V8 Bindings for Go

Usage

To use import v8:

import (
  v8 "github.com/grexie/go-v8"
)

See the v8_isolate_test.go file for a basic example of how to setup a v8.Isolate, v8.Context, create values and run JavaScript code. For more detailed API information see GoDoc.

Copyright

Substantially based on the great work by Augusto Roman (@augustoroman):

github.com/augustoroman/v8

I've added native promises, JSON stringify / parse, value caching, weak callbacks, function templates and constructors, v8 Inspector and a terminal-based allocation tracer api for debugging.

Thanks be to God for the help He has given me in writing this.

Bugs

Please open an issue to report a bug. Before opening a new issue please see if there are already issues matching your case.

Installation

For now, please follow his instructions for installation of the v8 libraries and headers:

https://github.com/augustoroman/v8

There's a script included install-v8.sh that can be used to install the version of libraries this library is developed against for both ARMv6 and AMD64 (linux and macOS):

./path/to/behrsin/go-v8/install-v8.sh

This will download the binaries and install them into the go-v8 folder under libv8/ and include/.

Debug

There is a heap tracing tool which monitors active V8 objects referenced by Go. To use it look at StartTracer and EnableAllocationStackTraces. You can mount TracerHandler() using a net/http.(*ServeMux) to enable the stack traces over HTTP or you can use v8.DumpTracer to writer the trace output to a log file or os.Stdout periodically.
