clone the repo

git clone git@github.com:meteorwebcomponents/synthesis-meteor-polymer-npm-demo.git

npm install

Do not use meteor npm install. Instead use npm install @polymer/components-name

Load components.

Load webcomponents and polymer before everything else.

/* imports/ui/index.js */
import "webcomponents.js/webcomponents-lite.min.js";
import "@polymer/polymer/polymer.html";

Load third party components you use on the go.

/* imports/ui/components/test-element.js */
import "@polymer/paper-button/paper-button.html";

Note that you cannot use <link rel="import" href="@polymer/component/component.html"> from html files since synthesis considers link import paths as relative. You can give absolute path(relative path from root directory) as href though.

Load your components using import/require from js files. You can use link imports from html files.

/* imports/ui/index.js */
import "./components/test-element.html";
