In a detailed guide, a method is presented for creating a basic CRUD application using Spring Boot and Angular, underscoring the significance of feature flags for enhancing software deployment. The guide explains how to set up the development environment, create a backend using Spring Boot with a focus on REST endpoints, and integrate a front-end Angular application. It emphasizes the use of feature flags, enabled through the Split platform, to facilitate continuous deployment and safe feature releases, allowing developers to test in production and foster a culture of experimentation. The tutorial includes steps for incorporating feature flags to add a delete function to the app, demonstrating both backend and frontend integration, and highlights the benefits of feature flags in reducing release risk and supporting DevOps best practices. Additionally, resources for further learning about Spring Boot, Angular, and feature flag testing are suggested, along with an invitation to explore Split's feature management platform to enhance software development processes.
