Getting Started

This guide walks you through setting up Hive Router from scratch. We’ll go from zero to a working GraphQL API that you can query locally. By the end, you’ll have a router serving a federated supergraph with real data.

Installation

Hive Router comes as a standalone binary or Docker image. For trying things out locally, the binary is usually the quickest option. For production deployments, you’ll probably want the Docker image.

curl -o- https://raw.githubusercontent.com/graphql-hive/router/main/install.sh | sh

docker pull ghcr.io/graphql-hive/router

Check out the GitHub Releases page for all available versions.

Get a Sample Schema

For this guide, we’ll use a demo supergraph schema. It’s the same one from our “Get Started with GraphQL Federation” guide.

This schema combines three demo subgraphs: users, products, and reviews.

Download the schema file:

curl -sSL https://federation-demo.theguild.workers.dev/supergraph.graphql > supergraph.graphql

What’s a supergraph? Think of it as a combined schema that merges all your individual subgraph schemas into one unified graph. The router uses this to figure out which subgraphs to talk to for each query.

Configure the Router

Create a config file called router.config.yaml that tells the router where to find your schema:

supergraph:
  source: file
  path: ./supergraph.graphql

That’s it for basic setup. The router will load your supergraph schema from that file.

Start the Router

Now let’s fire it up:

./hive_router

docker run \
  -p 4000:4000 \
  -v ./supergraph.graphql:/app/supergraph.graphql \
  -v ./router.config.yaml:/app/router.config.yaml \
  ghcr.io/graphql-hive/router:latest

If everything works, you’ll see logs showing the server starting up on port 4000.

Try It Out

Open http://localhost:4000 in your browser to access the GraphQL IDE. Try running this query to see federation in action:

query TopProducts {
  topProducts {
    name
    reviews {
      body
      author {
        name
      }
    }
  }
}

This query spans multiple subgraphs - it gets product data from the products service, review data from the reviews service, and user data from the users service. The router handles all the coordination behind the scenes.

What’s Next?

Now that you have the router running, dive into the Configuration Reference to see all the ways you can customize it for your specific needs.
