Validate Time

NPM version Build Status Coverage Status Dependencies

OpenTSDB utility providing time validation.

OpenTSDB allows three time formats. This library exposes an API to validate time values in accordance with the allowed formats.

Install

For use in Node.js,

$ npm install opentsdb-validate-time

For use in the browser, use browserify.

Validate

To create an OpenTSDB time validator,

var validate = require( 'opentsdb-validate-time' );

The validator is exported as a class instance (in Node, as a singleton) and has the following methods...

validate.absolute( date )

Validates whether an input string is an absolute date; e.g., 2014/07/18-9:34:42. An absolute date is formatted according to the following rules:

  • year, month, and day are separated by /: year/month/day
  • calendar values are separated from temporal values by either a space or -: year/month/day-00:00:00 or year/month/day 00:00:00
  • if specified, hour and minutes must be specified together: 00:00
  • seconds are optional
validate.absolute( '2014/07/14' );
validate.absolute( '2014/07/14 9:23' );
validate.absolute( '2014/07/18-9:34:42' );

validate.timestamp( timestamp )

Validates whether an input value is a timestamp. A timestamp may be either in seconds or milliseconds.

var timestamp = Date.now();
 
validate.timestamp( timestamp );
validate.timestamp( Math.round( timestamp/1000 ) );

validate.relative( time )

Validates whether an input string is a relative time. Relative times have a time unit (ms, s, m, h, d, w, n, y) and the suffix -ago.

validate.relative( '72000ms-ago' );

Note: the unit for months is n.

validate.format( time )

Returns an input value's time format.

validate.format( '2014/07/18-9:34:42' );
// returns 'absolute'
 
validate.format( Date.now() );
// returns 'timestamp'
 
validate.format( '72000ms-ago' );
// returns 'relative'
 
validate.format( 'beep' );
// returns undefined

Examples

To run the example code from the top-level application directory,

$ node ./examples/index.js

Tests

Unit

Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

$ make test-cov

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

$ make view-cov
