SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill removes the guesswork and repetitive setup when building RESTful APIs in ColdBox by providing clear patterns for routing, handlers, authentication, versioning, and consistent response formatting so teams can ship stable APIs faster.

Core Features & Use Cases

  • RestHandler patterns & rendering: use RestHandler and event.renderData to produce consistent JSON responses and proper HTTP status codes.
  • Authentication & token lifecycle: implement JWT/bearer authentication, login/refresh/logout flows, and secure endpoints with cbSecurity.
  • Versioning, routing & pagination: organize APIs into modules for version isolation, define resource routes, and return paginated memento-style payloads with meta and links.
  • Use Case: implement a versioned users/posts API with JWT-secured endpoints, create/update/delete actions, validation errors as 422 responses, and paginated index endpoints.

Quick Start

Create a RestHandler users API in a module with /api/v1 routing, JWT login/refresh endpoints, and use event.renderData for all JSON success and error responses.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a REST API in ColdBox with proper JSON responses and HTTP status codes?▼

Use RestHandler and event.renderData to build ColdBox REST APIs that output consistent JSON responses with proper HTTP status codes. This approach standardizes success and error payloads across all endpoints.

How do I implement JWT authentication and token refresh flows in a ColdBox REST API?▼

Implement JWT authentication in a ColdBox REST API by securing endpoints with cbSecurity. Build login, refresh, and logout flows to manage the bearer token lifecycle for protected resources.

What is the best way to version REST API routes using ColdBox modules?▼

The best way to version REST API routes in ColdBox is organizing APIs into separate modules for version isolation. Define resource routes within these modules to maintain clean versioned endpoints.

How do I return paginated data with meta and links in a ColdBox REST API?▼

Return paginated data in a ColdBox REST API by structuring memento-style payloads that include pagination metadata and links. This provides clients with navigational context for large resource collections.

How should I handle input validation errors and return them in a ColdBox REST API?▼

Handle input validation errors in a ColdBox REST API by returning standardized 422 HTTP status code responses. Use event.renderData to format these validation errors as consistent JSON payloads.

Can I use this ColdBox RestHandler approach for CRUD routing and memento-style resource representations?▼

Yes, you can use ColdBox RestHandler for CRUD routing and memento-style resource representations. It supports create, update, and delete actions while ensuring standardized JSON formatting for production APIs.
