Utilities

You can install using npm and require to use in node.js

var bbu = require('@hishprorg/perspiciatis-ratione-unde');

var ob = bbu.object;         // object library
var obs = bbu.object;        // objectset library
var arrs = bbu.arrayset;     // arrayset library
var dtt = bbu.datetime;      // datetime library

The following methods are provided

object Library

Provides utility methods for objects.

exists(obj)

Checks if obj is not undefined or null

var r0 = ob.exists(null);
var r1 = ob.exists(undefined);
var r2 = ob.exists('anything else');

console.log(r0); // false
console.log(r1); // false
console.log(r2); // true

objectset Library

Provides utility methods that modify an object.

objectset.compact(obj)

Recursively removes all null and undefined values from obj. No special handling is done for resulting empty objects or arrays

var obj = {
  a: 1,
  b: null,
  c: {
    d: undefined,
    e: 4
  },
  f: {
    g: null
  }
};

obs.compact(obj);
console.log(obj); // {a: 1, c:{e:4}, f:{}}

arrayset Library

Provides utility methods that modify an array.

append(arr, arrToAppend)

Appends arrToAppend elements to arr

var arr = ['a', 'b'];

arrs.append(arr, ['c', 'd']);
console.log(arr); // ['a', 'b', 'c', 'd'];

datetime Library

Provides conversion methods to/from blue-button-model datetimes from/to ISO datetimes.

datetime.dateToModel(d)

Converts ISO date d to blue-button-model datetime

var r0 = dtt.dateToModel('2014');
var r1 = dtt.dateToModel('2014-02');
var r2 = dtt.dateToModel('2014-02-07');
var r3 = dtt.dateToModel('2014-02-07T12:45:04.000Z');

console.log(r0); // {date: '2014-01-01T00:00:00.000Z', precision: 'year'}
console.log(r1); // {date: '2014-02-01T00:00:00.000Z', precision: 'month'}
console.log(r2); // {date: '2014-02-07T00:00:00.000Z', precision: 'day'}
console.log(r3); // {date: '2014-02-07T00:00:00.000Z', precision: 'day'}

datetime.dateTimeToModel(dt)

Converts ISO datetime d to blue-button-model datetime

var r0 = dtt.dateTimeToModel('2014');
var r1 = dtt.dateTimeToModel('2014-02');
var r2 = dtt.dateTimeToModel('2014-02-07');
var r3 = dtt.dateTimeToModel('2014-02-07T12:45:04.000Z');

console.log(r0); // {date: '2014-01-01T00:00:00.000Z', precision: 'year'}
console.log(r1); // {date: '2014-02-01T00:00:00.000Z', precision: 'month'}
console.log(r2); // {date: '2014-02-07T00:00:00.000Z', precision: 'day'}
console.log(r3); // {date: '2014-02-07T12:45:04.000Z', precision: 'second'}

Millisecond piece is ignored even when it is not zero.

datetime.modelToDate(dt)

Converts blue-button-model datetime dt to ISO date

var r0 = dtt.modelToDate({
  date: '2014-01-01T00:00:00.000Z',
  precision: 'year'
});
var r1 = dtt.modelToDate({
  date: '2014-02-01T00:00:00.000Z',
  precision: 'month'
});
var r2 = dtt.modelToDate({
  date: '2014-02-07T00:00:00.000Z',
  precision: 'day'
});
var r3 = dtt.modelToDate({
  date: '2014-02-07T12:45:04.000Z',
  precision: 'second'
});

console.log(r0); // '2014'
console.log(r1); // '2014-02'
console.log(r2); // '2014-02-07'
console.log(r3); // '2014-02-07'

datetime.modelToDateTime(dt)

Converts blue-button-model datetime dt to ISO datetime

var r0 = dtt.modelToDateTime({
    date: '2014-01-01T00:00:00.000Z',
    precision: 'year'
});
var r1 = dtt.modelToDateTime({
    date: '2014-02-01T00:00:00.000Z',
    precision: 'month'
});
var r2 = dtt.modelToDateTime({
    date: '2014-02-07T00:00:00.000Z',
    precision: 'day'
});
var r3 = dtt.modelToDateTime({
    date: '2014-02-07T12:45:04.000Z',
    precision: 'second'
});
var r4 = dtt.modelToDateTime({
    date: '2014-02-07T12:45:04.010Z',
    precision: 'second'
});


console.log(r0); // '2014'
console.log(r1); // '2014-02'
console.log(r2); // '2014-02-07'
console.log(r3); // '2014-02-07T12:45:04.000Z'
console.log(r4); // '2014-02-07T12:45:04.010Z'
