just properties, not methods.

Type Parameters

  • T

See

JustMethods for extract just methods

Example

  import {JustProps} from 'type-fest';
  interface Foo {
    a: string;
    b: number;
    c(): string;
    d(x: string): string;
  }
  const foo: JustProps<Foo> = {a: 'a', b: 1};

Note: Exclude<..., never> is used to force TypeScript to report final type as an object, not a type helper call
