import compression from "compression";
import cors from "cors";
import schema from "./graphql/schema";

const PORT = process.env["PORT"] || 3000;
const app = express();

const server = new ApolloServer({
  ...schema,
  validationRules: [depthLimit(7)],
});

app.use("*", cors());
app.use(compression());
server.applyMiddleware({ app, path: "/graphql" });

const httpServer = createServer(app);
httpServer.listen({ port: PORT }, (): void => {
  console.log(`GraphQL server ready http://localhost:${PORT}/graphql`);
