Graphism

Graphism is a library for creating GraphQL servers in Deno & Deno Deploy.

compatible with GraphQL.js 16.6.0
out of the box GraphiQL
support for GraphQL JIT

import { serve } from 'wren';
import { GET } from 'wren/route.ts';
import * as Response from 'wren/response.ts';
import { GraphQL } from 'graphism';
import SchemaBuilder from 'pothos';

const builder = new SchemaBuilder({});

builder.queryType({
  fields: (t) => ({
    hello: t.string({
      args: {
        name: t.arg.string(),
      },
      resolve: (_parent, { name }) => `Hello, ${name || 'World'}`,
    }),
  }),
});


const schema = builder.toSchema();

const routes = [
  GET('/', () => Response.OK('Graphism')),
  GraphQL("/graphql", schema)
];

serve(routes, { port: 3000 });

Getting Started

Generate a Wren project

deno run -A -r https://wren.deno.dev my-graphql-server

Add Graphism & (optionally) Pothos

In import_map.json add graphql, graphism and pothos as dependencies:

{
  "imports": {
    // ...
    "graphql": "https://esm.sh/graphql@16.6.0",
    "graphism": "https://deno.land/x/graphism@0.1.0/mod.ts",
    "pothos": "https://esm.sh/@pothos/core@3.21.0"
  }
}

Build the GraphQL Schema

const builder = new SchemaBuilder({});

builder.queryType({
  fields: (t) => ({
    hello: t.string({
      args: {
        name: t.arg.string(),
      },
      resolve: (_parent, { name }) => `Hello, ${name || 'World'}`,
    }),
  }),
});


const schema = builder.toSchema();

Add the GraphQL route

const routes = [
  GET('/', () => Response.OK('Graphism')),
  GraphQL("/graphql", schema)
];

serve(routes, { port: 3000 });

Start the server

deno task start
