Polymer + page.js flash notifications with paper-toast - polymer

Question

I'm building a mid sized app with Polymer and used the Polymer Starter Kit to kick things off which uses page.js for routing.
I want to implement flash message functionality using the paper-toast element.
In other technologies/frameworks this is implemented by checking to see if a property exists when the route is changed.. if it does, it shoes the relevant flash/toast message.
How... with Polymer & Page.js is it possible to replicate this type of functionality? Page.js doesn't seem to have any events for changed routes.
The only way I can think is to create a proxy function for the page('/route') function that I have to call every time I want to go to a new page which then calls the actual page function. Is there a better way?

Answer 1

I've implemented this like follows for the time being... seems to be ok but if anyone can suggest improvements let me know.
In routing.html
window.addEventListener('WebComponentsReady', function() {
// Assign page to another global object
LC.page = page;
// Define all routes through this new object
LC.page('/login', function () {
app.route = 'login';
app.scrollPageToTop();
});
....
//implement remaining routes
// page proxy... to intercept calls
page = function(path) {
// dispatch event
document.dispatchEvent(new Event('LC.pageChange', {path: path}));
// call the real page
LC.page(path);
};
});
Then where you want to listen.. in my case in a lc-paper-toast element added to the index.html file of the app I can now listen to when the page is changed...
ready: function() {
document.addEventListener('LC.pageChange', function(e){
console.log('page change' , e);
}, false);
}
Only thing to be aware of is that all page changes must be called with page('/route') otherwise it won't go through the proxy.
