Send consistent documents + refactors

Rounds up several overdue refactors on library internals, including #134, #136, and #137.

⚠️ Minor breaking changes:

• Regenerate supergraph SDL dumps and increment query plan caching keys while upgrading (#134).
• Rename Supergraph.boundaries calls to Supergraph.resolvers (#136).

Better support for merged types without resolvers

See #135, thanks to @thomasmarshall for the suggestion.

Improved handling of resolver types

• #130: Fixes abstract resolver definitions passing through Supergraph import/export. Thanks @thomasmarshall.
• #131: Improvements to @stitch directive resolver mappings:
  • Multiple arguments attempt to match by name to the key used.
  • Abstract resolvers may specify a typeName to target specific types with specific keys.

GraphQL v2.3.0 compatibility

v1.2.3

v1.2.3

Fix lower-level root queries

Fixes a bug with collecting merged root query fields from lower-level tree positions.

Fix repathing of non-list errors

Fixes a bug with repathing non-list errors, per #117. Thanks to @shyouhei for the report.

Request overhaul + GraphQL multipart form uploads

Large refactor to center operations around the stitching Request object. This enabled support for GraphQL multipart form uploads (thanks @mikeharty), and prepares for other contextual schema possibilities. Review #108 for a complete list of changes.

⚠️ Minor breaking change

Arguments for Executable.call have changed. The method signature is now:

Executable.call(request, document, variables)

• request is now the first argument.
• former context argument has been removed in favor of request.context.
• former location argument has been removed without replacement, as executables should have implicit awareness of their assigned target.

GraphQL 2.2 compatibility

Updates the definition of Field nodes to match GraphQL v2.2.

Supergraph SDL

⚠️ Minor breaking changes

New SDL export format for Supergraph, and change in client caching hook arguments. See release notes for migration steps:

• #96
• #97

Fix error propagation

• Fixes propagation of single errors, per #93. Thanks @shyouhei for the report.
• Simplifies request string handling, and adds normalized_string and normalized_digest options.
