dartapi_core 0.1.0

Core utilities for building typed, structured REST APIs in Dart, including routing, validation, and middleware support.

0.1.0

Framework extraction (Milestone 1) — dartapi_core is now a standalone framework.

• Add DartAPI class — the central application class with opt-in middleware (enableCompression, enableBackgroundTasks, enableTimeout, enableRateLimit, enableMetrics, enableHealthCheck, enableDocs) and lifecycle hooks (onStartup, onShutdown). No longer requires the CLI to use.
• Add RouterManager — registers BaseController instances with a Shelf Router; collects all ApiRoutes for OpenAPI generation.
• Add InlineController — define routes inline without creating a dedicated controller class.
• Add AppConfig — convenience EnvConfig subclass with common fields (port, debug, logLevel, database, JWT, CORS); extend to add project-specific fields.
• Add loadEnvFile / mergeEnv — .env file parsing utilities.
• Add shelf_router and shelf_cors_headers as package dependencies.

0.0.27

• Upgrade lints from ^5.0.0 to ^6.1.0; fix unnecessary_underscores lint in tests (__ → _)

0.0.26

• Fix compressionMiddleware: responses below the compression threshold had their body stream silently consumed and then returned unmodified — shelf would throw "read method can only be called once" when it tried to send the response. Now rebuilds the response with the already-buffered bytes via response.change(body: bytes).

0.0.25

• ApiRoute handler now passes pre-built shelf.Response objects through unchanged — enables SSE (sseResponse()) and file-download handlers to be used with typedHandler

0.0.24

• Add DartApiTestClient — in-process test client that calls a Shelf Handler directly (no TCP socket); exposes get, post, put, delete, patch and TestResponse with .json<T>()
• Add LogFormat enum (text | json) to loggingMiddleware — JSON mode emits structured log lines with timestamp, level, method, path, status, duration_ms, and request_id (when requestIdMiddleware has run)
• Add metricsMiddleware() — records http_requests_total and http_request_duration_seconds histograms per (method, path, status) in a singleton MetricsRegistry
• Add MetricsController — exposes GET /metrics in Prometheus text format (0.0.4); register via app.enableMetrics()

0.0.23

• Add cacheTtl: Duration? to ApiRoute — opt-in per-route response caching without touching global middleware
• Add ApiRoute.effectiveMiddlewares getter — returns [cacheMiddleware(ttl: cacheTtl), ...middlewares] when cacheTtl is set; used by RouterManager
• Update cacheMiddleware docstring with per-route usage examples

0.0.22

• Add ValidationException — carries a list of {field, message} errors for multi-field validation failures
• Add Map.validateAll(fields) — runs all field validations, collects every failure, then throws ValidationException with the full list (instead of stopping at the first error)
• ApiRoute handler now catches ValidationException before ApiException and returns {"errors": [...]} with status 422

0.0.21

• Add timeoutMiddleware(Duration) — returns 408 if handler exceeds the timeout
• Fix: null handler result now returns 204 No Content instead of throwing a 500
• Improve loggingMiddleware output: [timestamp] METHOD /path STATUS 12ms — removed emoji, added response duration

0.0.20

• Fix: _serialize now handles bool and num responses — returning a bool from a handler no longer throws a 500 "Unable to serialize" error

0.0.19

• Add test/base_controller_test.dart — routes getter, webSocketRoutes default, route callability
• Add test/logging_middleware_test.dart — pass-through behaviour, method coverage, pipeline composition
• Extend test/api_route_test.dart — per-route middleware: ordering, short-circuit, header injection

0.0.18

• Add EnvConfig base class — typed env var access (env, envInt, envDouble, envBool) with injectable environment map for testing
• Add MissingEnvException and InvalidEnvException
• Add HealthController — exposes GET /health returning {"status":"ok","uptime":"..."}

0.0.17

• Fix: use super parameters in NotEmptyValidator and UrlValidator (linter cleanup)

0.0.16

• Add MinLengthValidator, MaxLengthValidator, NotEmptyValidator, RangeValidator<T extends num>, PatternValidator, UrlValidator
• Add Pagination — extracts ?page and ?limit from a request with clamping; computes offset
• Add PaginatedResponse — Serializable wrapper that includes a meta block (page, limit, total, totalPages, hasNext, hasPrev)
• Add SseEvent and sseResponse() for Server-Sent Events streaming

0.0.15

• Add header<T>() extension on Request for typed header extraction (case-insensitive)
• Add CookieRequestExtensions — request.cookies map and request.cookie(name) for reading cookies
• Add setCookie() helper for attaching Set-Cookie headers to responses (supports maxAge, path, domain, sameSite, httpOnly, secure)
• Add cacheMiddleware — in-memory GET response cache with configurable TTL and custom key extractor; adds X-Cache: HIT/MISS headers

0.0.14

• Add multipartFiles(), file(), formFields() extensions on Request for multipart/form-data parsing
• Add UploadedFile with bytes, filename, contentType, text, and isFile
• Add BackgroundTaskQueue, backgroundTaskMiddleware(), and Request.backgroundTasks for post-response async work
• Add WebSocketRoute for WebSocket endpoints alongside HTTP routes
• BaseController now has webSocketRoutes (default empty list)
• New dependencies: mime, shelf_web_socket, web_socket_channel

0.0.13

• Add rateLimitMiddleware — token-bucket rate limiter keyed by IP (or custom key); returns 429 with Retry-After and X-RateLimit-* headers
• Add requestIdMiddleware — attaches X-Request-Id to every request/response; propagates existing IDs; stores ID in request.context['requestId']
• Add compressionMiddleware — gzip-compresses responses above a configurable threshold when client sends Accept-Encoding: gzip

0.0.12

• Improve README: update version snippet, improve formatting

0.0.11

• Fix type-mismatch error message in verifyKey: now uses friendly JSON type names (string, integer, number, boolean) instead of Dart type names

0.0.10

• Swagger UI: bearerAuth security scheme is now always present in the spec so the Authorize button always appears
• Swagger UI: persistAuthorization: true — entered tokens survive page refreshes (stored in localStorage)

0.0.9

• Add OpenApiGenerator — generates an OpenAPI 3.0 spec from a list of ApiRoutes
• Add DocsController — serves GET /openapi.json, GET /docs (Swagger UI), GET /redoc (ReDoc)
• Add SecurityScheme enum with bearer value; ApiRoute now accepts security: [SecurityScheme.bearer]
• Add contentType field on ApiRoute (default 'application/json'); used for HTML doc routes
• Add tests for all new OpenAPI types (23 additional tests)

0.0.8

• Expand test suite: comprehensive tests for ApiRoute, RequestExtensions (pathParam/queryParam), MapExtensions, and globalExceptionMiddleware

0.0.7

• Add pathParam<T>() extension on Request for typed path parameter extraction
• Add queryParam<T>() extension on Request for typed query parameter extraction with optional default values
• Add statusCode field on ApiRoute (default 200) for custom success response codes (e.g. 201, 204)
• Add globalExceptionMiddleware for app-level exception handling

0.0.6

• Add ApiException class for returning specific HTTP error status codes from handlers and validators
• Fix FormatException (malformed JSON body) now returns 400 Bad Request instead of 500
• Fix validation errors from verifyKey() now return 422 Unprocessable Entity instead of 500
• ApiException is exported from the package

0.0.5

0.0.4

0.0.3

• Add Email Validator

0.0.2

• Add Middelware
• Add Validators
• Enhance Key Verification with Validators
