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
recvSyncandsendSyncmethods. These were deemed unnecessary. Nowsend()can operate both sychronously by returning another ArrayBuffer. Simply return a[]bytefrom 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.
