namespace (typescript)

方法は2つ

namespaceを使う

code:ts

namespace Foo {

export type Bar = string;

}

import *を使う

code:Foo.ts

export type Bar = string;

code:ts

import type * as Foo from "./Foo";

Effect-TSでは、index.tsでexport * asを使ってる

code:effect/src/index.ts

export * as Either from "./Either.js"

code:effect/src/Either.ts

export type Either<A, E = never> = Left<E, A> | Right<E, A>

export const TypeId: unique symbol = either.TypeId
