Parsing and Validation Caching

Parsing and Validation Caching

By default, Yoga will maintain a parsing and validation cache. If requests contain documents that have been executed before, they will not be parsed and validated again.

Using the parser cache can improve performance up to ~60%, and using the validation cache up to ~50% (based on benchmarks).

This behavior is built-in and can be optionally disabled using the parserAndValidationCache options:

Disable validation and parser caching
import { createServer } from 'node:http'
import { createYoga } from 'graphql-yoga'
import { schema } from './my-schema'
 
const yoga = createYoga({
  schema,
  parserAndValidationCache: false // disable parse and validate caching
})
 
const server = createServer(yoga)
server.listen(4000, () => {
  console.info('Server is running on http://localhost:4000/graphql')
})

Furthermore, you can provide your own cache store to both of these plugins by implementing the following interface:

Custom cache store
import { createServer } from 'node:http'
import { DocumentNode, validate } from 'graphql'
import { createYoga } from 'graphql-yoga'
import { documentCacheStore, errorCacheStore, validationCacheStore } from './my-cache'
import { schema } from './my-schema'
 
interface CacheStore<T> {
  get(key: string): T | undefined
  set(key: string, value: T): void
}
 
const yoga = createYoga({
  schema,
  parserAndValidationCache: {
    documentCache: documentCacheStore as CacheStore<DocumentNode>,
    errorCache: errorCacheStore as CacheStore<Error>,
    validationCache: validationCacheStore as CacheStore<typeof validate>
  }
})
 
const server = createServer(yoga)
server.listen(4000, () => {
  console.info('Server is running on http://localhost:4000/graphql')
})

Yoga uses a custom parser and validation cache plugin that's built-in.
