$ lichess-tournament-creator file my_tournaments.json

JSON tournaments file format

The JSON tournaments input file should follow the following format:

{
    "auth_token": "authtokenxpto123",   // lichess API authorization token, used in all requests
    "tournaments": [
        {
            "name": "First anual chess meetup",
            "type": "arena",
            "date": "2021-01-01 16:30:00",
            "tournament_duration": 80,
            "match": {
                "duration": 3,
                "increment": 2
            }
        },
        {
            "name": "Swiss-cheese open",
            "type": "swiss",
            "team_id": "switzerland-chess-club",
            "date": "2021-05-20 15:10:00",
            "num_rounds": 7,
            "match": {
                "duration": 5,
                "increment": 3
            }
        }
    ] 
}

Usage considerations

• The Lichess API only allows a limit of tournaments created per user, per day (12 public tournaments or 24 private tournaments)
• The generated authorization should feature permission for tournament creating
• In order to create a swiss format tournament for a team, the user must be an admin of the team (to have the required permissions)

Tests

To run the test suite, install the project's dependencies and run npm test:

$ npm install
$ npm test

Future work

• Allows public/private tournament specification, along with other tournament-tweaking options that are not available at the moment
• Improve error lichess API error handling, displaying it in a more user-friendly format
