Fight your chess addiction without stop playing (limit Chess.com and Lichess daily games)

ChessBlocker

ChessBlocker is a chrome extension that limits the number of chess games you play per day on Chess.com and Lichess.

Installation

Install via the extension page.

Development

1. Clone/Download the project
2. Setup node and build
   • npm i
   • npm run build
3. Go to chrome://extensions/
4. Click on "Load unpacked" and select the dist folder
5. Configure your username in the options page

How it works

• The user configures his username in the extension settings, and the number of games permitted to play every day.
• When browsing chess.com or lichess website, the extension adds a handler to every button that starts a new game. In that handler, the extension checks with chess.com or lichess API that the user didn't reach the current day limit, including games from other browsers or mobile.

Known Issues

• Chess.com API supports only getting a user's games from the whole last month. This data can take a few seconds to retrieve, which can delay the button click.
• The games data for a user can take a few seconds to update in Chess.com server, so sometimes when starting a new game, the previous game won't be counted if ended very recently.
• If limiting to more than 20 games a day, fetching games from lichess can take more time since they limit the speed to 20 games per second.

TODO

• Convert to TypeScript
• Prettier settings page UI
• Prettier limit page UI
• Prettier popup
• Restriction based on game type (blitz, bullet...)
• Add browser based counting (instead of always using chess.com or lichess API)
• Request from chess.com API to get games per day instead of per month
• Use dialog inside tab instead of opening a new tab when game limit is reached (when chrome API allows)
