Covers project setup with Maven and pnpm, Vite integration for CSS/JS asset bundling with hashed filenames, Spring Boot auto-configuration using @AutoConfiguration and @ConfigurationProperties, a ViteManifestParser for reading build manifests, and a TclAssets bean that switches between dev and production asset URLs. Also demonstrates live reload by running dual Vite dev servers (one for the library, one for the consuming app), and shows how to wire the library into a sample Spring Boot application using a Thymeleaf layout fragment. ## Full article daily.dev links to this article rather than hosting it.
