@envelop/dataloader/esm/index.js

This plugin helps you to create a new [DataLoader](https://github.com/graphql/dataloader) instance every time your context is being built. The created instance is injected into the `context` with the name you wish to use.

export const useDataLoader = (name, builderFn) => {
    return {
        onContextBuilding({ context, extendContext }) {
            extendContext({
                [name]: builderFn(context),
            });
        },
    };
};
