@nestjs-yalc/data-loader

NestJS DataLoader helpers for batching entity lookups and exposing injectable loader providers.

Use this package directly when you need the YALC dataloader primitive without the higher-level CrudGen resource factory.

Installation

npm install @nestjs-yalc/data-loader

Main Exports

• GQLDataLoader for request-scoped entity batching.
• DataLoaderFactory for creating Nest providers around a repository-backed loader.
• getDataloaderToken for deriving the provider token used by generated modules.
• SearchKeyType and helper functions for selecting lookup keys.

Example

import { DataLoaderFactory } from '@nestjs-yalc/data-loader';

export const userDataloaderProvider = DataLoaderFactory('id', UserEntity);

Documentation

CrudGen uses this package internally for generated GraphQL dataloaders: https://github.com/NestDevLab/nestjs-yalc/blob/dev/docs/crud-gen-factory.md
