v8host

Documentation

Overview

The v8host packages provides functionality to execute client-side scripts in gost-dom. The engine uses v8, and requires cgo.

This engine is based on tommie's v8go form, which automatically pulls the latest v8 changes from the chromium repo.

An alternate script engine that is implemented in pure go is found in the gojahost package
