GiraphQL is library for creating GraphQL schemas in typescript using a strongly typed code first approach

GiraphQL - A plugin based GraphQL schema builder for typescript

GiraphQL makes writing graphql schemas in typescript easy, fast and enjoyable. The core of GiraphQL adds 0 overhead at runtime, and has graphql as its only dependency.

By leaning heavily on typescripts ability to infer types, GiraphQL is the most type-safe way of writing GraphQL schemas in typescript/node while requiring very few manual type definitions and no code generation.

GiraphQL has a unique and powerful plugin system that makes every plugin feel like its features are built into the core library. Plugins can extend almost any part of the API by adding new options or methods that can take full advantage of GiraphQLs type system.

Hello, World

import { ApolloServer } from 'apollo-server';
import SchemaBuilder from '@giraphql/core';

const builder = new SchemaBuilder({});

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

new ApolloServer({
  schema: builder.toSchema({}),
}).listen(3000);
