GraphQL API Gateway

This project is an Apollo Gateway that unifies multiple GraphQL microservices into a single federated endpoint. It acts as the central entry point for handling and routing GraphQL queries.

Features

• Federated GraphQL: Combines multiple GraphQL services into a single API.
• Efficient Query Routing: Directs queries to the appropriate subgraphs.
• Scalability: Supports modular service expansion.
• Containerized Deployment: Includes a Dockerfile for easy deployment.

Project Structure

• src/server.mjs – The main server handling GraphQL queries.
• supergraph.yml – Defines the subgraphs for federation.
• Dockerfile – Configures the containerized environment.
• entrypoint.sh – Startup script for running the service.

Running the Gateway

• Recommended to run this with other services in services repo

To start the service locally:

npm install
npm start

Or, using Docker:

docker build -t graphql-gateway .
docker run -p 4000:4000 graphql-gateway

This gateway provides a seamless way to interact with multiple GraphQL microservices under a unified schema.
