gql

Universal GraphQL HTTP middleware for Deno.

Features

Get started

Vanilla

The simplest setup with std/http:

import { Server } from 'https://deno.land/std@0.179.0/http/server.ts'
import { GraphQLHTTP } from 'https://deno.land/x/gql/mod.ts'
import { makeExecutableSchema } from 'https://esm.sh/@graphql-tools/schema@9.0.17'
import { gql } from 'https://deno.land/x/graphql_tag@0.1.1/mod.ts'

const typeDefs = gql`
  type Query {
    hello: String
  }
`

const resolvers = { Query: { hello: () => `Hello World!` } }

const s = new Server({
  handler: async (req) => {
    const { pathname } = new URL(req.url)

    return pathname === '/graphql'
      ? await GraphQLHTTP<Request>({
          schema: makeExecutableSchema({ resolvers, typeDefs }),
          graphiql: true
        })(req)
      : new Response('Not Found', { status: 404 })
  },
  addr: ':3000'
})

s.listenAndServe()

Then run:

$ curl -X POST localhost:3000/graphql -d '{ "query": "{ hello }" }'
{
  "data": {
    "hello": "Hello World!"
  }
}
