I have two separate typedef files.

typedefFirst.js

/**
 * ControllerResponse
 * @typedef {Object} ControllerResponse
 * @property {Number} statusCode
 * @property {{ data: (Object | Array )}} body
 */

/**
 * ExpressRouter
 * @typedef {import('express').Router} ExpressRouter
 */

typedefSecond.js

/**
 * Context
 * @typedef {Object} Context
 * @property {String} userId
 * @property {String} role
 * @property {String} accessToken
 */

/**
 * ExpressRequest
 * @typedef {import('express').Request} ExpressRequest
 */

I want to aggregate all types and define all the types in one file i.e. typedefFirst.js.

I tried export.unused = {} in typedefSecond.js and tried below in typedefFirst.js,

/**
 * @typedef {import('./typedefSecond.js')}
 */

But it is not working.

How can I merge both typedef files?
