An asset beautifier for node.js

Node-Beautify

Node-Beautify is a node.js module that can be easily required and used to beautify assets from within a Node.js script. It is not meant to be a command-line tool, there are plenty of existing tools for that. The purpose of Node-Beautify is for javascript based build scripts or the like that want to be able to 'require' a beautifier module. Currently it only supports javascript. The original intent was to encapsulate additional syntax support, such as css. I may still do that at some point, but if you would like to add another formatting parser in the meantime, feel free to fork this repo and send a pull request.

Installation

npm install node-beautify

Usage

to beautify javascript:

    require('node-beautify').beautifyJs(source, options);

where source is a string of javascript source code and options (optional) allows overriding the defaults (see below)

Default Options

• indentSize : 4
• indentChar : ' ' (space character)
• preserveNewlines : true
• bracesOnOwnLine : false
• keepArrayIndentation : false
• spaceAfterAnonFunction: true
• indentLevel : 0

Example

// require the module
var nb = require('node-beautify');

// pass a string of ugly javascript to the beautifyJs method
var prettyJs = nb.beautifyJs("function test(){console.log('test');}");

// the results should be a nicely formatted javascript string
console.log(prettyJs);

To run tests

Mocha should be installed globally. If it is not, you can install it by typing

npm install mocha -g

Clone the repository using git, e.g.

git clone https://github.com/fshost/node-beautify

After the repo has been cloned, in the repo directory type

npm install

After all dependencies are installed, the tests can be run by typing

mocha
