♟️ Lichess-Discord-Bot 💻

About

• This is a discord bot that posts chess puzzles from lichess in an interactive manner.

• This bot is currently hosted on my raspberry pi and you can add it to your discord server here

Tech stack & improvements

• The application is currently written in typescript with a sqlite3 database and is currently running in docker containers on a raspberry pi 3, any improvements are welcome, just make a PR. If you encounter any issues also feel free to make a issue here on github.

Technical details

• !puzzle grabs a random lichess puzzle between ids 1-120000
• Each running instance of this bot (currently just my own) will at most make one request per puzzle to the lichess servers in an attempt to not be annoying and spammy, if you delete the sqlite3 db you'll need to make additional requests for puzzles you've already served before.
• More to come...

Commands

• !puzzle
• !move a1a2
• !help

How to Run

Docker

Warning The current base images are design for ARM based processor architectures e.g raspberry pis, if you are planning on running this project on another processor architecture you have two options

1. Update the base image of the Dockerfile in this repository e.g change the line FROM node:13.14-buster as compiler and create your own lila-gif docker image that uses a different base image (or you can bug me and I'll make one)
2. Don't run this project in docker and instead follow the Non-Docker steps

Docker steps

• Make sure you have docker and docker-compose https://docs.docker.com/get-docker/
• Clone this repository
• Create a .env file by copying the .env.sample file
• Fill in discord bot token with your own discord application key, and set LILA_HOST=lilagif as we have lila-gif in a container
• Build a local docker image for the discord bot via docker build -t lichess-bot .
• Run the discord bot and lila-gif server via docker-compose up --build

Note - if you plan on altering any files you will need to rebuild your local docker image via docker build -t lichess-bot . and then bring up the containers again to see any changes

Non-Docker

• Make sure you have typescript https://www.typescriptlang.org/
• Clone this repository
• Create a .env file by copying the .env.sample file
• Fill in discord bot token with your own discord application key, and set LILA_HOST=localhost
• Run npm install
• Run nodemon, this starts the discord bot service and will reload the service when any .ts file has been changed
• Clone the lila-gif repository https://github.com/niklasf/lila-gif
• Make sure you have rust https://www.rust-lang.org/tools/install
• Run cargo build
• Run cargo run
