Deploying a Deep Learning Image Classification Model with NodeJS, Python, and Fastai

TL|DR: Use this to easily deploy a FastAI Python model using NodeJS.

You've processed your data and trained your model and now it's time to move it to the cloud.

If you've used a Python-based framework like fastai to build your model, there are several excellent solutions for deployment like Django or Starlette. But many web devs prefer to work in NodeJS, especially if your model is only part of a broader application.

My friend Navjot pointed out that NodeJS and Python could run together if we could send remote procedure calls from NodeJS to Python.

Context

Reverse Proxy?

• Node and Apache are not mutually exclusive. Apache (or NGINX if preferred) can be set up as a reverse-proxy for the Node server. This means that requests would go to Apache first, then forwarded on to the Node server.
  • Reasoning for this can be found: https://linuxtogether.org/configuring-reverse-proxy-for-node-using-apache-mod-proxy/

Or just use Node

• We had the opportunity of setting up a fresh Digital Ocean server running CentOS 7, and opt'd for this for simplicity and for the fun experience of learning how to set up a fresh CentOS 7 Server to be used with the MERN stack.
• In our scenario, Node can listen on port 80 and we should be good to go...
