# Apollo Server Fastify

## Introduction

**A community-maintained package for connecting Fastify to Apollo GraphQL server.**

This is a simple package that easily allows you to connect your own Fastify server implementation to an Apollo Server instance.

## **Requirements**

- **[Node.js v14](https://nodejs.org/)** or later 
- **[Fastify v4](https://www.fastify.io/)** or later
- **[GraphQL.js v16](https://graphql.org/graphql-js/)** or later
- **[Apollo Server v4](https://www.apollographql.com/docs/apollo-server/)** or later


## **Installation**

```bash
npm install @oly_op/apollo-server-fastify @apollo/server graphql fastify
```

## **Usage**

Setup [Fastify](https://www.fastify.io/) & [Apollo Server](https://www.apollographql.com/docs/apollo-server/) like you usually would and then connect the two by using the `fastifyApollo` plugin: 

```typescript
import Fastify from "fastify"
import { ApolloServer, BaseContext } from "@apollo/server"
import fastifyApollo, { fastifyApolloDrainPlugin } from "@oly_op/apollo-server-fastify"
// ...

const fastify = Fastify()

const apollo = new ApolloServer<BaseContext>({
  typeDefs,
  resolvers,
  plugins: [
    fastifyApolloDrainPlugin(fastify),
  ],
})

await apollo.start()

// ...

await fastify.register(fastifyApollo(apollo))
```

Alternatively you can use the exported function `fastifyApolloHandler` which can be passed into any [Fastify route handler](https://www.fastify.io/docs/latest/Reference/Routes/).
This allows you to explicitly set all routing options, for example the URL path and accepted methods.

Examples shown below:

```typescript
import { fastifyApolloHandler } from "@oly_op/apollo-server-fastify"

// ... setup Fastify & Apollo

fastify.post("/graphql", fastifyApolloHandler(apollo))

fastify.get("/api", fastifyApolloHandler(apollo))

fastify.route({
  url: "/graphql",
  method: ["GET", "POST", "OPTIONS"],
  handler: fastifyApolloHandler(apollo),
})
```

Please see the [example](https://github.com/olyopop/apollo-server-fastify/tree/main/example).

## **Context**

Apollo Server 4 (AS4) has moved context setup outside of the `ApolloServer` constructor.

Define you're own context function and pass it in to the `context` option. For example:

```typescript
import { ApolloServer } from "@apollo/server"
import fastifyApollo, { fastifyApolloHandler, ApolloFastifyContextFunction } from "@oly_op/apollo-server-fastify"
// ...

interface MyContext {
  authorization: JWTPayload | false;
}

const apollo = new ApolloServer<MyContext>({ resolvers, typeDefs })

const myContextFunction: ApolloFastifyContextFunction<MyContext> = async request => ({
  authorization: await isAuthorized(request.headers.authorization),
})

await fastify.register(fastifyApollo(apollo), {
  context: myContextFunction,
})

// OR

await fastify.post("/graphql", fastifyApolloHandler(apollo, {
  context: myContextFunction,
}))
```

## **API**

All options and generics are optional other than passing in the `ApolloServer` instance.

### `fastifyApollo`

```typescript
export default function fastifyApollo<Context extends BaseContext = BaseContext>(
  apollo: ApolloServer<Context>,
): FastifyPluginAsync<ApolloFastifyPluginOptions<Context>>;
```

### `fastifyApolloHandler`

```typescript
export function fastifyApolloHandler<Context extends BaseContext = BaseContext>(
  apollo: ApolloServer<Context>,
  options?: ApolloFastifyHandlerOptions<Context>,
): RouteHandlerMethod;
```

### `ApolloFastifyContextFunction`
```typescript
export type ApolloFastifyContextFunction<Context> =
  (request: FastifyRequest, reply: FastifyReply) => Promise<Context>;
```

### `ApolloFastifyPluginOptions`:

- `path`
  - type: `string | undefined`
  - default: `"/graphql"`
- `method`
  - type: `HTTPMethod | HTTPMethod[]`
  - default: `["GET", "POST", "OPTIONS"]`
- `context`
  - type: [ApolloFastifyContextFunction](#ApolloFastifyContextFunction)
  - default: `async () => ({})`

[`HTTPMethod`](https://www.fastify.io/docs/latest/Reference/TypeScript/#fastifyhttpmethods) is exported from Fastify.

### `ApolloFastifyHandlerOptions`:

- `context`
  - type: [ApolloFastifyContextFunction](#ApolloFastifyContextFunction)
  - default: `async () => ({})`

### HTTPS/HTTP2

All functions and types optionally allow you to pass in a Server type to Fastify (the default is `http.Server`).

## **Node.JS v14**

Please pass in `forceConnections: true` to Fastify to correctly shutdown you're server on close and not hang incoming requests.
