Why Dataloader ?

Dataloader is used to solve the popular N+1 problem, by batching requests and making one rquest to the database to fetch multiple objects, instead of N queries, this will optimize the graphql queries significantly, more about the problem can be found here

Graphql Upload

graphql file upload was done by graphql-upload node package

Graphql Schema

full graphql schema can be found at schema.gql

Graphql Subscription

subscription is done using graphql-subscriptions, 2 events can be subscribed:
