Production-ready Node.js GraphQL server for Vercel Serverless Functions.

---

Note: These docs are subject to change, as this library is under construction. Expect things to be broken!

📦 Installation

npm install --save @saeris/apollo-server-vercel graphql
# or
yarn add @saeris/apollo-server-vercel graphql

🔧 Usage

import { ApolloServer } from "@saeris/apollo-server-vercel";

// Construct a schema, using GraphQL schema language
const typeDefs = `
  type Query {
    hello: String
  }
`;

// Provide resolver functions for your schema fields
const resolvers = {
  Query: {
    hello: () => 'Hello world!',
  },
};

const server = new ApolloServer({
  typeDefs,
  resolvers,

  // By default, the GraphQL Playground interface and GraphQL introspection
  // is disabled in "production" (i.e. when `process.env.NODE_ENV` is `production`).
  //
  // If you'd like to have GraphQL Playground and introspection enabled in production,
  // the `playground` and `introspection` options must be set explicitly to `true`.
  playground: true,
  introspection: true,
});

export default server.createHandler();

Additionally, this project uses eslint, typescript, and prettier, all three of which are automatically run on each commit via husky + lint-staged. To manually lint and test, use the following commands:

Lint:

yarn lint

Typecheck:

yarn typecheck

Test and watch for changes:
