Typed output

justjson types writes types.ts and a zero-dependency content.ts loader — no glue code to read files:

import { loadPosts, loadSettings } from './content'

const posts = await loadPosts()       // typed, slug merged in
const settings = await loadSettings()  // Settings | null

Each entry comes back with its slug (the filename), ready for routing. It reads straight from disk, so it works in any Node-based build — including Astro and Next.js server code.
