## Overview

Journal App is a full-stack personal journaling product. Users register or log in, then access a dashboard to view and manage their journal entries through authenticated backend APIs backed by MongoDB. The sampled backend code confirms signup/login, JWT generation, user-scoped entry operations, and persistence. Frontend page-to-API wiring and several backend integrations are not shown in the excerpts, so those relationships are omitted.
