@assemora/schema

Schema primitives: field definitions, type inference, neutral JSON representation.

Implementation phase: 1 — implemented.

One declaration is at once a runtime parser, a compile-time type and a JSON Schema description, so validation, the database, Studio forms, OpenAPI, the SDK and MCP all read a single source (SPEC.md §3.4, §42).

import { enumOf, number, object, string, uuid, type Infer } from '@assemora/schema'

const Article = object({
  id: uuid(),
  title: string().min(2),
  status: enumOf('draft', 'published'),
  views: number().optional(),
})

type Article = Infer<typeof Article>
// { id: string; title: string; status: 'draft' | 'published'; views?: number }

const result = Article.parse(payload)
if (!result.ok) result.issues // [{ path: ['title'], code: 'min', message: '...' }]

Parsing never throws — the caller decides what a failure means. Keys outside the declared shape are dropped rather than passed through, which is how mass assignment is prevented (SPEC.md §85).

Workspace dependencies

none, and there never will be any. pnpm boundaries enforces it: every layer and every browser bundle reads this package.
