Add-on infrastructure

[wwahammy (Eric)]

So I was looking through the source and I realized that I really like the add-on infrastructure. It seems like it’d very useful to other Node projects who want functionality for add-ons. Is this add-on system based on a more general library? Or is there interest in moving it into a more general library?

Thanks!

It’s already somewhat modular, but I’m open to hearing ways we could improve. Right now, we have the following:

• The gateway’s built-in plug-in IPC:
  • https://github.com/mozilla-iot/gateway/tree/master/src/plugin
• Bindings for Node.js and Python add-ons:
  • https://github.com/mozilla-iot/gateway-addon-node
  • https://github.com/mozilla-iot/gateway-addon-python
• The add-on list itself, along with a validator:
  • https://github.com/mozilla-iot/addon-list
• An add-on builder, which cross-compiles for Linux, macOS, Linux on ARM (Raspbian), and OpenWrt:
  • https://github.com/mozilla-iot/addon-builder
• A proxy server, which reads URL parameters and returns the add-ons which apply to the user’s platform:
