object-path-set

Description

set values in javascript objects by specifying a path.

if the path doesn't exist yet, it will be created.

by using this library, you can help prevent the following error from occurring:

Cannot set property 'foo' of undefined

NOTE: I've re-written / used this function so many different times, I decided to publish it as a module.

Getting Started

Install the module with: npm install --save object-path-set

var setPath = require('object-path-set');
var obj = { foo: { bar: 'baz' } };
obj = setPath(obj, 'foo.bar', 'newValue'); // result: {foo:{bar:'newValue'}}
obj = setPath(obj, 'foo.invalidKey', 'cool'); // result: {foo:{bar:'newValue',invalidKey: 'cool'}}
obj = setPath(obj, 'foo|bar', 'again', '|'); // result: {foo:{bar:'again',invalidKey: 'cool'}}
