Svelte β€” Advanced: rendering, resources and release evidence

Review SSR, caching, security, testing and deployment with precise version assumptions.

6 lessons Β· No account required

What you will learn

  • Bound source work and preserve privacy across runtime transitions.
  • Tie migration and hosting claims to actual artifacts and honest tests.

  1. SSR, hydration and prerender contracts

    Choose page rendering options from data authority and initial-output requirements rather than treating browser-only rendering as a universal fix.

    Start learning

  2. HTTP caching, freshness and bounded source work

    Coordinate response audience, load invalidation and source deadlines without inventing a universal framework cache.

    Start learning

  3. Untrusted markup, uploads and security boundaries

    Review each input sink and public output with its own trust and resource contract.

    Start learning

  4. Testing components, loads, actions and safe evidence

    Match test claims to compiler, DOM, server and source boundaries while keeping fixtures deterministic and private data out of diagnostics.

    Start learning

  5. Adapters, environment and deployment ownership

    Match Kit 3 build artifacts to runtime capabilities and keep public/private configuration and shared state explicitly owned.

    Start learning

  6. Svelte 5, Kit 3 migration and release evidence

    Review runes, component APIs and current Kit conventions as one versioned contract with reproducible artifacts.
