Attr

Build Status

A basic getter/setter mixin that abstracts accessing a data map.

Special thanks to @Krisk for the NPM package name.

Installing

Using npm: npm install attr --save

Latest code can be found here: https://github.com/Macrofig/attr

Usage

import Attr from 'attr';
 
const myObj = { name: 'Juan' };
const attr = new Attr(myObj);
 
attr('name'); //> 'Juan'
attr('name', 'Optimus Prime'); //> 'Optimus Prime'
attr(); //> { name: 'Optimus Prime' }

or

NOTE: It is not recommended to append to the Object prototype. This is just a simple example on how to attach attr to your custom class.

import Attr from 'attr';
 
const myObj = { name: 'Juan' };
Object.prototype.attr = Attr();
 
myObj.attr('name'); //> 'Juan'
myObj.attr('name', 'Optimus Prime'); //> 'Optimus Prime'
myObj.attr(); //> { name: 'Optimus Prime' }

Build

The code is in ES6 but it can be transpiled into AMD, CommonJS, or global modules. If you are using the NPM package, the dist is already available to you.

  • Clone to your machine: git clone https://github.com/Macrofig/attr
  • cd attr
  • npm install
  • Run the build npm run build

This will create a dist folder with three bundles, one for each of the following:

  • AMD
  • CommonJS
  • Global

Use the appropriate bundle as needed. :)

Tests

Make sure you have installed the dependencies (see "Build" above) and have Firefox installed on your machine.

Command line:

Simply run npm run test.

This will run tests using Firefox so make sure it is installed first.

Browser:

Simply run npm run develop. This will attempt to start a web server on port 8001, if successful, it will open your default browser.

Browse to /tests.html. Tests will run in the Mocha browser using StealJS and Testee.

Future

  • Test coverage
  • Better documentation
  • Access deep properties with . (dot) operator. myObj.attr('name.last')
  • Hookable getter/setter. Create any plugin needed to change getter or setter behavior.
  • Get multiple items by passing array (filter): myObj.attr(['name', 'npm']);//> {name: 'Juan', twitter: 'macrofig'}
