Currently, I am in the process of building an Express.js application using TypeScript. By installing @types and referring to various resources, I managed to create a functional program. However, my main query revolves around locating comprehensive documentation for TypeScript types related to JavaScript libraries.
For instance, I have grasped from examples the necessity to import Router, Response, and Request in the following manner. Nonetheless, I am eager to discover an official source that outlines the classes and interfaces made available by the library through @types.
import { Router, Response, Request } from 'express';
