February 2025 performance summary: Focused on modernizing the docs build and preview experience, expanding design capabilities, and hardening deployment workflows across the Elastic docs ecosystem. Key groundwork included establishing ParcelJS as the build tool for elastic/docs-builder, enabling faster and more deterministic asset bundling. We introduced a redesign feature flag and began enabling the new design by default, with an updated header and breadcrumbs to improve navigation. Enhancements and automation expanded the scope of preview and CI/CD: safe preview deployment workflows were implemented, with performance and reliability optimizations, and path-pattern input was added to the preview-build workflow. A docs preview setup guide was added to accelerate onboarding. In parallel, we extended documentation workflows to support extensionless URLs and pretty URLs, along with comprehensive content rendering improvements (code blocks, admonitions, headings, and lists) and UI styling updates (dropdowns, tables, and navigation components). Quality and governance improvements were accelerated via automation: AsciiDoc freeze warnings and automated PR feedback were implemented across multiple repos using reusable workflows from docs-builder, reducing manual review time and increasing content consistency. Reliability fixes targeted previews and navigation, including deploy/PR preview fixes, relative links, and ToC navigation, and performance enhancements to minimize layout shifts during page load. Overall impact: faster, safer docs builds and previews, improved user experience and onboarding, and stronger engineering discipline across the docs stack. Technologies demonstrated: ParcelJS, feature flags, GitHub Actions, changed-files workflows, and front-end design/system modernization.
