Development

To develop node-irsdk itself, you need working working installation of node-gyp.

Useful commands:

  • npm install builds binary addon
  • npm run ready runs tests and updates docs

Making a new release

  1. Check if license file needs updating
  2. npm run ready
  3. Tag new version using npm version, push to Github
  4. Wait for Appveyor to upload binaries
  5. npm publish
  6. Add release notes to Github, helper npm run release-notes.
