graphql-request

Minimal GraphQL client supporting Node and browsers for scripts or simple apps

Features

• Most simple & lightweight GraphQL client
• Promise-based API (works with async / await)
• Typescript support
• Isomorphic (works with Node / browsers)

Install

npm add graphql-request

Quickstart

Send a GraphQL query with a single line of code. ▶️ Try it out.

import { request } from 'graphql-request'

const query = `{
  Movie(title: "Inception") {
    releaseDate
    actors {
      name
    }
  }
}`

request('https://api.graph.cool/simple/v1/movies', query).then((data) => console.log(data))

Usage

import { request, GraphQLClient } from 'graphql-request'

// Run GraphQL queries/mutations using a static function
request(endpoint, query, variables).then((data) => console.log(data))

// ... or create a GraphQL client instance to send requests
const client = new GraphQLClient(endpoint, { headers: {} })
client.request(query, variables).then((data) => console.log(data))

Examples

Authentication via HTTP header

import { GraphQLClient } from 'graphql-request'

async function main() {
  const endpoint = 'https://api.graph.cool/simple/v1/cixos23120m0n0173veiiwrjr'

  const graphQLClient = new GraphQLClient(endpoint, {
    headers: {
      authorization: 'Bearer MY_TOKEN',
    },
  })

  const query = /* GraphQL */ `
    {
      Movie(title: "Inception") {
        releaseDate
        actors {
          name
        }
      }
    }
  `

  const data = await graphQLClient.request(query)
  console.log(JSON.stringify(data, undefined, 2))
}

main().catch((error) => console.error(error))

Passing more options to fetch

import { GraphQLClient } from 'graphql-request'

async function main() {
  const endpoint = 'https://api.graph.cool/simple/v1/cixos23120m0n0173veiiwrjr'

  const graphQLClient = new GraphQLClient(endpoint, {
    credentials: 'include',
    mode: 'cors',
  })

  const query = /* GraphQL */ `
    {
      Movie(title: "Inception") {
        releaseDate
        actors {
          name
        }
      }
    }
  `

  const data = await graphQLClient.request(query)
  console.log(JSON.stringify(data, undefined, 2))
}

main().catch((error) => console.error(error))

Using variables

import { request } from 'graphql-request'

async function main() {
  const endpoint = 'https://api.graph.cool/simple/v1/cixos23120m0n0173veiiwrjr'

  const query = /* GraphQL */ `
    query getMovie($title: String!) {
      Movie(title: $title) {
        releaseDate
        actors {
          name
        }
      }
    }
  `

  const variables = {
    title: 'Inception',
  }

  const data = await request(endpoint, query, variables)
  console.log(JSON.stringify(data, undefined, 2))
}

main().catch((error) => console.error(error))

Error handling

import { request } from 'graphql-request'

async function main() {
  const endpoint = 'https://api.graph.cool/simple/v1/cixos23120m0n0173veiiwrjr'

  const query = /* GraphQL */ `
    {
      Movie(title: "Inception") {
        releaseDate
        actors {
          fullname # "Cannot query field 'fullname' on type 'Actor'. Did you mean 'name'?"
        }
      }
    }
  `

  try {
    const data = await request(endpoint, query)
    console.log(JSON.stringify(data, undefined, 2))
  } catch (error) {
    console.error(JSON.stringify(error, undefined, 2))
    process.exit(1)
  }
}

main().catch((error) => console.error(error))

Using require instead of import

const { request } = require('graphql-request')

async function main() {
  const endpoint = 'https://api.graph.cool/simple/v1/cixos23120m0n0173veiiwrjr'

  const query = /* GraphQL */ `
    {
      Movie(title: "Inception") {
        releaseDate
        actors {
          name
        }
      }
    }
  `

  const data = await request(endpoint, query)
  console.log(JSON.stringify(data, undefined, 2))
}

main().catch((error) => console.error(error))

Cookie support for node

npm install fetch-cookie

require('fetch-cookie/node-fetch')(require('node-fetch'))

import { GraphQLClient } from 'graphql-request'

async function main() {
  const endpoint = 'https://api.graph.cool/simple/v1/cixos23120m0n0173veiiwrjr'

  const graphQLClient = new GraphQLClient(endpoint, {
    headers: {
      authorization: 'Bearer MY_TOKEN',
    },
  })

  const query = /* GraphQL */ `
    {
      Movie(title: "Inception") {
        releaseDate
        actors {
          name
        }
      }
    }
  `

  const data = await graphQLClient.rawRequest(query)
  console.log(JSON.stringify(data, undefined, 2))
}

main().catch((error) => console.error(error))

Receiving a raw response

The request method will return the data or errors key from the response. If you need to access the extensions key you can use the rawRequest method:

import { rawRequest } from 'graphql-request'

async function main() {
  const endpoint = 'https://api.graph.cool/simple/v1/cixos23120m0n0173veiiwrjr'

  const query = /* GraphQL */ `
    {
      Movie(title: "Inception") {
        releaseDate
        actors {
          name
        }
      }
    }
  `

  const { data, errors, extensions, headers, status } = await rawRequest(endpoint, query)
  console.log(JSON.stringify({ data, errors, extensions, headers, status }, undefined, 2))
}

main().catch((error) => console.error(error))

FAQ

What's the difference between graphql-request, Apollo and Relay?

graphql-request is the most minimal and simplest to use GraphQL client. It's perfect for small scripts or simple apps.

Compared to GraphQL clients like Apollo or Relay, graphql-request doesn't have a built-in cache and has no integrations for frontend frameworks. The goal is to keep the package and API as minimal as possible.
