Treffer: Building Effective and Responsive Search Interfaces with Angular for Libraries.

Digital repositories are an essential aspect of modern library services, and in most cases, traditional interfaces cannot provide effective information retrieval. This study introduces an Angular-based search form implemented in DSpace 7 as a prototype approach to enhancing discovery, interoperability, and user experience. The framework was developed on an Ubuntu system with DSpace 7 CRIS, supported by Apache Tomcat, Solr, PostgreSQL, Yarn, npm, and nvm to ensure flexibility in backend and frontend adaptation. The Angular interface was evaluated for metadata management, interaction with repositories such as PubMed and ArXiv, and compliance with REST, OAI-PMH, and SWORD APIs. Results showed that the interface enables single-box multilingual searches, efficient metadata management, simple integration, and advanced digital capabilities such as metadata import/export and server health checks. Built-in accessibility features across the backend, frontend, and OAI-PMH endpoints further simplified repository management. Overall, the study demonstrates how DSpace CRIS and Angular Avant Garde can modernize digital libraries through a responsive, interoperable, and discoverycentered architecture, providing valuable insights for researchers, librarians, and academic communities in developing next-generation institutional repositories.
