Library Management System

Abstract

1. Introduction

The client is a standalone Angular SPA; the server is an Express + TypeScript API. The two talk over HTTP only — there's no server-side rendering or shared process. The server owns all MongoDB access; embedding generation for search is a pluggable provider selected at runtime (see AGENTS.md).

A full-stack library app — browse a catalog, borrow and reserve books, leave reviews — built on the MEAN stack (MongoDB, Express, Angular, Node.js). It's the sample app used in MongoDB Developer Days hands-on labs, so the codebase intentionally shows off several MongoDB schema design patterns and MongoDB Search / MongoDB Vector Search side by side, not just CRUD.

2. Objective

Sample library system used in the hands-on labs during Developer Days

This project demonstrates how TypeScript, Angular, Express can be applied to a real-world Full Stack Web Development problem.

3. Key Features / Modules

• Browse, add, edit, and delete books, each with authors, genres, and free-form
• Borrow and return books, with due dates and history, or reserve a book that's
• Leave and read reviews per book
• Role-based access: admin-only routes for managing inventory and borrow records
• Workshop labs for full-text and vector search over the book catalog, including
