Once again I'm trying to solve Advent of Code in Elm, hopefully managing to solve more puzzles than in 2019. :-)
You can try the solution on your own inputs here: https://aoc2020.konstenius.se/
Your puzzle inputs should be placed as files in the folder ./static/input/. On file per day named <day>.txt.
Example:
$ ls ./static/input/
1.txt 2.txt 3.txt 4.txt 5.txt 6.txt 7.txt
Install dependencies and run the application.
npm install && npm run dev
Now point your browser to http://localhost:8000 and click on the numbered buttons to run each days solution.
Have fun.
