Nestlang Syntax
# Schema for a product listing page
products: all products on the page (array:object)
-name: Product name (text)
-url: Product page link (link)
-price: Product price (number)
-in_stock: Whether the product is available (boolean)
-images: Product image URLs (array:link)
-variants: Available variants (array:object)
-size: Size label (text)
-available: Whether this variant is in stock (boolean)
pagination: pagination info (object)
-current_page: Current page number (number)
-total_pages: Total number of pages (number)
-next_url: Next page URL (link)
Supported Types
Type
Description
text
Visible text content (default for a field with no type and no children)
string
Alias for text, kept for older schemas — prefer text
link
An <a> element's href, instead of its visible text — use for any URL field
number
Integer or decimal
boolean
True or false
date
Date/time value
date:Y-M-D
Date with a custom format
datetime
Alias for date, kept for older schemas — prefer date
object
Nested object with child fields
array
List of objects if it has child fields, otherwise a list of text values
array:text
List of text values
array:link
List of links
array:number
List of numbers
array:boolean
List of booleans
array:date
List of dates
array:object
List of objects with child fields
string, url, and datetime still work — every existing schema keeps validating and extracting
exactly as before — the table above just reflects the names new schemas should use.
