getter

Helper for adding getters and setters into your object. For node and browser.

Installation

For node.js:

npm install getter

For browser you need to include lib/getter.js into your page. Getter is AMD-friendly.

Usage

All you need to do is to pass an object and options to mixin function. Getter will create getters and setter for you:

var getter = require('getter');
var obj = {};
 
getter.mixin(obj, {
    foo: 'bar',
    baz: 1
});
 
console.log(obj.getFoo()); // "bar"
 
obj.setBaz(2);
console.log(obj.getBaz()); // 2

You can easily override default getters and setters:

var getter = require('getter');
var obj = {};
 
getter.mixin(obj, {
    foo: {
        value: 'bar',
    
        getter: function () {
            return this.foo + this.foo
        },
 
        setter: function (val) {
            this.foo = val + val;
        }
    }
});
 
console.log(obj.getFoo()); // "barbar"
 
obj.setFoo('x');
console.log(obj.getFoo()); // "xxxx"

If you don't want to create getter of setter for property, you can always get rid of it:

var getter = require(getter);
var obj = {};
 
getter.mixin(obj, {
    foo: {
        value: 'bar',
        setter: false
    }
});
 
console.log('setFoo' in obj); // false

Tests

For Node.js tests:

grunt test

For all tests (buster and phantomjs must be installed globally):

grunt buster
