NodeJS Holochain Conductor.

Wraps the rust conductor in node.

Installation

Uses Holonix: https://github.com/holochain/holonix

Requires nix-shell same as Holochain Core (native or VM).

holochain-nodejs's Issues

Windows travis build

CI does not generate binaries for windows. Travis supports building rust projects under windows but the build script does not run correctly

Set up simple test runner for master branch and PRs, only do binary builds for Tags

Add tests for rust and js

If this is to become part of holochain cmd it must be robust.

• Rusts test should be added to the native code
• js tests (tape?) should be used to ensure the module works
• All tests should be run by the CI

`npm run install` fails with "neon.o: No such file or directory"

I've searched around for similar errors and this seems related: neon-bindings/neon#186. It's due to node-gyp, but I don't know how to diagnose this since this issue was from a year and a half ago.

Full error output:

Add fallback to build from source

When attempting to install from npm on a platform for which there are no binaries the library should use neon build to attempt to build from source
