This repository contains solutions and visualizations for Advent of Code 2023 event implemented in TypeScript (mostly Node.js + browser-based visualizations).
The only requirement the build and run the code is Node.js v20.x or later.
To begin, clone the repository and run the following command to install dependencies:
npm ciThe you can use the following commands:
| Command | Description |
|---|---|
npm run node-start -- ./src/puzzle{NN}.ts |
Run solutions for day NN |
npm run node-build |
Test if everything compiles without errors |
npm run browser-serve |
Run local web server with visualizations for some puzzles |
npm run browser-build |
Build static resources to deploy visualizations on e.g. GitHub pages |
Each solution expects the input data at input/puzzleNN.txt from the repository root. If needed, test data can be provided via input/puzzleNN_test.txt and changed in the source to use a different file.
Some solutions will write additional output for debugging or simple visualization means into output/puzzleNN* files (the directory will be crated if necessary).
The repository contains launch configuration for Visual Studio Code debugger at .vscode/lunch.json such that each puzzle solution can be launched separately with debugger attached just by opening the solution source and selecting Run > Start Debugging or pressing F5 (with default keybindings).
