graphql-pg v1.0.21

graphql-pg

Introduction

GraphQL and PostgreSQL are both fantastic technologies and are already used a lot together to build great applications. But it often take a considerable amount of developer time to bring both together in a performant manner due to the compositional nature of GraphQL.

Two problems often arise:

1) sending to many SQL queries over the network, resulting in the N+1 problem 2) more complex and handwritten SQL queries, which will eagerly (over-) fetch data, trying to mitigate the N+1 problem

GraphQL-PG circumvents those problems by pushing down the compositional nature of GraphQL right into PostgreSQL. This is done by transpiling a GraphQL query into a single optimized SQL statement.
