The nice javascript library to rubynize your javascript to be a happy programmer again.
This library is mainly intended for those who are familiar with programming with Ruby and miss some convenience features in Javascript. It's time to be happy again!
On the one hand it contains extensions and patches for core classes (e.g. String),
on the other hand it provides (extended) wrapper classes in Ruby style,
e.g. File with File.write().
It is available for the browser as well as for NodeJS.

ruby for javascript, ruby methods for javascript, ruby functions for javascript
The javascript method names are ported to a javascript equivalent by the following rules and always written
in camelCase:
| Description | Ruby code | JavaScript code |
|---|---|---|
Question mark methods are ported to isMethod |
File.exist?File.directory? |
File.isExisting()File.isDirectory() |
Getters are ported to getMethod getMethod |
File.basename |
File.getBaseName() |
Verbs and transformation methods starting with 'to' are only ported to camelCase |
MyClass.destroy_objectMyClass.to_hash |
MyClass.destroyObject()MyClass.toHash() |
Loops should start with for, but they would collide with java script methods, e.g. forEach()In cases of collissions, the orignal ruby name remains if possible. Some other cases have new names. |
[].each / [].each_with_index |
[1,2,3].eachWithIndex() |

In your project root directory execute the following command:
yarn add ruby-niceIn your project root directory execute the following command:
npm install ruby-niceDownload the latest release on Github or the from the folder dist and put it in an appropriate folder of your project, e.g. js/lib
and reference it by a script tag in your project:
<script type="text/javascript" src="js/lib/ruby-nice.bundle.js"></script>Optionally you may add the source file to your build pipeline, if you are using webpack, brunch or any other packager.
As ruby-nice depends on Typifier, there is also a bundle release called ruby-nice.bundle.js where the latter is included. If you already use Typifier separately, use the default version ruby-nice.js without included dependencies. If you don't know what you should use, use the bundled release!
If you prefer minified builds, use the *.min.js version. Be aware that they do not contain any javascript documentation that may be very useful when working with a powerful IDE.
