Santhosh Janardhanan de2d83092e feat: Reinitialize frontend with SvelteKit and TypeScript
- Delete old Vite+Svelte frontend
- Initialize new SvelteKit project with TypeScript
- Configure Tailwind CSS v4 + DaisyUI
- Implement JWT authentication with auto-refresh
- Create login page with form validation (Zod)
- Add protected route guards
- Update Docker configuration for single-stage build
- Add E2E tests with Playwright (6/11 passing)
- Fix Svelte 5 reactivity with $state() runes

Known issues:
- 5 E2E tests failing (timing/async issues)
- Token refresh implementation needs debugging
- Validation error display timing

@ark/schema

Underlying schema language parsed from arktype syntax.

The parts of ArkType's type system that exist in TS (i.e. not runtime-only constraints like bounds, divisors, custom predicates, morphs etc.) are structured like this:

  • Union: a set of intersections
  • Intersection: a set of a basis and constraints
  • Basis: this is the base type to which refinements like props are applied. It is one of three things, getting narrower as you move down the list:
    • Domain: "string" | "number" | "bigint" | "object" | "symbol" parallels built-in TS keywords for non-enumerable value sets
    • Proto: Must be an instanceof some class (implies domain "object")
    • Unit: Must === some value (can be intersected with any other constraint and reduced to itself or a disjoint)
  • Constraint: an individual condition that must be satisfied:
    • Required: must have a specified literal string or symbol key and a value that conforms to a specified union or intersection
    • Optional: Required conditions met or the specified key is not present
    • Index: all keys that satisfy an index type must have values satisfying the corresponding value type

In this system, L extends/subtypes/is assignable to R if and only if the intersection L & R is equal to L.
