How to Build

We compile these plugins targeting WebAssembly WASIP1.

Build via standard Go:

# Build jwt-auth
GOOS=wasip1 GOARCH=wasm go build -o jwt-auth.wasm ./plugins/jwt-auth/main.go

# Build pii-scrubber
GOOS=wasip1 GOARCH=wasm go build -o pii-scrubber.wasm ./plugins/pii-scrubber/main.go

Build via TinyGo:

tinygo build -o jwt-auth.wasm -target=wasi ./plugins/jwt-auth/main.go
