Neon Series

1. Problem Statement

Struggling to keep complex Ruby logic readable as the number of classes and operations grows? You're not alone. When a project contains many connected entities, validations, collections, and supporting operations, even familiar structures may form a confusing system. One class may gradually receive too many responsibilities, while a change in logic may affect several program sections at once. Without a clear map, it becomes harder to follow data movement, locate the source of an error, and explain the role of each component. Neon Series helps organize broader Ruby scenarios through responsibility division, validation, and structural review.

2. Solution

This course will teach you how to examine, divide, and organize broader Ruby program logic. You will work with layered validation, objects, service classes, modules, collections, and sequences of operations. The materials show how to separate core entities from data processing and supporting logic. Practical scenarios guide you through reviewing existing code, identifying overloaded components, and revising their structure. Neon Series is suitable for learners who want to build Ruby projects with clearer relationships between data, rules, and actions.

3. What’s Inside

Module 1: Reading a Larger Codebase — how to review a broader group of files, identify key classes, and locate the main execution route.

Module 2: Responsibility Mapping — how to create a role map and determine which components handle data, validation, calculations, and output.

Module 3: Coordinating Service Classes — how to use separate classes for operations that should not belong to core entities.

Module 4: Complex Collection Processing — how to combine sorting, grouping, filtering, and data conversion in a sequential process.

Module 5: Validation Rules — how to organize several validation rules and form clear messages for different scenarios.

Module 6: Object State Changes — how to control changes in object state and avoid unexpected data updates.

Module 7: Coordinating Multiple Modules — how to divide shared behavior between modules and use it across different project sections.

Module 8: Custom Error Structure — how to create separate error types for clearer handling of problematic scenarios.

Module 9: Logging and Review Notes — how to record key execution stages and use those records to examine program logic.

Module 10: Refactoring Long Methods — how to divide overloaded methods into shorter sections with separate roles.

Module 11: Testing Logic With Examples — how to prepare sets of starting values and check expected behavior across different components.

Module 12: Neon Project Scenario — a learning project containing several entities, service classes, validation rules, collections, and error handling.

Module 13: Final Structure Review — a final review of files, dependencies, naming, and the responsibility of each component.

4. Who is this for?

✅ Suitable if you have already worked with classes, modules, multiple files, and detailed collections and want to organize broader Ruby scenarios more clearly.
❌ Not suitable if you are still learning basic syntax or have not yet worked with objects, data validation, and logic separation.
