This is a minimal binding between Go (golang) and V8 JavaScript. Basic concept is to only expose two methods to JavaScript: send and receive.

V8 Version: 6.9.427.19 (August 2018)

A rather dated presentation on this project

Due to the complexity of building V8, this package is not buildable with go get.

To install:

go get github.com/ry/v8worker2
cd `go env GOPATH`/src/github.com/ry/v8worker2
./build.py # Will take ~30 minutes to compile.
go test

If you have ccache installed, ./build.py --use_ccache will take advantage of it. This is useful to avoid rebuilding V8 so much.

The JavaScript interface is exposed thru a single global namespace V8Worker2. The interface has just three methods V8Worker2.print(), V8Worker2.send(), and V8Worker2.recv(). See v8worker2.d.ts for the details.

Documentation is at https://godoc.org/github.com/ry/v8worker2 and example usage is at worker_test.go

• The original v8worker passed strings between Go and V8. v8worker2 instead communicates using ArrayBuffer, which is more efficient.

• The original included recvSync and sendSync methods. These were deemed unnecessary. Now send() can operate both sychronously by returning another ArrayBuffer. Simply return a []byte from the golang recv callback.

• This version is compatible with modern V8, has a better build setup, and uses Travis for CI.

• The original prefixed the methods with dollar signs, this version uses a global name space object and provides a typescript declaration file.
