Dropwizard is a Java framework for developing ops-friendly, high-performance, painless RESTful web services. I've presented this simple & light-weight framework (with an example project) on 10th of June. Agenda: Presentation (20 minutes): - Definition & History (What is Dropwizard, versions, first commit etc.) - Libraries (Built-in libraries, what we use these for etc.) - User Manual (Project configuration, documentation, getting started etc.) - Performance (Comparison with other frameworks) - Versus (Dropwizard vs Springboot on technical terms) I've prepared a sample Brown Bag Seminars (BBS) application to demonstrate features of Dropwizard (with MongoDB integration). Sample Project & Code Review (40 minutes): - Project configuration - Resource - Representations - Views - Health checks - Metrics - Tests
