🌟Private Leaderboard Discord Bot for Advent of Code 🌟

This is a simple Discord bot written in JavaScript for Node.js that posts to a Discord channel when the stars or the score on a private leaderboard have changed. The bot will call on boardProcessor.js to go through the fetched leaderboard json files and make a message about changed points, positions, stars and star gain times since the last fetch of the leaderboard json file. That message - together with a link to the leaderboard page and a short summary - is then posted to the discord channel by discordNotifier.js.

No fancy integrations, just using Discord client for posting the messages.

Prerequisites

• Node v10+
• Tested on Windows 10(node v14), repl.it(node v12), and Rasperry Pi OS ( Raspberry Pi Zero, node v10)

How to use

• run npm install
• Fill in the config.json file with discord bot info and aoc leaderboard info, or put the variables in the environment or in a .env file.
• Optionally tweak the flags at the top of boardProcessor.js to your preferences
• Run npm run start
• Kill the process if you wanna stop the bot

Try it out in your Browser now!

I uploaded this project to repl.it and verified it is working fine there from the browser. You can run it directly by going here: https://repl.it/@francisduvivier/aoc-discord-notifier-bot. You need to fork it there and create a .env file in order to pass the config data (required environment variable names and values are exactly the same as the config.json file). You should know though that saving leaderboard files to disk is disabled on repl.it by default. So every time the program is restarted, the whole leaderboard will be seen as new in the first check.

Miscellaneous

You can also update the .replit file to delete the files on every boot. To do that, add onBoot="rm -f data/*.json" in the .replit file.
