Advent of Code 2023

🎅 Solutions for Advent of Code 2023 written in TypeScript.

I'm using Bun this year. Find instructions to install the Bun executable here.

Set Up

Install the dependencies using Bun.

bun install

Create a .env file at the root that contains your Advent session cookie. You can find this cookie value by inspecting the network request made to https://adventofcode.com/2023/day/DAY_NUMBER/input in the browser.

# .env

ADVENT_SESSION=YOUR_SESSION_COOKIE

Scaffolding Each Day

I've provided a scaffold package.json script that will set up the files needed for solving both parts for each day, as well as pulling your unique input. It will output them in a solutions/DAY_NUMBER directory.

The first argument should be the day number and the remaining arguments should be the words in the day's title. The title argument is optional.

# The following will create a solutions/01 directory and place all necessary files there.
# It will also replace the recap.md title placeholder with "The First Day"

bun scaffold 1 The First Day

Solving Each Day

Run the solve package.json script to execute the solution code for a given day.

bun solve 1
