February 2026 (2026-02) — Monthly development summary for deco-cx/deco. Focused on robustness, efficiency, and maintainability of the core caching and deployment workflows. Highlights include enhanced cache handling with Zstandard support and a safe fallback, runtime efficiency improvements via container tooling, and documentation improvements to guide future tooling integration. Key outcomes delivered across the Deco repo: - Cache system enhancements to support tar.zst caches and a download fallback, improving reliability and compatibility across diverse sites. - Docker images updated to include the Zstandard (zstd) library, enabling faster cache transfers and more efficient data handling at runtime. - Publish workflow clarified and documented with restored comments to signal potential Deno LSP integration, improving maintainability and signaling a future tooling roadmap. Business value and impact: - More robust and faster CI/CD cache behavior reduces build times and failure rates on heterogeneous environments. - Runtime efficiency gains from embedded zstd library translate to lower network usage and quicker cache warmups. - Clearer roadmap documentation reduces onboarding time for future tooling work and improves cross-team collaboration. Technologies/skills demonstrated: - Zstandard (zstd) integration for data compression - Cache management strategies supporting multiple archive formats (.tar, .tar.zst) - Docker image customization for runtime efficiency - GitHub Actions workflow maintenance and roadmap communication
