Site data

Navigation, footer and settings stored in one JSON, YAML or TOML file.

Collections with Astro’s file() loader show up as Site data. One file holds them:

• A plain array or a keyed object is a list of entries.
• Parsers like (t) => JSON.parse(t).part or (t) => ({ id: JSON.parse(t).part }) edit one part of the file. The site’s own parse calls work too (yaml.load, smol-toml parse).
• A glob() of one named file (pattern: 'settings.yaml') is one settings object, in any format, without a parser.

const settings = defineCollection({
  loader: glob({ base: "./src/data", pattern: "settings.yaml" }),
  schema: z.object({ siteName: z.string(), phone: z.string().optional() }),
});

const nav = defineCollection({
  loader: file("./src/data/nav.json"),
  schema: z.object({ label: z.string(), href: z.string() }),
});
