Integration with Deno

GraphQL Yoga provides you a cross-platform GraphQL Server. So you can easily integrate it into any platform besides Node.js. Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust (opens in a new tab). We will use graphql-yoga which has an agnostic HTTP handler using Fetch API (opens in a new tab)'s Request (opens in a new tab) and Response (opens in a new tab) objects.


Create a import_map.json file. Learn more about import maps (opens in a new tab)

Create a deno-yoga.ts file:

  "imports": {
    "graphql-yoga": "npm:graphql-yoga@^3.7.3"
import { createYoga, createSchema } from 'graphql-yoga'
import { serve } from 'https://deno.land/std@0.157.0/http/server.ts'
const yoga = createYoga({
  schema: createSchema({
    typeDefs: /* GraphQL */ `
      type Query {
        hello: String!
    resolvers: {
      Query: {
        hello: () => 'Hello Deno!'
serve(yoga, {
  onListen({ hostname, port }) {
      `Listening on http://${hostname}:${port}/${yoga.graphqlEndpoint}}`

And run it:

deno run --allow-net --import-map ./import_map.json index.ts
