A Vue component that lazily renders Mermaid diagrams using IntersectionObserver. It defers diagram rendering until the element is visible in the viewport, improving initial page load performance. The component is self-contained and can be extracted into any VuePress or Vue-based documentation site that uses Mermaid.

Client-side chunk load error recovery logic. On chunk loading failure, it stores a reload key in sessionStorage and triggers a page reload. This pattern prevents broken navigation in production builds and can be reused in any VuePress or Vite-based application to handle dynamic import failures gracefully.

A Vue component that implements a content unlock mechanism requiring QR code scanning and verification code input. It manipulates the DOM to reveal hidden content. This pattern is reusable for any documentation site that needs to gate premium content behind a simple verification flow.

A Node.js script that parses a sitemap, extracts content from HTML pages using cheerio, and uploads hierarchical records to Algolia DocSearch. It includes batch upload, custom ranking, and faceting configuration. While site-specific (hardcoded domain), the pattern of sitemap-driven indexing with cheerio extraction is reusable for any static site needing Algolia search.
