Library Dependencies

Last Updated: 12/11/2016

These are the modules we depend on, with their corresponding minified or unminified sizes:

| Library | Link | Minified Size | Purpose | Should Remove? | | ------------- |:-------------:| -----:| | EventEmitter | Link | 2.91 KB | Provides OneSignal.on and OneSignal.once event listener methods. | Yes, we should switch this out to es6-emitter so we don't have to use heir below maybe. | | Heir | Link | < 3.62 KB (unminified) | Our classes have to inherit the event emitter class in order to use .on() and .once(). Maybe this would go away if we switched to es6-emitter? | Yes | | loglevel | Link | 2.34 KB | Separates logging by levels. | No, works well, super small. | | js-cookie | Link | 3.59 KB | Simplifies cookie management with Cookie.get() and Cookie.set(). | No, probably not, not too big. | | bowser | Link | 6.46 KB | Browser detection. Use like bowser.chrome == true or bowser.samsungBrowser. | Yes, this could all be replaced with a very simple regex detection like we had originally. | | object-assign | Link | 2.01 KB | Ponyfill for Object.assign(), which is not implemented in all browser. | Yes, this is basically a utility function we could just call instead. No need for ponyfill detection. | | swivel | Link | 4.06 KB | Allows message passing between Service Worker and host page. | No, not yet, although this library had to be patched a bit, for now it still works, maybe we can replace it later. | | es6-error | Link | 2.64 KB | Allows inheriting from the Error object correctly. | No, works, is small. | | Validator/isUuid | Link | 0.88 KB | Checks if something is a valid UUID. | No, works well, very small. |

Total: 28.51 KB (minified + non-minified, so not quite summable)
