Get started

Vanilla

The simplest setup with std/http:

import { serve } from 'https://deno.land/std@0.90.0/http/server.ts'
import { GraphQLHTTP } from 'https://deno.land/x/gql/mod.ts'
import { makeExecutableSchema } from 'https://deno.land/x/graphql_tools/mod.ts'
import { gql } from 'https://deno.land/x/graphql_tag/mod.ts'

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

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

const schema = makeExecutableSchema({ resolvers, typeDefs })

const s = serve({ port: 3000 })

for await (const req of s) {
  req.url.startsWith('/graphql')
    ? await GraphQLHTTP({
        schema,
        graphiql: true
      })(req)
    : req.respond({
        status: 404
      })
}

Then run:

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