A single-file zero-overhead C++ idiomatic wrapper for the native WebGPU C API, providing syntactic sugar without runtime cost.
WebGPU-C++ is a single-file, header-only C++ wrapper for the native WebGPU C API. It provides an idiomatic C++ interface to WebGPU—a modern, cross-platform graphics and compute API—by adding syntactic sugar like namespaces, object methods, and scoped enums, all with zero runtime overhead. It solves the problem of verbose and error-prone C-style WebGPU code, making it more concise and natural for C++ developers.
C++ developers working with graphics, GPU compute, or cross-platform rendering who are using or evaluating the native WebGPU API (via backends like wgpu-native, Dawn, or Emscripten) and want a more modern, less verbose coding experience.
Developers choose WebGPU-C++ because it dramatically reduces boilerplate and improves code readability when using WebGPU's native C API, without introducing any runtime performance penalty. Its zero-overhead guarantee, automatic generation from official headers, and optional separate RAII wrapper offer flexibility and safety while staying true to the raw API's semantics.

Maintains full performance parity with the raw C WebGPU API, as the wrapper is designed to avoid any hidden behavior or memory layout changes, ensuring no performance penalty.
Transforms verbose C-style calls into modern C++ with namespaces, object methods, and scoped enums, significantly improving code readability and reducing boilerplate, as shown in usage examples.
Provides setDefault() methods and Default constructors for descriptors, sourced from the WebGPU specification, which cuts down on repetitive initialization code without runtime cost.
Replaces C-style callbacks and void* userdata with C++ lambdas that can capture context, simplifying asynchronous operations like buffer mapping, as demonstrated in the README.
Requires careful version matching between pre-generated headers and WebGPU backends, with potential need for custom generation using Python scripts, adding setup complexity and risk of mismatches.
As a zero-overhead wrapper, it introduces no additional error checking or validation beyond the raw WebGPU API, leaving developers to handle low-level errors and resource leaks manually.
RAII functionality is isolated in a separate webgpu-raii.hpp file, requiring an extra include and complicating adoption for those wanting automatic lifetime management without modifying the core wrapper.
