## What it does

This skill guides agents through building GraphQL APIs using Apollo Server 5.x patterns rather than older v4 approaches. It covers schema definitions with scalar types, input types, interfaces, and resolvers matching the `(parent, args, contextValue, info)` signature. It also structures request context for authentication and external data integration.

The skill covers both `startStandaloneServer` and web framework integrations like Express 5 via `@as-integrations/express5`. It explicitly notes that standalone mode suits prototyping, while production setups require a full framework such as Express or Fastify. Error handling enforces `GraphQLError` from `graphql` without exposing stack traces in production.

The setup requires Node.js v20+ and TypeScript 4.7+. Projects bound to legacy Node.js runtimes or Apollo Server v4 will break on these patterns because middleware signatures and context handling changed significantly.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add apollographql/skills --skill apollo-server -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/apollo-server/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/apollo-server/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add apollographql/skills --skill apollo-server -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/apollo-server/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add apollographql/skills --skill apollo-server -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/apollo-server/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install apollographql/skills apollo-server
```

2. **Manually: put the files in place**
- File: `.github/skills/apollo-server/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add apollographql/skills --skill apollo-server -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/apollographql/skills --path skills/apollo-server
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/apollo-server/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add apollographql/skills --skill apollo-server -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/apollographql/skills/tree/HEAD/skills/apollo-server/SKILL.md

## When to use it
- scaffold an Apollo Server 5.x project with TypeScript
- define GraphQL schemas with types, inputs, and interfaces
- configure per-request context for authentication in Express or standalone mode
- prevent N+1 query bottlenecks using DataLoader

## Example prompts
- Create an Apollo Server 5 setup with Express and bearer token auth
- Write GraphQL schema typeDefs and resolvers for a blog API
- Implement DataLoader in Apollo Server context to batch user queries

# Apollo Server 5.x Guide

Apollo Server is an open-source GraphQL server that works with any GraphQL schema. Apollo Server 5 is framework-agnostic and runs standalone or integrates with Express, Fastify, and serverless environments.

## Quick Start

### Step 1: Install

```bash
npm install @apollo/server graphql
```

For Express integration:

```bash
npm install @apollo/server @as-integrations/express5 express graphql cors
```

### Step 2: Define Schema

```typescript
const typeDefs = `#graphql
  type Book {
    title: String
    author: String
  }

  type Query {
    books: [Book]
  }
`;
```

### Step 3: Write Resolvers

```typescript
const resolvers = {
  Query: {
    books: () => [
      { title: "The Great Gatsby", author: "F. Scott Fitzgerald" },
      { title: "1984", author: "George Orwell" },
    ],
  },
};
```

### Step 4: Start Server

**Standalone (Recommended for prototyping):**

The standalone server is great for prototyping, but for production services, we recommend integrating Apollo Server with a more fully-featured web framework such as Express, Koa, or Fastify. Swapping from the standalone server to a web framework later is straightforward.

```typescript
import { ApolloServer } from "@apollo/server";
import { startStandaloneServer } from "@apollo/server/standalone";

const server = new ApolloServer({ typeDefs, resolvers });

const { url } = await startStandaloneServer(server, {
  listen: { port: 4000 },
});

console.log(`Server ready at ${url}`);
```

**Express:**

```typescript
import { ApolloServer } from "@apollo/server";
import { expressMiddleware } from "@as-integrations/express5";
import { ApolloServerPluginDrainHttpServer } from "@apollo/server/plugin/drainHttpServer";
import express from "express";
import http from "http";
import cors from "cors";

const app = express();
const httpServer = http.createServer(app);

const server = new ApolloServer({
  typeDefs,
  resolvers,
  plugins: [ApolloServerPluginDrainHttpServer({ httpServer })],
});

await server.start();

app.use(
  "/graphql",
  cors(),
  express.json(),
  expressMiddleware(server, {
    context: async ({ req }) => ({ token: req.headers.authorization }),
  }),
);
````
