WPGraphQL Polylang Extension

Adds language and translations fields to posts, pages, and custom post types, enabling full multilingual querying directly in GraphQL, as shown in the example query in the README.

Follows WPGraphQL's schema extension pattern for predictable, type-safe queries, respecting both Polylang's data structure and GraphQL's type system, as per the project philosophy.

Supports multilingual Advanced Custom Fields options pages with additional plugins, allowing site-wide settings per language, though it requires ACF Pro and specific setup steps detailed in the README.

Provides language filtering in queries and setting language during create and update mutations, offering complete control over content, as evidenced by the where arguments and mutation support features.
