Project Structure

Solutions are located in ./src/year/day/:

• README.md: puzzle description
• input.txt: my puzzle input
• index.ts: solution
• index.test.ts: jest tests

Usage

Solve

To run a solution for a specific day of the current year, run npm run solve <day>, replacing <day> with the particular puzzle you want to run, e.g. npm run solve 10. To run a solution for a previous year, use <year>/<day>, e.g. npm run solve 2021/10.

Update

To use the update command, retrieve the value of your session cookie from https://adventofcode.com and enter it in .env under the SESSION_ID= key. The command will fetch any missing descriptions or inputs for the current year. If either README.md or input.txt exists for a specific day, those files will be skipped. External requests are throttled to one request every 2 seconds.

Description HTML responses are cached to ./cache/<year>-<day>.html. To force it to be retrieved again, e.g. to fetch the description for part 2, the file must be deleted manually.
