Fastify Integration#

Install#

yarn add fastify graphql graphql-ez @graphql-ez/fastify
yarn add -D @types/node

pnpm add fastify graphql graphql-ez @graphql-ez/fastify
pnpm add -D @types/node

npm install fastify graphql graphql-ez @graphql-ez/fastify
npm install -D @types/node

Usage#

Server module

import Fastify from 'fastify';

import { ezApp } from './ez';

const app = Fastify({
  logger: true,
});

const { fastifyPlugin } = ezApp.buildApp({
  // ...
});

app.register(fastifyPlugin);

app.listen({ port: 8080 });

EZ App module

import { CreateApp, gql } from '@graphql-ez/fastify';

export const ezApp = CreateApp({
  // You can use any valid GraphQL Schema
  schema,
  ez: {
    plugins: [
      // EZ Plugins
    ],
  },
  envelop: {
    plugins: [
      // Envelop Plugins
    ],
  },
  // Other Options
});

Build Custom Context#

The Fastify specific arguments are optional since, in some specific contexts, those might not available, but you can always use the HTTP's IncomingMessage req

import { CreateApp, BuildContextArgs, InferContext } from '@graphql-ez/fastify';

function buildContext({ req, fastify }: BuildContextArgs) {
  // IncomingMessage
  req;

  // FastifyRequest | undefined
  fastify?.request;

  return {
    foo: 'bar',
  };
}

// This snippet allows you to infer the context returned by your 'buildContext' and add it to the EZContext interface
declare module 'graphql-ez' {
  interface EZContext extends InferContext<typeof buildContext> {}
}

export const ezApp = CreateApp({
  // ...
  buildContext,
});

To enable CORS, specify the cors property in your configuration

CreateApp({
  cors: true,
});

Check fastify-cors for all the available options.

CreateApp({
  // Check https://github.com/fastify/fastify-cors#options
  cors: {
    // ...
  },
});
