How to deploy model using node js

I created a recommendation system using lightFM on Google Colab. I want to deploy this model using Node JS. I read this [article](https://www.geeksforgeeks.org/how-to-deploy-a-machine-learning-model-using-node-js/) and tried the method recommended here. It recommended using tensorflow.js. For that the model needed to be saved and this is where the problem arose since I wrote my model using lightFM.

This gave rise to following error:
`
AttributeError Traceback (most recent call last)
in
----> 1 model.save("model.h5")

AttributeError: 'LightFM' object has no attribute 'save'
`

What is the alternative to model.save in lightfm? How can we deploy model written in lightfm using node js?

Start by reviewing LightFM's model serialization capabilities and the linked Node.js deployment approach. Determine whether a supported export or interoperability path is required for deploying a LightFM model in Node.js; done would mean a documented, reproducible deployment path.
