javascript - Calling shared services or libraries from a Polymer 1.0 custom element -


with angularjs it's possible share functionality between directives e.g. injecting common service each directive wishes consume it.

i'm learning polymer 1.0 custom elements , wondering how shared javascript service/library consumed custom element? service/library isn't 3rd-party can modify please, should possible invoke legacy/non-polymer code.

examples of shared services dialog service, or service responsible formatting date/time etc. offer arbitrary behaviour may involve remote call to, say, web service.

what best practices in regard? implement behaviour described in following link?

https://www.polymer-project.org/1.0/docs/devguide/behaviors.html

the javascript functions in polymer element can consume library available them. libraries expose global variables through can consumed, e.g. jquery's $ , lodash's _ can used globally. similarly, library can expose global variable, e.g. mylib through can consume api, e.g. mylib.formattime, mylib.dialogservice.

polymer behaviors typically used sharing common functions between polymer elements.
