[yacosta738]

Context

No API technology is currently detected. GraphQL, gRPC, tRPC, and OpenAPI/Swagger are all widely used.

Technologies to Add

Technology	Detection Method	Details
GraphQL	packages	graphql, @apollo/client, @apollo/server, urql, graphql-yoga
GraphQL	config_files	.graphqlrc, .graphqlrc.{json,yaml,yml}
GraphQL	file_extensions	.graphql, .gql
gRPC	packages	@grpc/grpc-js, grpc
gRPC	file_extensions	.proto
tRPC	packages	@trpc/server, @trpc/client, @trpc/react-query
OpenAPI	config_files	openapi.yaml, openapi.json, swagger.yaml, swagger.json
OpenAPI	packages	swagger-ui-express, @nestjs/swagger

Implementation

• Catalog-only changes
• Mix of packages, config_files, and file_extensions

Acceptance Criteria

• GraphQL detected in projects with GraphQL deps or .graphql files
• tRPC detected in projects with tRPC packages
• cargo test suggest passes
