A Svelte permit interface crosses four ownership boundaries: source data must produce consistent views, row commands must reach the owner, form writes need server authorization and replay rules, and server page data must remain private to each request. These lessons trace failure through each boundary with one case queue so the contracts can be tested together.
Topics in this track
- Svelte Runes: Source State, Derived Views, and Effect Cleanup — Keep editable state distinct from derived queue views and reserve effects for external work.
- Svelte Props, Callbacks, and Keyed Editor Ownership — Declare component commands as callbacks and keep private drafts attached to stable records.
- SvelteKit Form Actions, Validation, and Mutation Replay — Keep a normal POST form usable without script and bind approval to server-side identity and operation rules.
- SvelteKit Request-Scoped Load and Hydration State — Pass authorized server data through a request-owned load result and preserve a stable first browser view.
