I built a Full-Stack E-Commerce Boilerplate with Angular 19 Signals + Spring Boot 3.4 — here's what I learned

After months of building, I finally shipped KICKNOIR — a production-ready e-commerce boilerplate. Here's why I built it and what's inside. Why I built it Every boilerplate I found either used outdated stack versions or skipped the hard parts — auth, payments, CI/CD. So I built one that doesn't cut corners. Tech Stack Angular 19 with Signals API + Tailwind v4 Spring Boot 3.4 / Java 21 with stateless JWT auth Stripe checkout with LKR→USD conversion + Webhook fulfillment Docker Compose + GitHub Actions CI/CD Full Admin Dashboard The interesting parts The Signals implementation on the frontend eliminated a lot of the complexity I used to handle with services and RxJS. And wiring up Stripe Webhooks for order fulfillment was trickier than expected — happy to write a dedicated post on that if anyone's interested.
