Utility for setting/getting/manipulating deeply nested attributes of an object or array.
npm install node-objectifyThis node library allows you to set, get or check for the predicate of a
deeply nested objects.
It lets you avoid patterns such as:
``javascript`
if (myObj.options && myObj.options.site && myObj.options.site.url) {
// do something with myObj.options.site.url
}
And it helps you avoid the popular undefined is not a function error.
`javascript
var objectify = require('objectify');
var src = {};
`
Check for the existence of a nested attribute:
`javascript
if (objectify(src).isSet('a.very.deeply.nested.attr')) {
// true or false
// do something with the nested attr here
console.log(src.a.very.deeply.nested.attr);
}
`
Getting a long nested attribute:
`javascript
src = {a: {very: {deeply: {nested: { attr: 1 }}}}};
objectify(src).get('a.very.deeply.nested.attr'); // returns 1
objectify(src).get('a.non.existant.attr'); // returns undefined
`
Setting a deep nested attribute:
`javascript
objectify(src).set('a.different.nested.attribute', 2); // returns 2
console.log(src.a.different.nested.attribute) // 2
