Access values in nested properties and arrays using a keypath.
Easily access properties in nested objects and arrays using a dot notation syntax.
Install with NPM:
$ npm install keypath
Keypath only exposes one function, so require it and use it.
var keypath = require('keypath'); keypath('foo.bar.baz', object);
Keypath takes 2 or 3 arguments.
keypath: a string representing the value you want to access.
object: the object in which this value resides.
callback/rethrow: an optional argument that can be either a function or
true. If you give it a function, this function will be called if an error occurs. The error itself will be the callbacks only argument.
If you pass
trueany error will be re-thrown and you can catch it yourself.
If left out
keypath()will just return
I'd like to add setting, that'd be convinient, right? Also adding
the like would be cool. If you don't know what that is read this
excellent blogpost about
that feature in Cocoa.
