Schema

Document

Document represents a single Markdown file in the file system.

type Document {
	# Title extracted from frontmatter's `title`
	title: String!
	# Title converted to a slug
	slug: String!
	# Category extracted from frontmatter's `category`
	category: String
	# All frontmatter fields
	frontmatter: JSON!
	# Document body without frontmatter
	body: String!
	# Date when a document was created
	createdAt: Date!
	# Date when a document was last updated
	updatedAt: Date!
}

documents(skip: Int, limit: Int)

Query documents with optional pagination parameters skip and limit.

Example:

{
	query {
		documents {
			title
			slug
			category
			frontmatter
			body
			createdAt
			updatedAt
		}
	}
}

document(slug: String!)

Query a single document by its slug.

Example:

{
	query {
		document(slug: "hello-world") {
			title
