Which core capabilities belong in a gatsby competency checklist?

The core capabilities in a gatsby competency checklist include React proficiency, GraphQL fluency, performance engineering, and production operations.

• React component architecture, hooks, and state patterns
• GraphQL schema literacy and Gatsby data layer mastery
• Performance budgets, image optimization, and bundle control
• Build pipelines, caching strategy, and release hygiene

1. Gatsby fundamentals

• Core Gatsby lifecycle APIs, file-based routing, and plugin ecosystem fit within modern JAMstack delivery.
• React alignment, SSR/SSG/DSG modes, and environment configuration anchor predictable builds.
• Clear mental model enables stable page generation and consistent dev experience across teams.
• Misalignment here introduces flaky builds, routing regressions, and capacity bottlenecks.
• Apply starter baselines, incremental refactors, and typed components to reduce defect rates.
• Validate via repository walkthroughs, scaffold tasks, and PRs that extend plugins safely.

2. GraphQL data sourcing

• Source plugins, node creation, and schema customization drive resilient content flows.
• Pagination, fragments, and field resolvers structure maintainable queries at scale.
• Strong data modeling prevents over-fetching, waterfall requests, and brittle templates.
• Robust sourcing improves cache reuse, build speed, and runtime stability.
• Compose typed queries, enforce naming conventions, and centralize fragments for reuse.
• Add query cost guards, null-safety checks, and telemetry on resolver timing.

3. Performance and Lighthouse optimization

• Page speed centers on bundle size, network strategy, and render efficiency.
• Core Web Vitals targets align engineering effort with user and SEO outcomes.
• Faster pages lift engagement, conversion, and crawl efficiency across releases.
• Regressions inflate infra spend and undermine acquisition performance.
• Enforce budgets, code-split routes, and prefer gatsby-plugin-image with responsive variants.
• Track LCP/CLS/INP, prefetch critical paths, and gate merges on thresholds.

4. Rendering modes (SSG, DSG, SSR)

• Static generation, deferred static generation, and server rendering serve distinct delivery needs.
• Mode selection depends on content freshness, scale, and personalization scope.
• Correct alignment reduces origin load, build time, and cache churn.
• Mismatch raises TTFB, invalidates caches, and complicates deployments.
• Classify routes by volatility, audience, and data dependencies before picking a mode.
