Usage Example

Context building can be costly and require calling remote services. For simple GraphQL operations that only select introspection fields building a context is not necessary.

The useImmediateIntrospection can be used to short circuit any further context building if a GraphQL operation selection set only includes introspection fields within the selection set.

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

const getEnveloped = envelop({
  plugins: [
    useEngine({ parse, validate, specifiedRules, execute, subscribe }),
    useSchema(schema),
    useImmediateIntrospection()
    // additional plugins
  ]
})

In case you want to authorize that an user is authenticated before allowing introspection the plugin must be placed in front of the useImmediateIntrospection() call.

import { execute, parse, specifiedRules, subscribe, validate } from 'graphql'
import { envelop, useEngine, useImmediateIntrospection } from '@envelop/core'
import { schema } from './schema'
import { useAuthorization } from './useAuthorization'

const getEnveloped = envelop({
  plugins: [
    useEngine({ parse, validate, specifiedRules, execute, subscribe }),
    useSchema(schema),
    useAuthorization(), // place this before
    useImmediateIntrospection()
    // additional plugins
  ]
})
