Weeb Logger

Weeb Logger is a JS Canvas component for logging on devices that are problematic to use debugging tools (specially if you are using some external framework for developing those ahead) like Samsung Tizen, LG webOS or Chromecast. Plus you can customize it with your favorite waifu! :3

Installation

Use your favorite package manager, mine is:

yarn add @bsartori/weeb-logger

Usage

import logger from '@bsartori/logger';

logger.configure({
  enabled: true,
  visual: true,
  enableStackTrace: true,
  containerStyle: {
    position: 'bottom-left',
    width: 800,
    height: 800,
    opacity: 1,
    lineHeight: 20,
  },
  waifu: {
    name: 'alya',
    useTheme: true,
    showWaifu: true,
  },
});

logger.info('SOME LABEL', 'A string or object here!');
logger.warn('WARN', 'This is an warning');
logger.error('Api Error', 'This is an error');
logger.success('JSON', { lorem: 'ipsum', dolor: {
  sit: 'amet'
}});
logger.highlight('IMPORTANT', 'This is an highlight info');
try {
  throw new Error('I can also log Error objects!');
} catch (error: any) {
  logger.error('ERROR OBJECT', error);
}

On DevTools this will result in:

Log in DevTools

And in your application:

Log in DevTools

You can also resize the container:

API

Configuration Object

  • enabled: Boolean (default: true) - Set to false to completely disable weeb-logger
  • visual: Boolean (default: true) - Set to false to only disable visual container (logging on DevTools or node cmd will still work)
  • formatStackTrace: Boolean (default: true) - Uses stacktrace.js to format error stacktraces when the log message is an instance of Error. This way stack traces will show original files rather than bundled files. It makes HTTP requests to sourcemaps.
  • containerStyle: Object(IWeebLoggerContainerStyle) - Container style configuration object.
    • width: Number (default: 800) - Width of the container.
    • height: Number (default: 800) - Height of the container.
    • position: TWeebLoggerContainerPosition (default: 'bottom-right') - Available values: top-right, top-left, bottom-right and bottom-left.
    • opacity: Number (default: 1) - Decrease this value if you want to see content that is below the visual container.
    • *lineHeight: Number (default: 20) - Line height for log messages on the visual container.
  • waifu: Object(IWeebLoggerWaifu) - Waifu configuration object.
    • showWaifu: (default: true) - Set to false to remove Waifu image.
    • name: (default: 'tohka'): Selects waifu to display. Available values: akeno, alya, aqua, ayano, darkness, koneko, masha, megumin, tohka, yuki, zerotwo.
    • useTheme: (default: true) - Uses Waifu theme style, set to false to use default theme style.

yarn test

Please make sure all tests pass before submiting a PR

Log in DevTools

Roadmap

Would love Pull requests that build towards these objectives and even ideas for new objectives :3

  • Decrease package size (As waifu images increase, we'll need to store them on a CDN or something like that) Solved by using GitHub URL to the raw image LOL
  • Configure ESLint
  • Improve README.md
  • Tests
    • Resize (aparently jest-dom doesn't support getting element dimensions)
    • !isNode (maybe find another way to determine if environment is nodejs or browser other than typeof process === 'object' && `${process}\` === '[object process]')
  • Add a CI pipeline that runs the tests
  • Add more waifus! It would be very cool if some artist drew them for us :heart_eyes:
  • Log levels
  • Increase customization options
  • Organize this mess I call code :laughing:
