Overview

The GraphQL::QueryResolver is an innovative add-on for graphql-ruby that aims to optimize database queries by minimizing the notorious N+1 SELECT problem prevalent with ActiveRecord. By analyzing the Abstract Syntax Tree (AST) of incoming GraphQL queries, it intelligently matches query selections to the ActiveRecord reflections in your models. This efficiency not only streamlines data retrieval but also significantly enhances performance with a single SELECT statement for each level of the GraphQL tree.

With installation and usage made simple, this gem provides a robust solution for developers looking to improve their application's data handling capabilities. It’s an exciting tool for anyone invested in Ruby on Rails and looking to leverage GraphQL for efficient data management.

Features

  • N+1 SELECT Minimization: Effectively reduces the number of SELECT queries, enhancing performance by optimizing data fetching.

  • AST Analysis: Analyzes the incoming GraphQL queries’ AST to match selections with ActiveRecord reflections, ensuring accurate data retrieval.

  • ActiveRecord Integration: Seamlessly works with ActiveRecord models, providing a familiar environment for Ruby on Rails developers.

  • Preloading Support: Utilizes ActiveRecord's preloading mechanism to execute efficient queries, allowing for deeper relationships to be handled with ease.

  • Simple Installation: Easy to integrate into your existing Ruby on Rails application with just a simple line added to your Gemfile.

  • Open Source Collaboration: Available under the MIT License, encouraging community contributions and collaboration to enhance the tool further.

  • Development Ready: The setup process enables developers to quickly get started with testing and experimentation, promoting an efficient workflow.
