useSchemaByContext

useSchemaByContext

This plugin is the simplest plugin for specifying your GraphQL schema. You can specify a schema created from any tool that emits GraphQLSchema object, and you can choose to load the schema based on the initial context (or the incoming request).

import { execute, parse, specifiedRules, subscribe, validate } from 'graphql'
import { envelop, useEngine, useSchemaByContext } from '@envelop/core'

async function getSchema({ req }): GraphQLSchema {
  if (req.isAdmin) {
    return adminSchema
  }

  return userSchema
}

const getEnveloped = envelop({
  plugins: [
    useEngine({ parse, validate, specifiedRules, execute, subscribe }),
    useSchemaByContext(getSchema)
    // ... other plugins ...
  ]
})
