Build

# first, prepare mruby (we embed it by default)
# NOTE: Might require running with sudo, since we build artifacts within a Go module
make prepare-mruby

# then build the Go binary (will be available in dist/anycable-go)
make

You can run tests with the following commands:

# Run Golang unit tests
make test

# Run once
make prepare

# Run integrations tests
make test-conformance

# Run integration benchmarks
go install github.com/anycable/websocket-bench@latest
make benchmarks

We use golangci-lint to lint Go source code:

make lint
