Standards are crucial for achieving predictability and maintainability in a code base. The Vue.js community provides several sources of standards, including the Vue.js Style Guide and official libraries. Personal and team-wide standards can complement community-wide ones. Alternative component structures, like an almost flat structure, can work well for large apps. Adopting a standardized route naming convention can make routes more predictable. Miscellaneous tips include wrapping third-party libraries, creating SDKs for APIs, and auto-registering components globally. Thorough testing is important, and Vue School offers various services and courses for becoming an expert in Vue.js.
