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 { createYoga } from 'graphql-yoga';
import { createServer } from 'node:http';
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 yoga = createYoga({
schema: builder.toSchema(),
});
const server = createServer(yoga);
server.listen(3000);
What sets Pothos apart
- Pothos was built from the start to leverage typescript for best-in-class type-safety.
