Hive Client

Hive Client is a set of libraries and utilities for interacting with Hive, for both Schema Registry and Usage Reporting.

Available Clients

JavaScript / NodeJS Client

@graphql-hive/client (opens in a new tab) is the official library for interacting with Hive's Schema Registry and Usage Reporting.

You can refer to the following guides for getting started within your project, then revisit this page for configuring the client to your needs.

Configuration

Refer to the HivePluginOptions interface (opens in a new tab) for complete list of options and configurations you can pass to the Hive JavaScript Client.

Client Information

You can pass a custom clientInfo callback to the HivePluginOptions to have full control on how you detect a client's information.

const config: HivePluginOptions = {
  usage: {
    clientInfo(context) {
      const name = context.headers['x-graphql-client-name']
      const version = context.headers['x-graphql-client-version']
 
      if (name && version) {
        return { name, version }
      }
 
      return null
    }
  }
}

Excluding Operations

You can pass a custom exclude array to the HivePluginOptions to ignore specific operations from being reported to Hive.

const config: HivePluginOptions = {
  usage: {
    exclude: ['unwantedOperationName', 'anotherOperationName']
  }
}

Sampling

Basic sampling

With sampleRate option, you're able to control the sampling rate of the usage reporting. Setting it to 0.5 will result in 50% of the operations being sent to Hive. There is no guarantee that every operation will be reported at least once (see atLeastOnceSampler).

Default: 1 (100%)

useHive({
  /* ... other options ... */,
  usage: {
    sampleRate: 0.6 // 60% of the operations will be sent to Hive
  }
})

Dynamic sampling

GraphQL Hive client accepts a function that returns a number between 0 and 1. This allows you to implement dynamic sampling based on the operation's context.

If sampler is defined, sampleRate is ignored.

A sample rate between 0 and 1.

• 0.0 = 0% chance of being sent
• 1.0 = 100% chance of being sent.
• true = 100%
• false = 0%

useHive({
  /* ... other options ... */,
  usage: {
  sampler(samplingContext) {
      if (samplingContext.operationName === 'GetUser') {
        return 0.5 // 50% of GetUser operations will be sent to Hive
      }
 
      return 0.7; // 70% of the other operations will be sent to Hive
    }
  }
})

At-least-once sampling

If you want to make sure that every operation is reported at least once, you can use the atLeastOnceSampler. Every operation is reported at least once, but every next occurrence is decided by the sampler.

import { useHive, atLeastOnceSampler} from '@graphql-hive/client';
 
useHive({
  /* ... other options ... */,
  usage: {
    sampler: atLeastOnceSampler({
      // Produces a unique key for a given GraphQL request.
      // This key is used to determine the uniqueness of a GraphQL operation.
      keyFn(samplingContext) {
        // Operation name is a good candidate for a key, but not perfect,
        // as not all operations have names
        // and some operations may have the same name but different body.
        return samplingContext.operationName;
      },
      sampler(_samplingContext) {
        const hour = new Date().getHours();
 
        if (hour >= 9 && hour <= 17) {
          return 0.3;
        }
 
        return 0.8;
      }
    })
  }
})

Custom Integration

If your GraphQL server is not listed above, you can implement a custom integration. Start by importing and creating a Hive instance using the createHive function.

import { createHive } from '@graphql-hive/client'
 
const hive = createHive({
  enabled: true,
  debug: true, // or, false
  token: 'YOUR-TOKEN'
})

Call collectUsage as soon as a GraphQL operation execution starts, and use the return value callback when the operation ends. You may also wrap and replace the execute function with the following:

export async function executeWithHive(args: ExecutionArgs): Promise<ExecutionResult> {
  // args is ExecutionArgs of graphql-js
  const finish = hive.collectUsage(args)
  // result is ExecutionResult of graphql-js
  const result = await execute(args)
  // Use this callback to finish measuring times, and save the operation report
  finish(result)
 
  return result
}

Ruby Client

The graphql-hive gem (opens in a new tab) allows GraphQL-Ruby (opens in a new tab) users to use Hive for usage reporting.

Refer to the following guides for integration with your project:

PHP Client

The Lighthouse Hive (opens in a new tab) is third-party integration can be used to measure and collect data against all your GraphQL operations.

Rust Client

Refer to the following guides for integration with your Rust project:
