@envelop/graphql-jit

This plugins replaces the original execute of GraphQL with graphql-jit.

Getting Started

yarn add @envelop/graphql-jit

Usage Example

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

const getEnveloped = envelop({
  plugins: [
    useEngine({ parse, validate, specifiedRules, execute, subscribe }),
    // ... other plugins ...
    useGraphQlJit(
      {
        // your compiler options here. See https://github.com/zalando-incubator/graphql-jit#compiledquery--compilequeryschema-document-operationname-compileroptions
      },
      {
        onError: (e: Error) => {} // custom error handler
      }
    )
  ]
})

Conditional Execution

If you wish to conditionally use the JIT executor based on the incoming request, you can use enableIf config flag and return a boolean based on the ExecutionArgs:

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

const getEnveloped = envelop({
  plugins: [
    useEngine({ parse, validate, specifiedRules, execute, subscribe }),
    // ... other plugins ...
    useGraphQlJit(
      {
        // your compiler options here. See https://github.com/zalando-incubator/graphql-jit#compiledquery--compilequeryschema-document-operationname-compileroptions
      },
      {
        enableIf: executionArgs => executionArgs.contextValue.shouldUseJit
      }
    )
  ]
})

## Configuring JIT cache

You can configure the JIT cache with the following options:

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

const getEnveloped = envelop({
  plugins: [
    useEngine({ parse, validate, specifiedRules, execute, subscribe }),
    // ... other plugins ...
    useGraphQlJit(
      {
        // your compiler options here
      },
      {
        cache: lru() // Pass in a custom cache instance, by default a new LRU cache is created which uses the default `max` and `ttl` settings
      }
    )
  ]
})
