graphql-orchestrator-java

Overview

GraphQL Orchestrator is a library that exposes data from various data providers using a single unified GraphQL schema. It aggregates and combines the schemas from these data providers and orchestrates the graphql queries to the appropriate services. It uses the graphql-java library as the runtime execution engine on the unified schema.

Getting Started

Requirement:

• Java 8
• Maven 3

1. Add this library to your project

   <dependency>
     <groupId>com.intuit.graphql</groupId>
     <artifactId>graphql-orchestrator-java</artifactId>
     <version>${version}</version>
   </dependency>
   
   

2. Implement the ServiceProvider interface for the services you want to stitch.

3. Use the library in your code. Example:

   // Build the stitcher with multiple services. Service interface in progress
   final GraphQLOrchestrator orchestrator = GraphQLOrchestrator.newOrchestrator()
           .instrumentations(Collections.emptyList())
           .services(Collections.emptyList())   // Implemented in Step 2
           .executionIdProvider(ExecutionIdProvider.DEFAULT_EXECUTION_ID_PROVIDER)
           .queryExecutionStrategy(new AsyncExecutionStrategy())
           .mutationExecutionStrategy(new AsyncExecutionStrategy())
           .build();
           
   //execute the request
   orchestrator.execute(executionInput);
