shiguredo/swidden

Swidden is an Erlang-based HTTP API framework built on Cowboy that routes POST requests to handler modules based on a service-version-operation pattern. It enforces input validation using JSON Schema and supports custom middleware and interceptors. The system includes a test client and comprehensive tooling for development and code quality.

The application now includes a dispatch configuration file and a set of JSON Schema definitions for the 'spam' and 'spam\_admin' API areas. These schemas define the expected input structures for various endpoints, such as user creation, updates, and metrics retrieval, using JSON Schema draft-06. This change establishes the validation rules and routing mappings for these specific API handlers.

priv · high confidence

Introduces the Swidden application (version 2026.2.1), an Erlang-based HTTP API framework built on Cowboy. It provides a dynamic dispatch mechanism that routes POST requests to handler modules based on a service-version-operation pattern defined in a dispatch configuration file. The framework includes built-in JSON schema validation using Jesse, request body size limiting (8MB), and support for custom interceptors and middleware. It also exposes a test client module for making HTTP requests to the running API.

This entry establishes the baseline for the project, introducing a header-based HTTP API framework. It requires Erlang/OTP 29.0 or later and upgrades the HTTP stack to Cowboy 2.19.0 and Gun 2.6.0, while switching the JSON library to the shiguredo\_jsone fork (2025.1.0). The build and development workflow is updated to use rebar3 with a minimum OTP version of 29.0, and replaces the previous linting/formatting tools (rebar3\_efmt, rebar3\_lint, elvis) with a new pre-commit setup using \prek\ and the \shiguredo/erlang-pre-commit\ repository for \efmt\ and \elint\. Documentation and configuration files such as AGENTS.md, CLAUDE.md, and prek.toml are added to define coding standards and repository-specific settings.

The JSON Schema validation implementation has been replaced with the \jsone\_schema\ module from the jsone library, removing the dependency on \shiguredo\_jesse\. This change updates the internal API handler to use \jsone:decode/1\ and \jsone\_schema:validate\_key/2\ directly, which corrects previous behavior where malformed JSON bodies were incorrectly reported as \InvalidJSON\ instead of \MalformedJSON\, and eliminates the leakage of server absolute paths in error responses by removing the \$id\ injection that occurred with the previous library.

issues · high confidence

Added comprehensive EUnit tests for the Swidden HTTP API, including test helpers and mock handlers (\sample\_interceptor\, \sample\_middleware\, \spam\_user\_handler\, etc.). The tests verify core API behaviors such as successful CRUD operations, error handling for invalid JSON or missing bodies, redirect logic, interceptor execution, and middleware integration. It also includes unit tests for the \pascal2snake\ utility function and verifies service dispatching across different API versions.
