How do I integrate Seahorse with a Sinatra application?

Seahorse can be integrated with Sinatra with additional configuration, as mentioned in the README. You'll need to manually handle routing and parameter binding, unlike the automatic Rails setup. Check the source code or documentation for specific integration examples.

Seahorse vs Rails strong parameters: which is better for API validation?

Seahorse automates validation and typecasting declaratively through a DSL, while strong parameters require manual whitelisting. Seahorse reduces boilerplate but adds framework dependency; strong parameters offer more flexibility for custom logic. Choose based on your need for automation versus control.

Can Seahorse handle nested or complex data structures in APIs?

Yes, Seahorse supports nested parameters through its DSL, as seen in the example with list(:posts) { post } for outputs. You can define custom types and reuse them across inputs and outputs for consistent modeling.

Does Seahorse support XML serialization or only JSON?

Seahorse supports both JSON and XML serialization automatically, as stated in the README. The output is serialized based on the API model definition, but configuration options for custom formats may be limited.

Is Seahorse actively maintained or is it abandoned?

The project was created as a tech demo for RailsConf 2013 and the README invites contributions, but there's no indication of regular updates. Check the GitHub repository for recent activity or forks to gauge community involvement.

How to customize error messages for validation failures in Seahorse?

The README doesn't detail customization of error messages, so you may need to rely on default validations or extend the model. This limitation could be a drawback for applications requiring user-friendly error responses.

railsconf2013-tech-demo — Ruby DSL for Service APIs

What is railsconf2013-tech-demo?

Seahorse is a Ruby library that provides a declarative DSL for describing service APIs as first-class models. It solves the problem of manual parameter validation, type conversion, and serialization in web applications by automating these processes based on the API definition. With Rails integration, it seamlessly hooks into controllers and routing, reducing boilerplate code.

Target Audience

Ruby on Rails developers building RESTful APIs who want to automate validation and serialization, and teams seeking consistent API modeling across services.

Value Proposition

Developers choose Seahorse for its declarative approach that eliminates repetitive validation logic, ensures type safety, and provides automatic serialization, all while integrating smoothly with Rails conventions without requiring strong parameters.

Overview

Seahorse is a way to describe your API

Use Cases

Best For

Automating parameter validation and type conversion in Rails APIs
Reducing boilerplate code in Rails controller actions
Ensuring consistent API modeling across a Ruby application
Integrating declarative API definitions with Rails routing
Building RESTful APIs with automatic JSON/XML serialization
Simplifying API development by removing manual strong parameters

Not Ideal For

Projects not using Ruby on Rails or requiring minimal framework dependency
APIs needing dynamic, runtime validation beyond static declarative rules
Teams preferring imperative code with full control over validation logic
Applications requiring GraphQL or real-time APIs over RESTful endpoints

Pros & Cons

Pros

Declarative API Modeling

Uses a clean Ruby DSL to define operations, inputs, and outputs in a single model, reducing boilerplate and ensuring consistency, as shown with Api::Post examples in the README.

Automatic Validation & Typecasting

Validates and converts parameters automatically based on the model, eliminating manual checks and conversions, such as params[:page] being an integer without .to_i.

Seamless Rails Integration

Hooks into Rails routing and controllers with minimal setup, removing the need for strong parameters and simplifying controller actions, as demonstrated with Seahorse::Model.add_all_routes.

Consistent Serialization

Automatically serializes outputs to JSON or XML from the API model, ensuring uniform response formats without additional serialization code.

Cons

Limited Feature Breadth

Admitted in the README as a 2013 tech demo with minimal features, it may lack support for advanced API scenarios like pagination helpers or authentication hooks.

Sinatra Integration Overhead

Requires additional configuration for Sinatra apps compared to Rails, making it less seamless for non-Rails frameworks, as noted in the features section.

Potential Maintenance Risks

Being a dated tech demo, it might not be actively updated, risking compatibility issues with newer Ruby or Rails versions and limited community support.
