An important aspect of running a Twilio Live streaming experience is to track your viewership. But how do you do that? There are many different ways to do it, and the best method to use will depend on your needs and your technology stack.

Are you ready to learn how to count your livestream viewers? In this article I’ll show you a few possible implementations with varying levels of complexity and flexibility.

Requirements

This article does not have any requirements beyond having some familiarity with the Twilio Live product. If you haven’t worked with Twilio Live before, I recommend that you follow an introductory tutorial first. My colleague Mia Adjei wrote a Twilio Live tutorial using Express.js, and I have also written one using the Twilio serverless platform, both of which show you how to build a complete livestreaming project step by step.

Object detection is a computer vision technique for locating instances of objects in media such as images or videos. This machine learning (ML) method can be applied to many areas of computer vision, like image retrieval, security, surveillance, automated vehicle systems and machine inspection.

Recently I was developing a CLI in Node.js that would help make the process of writing articles in Markdown easier for my team. The flow required that a local .md file be parsed, formatted, converted to .docx, and then uploaded to Google Drive as a Google Doc file, all by running one command from the terminal.

I approached this project in a few different ways, hoping initially that I could use serverless functions to handle the backend. I hit a lot of dead ends on this route, and eventually decided to build an Express server that I would ultimately host on Heroku.

To upload the .docx file contents from my CLI to a secure backend endpoint, where it would then be uploaded to the user’s authenticated Google Drive, I needed a way to POST multipart/form-data directly from Node.js (without a browser). This requires several third party libraries, and it …
