Hello, I have questions for the migration of graphql-yoga-v1 to graphql-yoga-v2.

Previously, I have used the middlewares of express like this:

import { GraphQLServer } from "graphql-yoga";
import helmet from "helmet";
import logger from "morgan";

const server = new GraphQLServe({ 
  schema,
  ...
});

server.express.use(cors());
server.express.use(helmet());

But I couldn't find the migration guide for the legacy middlewards on graphql-yoga-v2.
I guess, I have to implement the context instead of adding express's middlewards.

const server = createServer({
  schema,
  context: (initialContext) => {
    const req = initialContext.request;

    req.isTest1 = isTest1()
    req.isTest2 = isTest2()

    return {
      ...initialContext,
      req,
    };
  }
});

Could you please share any existing official guide?

Thanks.

You can setup an Express app with those middlewares.

const yoga = createServer({
  schema,
  context: (initialContext) => {
    const req = initialContext.request;

    req.isTest1 = isTest1()
    req.isTest2 = isTest2()

    return {
      ...initialContext,
      req,
    };
  }
});
const app = express();
app.use(cors());
app.use(helmet());
app.use('/graphql', yoga);
app.listen(4000);
