Unreleased

Support JSON responses defined directly in Phoenix controllers, including OpenAPI schemas and TypeScript interfaces.
Infer OpenAPI types for literal response values and fields guarded by && or unless.

Generate valid YAML for nested objects, arrays, and polymorphic schemas.
Preserve flat request parameter shapes and detect qualified Ecto.Changeset.cast/3 calls.
Quote response property names that are not valid TypeScript identifiers.
Regenerate compiler output when routers, schemas, project configuration, or other source files change.
Recover from invalid compiler manifests without unsafe term decoding.

Ecto schema type inference (all types including Enum, arrays, embeds)
JSON view AST extraction (field detection, nested views, $ref generation)
Router introspection (paths, verbs, path parameters)
OpenAPI 3.1 spec generation (JSON and YAML)
TypeScript .d.ts output with correct types, optional ?, enum unions, array syntax
mix phoenix_spec.gen task
Mix compiler for auto-regeneration on file changes
Optional field detection via @optional and inline conditionals
@field_types annotation for computed fields
Embedded schemas (embeds_one → inline object, embeds_many → array)
Request body schemas from controller and schema changeset/2 cast fields
Response status code inference from controller AST
Operation summaries and unique operationIds
Error responses (404, 422) by action type
Association traversal (comment.user.name)
Schema inference from aliases when no struct pattern match
Inline map literal detection as object schemas
Fallback extraction from private functions and action inline maps
Non-controller route filtering (LiveView, OpenApiSpex, etc.)
Polymorphic oneOf schemas from multiple data/1 struct clauses
