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 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 following will create a solutions/01 directory and place all necessary files there.

bun scaffold 1

Solving Each Day

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

bun solve 1

You can pass a --debug or -d flag to launch the Bun web debugger.

bun solve 1 -d
