load public/private schema by authentication

[ethdev279]

Hello Guys, Congrats on v3. I really liked it. it's nice and clean🎉

earlier I used useLazyLoadedSchema for conditionally loading schema by user auth. Is that the same in v3 or any better approach to do that? I saw some plugins like useSchema and useSchemaByContext and some issues as well. I suspect there should be a better performant approach. can u please help me to find out how to do conditional schema in yoga v3

Hey @ethdev279!

Loading conditional schemas based on the request is documented here: https://the-guild.dev/graphql/yoga-server/docs/features/schema#conditional-schema

import { createServer } from 'node:http'
import { createYoga } from 'graphql-yoga'
import { getSchemaForViewer } from './schema.js'

const yoga = createYoga({
 schema: async (request) =>
 getSchemaForViewer(request.headers.get('x-schema') ?? 'default')
})
const server = createServer(yoga)

// Start the server and you're done!
server.listen(4000, () => {
 console.info('Server is running on http://localhost:4000/graphql')
})
