MeasurementJs

Code Climate Build Status devDependency Status

Nice unit of measure conversion, featuring:

  • Simplicity: an easy to-use, Behaviour driven API
  • Sophistication: Coverage Status full test coverage from project day one
  • Quality: aiming at high performance whilst maintaining a fair trade-off between accuracy
  • Adaptability: Easy to extend for new measurement types (incl. i18n tables)
measurement('Temperature').convert(20)
    .from(measurement.Unit.Temperature.CELSIUS)
    .to(measurement.Unit.Temperature.FAHRENHEIT);        // returns 68

measurement('Distance').convert(1)
    .from(measurement.Unit.Distance.KILOMETRE)
    .to(measurement.Unit.Distance.METRE);                // returns 1000
    
measurement('Speed').convert(10)
    .from(measurement.Unit.Speed.KILOMETRE_PER_HOUR)
    .to(measurement.Unit.Speed.METRE_PER_SECOND);       // returns 2.7777777777777777

Test-Driven Development

The API definition and all conversion operations are covered by jasmine tests. The test suite can be executed straightaway and easily, for example:

  • Test directly in the browser Simply open test/index.html in the browser

  • PhantomJs via Karma test driver npm run-script karma That command is just a shorthand for node_modules/.bin/karma start. If you have karma-cli already installed globally, you can also just do karma start. Karma will startup and run all tests on phantomjs

  • Any Browser you like with Karma

    1. Set singleRun:false in ./karma.conf.js
    2. Start the Karma with npm run-script karma or npm test or ... (see above)
    3. navigate any browser you'd like to test to http://localhost:9876
    4. observe the output on the test console
