Build using Polymer with Polymer toolbox.
Install polymer-cli:
npm install -g polymer-cli
This command serves the app at http://localhost:8080 and provides basic URL
routing for the app:
cd to path-to/web-app
polymer serve
This command performs HTML, CSS, and JS minification on the application
dependencies, and generates a service-worker.js file with code to pre-cache the
dependencies based on the entrypoint and fragments specified in polymer.json.
The minified files are output to the build/unbundled folder, and are suitable
for serving from a HTTP/2+Push compatible server.
In addition the command also creates a fallback build/bundled folder,
generated using fragment bundling, suitable for serving from non
H2/push-compatible servers or to clients that do not support H2/Push.
polymer build
This command serves the minified version of the app in an unbundled state, as it would be served by a push-compatible server:
polymer serve build/unbundled
This command serves the minified version of the app generated using fragment bundling:
polymer serve build/bundled
You can extend the app by adding more elements that will be demand-loaded
e.g. based on the route, or to progressively render non-critical sections
of the application. Each new demand-loaded fragment should be added to the
list of fragments in the included polymer.json file. This will ensure
those components and their dependencies are added to the list of pre-cached
components (and will have bundles created in the fallback bundled build).
