Full Stack App — Node.js + Vue 3

Wanted to strengthen knowledge in technologies different from Ruby on Rails — specifically building a complete REST API backend with Node.js/Express and a reactive frontend with Vue 3.

Built a full-stack CRUD application: Express.js REST API handling authentication, data operations, and business logic, with a Vue 3 SPA consuming the API. MySQL as the relational database.

Decoupled frontend/backend: Express REST API with JWT auth and MySQL for persistence. Vue 3 SPA with the Composition API consuming the API. Each service runs independently.

Key Challenges

• Structuring an Express app with clean separation of routes, controllers, and services
• Handling JWT authentication state reactively in Vue 3 with the Composition API
• Managing MySQL connections efficiently in a Node.js environment
