nested-observe

Object.observe() for nested objects.

Compatability

nested-observe internally uses WeakMap (for garbage collection). Node.js supports both WeakMap and Object.observe since version 0.11.13. For browsers have a look at: kangax's compaitibility table. For unsupported browsers/Node.js, you can use shims, e.g. KapIT/observe-shim and Benvie/WeakMap.

Api

var Nested = require('nested-observe') // window.Nested when using browser bundle
Nested.observe(root, callback, accept)
Nested.unobserve(root, callback)
Nested.deliverChangeRecords(callback)

Delivered change records contain two additional properties:

• root - the root of the nested structure
• path - a JSON Pointer (absolute from the root) to the changed property

Debugging

By default, Object.observe ignores errors occuring during change record delivery. To simplify debugging, you can set Nested.debug = true, which will log such errors to the console.
