WebAssembly for Proxies (Go SDK) Build License

The Go SDK for Proxy-Wasm, enabling developers to write Proxy-Wasm plugins in Go. This SDK is powered by TinyGo and does not support the official Go compiler.

Getting Started

  • examples directory contains the example codes on top of this SDK.
  • OVERVIEW.md the overview of Proxy-Wasm, the API of this SDK, and the things you should know when writing plugins.

Requirements

  • TinyGo - This SDK depends on TinyGo and leverages its WASI (WebAssembly System Interface) target. Please follow the official instruction here for installing TinyGo.
  • Envoy - To run compiled examples, you need to have Envoy binary. We recommend using func-e as the easiest way to get started with Envoy. Alternatively, you can follow the official instruction.

Installation

go get github.com/tetratelabs/proxy-wasm-go-sdk

Build and run Examples

# Build all examples.
make build.examples

# Build a specific example.
make build.example name=helloworld

# Run a specific example.
make run name=helloworld

Compatible Envoy builds

Envoy is the first host side implementation of Proxy-Wasm ABI, and we run end-to-end tests with multiple versions of Envoy and Envoy-based istio/proxy in order to verify Proxy-Wasm Go SDK works as expected.

Please refer to workflow.yaml for which version is used for End-to-End tests.
