SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Blueprinter provides a declarative approach to serializing Ruby objects into JSON, ensuring consistent structure across apps by centralizing rules for identifiers, fields, views, and associations.

Core Features & Use Cases

  • Identifiers and fields manage stable keys and attributes across views.
  • Views and nested associations tailor serialization depth and payload for different contexts.
  • Transformers and extractors allow post-processing and customized value retrieval.

Quick Start

Define a blueprint for your model and render it to JSON with Blueprinter to see the structured output.

FAQPage Schema
How do I serialize Ruby objects to JSON using blueprints?

Serialize Ruby objects to JSON by defining a Blueprinter blueprint with declared fields, identifiers, and views. This centralizes serialization rules to produce predictable, context-specific JSON payloads across Rails or pure Ruby apps.

What is the best way to manage nested JSON associations in Ruby?

Managing nested JSON associations in Ruby is handled by declaring nested associations within Blueprinter blueprints. You can tailor serialization depth and control the generated payload for different contexts using distinct views.

Can I conditionally include fields when serializing JSON in a Rails app?

You can conditionally include fields and manage attributes across views when serializing JSON in Rails. Blueprinter supports defaults and conditional inclusion, allowing you to tailor the output payload for specific contexts.

How do I customize value extraction during Ruby JSON serialization?

Customize value extraction during Ruby JSON serialization by utilizing extractors for customized value retrieval. You can also apply transformers to post-process the generated JSON structure before returning the final output.

Does Blueprinter work with pure Ruby apps or does it require Rails?

Blueprinter works with both pure Ruby apps and Rails applications. It serializes Ruby objects into stable JSON without strict framework dependencies, applying predictable structures using identifiers, fields, views, and associations.

Why does my JSON output structure change across different API endpoints?

JSON output structures change across endpoints because Blueprinter supports multiple views for the same object. Defining distinct views tailors serialization depth and payload fields to match the specific context of each API request.
