Computed fields

Computed fields become ordinary queryable metadata. Add them alongside a collection's schema:

computed: {
  upperTitle: {
    schema: z.string(),
    resolve: ({ data }) => data.title.toUpperCase(),
  },
}

When computation runs

Resolvers run during preparation and can be asynchronous. Their results are validated by the field schema and stored for runtime queries.

Resolvers receive the entry's id, validated data, and captured readBody() text when available. They work on one entry; collection-wide calculations belong in application queries.

Use field selection to request a computed field in your query results.
