QUESTION
I'm trying to grab the content of the following url: https://docs-05-dot-polymer-project.appspot.com/0.5/articles/demos/spa/final.html
My goal is to grab the content (source code) of the webpage as seen by the visitor, so after it has rendered all javascripts etc.
To do so I used the example mentioned here:http://techstonia.com/scraping-with-phantomjs-and-python.html
That example works on my server. But the challenge is to also have it work for polymer based SPA sites like the one mentioned. Those are really rendered javascript websites.
My code looks like:

QUESTION
I'm trying to get a loading screen to work in Polymer, as seen in this Gist: https://gist.github.com/SlicedSilver/f2e93a5995f84d9cd512
The idea's pretty simple: the entrypoint is a lightweight HTML file that renders the loading screen, whose body contains an onload callback that loads up the Polymer app via the DOM once that lightweight page is rendered.
It works beautifully on desktop browsers. On mobile browsers the filestoload.html is never getting loaded (but also isn't throwing any errors), so the loading screen just stays there and the app never loads. The full code is below, but particular attention goes to this line:

Answered 2017-Feb-25 at 01:30Turns out to be some kind of bug in the Polymer build, probably related to another error where running polymer build
was resulting in the app throwing a bunch of 404 errors from bower components.
When I did a raw deployment (without building/vulcanizing) to the server, everything worked fine on both desktop and mobile, and without the errors.
QUESTION
When developing polymer webcomponents, I eventually run them through vulcanize to be served on production. unfortunately this causes a issue for me when I would like to use two separate bundles.
I have for example a base.html
file that contains all the main imports that
will be used across the site, on every page. I vulcanize this as
base.build.html
.
Then for different pages, I might have a custom import just for that page eg.
contact-page.html
Both of these are loaded in

Answered 2017-Feb-16 at 20:56Without seeing the error messages you get, I assume the issue you have is, that your extra imports include elements (and most likely polymer.html) that are already bundled in your vulcanized base package. And Polymer throws an error when it tries to initialize the same element twice.
What this means is that you usually can't mix vulcanized with non-vulcanized packages.
Getting multiple vulcanized packages to work together can be very tricky as well, and you will have to play with the -exclude
and/or -strip-exclude
option of vulcanize to make sure no elements (and their dependencies) that are included in the first bundle will be included in the second bundle.
QUESTION
I have been creating several custom Polymer-based web components which will allow third-party websites to embed content from our website on their site (think glorified iframes or a Google Maps widget). I am in the process of moving my components from my local dev environment, where they are working fine, onto our remote test environment. However I have run into an issue that is making me wonder if I have misunderstood how web components can be deployed and invoked.
My hope/assumption was that I would be able to "build" these web components into separate javascript and html files (using vulcanize and crisper) and then I would be able to host the resulting *.js and *.html files on my public server. Folks who wanted to embed some website content from my site on their site would use my webcomponents by referencing my Javascript file, for example:
...ANSWER
Answered 2017-Jan-24 at 23:11Loading remote web components is permitted, I've done that with a few projects. Users of your components should do the following:
- Load the web components polyfills, if necessary
- HTML-import your built components
- Use the custom elements in their webpage
The vulcanized JS should be included by you in the HTML file the users import, not directly referenced in the user's HTML page.
