angular-snapscroll adds vertical scroll-and-snap functionality to angular.
- JS-only implementation
- Only requires angular core

Install with bower:
bower install angular-snapscroll
Or with npm:
npm install angular-snapscroll
The pre-built files can be found in the
dist/angular-snapscroll.min.js is minified and production-ready. Example usage:
<script src="angular-wheelie/dist/angular-wheelie.min.js"></script> <script src="angular-scrollie/dist/angular-scrollie.min.js"></script> <script src="angular-snapscroll/dist/angular-snapscroll.min.js"></script>
snapscroll to your app's module dependencies:
And now you can add a
snapscroll attribute to any element to make it
snap-scrollable! The element would have a scrollbar to begin with, the idea being
that with the
snapscroll attribute you're adding scroll-and-snap behaviour to
an element that is otherwise already scrollable:
<div style="height: 200px;" snapscroll=""> <div style="height: 200px;"></div> <div style="height: 200px;"></div> <div style="height: 200px;"></div> </div>
All you need to set are the heights of the snapscroll element and it's children
(you can also use the
snap-height attribute for that).
To have the element fill the browser viewport height:
<div snapscroll="" fit-window-height=""> <div></div> <div></div> <div></div> </div>
I recommend using angular-swipe to add touch support but you can use any other library or module that recognizes vertical swipe gestures (e.g. hammer.js). Here's how to do it using angular-swipe:
<div ng-init="snapIndex=0" snapscroll="" snap-height="200" snap-index="snapIndex" ng-swipe-up="snapIndex=snapIndex+1" ng-swipe-down="snapIndex=snapIndex-1"> <div></div> <div></div> <div></div> </div>
If you have nested snapscroll instances, remember to prevent the swipe events in a nested instance from bubbing up to the parents. See the demo for an example (the demo uses angular-swipe).
- snapscroll as an element - would allow use of templates and ngAnimate for animations. Currently this repo has a (rather outdated) 'as-element' branch for this.

This project uses Grunt for automation. Once you've forked the repo and cloned it to your machine, run this to install all the dependencies:
Then to continuously watch files and run tests as you write code, run:

grunt build etc).
