Util functions and classes
- Expose some Lodash functions
- Exports additional helpers
The main inspiration on my work is PHP Laravel Framework which I love because of its simplicity and beauty of code.
First of all I created this to support development of Kernel Framework.
Just like the rest of the packages that make up the framework, I make the most of other existing libraries that are well
tested on a day-to-day basis. The idea is not to reinvent the wheel, just join the ideas in a lightweight framework
(the focus is on the client side), simple to use and make the code on the front more beautiful and organized.
npm install @kernel-js/support

Gets the value of an environment variable.
env(key, [defaultValue])
Arguments
key
- the path to the property you want. You can use dot notation on nested objectsdefaultValue
- the optional default value when the key was not found
// Examples
env('NODE_ENV');
env('app.name');
env('app.name', 'My Default App Name');
Return a boolean if the informed value is of Array type.
isArray(value)
Arguments
value
- any value
// Example
isArray([]); // True
isArray({}); // False
isArray(''); // False
Return a boolean if the informed value is of Object type.
isObject(value)
Arguments
value
- any value
// Example
isObject({}); // True
isObject([]); // False
isObject(''); // False
Check if the informed value is empty. This is a little different of lodash behaviour,
booleans are not considered empty and ' ' for example is considered empty.
isEmpty(value)
Arguments
value
- any value
// Examples
isEmpty(true); // false
isEmpty(null); // true
isEmpty(undefined); // true
isEmpty(' '); // true
isEmpty({}); // true
isEmpty([]); // true
Just the oposite of isEmpty.
isNotEmpty(value)
Arguments
value
- any value
// Examples
isNotEmpty(true); // true
isNotEmpty(null); // false
isNotEmpty(undefined); // false
isNotEmpty(' '); // false
isNotEmpty({}); // false
isNotEmpty([]); // false
Converts a give string or number into boolean or return null when cannot convert it.
toBoolean(value)
Arguments
value
- any value
// Examples
toBoolean(1); // true
toBoolean('true'); // true
toBoolean('yes'); // true
toBoolean('on'); // true
toBoolean(0); // false
toBoolean('false'); // false
toBoolean('no'); // false
toBoolean('off'); // false
toBoolean('lorem ipsum'); // null
Removes any empty property from object using isEmpty helper.
removeEmpty(value)
Arguments
value
- any object
// Example
removeEmpty({"a": " ", "b": "b value", "c": null}); // {"b": "b value"}
Converts any empty property of object to null using isEmpty helper.
mapEmptyToNull(value)
Arguments
value
- any object
// Example
mapEmptyToNull({"a": " ", "b": "b value", "c": null, "d": {}}); // {"a": null, "b": "b value", "c": null, "d": null}
