Nous Utils and Helpers for Meteor

We're using a few helpers and utils in many our apps. Here are a few most used of them.

Helpers

• isEq val1 val2 -> e.g. {#if isEq 'a' value} ... {/if}
• isIn val array -> e.g. {#if isIn 'a' array} ... {/if}
• oneOf val1 val2 -> {#if oneOf good bad} Show message if good or bad are true {/if}
• formatDate datetime, format -> will return given date in selected format
  • compact: "DD.MM"
  • short: "DD.MM.YYYY"
  • long: "DD MMMM YYYY (ddd)"
  • txt: "DD MMM"
• monthByNumber month -> e.g. {{monthByNumber 1}} will return "January"

For Arrays

• arr.unique -> returns array of uniq values or arr
• arr.merge(arr2) -> merge two arrays
• arr.exclude(element) -> will not touch original array, return array without element
• arr.remove(element) -> will remove element from original array
• arr.clean() -> will delete all undefined elements from array

Property

Sometimes we want to use some function as property, e.g.

class Foo
  @property onePlusTwo: -> "Result is #{1+2}"

x = new Foo
alert(x.onePlusTwo) # Will alert "Result is 3", don't need to call onePlusTwo() function

Operation with Strings

• srt.capitalize -> will capitalize given string (first letter will be capitalized)
