Build live comments with sentiment analysis using Nest.js
Interestingly, one of the most important areas of a blog post is the comment section. This plays an important role in the success of a post or an article, as it allows proper interaction and participation from readers. This makes it inevitable for every platform with a direct comments system to handle it in realtime.
In this post, we’ll build an application with a live comment feature. This will happen in realtime as we will tap into the infrastructure made available by Pusher Channels. We will also use the sentiment analysis to measure whether comments are positive or negative, and display this information on an admin panel.
