Advent of Code

This is my personal playground for advent of code, implemented in typescript.

One Time Setup

  1. Clone this repo git clone https://github.com/sdg9/AdventOfCode
  2. Install dependencies npm i
  3. To automate reading of your Advent Of Code puzzle input create a .env file at the root of this project with the value session=<your advent of code session cookie value>. Then when you generate each day's script it will pull in your associated puzzle input.

How to Generate a new day

  1. Ensure one time setup is complete
  2. Run npm run generate and follow the prompts, or run npm run generate <year> <day>, e.g. npm run generate 2021 01 for day 1 of 2021.

Now you can work on src/<year>/<day>/index.ts and src/<year>/<day>/input.txt should be populated with your puzzle input for the day (if input.txt only contains the text error make sure your .env file is properly configured).

Execute your script

  1. Run npm run dev src\<year>\<day> e.g. npm run dev src\2021\01 for day 1 of 2021

This will also enter watch mode so that whenever a code change happens the script executes again.

e.g.

➜  AdventOfCode git:(main) npm run dev src/2021/01

> node-proxy@1.0.0 dev
> nodemon "src/2021/01"

[nodemon] 2.0.4
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): src/**/*
[nodemon] watching extensions: ts
[nodemon] starting `ts-node src/2021/01`
Time: 0.335ms
Solution to part 1: 1342
Solution to part 2: 1378
[nodemon] clean exit - waiting for changes before restart

and then on edit of a file

[nodemon] restarting due to changes...
[nodemon] starting `ts-node src/2021/01`
Time: 0.338ms
Solution to part 1: 1342
Solution to part 2: 1378
[nodemon] clean exit - waiting for changes before restart

Preferred IDE

Unsurprisingly I use VSCode

  • I recommend the Prettier - Code Formatter plugin. If it's not formatting on save try "Shift + Alt + F" and typically you'll presented with a prompt on what plugin you want to use to format, choose this prettier plugin. From here on out every time you save a file it should auto format according to your prettier config.
