How to use schema.gql instead of string

You can use @graphql-tools file loader to load the schema file and pass that to the server. See https://www.graphql-tools.com/docs/schema-loading#graphql-file-loader

@saihaj,

in earlier versions, it is possible to read schema.graphql file directly as below

const server = new GraphQLServer({
  typeDefs: `${__dirname}/src/schema.graphql`,
  resolvers
})

isn't it possible in versions >2.0.0? if not, how GraphQL Yoga is a batteries-included cross-platform where as we need to install two more packages jsut for loading schema?

Hey @Salmandabbakuti!

In Yoga v2 we removed a lot of dependencies in order to make it more feasible for runtimes that do not have a file system.
Actually, you don't need to install any additional packages on Node.js. 😉

You can simply use the fs module (that is shipped with Node.js by default) for reading the type definitions from the file system.

cjs example

const fs = require('fs');
const path = require('path');
const { createServer } = require('@graphql-yoga/node');

const server = createServer({
  schema: {
    typeDefs: fs.readFileSync(path.join(__dirname, 'schema.graphql'), 'utf-8'),
    resolvers: { Query: { hi: () => 'Hi Salmandabbakuti' } },
  },
});

server.start();

esm example

import { createServer } from '@graphql-yoga/node';
import * as fs from 'fs';
import * as path from 'path';
import { fileURLToPath } from 'url';


const server = createServer({
  schema: {
    typeDefs: fs.readFileSync(
      path.join(path.dirname(fileURLToPath(import.meta.url)), 'schema.graphql'),
      'utf-8'
    ),
    resolvers: { Query: { hi: () => 'Hi Salmandabbakuti' } },
  },
});

server.start();

Thank you so much for bringing this up, it should definitely be within our Migration from Yoga V1 guide. I created #1169 for tracking the progress of this.
