This will load the folder test/chrome-app as an unpacked extension in chrome. Test currently designed for windows and Mac Canary support for others accepted


The following permissions need to be added to your chrome packaged app for this module.

The chrome apis do not support sync calls for some of the corresponding features so the calls have been made async.

Currently these are

  1. cpus(callback(cpuinfo))

  2. platform(callback(platform)) The platform string maps to the expected node value.

There is currently a console warning and 'Not Supported' is returned if these functions are called without a callback. It should be noted that browserify doesn't fully support these either only returning placeholders. If users are interested in full cross platform support then an async-os implementation could be implemented.
