WebAssembly for Proxies (C++ SDK)

Proxy-Wasm is a specification and supporting framework for using WebAssembly (Wasm) to extend the functionality of network proxies. It enables developers to write custom logic (plugins) that are compiled to Wasm modules and then loaded and executed by the proxy.

Proxy-Wasm consists of multiple parts:

• An ABI that specifies the low-level interface between network proxies and Wasm virtual machines that run the plugins.
• Host implementations of the ABI, provided by network proxies.
• Language-specific SDKs that layer on top of the ABI, providing a more natural and programmer-friendly API for invoking and implementing Proxy-Wasm functions and callbacks.

This repository provides the C++ SDK.

Getting started

• Read the API overview to learn about Proxy-Wasm concepts and how they are represented in the C++ SDK.
• View an example plugin.
• Refer to API documentation.
• Build plugin code.
