Express API — TypeScript Project Setup

Problem/Feature Description

A startup is building a REST API for a task management application using Express and TypeScript. They need the project scaffolded from scratch with proper TypeScript configuration, project structure, and build tooling. The API will have endpoints for managing tasks (CRUD) and users (registration, login).

The team wants strict type safety, clean imports, and a project layout that will scale as the codebase grows. They plan to add tests later and want the structure to support that.

Output Specification

Produce a project structure with the following files:

• package.json — with dependencies and scripts (build, dev, start, typecheck, lint, test)
• tsconfig.json — strict TypeScript configuration with path aliases
• .gitignore — proper ignores for a TypeScript/Node project
• eslint.config.js — ESLint with typescript-eslint
• src/index.ts — Express app entry point
• src/routes/tasks.ts — Task CRUD route handlers
• src/routes/users.ts — User route handlers
• src/services/taskService.ts — Task business logic
• src/services/userService.ts — User business logic
• src/types/index.ts — Shared type definitions (Task, User, API request/response types)
• src/lib/config.ts — Application configuration

The application does not need to connect to a real database — use in-memory stores. Focus on project structure, tsconfig setup, and TypeScript patterns rather than complete implementation.
