v8client

Documentation

Overview

Package v8client is a client for submitting jobs to the v8server. The purpose of this package and the v8server package is because embedding v8 into your Go binary takes too much time, so we instead communicate back with the embedded V8 in the bud binary during development. When building, we embed V8 directly because builds can afford to be slower.
