Set up a new day:

Run day solutions:

Run day solutions in dev mode (without clearing console outputs):

For automatic puzzle input retrieval, define .env file with session cookie from adventofcode.com:

Generated day structure:

import { parseLines, readInput } from 'io'

const input = await readInput('day-01')

export const part1 = () => {
  const lines = parseLines(input)
  // your code goes here
  return lines.length
}

Expected index.ts solution structure (day 1 of 2022):

import { parseGroups, readInput } from 'io'
import { desc, sum } from 'utils'

const input = await readInput('day-01')

export const part1 = () => {
  const lines = parseGroups(input, Number)
  return lines.map(sum).sort(desc).at(0)
}

export const part2 = () => {
  const lines = parseGroups(input, Number)
  const top = lines.map(sum).sort(desc).slice(0, 3)
  return sum(top)
}

bun day <day-num> output:

🌲 Part One: 70698 (1.11 ms)
🎄 Part Two: 140471 (383.5 µs)
