Apollo 3, Meteor and “Cannot await without a Fiber”

Help
6

Meteor skeleton has been updated for Apollo 3 in the upcoming Meteor 2.4 release. If you want to try it out give the beta a try. Prior to Meteor 2.4 the skeleton uses Apollo 2, so if you want to use the latest Apollo you need to make the necessary upgrades.

These should be:
All resolvers and queries should be async functions.

const resolvers = {
  Query: {
    getLink: async (obj, { id }) => LinksCollection.findOne(id),
    getLinks: async () => LinksCollection.find().fetch()
  }
};

Add express as a dependency to your app.

Change your server Apollo start to:

// apollo.js
import { ApolloServer } from 'apollo-server-express';
import { WebApp } from 'meteor/webapp';
import { getUser } from 'meteor/apollo';
import { makeExecutableSchema } from '@graphql-tools/schema';

const server = new ApolloServer({
  schema: makeExecutableSchema({
    typeDefs,
    resolvers,
  }),
  context: async ({ req }) => ({
    user: await getUser(req.headers.authorization)
  })
})

export async function startApolloServer() {
  await server.start();
  const app = WebApp.connectHandlers;

  server.applyMiddleware({
    app,
    cors: true
  });
}

// main.js
import { startApolloServer } from './apollo';

function insertLink({ title, url }) {
  LinksCollection.insert({title, url, createdAt: new Date()});
}

try {
  startApolloServer().then();
} catch (e) {
  console.error(e.reason);
}
