Pothos GraphQL

Pothos is a plugin based GraphQL schema builder for typescript.

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

Pothos is the most type-safe way to build GraphQL schemas in typescript, and by leveraging type inference and typescript's powerful type system Pothos requires very few manual type definitions and no code generation.

Pothos 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 the Pothos type system.

Hello, World

import { createServer } from '@graphql-yoga/node';
import SchemaBuilder from '@pothos/core';

const builder = new SchemaBuilder({});

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

const server = createServer({
  schema: builder.toSchema({}),
});

server.start();

What sets Pothos apart

Pothos was built from the start to leverage typescript for best-in-class type-safety.
Pothos has a clear separation between the shape of your external GraphQL API, and the internal representation of your data.
Pothos comes with a large plugin ecosystem that provides a wide variety of features while maintaining great interoperability between plugins.
Pothos does not depend on code-generation or experimental decorators for type-safety.
Pothos has been designed to work at every scale from small prototypes to huge Enterprise applications, and is in use at some of the largest tech companies including Airbnb and Netflix.
