This plugins replaces the original `execute` of GraphQL with [`graphql-jit`](https://github.com/zalando-incubator/graphql-jit).
npm install @envelop/graphql-jit@envelop/graphql-jitThis plugins replaces the original execute of GraphQL withgraphql-jit.
```
yarn add @envelop/graphql-jit
`ts
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
}
)
]
})
`
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:
`ts
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:
`ts
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``
}
)
]
})
