N1Loader: Solving N+1 Issues for Ruby Developers
The article introduces N1Loader, a Ruby gem designed to solve N+1 issues in Ruby applications. N+1 issues occur when a database query is executed multiple times instead of being optimized to retrieve all necessary data in a single query. N1Loader provides a convenient DSL (Domain Specific Language) that allows developers to define N+1 ready loaders, which can be injected into objects to avoid N+1 problems. The gem is highly recommended for GraphQL APIs and works well with ActiveRecord versions 5, 6, and 7. It also offers a standalone mode for non-ActiveRecord projects. N1Loader can be used to resolve N+1 issues in various scenarios, such as HTTP requests, data loading, and complex calculations. The article highlights the killer feature of N1Loader in combination with ArLazyPreload, which enhances ActiveRecord and eliminates the need for defining associations. The article concludes by encouraging developers to try out N1Loader and benefit from its ability to solve N+1 issues and improve performance in Ruby applications.
