VLifeWrapper (VLW)

VLW is a multi-part system with a Node/Express REST API backed by PostgreSQL and a Next.js frontend. The API implements OAuth 2.0 flows with scope-based authorization and supports Google OAuth and Sign in with Apple using Passport. It includes OTP-based verification for login and password reset, file upload support, and Swagger documentation. Docker Compose is used for local orchestration (API + Postgres). The frontend is built with Next.js and includes dashboards and data visualization (Chart.js/ApexCharts), state management (Redux Toolkit + persistence), and optional real-time capabilities via Socket.IO client, with deployment scripts for AWS S3 + CloudFront and EC2.

Challenges

•Migrating to OAuth 2.0 flows with scope-based authorization
•Supporting multiple identity providers (Google + Apple) alongside OTP flows
•Shipping a deployable architecture with Docker and repeatable deployment scripts

Solutions

•Implemented OAuth 2.0 middleware + Passport strategies for Google/Apple and scope enforcement
•Built OTP-based verification flows for login and password reset with email delivery
•Added Docker Compose for local environment (Postgres + API) and production-friendly config patterns

Impact

✓

Secure, standards-based auth architecture ready for production requirements

✓

Clear separation of concerns between API services and frontend dashboards

✓

Repeatable local + deployment workflows to support ongoing development
