Supergraph / Proxy Source

Hive Gateway can retrieve a supergraph from a wide range of sources.

This includes:

Hive Schema Schema Registry
Apollo GraphOS / Studio
Custom Sources

In addition you can also proxy any GraphQL API, by either introspection or providing a schema file.

Supergraph

Hive Gateway has built in support for fetching supergraphs from the Hive Schema Registry. You can either choose to provide the configuration via CLI parameters, environment variables or a configuration file.

hive-gateway supergraph <endpoint> --hive-cdn-key <api_key>

Hive Gateway has built in support for fetching supergraphs from the Apollo GraphOS Registry. You can either choose to provide the configuration via CLI parameters, environment variables or a configuration file.

hive-gateway supergraph <graph_id>[@<variant>] --apollo-key <api_key>

You can provide a custom supergraph source, along with other options to customize the polling/retry behavior.

gateway.config.ts

import { defineConfig } from '@graphql-hive/gateway'
 
export const gatewayConfig = defineConfig({
  supergraph: () =>
    // Fetch the supergraph from the schema registry
    fetch('https://my-registry.com/supergraph.graphql', {
      headers: {
        Authorization: 'Bearer MY_TOKEN'
      }
    }).then(res => res.text()),
 
  plugins: ctx => [
    // You can also write your custom plugins to interact with the schema registry
    useMyCustomPlugin(ctx)
  ]
})

You can point to supergraph.graphql located in your file system.

hive-gateway supergraph ./supergraph.graphql

Polling

You can configure the polling interval for the supergraph source.

gateway.config.ts

import { defineConfig } from '@graphql-hive/gateway'
 
export const gatewayConfig = defineConfig({
  supergraph: {
    /* Supergraph Configuration */
  },
  // Poll the schema registry every 10 seconds
  pollingInterval: 10_000
})

Proxy

Instead of serving a supergraph, you can also use Hive Gateway to proxy any existing GraphQL API. This allows you to add features such as usage reporting or persisted documents without modifying your existing GraphQL API.
