The Node.js-based Reddit Shorts Video Generator is an application designed to produce brief video content by extracting top comments from a Reddit post and generating corresponding screenshots and text-to-speech (TTS) audio for each comment. Initially, I developed an npm package for generating short videos, which later evolved into a Node.js application that includes an API and a user interface created with Express and React. Due to the reliance on multiple dependencies for environment configuration, I opted to containerize the application using Docker.
During the development journey, I encountered several challenges. First, I needed to expand my understanding of Docker and configure the environment for it. Furthermore, I had to set up Redis queues, even though they were not ultimately utilized. Lastly, I had to initiate a child process in Node.js to execute a task in the background.
