Changed #

• BREAKING: Renamed maxAttempts to maxRetries in ViaRetry. Now 0 means no retries (clearer semantics).
• BREAKING: Renamed onStream to onResultStream in ViaPipeline for consistency with onResult.

Fixed #

• Debounce Cleanup: Fixed potential memory leak in ViaDebouncePipeline when requests fail or throw exceptions.

Docs #

• Added warning about retry not working with streaming request bodies (Stream<List<int>>).

Changed #

• Pipeline Architecture: Refactored ViaPipeline for better type safety and clarity.
  • onResult now specifically handles ViaResult (buffered responses).
  • onStream now receives the full ViaResultStream object instead of raw stream chunks, allowing access to response metadata (headers, status code) during streaming.
• Enhanced Streaming: Added ViaResultStream.copyWith to allow pipelines to transform response streams while preserving metadata.
• Improved Validation: ViaResponseValidatorPipeline now supports validation of both buffered and streaming responses.

Fixed #

• Map Body Casting: Fixed an issue where Map payloads with non-string values (like int or bool) would cause a type cast error. They are now automatically converted to strings for form-data requests.

Changed #

• Modernized Syntax: Fully adopted Modern Dart enum member access (e.g., .network instead of ViaError.network).
• Simplified Examples: Consolidated multiple example files into a single, clean example/main.dart.
• Unit Tests: Added a comprehensive suite of unit tests with real network request validation.

Fixed #

• Pipeline Error Handling: Fixed an issue where onError was not being called on pipelines when a request failed.
• Logger Stream Support: Added stream error tracking to ViaLoggerPipeline via onStream interception.

Changed #

• Architecture Refinement: Simplified internal request handling by returning ViaBaseResult from worker and handling type casting in ViaMethods. This provides better flexibility for custom result types (like SotyResult) used with pipelines.

Fixed #

• Type Safety: Fixed a critical type 'ViaResult' is not a subtype of type 'R' in type cast error in ViaMethods. Both Via.worker and ViaMethods._request are now generic to correctly handle custom result types.

Changed #

• Simplified API: Removed ViaExecutor class. All execution logic (pipelines, retry, runner) has been moved directly into the Via class for a cleaner and more intuitive API.
• Truly Pure Dart: Removed the flutter SDK dependency. The library is now a pure Dart package, compatible with CLI, Server-side, and Flutter.
• HTTP Focus: Removed internal WebSocket support to keep the library lightweight and focused on HTTP.
• Auto-mapping Support: Added to<T> and toListOf<T> methods to ViaResult for seamless JSON-to-Model conversion.
• Stream Body Support: Enhanced Via to support Stream<List<int>> as a request body.
• Dedicated Streaming API: Introduced via.stream() method which returns Future<ViaResultStream>. This allows accessing status codes and headers before consuming the response stream.
• Internal Refactoring: Organized source files into a flatter, more logical structure.

Fixed #

• Isolate Stability: Explicitly detaching the request object from the response before returning from an isolate. This prevents "Illegal argument in isolate message" errors caused by unsendable ByteStream references in MultipartRequest.
• Auto Isolate Bypass: Added automatic Isolate bypass for requests containing Stream bodies or CancelTokens.

Changed #

• API Simplification: Removed ViaCall wrapper. Standard HTTP methods now return Future<ViaResult> directly.
• Dedicated Streaming API: Introduced via.stream() method which returns Future<ViaResultStream>. This allows accessing status codes and headers before consuming the response stream.

Added #

• Fluent API with ViaCall: Introduced ViaCall which implements Future, allowing direct await via.get() while providing a .stream getter for byte streaming.
• Streaming Response Support: Added real-time byte streaming with .stream getter on any request.
• Improved Result Buffering: ViaResult now handles lazy buffering, allowing both streaming and future-based body access on the same result.
• Pipeline onStream Support: Added onStream hook to ViaPipeline for intercepting or transforming data chunks in real-time without blocking the stream.
• New Example: Added example/stream_response.dart to demonstrate the new streaming capabilities.

Changed #

• Modern Dart Syntax: Adopted modern Dart enum member access (e.g., .get instead of ViaMethod.get).
• Isolate Safety: Refactored ViaResult to be isolate-friendly by lazily initializing non-sendable fields like Completer.
• API Cleanup: Removed redundant isStream flags and explicit via.stream() methods in favor of the more intuitive .stream getter on any call.

Added #

• Multipart Upload Support: Dedicated via.multipart() method for form-data and file uploads.
• WebSocket Support: Introduced ViaSocket for lightweight and flexible WebSocket connections.
• WebSocket Pipelines: Added ViaSocketPipeline for intercepting lifecycle events.
• WebSocket Auto-Reconnect: Support for autoReconnect and reconnectDelay.
• Smart URI Conversion: Automatic http/https to ws/wss conversion.
• Examples: Added multipart_example.dart.

Changed #

• API Simplification: Shorthand methods (post, put, patch, delete) now only handle standard bodies. All file uploads must use via.multipart().
• Internal Refactoring: Moved HTTP methods to ViaMethods mixin and organized pipelines into src/features/pipelines/.
• Removed part/part of structure in favor of standard imports.

Changed #

• Refactored HTTP methods to use the ViaMethod enum for better type safety and consistency.
• Updated ViaRequest.toCurl() and ViaRequest.toString() to correctly use enum values.
• Internal cleanup of method parameter types across the library.

Changed #

• Internal cleanup: Removed redundant generic type parameters from ViaExecutor and ViaRetry.
• Simplified internal execution flow by centralizing type casting in the Via class.
• Improved code maintainability by reducing generic boilerplate in core feature classes.
• Updated all examples to support sequential execution via Future<void> main().
• Improved example/main.dart to act as a comprehensive test runner for all features.
• Enhanced example/pipeline.dart with a custom logger for better visibility.

Fixed #

• Further improved toCurl character escaping by using single quotes for headers and URL to prevent shell interpretation issues.
• Fixed toJson in ViaResult to correctly handle null-aware response properties.
• Added response object to ViaException in ViaResponseValidatorPipeline for better debugging.

Fixed #

• Fixed toJson and toCurl implementations in ViaRequest.
• Improved cURL command generation with better character escaping for terminal compatibility.
• Fixed ViaException JSON serialization by correcting null-aware syntax.
• Adopted modern Dart null-aware map entries syntax (?variable) for cleaner metadata.

Changed #

• Refactored ViaPipeline to be non-generic for better flexibility and simplicity.
• Removed generic requirements from all built-in pipelines (ViaLoggerPipeline, ViaCachePipeline, etc.).
• Simplified custom result transformation by removing covariant complexity in favor of standard inheritance.

Added #

• Initial release of the Via HTTP engine.
• Via class for high-level HTTP operations.
• ViaExecutor with support for ViaPipeline architecture.
• Built-in resilience with ViaRetry (automatic retries).
• Request cancellation support via CancelToken.
• Type-safe JSON parsing helpers (asMap, asList).
• Memory-managed ViaCachePipeline (FIFO with maxEntries).
• Advanced pipelines: ViaLoggerPipeline (with cURL support), ViaDebouncePipeline, ViaThrottlePipeline, and ViaResponseValidatorPipeline.
• Connection pooling support with shared http.Client.
• Isolate-based execution support for background processing.
• errorIf validation in ViaExecutor to treat HTTP responses as errors (defaults to non-2xx).
