This a library that expose some ramda helpers
With yarn
yarn add ramda-helpersWhit npm
npm install --save ramda-helpersYou have to import helpers like any other ES6 module
import ramdahelper from 'ramda-helpers'
ramdaHelper.isNilOrEmpty(null) //=> truereturns a list without falsy values
Parameters
Array
Examples
compact(['', 'test', 0, undefined, null]) //=> ['test']Returns Array
Sort desc a list of nested object by a prop
Parameters
Examples
descOrderBy('a', [{ a:1, b:2 }, { a:2, b:1 }]) //=> [{ a:2, b:1 }, { a:1, b:2 }]Returns Array
Retrieve the value at the given path
Parameters
Examples
getPath('a.b.c', { a: { b : { c : 'value' } } }) //=> 'value'
getPath(['a', 'b', 'c'], { a: { b : { c : 'value' } } }) //=> 'value'
getPath(['a', 'c', 'd'], { a: { b : { c : 'value' } } }) //=> undefinedReturns any The data at path
Returns true if prop is a Array
Parameters
valueany
Examples
isArray(() => {}) //=> false
isArray({}) //=> false
isArray([]) //=> trueReturns Boolean
Returns true if prop is a function
Parameters
valueany
Examples
isFunction({}) //=> false
isFunction(() => {}) //=> trueReturns Boolean
- See: isPathSatisfied if you want to test nested object
Test if value is NilOrEmpty
