Here are some useful links and information to help you to continue to explore Node-RED and TensorFlow.js.

Node-RED Resources

  • You can find a complete copy of the Node-RED project this workshop creates here.

    This includes the flow file you can import if you want to skip to the end.

  • Alternatively, you can access the final flow from this repository here.

  • For more information about using Node-RED, start with the Node-RED Essentials playlist on YouTube.

  • The Working with Messages section of the documentation provides a good introduction to understanding the structure of a message.

  • The Flow Developer Guide provides lots of useful information on best practices in creating flows. It covers how to layout your flows, how to structure your messages and also how to properly document your flows (something this workshop hasn't really touched on).

  • The Node-RED community forum is a great place to get help, as is the project's Slack.

TensorFlow.js Resources

  • You can find out more about TensorFlow.js at its site here

  • We've used the Object Detection model in this workshop. For more information about other pre-trained models that are available, check out this page.

  • To use a different model, you'll need to change over to the node-red-contrib-tf-model set of nodes. Make sure you read its documentation before installing it as you have to manually install the TensorFlow libraries first.

    You should not try installing it at the same time as the node-red-contrib-tfjs-coco-ssd module we've used in this workshop.
