gin-gonic/gin

This system is a Go web framework that provides a unified engine for binding and validating HTTP requests across numerous data formats, including JSON, XML, and Protocol Buffers. It features a pluggable JSON codec layer for performance optimization, built-in renderers for responses like BSON and PDF, and utilities for efficient memory handling. The framework also supports global server management, static file serving, and comprehensive testing infrastructure.

Added a new internal \fs\ package that provides a \FileSystem\ type wrapping \http.FileSystem\ to implement the \fs.FS\ interface, allowing standard library file system operations to work with HTTP file systems. Included unit tests to verify correct file opening and error propagation.

The internal/bytesconv package now provides StringToBytes and BytesToString functions that convert between strings and byte slices without memory allocations by using unsafe operations. This allows applications to perform these conversions more efficiently, avoiding the overhead of copying data. The package also includes comprehensive tests and benchmarks to verify correctness and performance against standard conversion methods.

The repository has been initialized with essential configuration files, including a \.gitignore\ to exclude vendor and IDE artifacts, a \.golangci.yml\ to enforce linting and formatting standards (such as \gofumpt\ and \usestdlibvars\), and a \.goreleaser.yaml\ to automate release processes. Additionally, documentation files like \BENCHMARKS.md\ and \CHANGELOG.md\ have been added to track performance metrics and version history.

The ginS package provides a global, singleton-based HTTP server API for Gin, allowing users to register routes and start the server using simple package-level functions (e.g., ginS.GET, ginS.Run) without explicitly managing an engine instance. This release adds support for the HTTP QUERY method (RFC 10008) via a new ginS.QUERY shortcut, and includes comprehensive tests covering all HTTP methods, middleware, routing groups, and static file serving.

The render package now supports two new response formats. Users can return BSON data using the new \BSON\ struct, which marshals data via \go.mongodb.org/mongo-driver/v2/bson\ and sets the \application/bson\ content type. Additionally, a \PDF\ struct has been added to allow returning raw PDF binary data with the \application/pdf\ content type. These additions expand the built-in serialization options available in the framework.

The JSON codec layer now supports runtime selection of different JSON libraries via build tags. Users can switch the underlying JSON encoder/decoder from the standard library to high-performance alternatives like \github.com/goccy/go-json\, \github.com/json-iterator/go\, or \github.com/bytedance/sonic\ by enabling specific build tags (\go\_json\, \jsoniter\, \sonic\). This allows for performance optimization or specific behavioral requirements without changing application code, as the \codec/json\ package abstracts the implementation behind a common \Core\ interface.

The binding package now provides a comprehensive, unified interface for binding HTTP request data (JSON, XML, form, multipart, query, URI, headers, plain text, YAML, TOML, BSON, and Protocol Buffers) to Go structs, along with integrated validation. Users can bind various content types using dedicated instances like \JSON\, \Form\, \Query\, and \ProtoBuf\, with automatic content-type detection via the \Default\ function. The system supports advanced features such as default values for form fields, custom validation tags via the \go-playground/validator/v10\ engine, and flexible mapping for embedded structs, pointers, and slices. Additionally, the binding layer now handles multipart file uploads, allows ignoring fields, and supports custom unmarshalers for complex types, ensuring robust and consistent request data processing across the application.

The example code has been removed from this repository and relocated to a separate standalone repository. A new README in the examples directory now directs users to the new location, ensuring they can still access the sample code (such as basic routing and authentication examples) from the correct source.

New test data files have been added to support unit testing of specific features. This includes a self-signed certificate and private key in \testdata/certificate/\ for TLS-related tests, a Protocol Buffers definition and generated Go code in \testdata/protoexample/\ for serialization tests, and sample template files (\hello.tmpl\, \raw.tmpl\) in \testdata/template/\ for template engine tests. A plain text file was also added in \testdata/\ to support file serving tests.
