apollo-compiler@1.32.0

Features

• Introduce ExecutableDocumentBuilder for operations with multiple sources - trevor-scheer, pull/1017

  Adds an ExecutableDocumentBuilder that follows the same pattern as
  SchemaBuilder, letting callers assemble an ExecutableDocument from
  multiple sources before validation. API additions:

  • ExecutableDocumentBuilder with new(), add_ast_document(), parse(),
    and build() methods.
  • ExecutableDocument::builder() convenience constructor.
  • Parser::parse_into_executable_builder() for multi-file parsing.

  use apollo_compiler::{Schema, ExecutableDocument};
  use apollo_compiler::validation::DiagnosticList;
  
  let schema_src = "type Query { user: User } type User { id: ID }";
  let schema = Schema::parse_and_validate(schema_src, "schema.graphql").unwrap();
  
  let mut errors = DiagnosticList::new(Default::default());
  let doc = ExecutableDocument::builder(Some(&schema), &mut errors)
      .parse("query GetUser { user { id } }", "query1.graphql")
      .parse("query GetMore { user { id } }", "query2.graphql")
      .build();
  
  assert!(errors.is_empty());
  assert_eq!(doc.operations.named.len(), 2);

Fixes

• Validate interface field type covariance per GraphQL spec - dariuszkuc, pull/1036

  Implements the IsValidImplementationFieldType rule from the GraphQL spec.
  Previously, apollo-compiler only checked that implementing types contained
  all fields required by their interfaces but did not verify that implementing
  field types were valid subtypes. Schemas such as the following now correctly
  fail validation:

  interface Foo { x: String! }
  type Bar implements Foo { x: String }

  The new check covers non-null covariance, list item covariance, named-type
  subtyping (object/interface hierarchy), argument-name parity, argument-type
  invariance, and rejects extra non-null arguments on the implementing field.

  Note: schemas that previously passed validation but violated this rule will
  now report errors.
