JS Object Keys Mapper

Changes object keys maintaining the same values using read() and write() methods or creates new keys manipulating object data.

Installation

You'll need bower to install JS Object Keys Mapper library and its dependencies Install the library and save it as a dependency in your project:

$ bower --save install js-object-keys-mapper

Usage

Let's suppose to have the following object:

var obj1 = {
	text: "This is a text",
	rows: 5,
	isVisible: true
}

we need to create a new object with differnt keys but with the same values or similar as follows:

var result = {
	data: "This is a text",
	numberOfRows: 5,
	isHidden: false
}

Here you are the solution: instanciate a new ObjectKeysMapper as follows:

var mask = {
	read: {
		data: 'text',
		numberOfRows: 'rows',
		isHidden: function(obj) {
			return !obj.isVisible;
		}
	},
	write: {
		// NOTE: not needed for this example
	}
};
var mapper = new ObjectKeysMapper(mask);
var result = mapper.read(obj1);

Development

The project has the following structure:

dist/
		*.min.js // The uglified version of the component.
src/
		*.js // The source file
test/
		src/*.test.js // Tests
		...						// Task runner configuration file and test dependencies

Installation

This project requires node for the development installation so you can install its dependencies, build it and test it.

Please run following commands to install all dependencies:

$ npm install

• jshint: Validate files with JSHint.
• uglify: Create the final *.min.js.
• usebanner: Prepends a banner to the minified file
• watch: Run default task when src or test files are added, changed or deleted.
• emptyTheChangelog: Truncates the CHANGELOG.md file as conventionalChangelog task will append fully regenerated changelog
