- MutationObserver abstraction using Kefir streams for added, removed and attribute modified elements
- Useful for writing browser extensions
- It's not meant to be a general purpose tool for any environment. This is useful for existing Kefir projects, otherwise it's like using 10kb of js to just watch for dom mutations.
- Single page apps are everywhere, one can't just listen to
DOMContentLoadedto to start working with document contents. - Because MutationObservers are pretty uncomfortable to work with.
- Handling async data is suitible for streams
- To play with latest es6 syntax I guess.. idno..
Exposes the obsAdded, obsRemoved and obsAttributes for creating streams
Creates a stream emitting nodes already added and newly added nodes which
matches selector for aslong as the stream has subscribers.
If subtree is set, nodes matching selector added to anywhere in the subtree
of root will be emitter.
Creates a stream emitting nodes removed from root which matches selector
for aslong as the stream has subscribers. If subtree is set, nodes matching
selector removed from anywhere in the subtree of root will be emitter.
Creates a stream emitting root when an attribute matching attributeFilter
(optional) is changed for as long as the stream has subscribers.
