<h2>Overview</h2>
<p>Managing database queries efficiently is crucial for any Rails application, and the JitPreloader gem addresses a common pitfall known as N+1 queries. These extra queries can significantly impact performance, often without immediate visibility. By leveraging JitPreloader, developers can streamline their data loading processes, minimize unnecessary data fetching, and ultimately enhance application responsiveness.</p>
<p>With its focus on optimization and ease of use, this gem presents a straightforward solution for handling N+1 queries. It introduces innovative features that allow developers to track, preload, and aggregate associations dynamically, ensuring that complex data requirements are met efficiently.</p>
<h2>Features</h2>
<ul>
<li>
<p><strong>N+1 Query Tracking</strong>: Automatically detects and publishes N+1 query events through ActiveSupport::Notifications, enabling tracking and logging to measure the extent of potential performance issues.</p>
</li>
<li>
<p><strong>Development Logging</strong>: Configurable to log N+1 queries along with stack traces in the development environment, helping developers identify and address inefficiencies effectively.</p>
</li>
<li>
<p><strong>Enhanced RSpec Integration</strong>: Provides the ability to wrap RSpec tests in an around(:each) block that raises exceptions for detected N+1 queries, while allowing known problematic queries to pass with tagging.</p>
</li>
<li>
<p><strong>Jit Preloading Methods</strong>: Introduces <code>jit_preload</code> and <code>jit_preload!</code> methods on ActiveRecord::Relation objects, simplifying the preloading process compared to traditional methods like includes, preload, or eager_load.</p>
</li>
<li>
<p><strong>Dynamic Aggregate Methods</strong>: Offers a <code>has_many_aggregate</code> method for ActiveRecord::Base, allowing the creation of methods that perform aggregate queries on collections, optimizing data handling.</p>
</li>
<li>
<p><strong>Max IDs per Query Control</strong>: Introduces a configurable parameter to limit the number of ids processed in a single query, preventing inefficiencies from creating overly large queries and promoting better performance.</p>
</li>
</ul>


<h2>Overview:</h2>
<p>Clio offers utilities to assist with preparing for and completing Rails upgrades. These scripts are designed to aid in the process, though they are still in the early stages and might not be compatible with all environments. Users are advised to experiment with the scripts rather than adding them to the Gemfile long-term.</p>
<h2>Features:</h2>
<ul>
<li><strong>bundle_report</strong>: Analyze your Gemfile for updates.</li>
<li><strong>Deprecation tracking</strong>: Track deprecations in RSpec tests.</li>
<li><strong>deprecations command</strong>: Store and manage deprecation warnings.</li>
<li><strong>Dual-boot Rails next</strong>: Facilitates dual-booting applications.</li>
</ul>
