Those posts teach built-in widgets, Session State/cache, ordinary Streamlit app tests, or API/frontend separation. This article instead centers the Python-to-JavaScript component boundary, state versus trigger values, programmatic synchronization, style isolation, package manifests, frontend tests, and wheel smoke checks. source check: Reviewed against the official Streamlit Custom Components v2 overview, registration, mounting, state/trigger, bidirectional communication, package-based component, and API reference pages on 2026-10-07. The article uses the recommended v2 API introduced for modern components, not the legacy iframe-based v1 API. ---> <p> <figure> <img class="my-0 rounded-md" loading="lazy" alt="featured" src="./featured.png" /> </figure> </p>
