  • TSDBot: A Java-based Discord Chat Bot

    This project is a chat bot for Discord written in Java. It has a number of features:

    1. Easily-extensible array of "functions" ranging from trivial (e.g. replacing some of the text in a previous message and returning the result) to more complicated (e.g. picking a random line from the chat history and sending it in a tweet to the community manager of the video game developer Bungie)

    2. Integration with AWS, specifically S3 and EC2

    3. Via Dropwizard, implements an embedded Jetty server for serving HTTP requests including a navigable website

    4. Implements a streaming, broadcasting media service that is integrated with the Discord chat and the hosted website. This service is modeled on a "job polling" framework, where the streaming media are actually stored on separate machines alongside a standalone "agent" executable JAR. This agent sends periodic heartbeats to the Discord bot communicating which videos it has available. The Discord bot can display this video catalog to users. If a user wants to play any video, the Discord bot will place a "job" in its queue for the specific agent, and the next time the agent sends a heartbeat it will receive the "play this video" job and will begin streaming the video
