This repository contains a code to provide compatibility layer between Polymer 3 and Polymer 2. It allows to run Polymer 2 application on top of Polymer 3 without changing a code.
The repository is added as a submodule to gerrit project; polygerrit-ui/app/package.json references a local folder (with submodule).
folder will be removed after full switch from Polymer 2 to Polymer 3.
Some files have code related to google-closure-library, but it is not necessary to use google-closure-library - the polymer/lib/utils/boot_bridge.js file provides placoholders for it.
Note: it is expected, that this repository is used only during transition period (Polymer 2 -> Polymer 3). After the transition is complete (including plugins), the submodule will be removed from gerrit repository.
