{"library":"dataloader","type":"library","category":null,"description":"DataLoader is a JavaScript utility designed to optimize data fetching from various backend sources like databases or web services. It achieves this by intelligently batching multiple individual data requests into a single operation and caching results, significantly reducing the number of round-trips to the backend. The current stable version is 2.2.3, with minor patch releases occurring regularly to address fixes and small improvements. Major versions, like v2.0.0, introduce breaking changes and significant architectural updates, such as becoming part of the GraphQL Foundation. A key differentiator is its core focus on solving the N+1 problem by providing a simple, consistent API that coalesces requests within a single event loop tick, making it particularly valuable in GraphQL server implementations where diverse data requirements are common. It ships with TypeScript types, ensuring robust development in typed environments and is generally released on an as-needed basis rather than a fixed cadence.","language":"javascript","status":"active","version":"2.2.3","tags":["javascript","typescript"],"last_verified":"Wed May 27","install":[{"cmd":"npm install dataloader","imports":["import { DataLoader } from 'dataloader';","import type { BatchLoadFn } from 'dataloader';","const DataLoader = require('dataloader');"]},{"cmd":"yarn add dataloader","imports":[]},{"cmd":"pnpm add dataloader","imports":[]}],"homepage":"https://graphql.org/graphql-js/dataloader/","github":"https://github.com/graphql/dataloader","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/dataloader","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/dataloader/compatibility"}}
