2. Page A short Angular narrative › Mr White: I’m trying to set a variable on my scope and it isn’t reflecting in the UI. › Mr Blue: I ususaly just use “if (!$scope.$$phase) $scope.$apply() “. › Mr Red: Don’t do that! You should use “$timeout()”, because “if (!$scope.$$phase) $scope.$apply() “ is an anti-pattern. › Me: THAT IS ALL AWFUL. / Copyright ©2014 by Readify Pty Ltd 2
3. Page Inspiration › Given angular v1 is effectively obsolete* › And given my recent pause for thought › And given there is a lot of noise around React as a front-end framework › When selecting a front-end framework for a new web project › Then [Insert conclusion here] * http://www.techinfine.com/post/231575/Announcements-from-ng-confsome interesting news at ng-confjust last week has injected some hope into Angular V1, although at the moment it is just that –hope. / Copyright ©2014 by Readify Pty Ltd 3

11. Page Authentication › Like the angular apps implementation of this cross cutting concern, leverage routing to enforce auth. › Use a mixin to inspect and redirect for auth. / Copyright ©2014 by Readify Pty Ltd 11

14. Page Flux and async › Handling asynchronous interactions with the server is easy enough with Fluxxor, but isn’t strictly in-built. › Need to dispatch actions on start, done and fail of interaction, and stores are used to supply state that the view can use to inform the user that things are happening. / Copyright ©2014 by Readify Pty Ltd 14
