## Overview

This is a command-line backend project scaffold generator. A user supplies a project name; the CLI creates the project directory and standard source layout, asks which backend features to include, then configures the package and installs selected dependencies. Optional database tooling and opening the project in VS Code are handled during installation. The README is empty, so capabilities and wiring here are based on the sampled source files.

Main entry points: [`lib/index.js`](https://github.com/gnelshahnazaryan/create-backend-app/blob/main/lib/index.js) (Project workflow), [`lib/installer.js`](https://github.com/gnelshahnazaryan/create-backend-app/blob/main/lib/installer.js) (Dependency installer), [`lib/prompts.js`](https://github.com/gnelshahnazaryan/create-backend-app/blob/main/lib/prompts.js) (Feature prompts), [`bin/create-backend-app.js`](https://github.com/gnelshahnazaryan/create-backend-app/blob/main/bin/create-backend-app.js) (CLI command)
