Deduplicate HTTP Requests

Most of the time, your GraphQL Mesh Gateway will receive multiple requests for the same data. This can happen when multiple clients request the same data, or when a single client sends multiple requests for the same data.

To reduce the load on your downstream services, you can deduplicate the requests. This means that if multiple requests for the same data are received at the same time, only one request will be sent to the downstream service, and the responses will be shared among the clients.

You can enable request deduplication by using the useRequestDeduplication plugin.

npm i @graphql-mesh/plugin-deduplicate-request

pnpm add @graphql-mesh/plugin-deduplicate-request

yarn add @graphql-mesh/plugin-deduplicate-request

bun add @graphql-mesh/plugin-deduplicate-request

import useRequestDeduplication from '@graphql-mesh/plugin-deduplicate-request'
 
export const serveConfig = {
  plugins: pluginCtx => [
    useRequestDeduplication({
      ...pluginCtx
    })
  ]
}
